[beginner] forcing asynchronous functions to execute synchronously

Hey all! (TLDR at the bottom if you don’t care for context)So I’m not new to programming, but I’m definitely new to node. My background is in languages like C# and Java, just for context; basically nothing web-based.Recently to help teach myself the language, I’m putting together a hobby app. The premise isn’t important for the moment, but I’ll be doing a whole lot of interaction with a database full of information.It’s a pre-existing dataset that I’ll be working with, and it has about 26,000 records in it. The issue is that before I can actually use that data for what I want, I need to take that raw data and combine it into a wholly different data format, which will group a lot of those records together and do some math on them. To help visualize, it’s sports data, and the initial raw data I have is every historical season individually - so a player, a year, a team, and stats for that year. So one player could have many different seasons. I want to create a new data set organized by player, and each player document will have an array underneath it with all of their associated seasons.So the organization and transformation piece isn’t so bad. I’ve successfully gotten it to take in a season, validate whether or not it already has a player created, and then appropriately either create a player, create a season under a player, or nothing for duplicates.The problem comes in now running that for the entire DB of 26000 records. You can assume what happened: I query for all records, send that array to a function, and then attempted to just do a foreach over the array and call my converter function for each case.And of course, that didn’t work. It sure did call the function about 20000 times, but I think I functionally overloaded my DB with requests, and finally mongo just force-closed the connections, and it didn’t finish. I configured mongoose to allow me 20 open connections, rather than 5; I also upped the timeout to 10 minutes. Got more stuff done, but ultimately the same thing happened.Moreover, since I do kinda need to do this in order (so that player objects can be created, and then latter objects can come in and be grouped under the first object), I’d like a way to do this synchronously, or at the very least, do it in small batches with a configurable delay. I don’t actually care if it takes 5 hours or something - this is just a one-time process to get my data in place the first time, so I can actually do a cool thing with it.So TL;DR - how do take asynchronous actions (I.e, interacting with MongoDB) and make them synchronous so they execute in sequence? I’m using mongoose for schema and models.

recommendation for super productive REST API framework

I'm looking for a framework that can help me quickly build a restful API that exposes a typical relational data model. I'm concerned more with productivity than customizability. Ideally I would like to be able to define a data model and have migrations, data access, routing all abstracted away. I'm not sure such a thing exists, but I would like to get as close to that as possible.

Twitter API Help

I'm working on a project that uses the Twitter API, and I've been able to learn how to get authenticated with Passport.js and implemented sign-in via Twitter (The Net Ninja's tutorial on Youtube was a life-saver). However, I've been stuck for the last couple of days on trying to figure out how to authenticate further requests with the twitter API past sign in. Such as following users, posting tweets, anything that really requires a User Access Token and an OAuth Signature. The twitter api docs for following users haven't really been much help as I'm new to the "Authentication" part of web development. Does anyone have any tips that could help me get out of this rut?

[Help] The best strategy to check for users in passportjs async workflow

I am new to node development and authentication with oauth. I'm using passportjs with a oauth strategy in a express app. I need to check if the user exists in my API (decoupled from the backend) so my initial thought was check for users in the passport strategy callback with an API call, but I have learnt that await and a callback cannot be used at the same time.Later I thought about transferring that responsibility to the frontend (React). I mean, return the opendid details to the frontend and do checking in the API (GET user, if not user POST user).Is that a good or recommendable approach?

GraphQL Questions (Prisma2)

Hi All,I've been looking into graphQL, particularly Prisma2 and have a few questions. I'm trying to get my head around the overall architecture, it's quite different to what I've worked with before (JSON APIs)[1] Business LogicIn a JSON API, I'd create an API endpoint to allow a user to sign up (this might kick off some async tasks and e.g. send an email).It seems like in graphQL architectures, mutations are used to provide the equivalent of an API endpoint, where business logic would be implemented (e.g. user sign up). Is this correct?I'm trying to understand how a system would be implemented without using express to provide API endpoints that would implement business logic and make calls to the graphQL layer via e.g. PhotonJS.[2] PhotonI understand that photon is a generated library to allow you easy access to your graphQL interface, but is this really only intended for usage on the server? Can this be exported to be used in e.g. an Angular 2+ project?It also seems that the generated photon client doesn't include mutations, so I'm a bit confused as to what the intent is with it.Any input would be useful :)Thank you!

Does Node cache/memoize function calls?

Long story short-ish: I have a Node project, part of which exposes an endpoint to get a list of timezones with their UTC offsets at that precise moment. In the UK (where we're based), before 01:00 UTC on 27 October (when the UK leaves British Summer Time), the endpoint should return '(GMT+01:00) London', and after, it should return '(GMT+00:00) London'.The problem is that if I start the process before 01:00Z 27/10 and then call the endpoint after, it still returns '(GMT+01:00) London'. I simulate this by manually changing the system time.The data is generated by a function call that calls a formatting library that wraps Moment Timezone to generate the data. IIRC, unless its overridden, Moment will assume that the time you want is the current system time. So why, when I hit the endpoint after 01:00Z 27/10, does it behave as though it's before 01:00Z 27/10?A possibly related tangent: I inserted a console.log() in the function call to check the arguments and default values. I expect it to output whenever I hit the endpoint. In reality, it outputs to console five times as soon as I start the process, and then never again, no matter how many times I hit the endpoint.So the question is: is Node implicitly memoizing this function call, somehow?I understand this is an odd one, but if anyone has any experience of this or something like this, I'd be interested to know!

(Functionality that one might just utilise for “node licensing” and authentication)I had assumed that Node would allow me to import native headers for things like fs and crypto (similar to how I’d require() then in JS) but I can’t find any definitive answers or more advanced examples that cover this functionality in a way I can follow.I’ve seen some references to libsodium online for crypto but is it really necessary to be adding third party libraries for this?Thanks all, hope to hear from you soon 🙂

[Help] I am very confused. Need some help to start.

I'm fairly new to the world of Node.js and I have some questions because I am greatly confused.I did a project via Online Courses in Udemyhttps://yelpcamp-web-coders.herokuapp.comWhat got me confused, is that I read blog posts, did a number of google searches, and I found billions of courses, books, blog posts, technologies and this is where I am really greatly confused and I really need to sort them on my head.The only solution for me right is to create something on my own without any other courses, I really got tired.Doing courses and homework is easy, for example: write a sort function, make some classes or objects, sort by age, create some eventListeners and so on. But what happens when you want to make a Full Stack Web App? And that's exa ctly where I'm stuck.In the above project which was created on May, that project used Javascript 5 but that's ok. I learned a little bit of Node.js, npm, view engines and somehow managed to do it.For starting I would like to write/create my own blog.I know I can create a blog with Static HTML/CSS/Javascript and some JSON files but I want to do something more complex like for example, when I or the user visits the following url:/blog/posts // Select only the Title and a Short Description from the Table Posts/blog/posts/post_id // Select all from the selected titleMy goal is to use 2 tables, the 1st will contain only id, post_title and the 2nd will contain the post, date_created, primary_id, foreign_key (id from the 1st table) and will make them appear on my browser will relationships and I will also add comments from users via a different table. I'm sure with this I will be able to handle some databases to make my beginning.Now, these are my problems:Is node.js good for MySQL or PostgreSQL?Which Template Engine should I use? I searched and I found many people mention Handlebars, pug, ejs. As I mentioned I want to be able to pull data from a database and make it appear to the user. What is the best to be used with FrontEnd, I want for example something like: Where and will get them from the Database, also I would like to learn Angular and ReactJS in the future, How can I render my webpages with ReactJS or Angular, do I have to use a template engine like ejs and combine ejs with React or is there any different way?3) Should I learn webpack? I read webpack's description if I understand correctly, if for example I have billions of CSS and JS files, webpack combine all of them and serve only 1 CSS and 1 JS file to the end user, is that correct?4) Should I learn Docker?I have 3 PCs, A desktop with Windows, A laptop with Ubuntu and VPS with Ubuntu Server, if I have understood correctly, with Docker you create a container, throw your app, nginx, MySQL server and with a command you are done.I know how to create services, install apps on Linux and I think it might be a lifesaver if I want to change VPS and for testing purposes to all of my machines (I think so)

Send JWT and redirect to another page in a single step ?

I'm using express.js to build a website. Everytime a user logs in, I generate a JWT, which is use to authorize all further activities the user does. For this I must receive the jwt as a request header, which means the user must have access to it through the frontend, so every generated jwt (after each successful login) must be sent back to the user.The problem is, I want the user to also automatically be redirected to the home page, something which requires use of res.render or res.redirect. how can I make sure the user gets back the jwt after logging in and then also gets redirected to another pageP.S. I've tried adding the jwt token as part of the header for redirect but that has not worked, the user simple gets redirected to the home page, but I can't see the jwt arriving in the headers when I test it on postman.Also, methods like appending the jwt as a search term in the res.redirect URL are also not an option, because the Auth is not a one time thing, I need the frontend to have access to the jwt for all further requests to get authenticatedI know cookies is a solution, but I'm hoping for a something cleaner that that, because there's a chance I may be redirecting the user across two different daomains at one point, in which case I don't think cookie would be a viable solution anymoreAny help is appreciated, thanks is advance !

[Question] REST API Routes and Role Protection

I have a question about API routes and roles. Assuming a "simple" microservice architecture.So let's say there's a User role and a Admin role. Each have their own client frontend.The user can create a /POST /api/posts/create. However, the user can only have access to certain features when creating that post. Then, let's say the user wants to have access to a certain feature in /api/posts/create, BUT this is for Admin roles only. So the Admin decides to login to their own Admin account, and create the post for the User (so the admin is creating the post on the User's behalf).In a typical REST API (shown by most internet tutorials), it would be something like saying....Routes File:router.post('/api/posts/create', [isAuthenticated, isAuthorized], myController.createPost);Controller File:createPost: function (req, res) { var newPost = new Post(); newPost.title = req.body.title //etc. newPost.save(); //Saved to DB } So, because Admin has access to certain fields (or the "right" to do something extra) on the same route (again, assuming microservice), does this mean I would have to do some kind of switch statement or conditional statement within the createPost() and have somewhat of a duplicate lines of code or am I supposed to make a new function specifically just for Admin level account users to access or something else? Because if I were to code createPost with the limits of User, then if Admin access the same route, the Admin is limited by the same things as the User. However, if I coded it for Admin, then User can perform just as much creation as the Admin on the same route....

Mongoose as your primary schema

In most articles related to Mongoose, Mongoose schemas seem to be the Primary schema. This seems to me like a mistake. The schema definition is coupled with Mongoose and Mongoose is written in NodeJS. In my humble opinion, the ideal Primary schema definition should be portable and use a well-known standard that crosses the boundaries of programming languages and networks. REST API using Hypermedia can use this schema to share metadata of return resources. Mongoose does schema do not fit this requirement. Instead, a mongoose schema should be derived from the Primary Schema. A good candidate is JSON Schema. However, I noticed a reduction in mention of JSON Schema in Google searches. Anyone using JSON Schema? What challenges you faced with while using it?

I have been working on building Vault as a Service (an online service for storing passwords, keys, certificates, tokens and really anything that’s supposed to be secret). I'm about to release it and looking for early adopters. More details inside

I moved to application security from software development and we’re (including myself) all guilty of storing passwords, secrets, credentials in source control. Storing sensitive data in source control exposes it to everyone in your team, including contractors and temp developers. In addition, sometimes we make our repositories public and forget (we’re all humans at the end of the day) about the credentials we store in code, hence exposing our credentials to everyone.Attackers search GitHub for tokens & sensitive information, and it’s one of the most common ways of stealing credentials.Some teams use .gitignore to exclude credentials however this creates new challenges such as distributing all keys among team members, etc.We have been storing credentials in our source code not because we don’t know any better, but because there hasn’t been really a good service for us to use.I know the first concern you have is why on earth do I trust you with my most sensitive information? We use public/private key encryption, hence don’t even know what you store in your vault. It’s encrypted with your public key, and only you (as the private key owner) can decrypt it. This is similar to how password managers, such as 1Password and LastPass work.There’re other vaults available, but in order to use them, you still need to be familiar with security concepts, and they’re too complicated. Some of them won’t even let you use them, unless you engage with their stupid, sales team. Seriously?I’ve been working on building Vault as a Service for the past 2 years, and below are some of the features we already have:Easy to use, simple UIWe wanted to build something that’s beautiful, and super easy to use, hence our service comes with a simple, beautiful user interface. Security doesn't mean the UI supposed to be ugly!No sales team.You don’t (ever) need to talk to our sales team. We actually don’t have one. It’s free for all open-source projects.Key RotationEasy to change keys without ever making any changes in your source code, or deploying anything.Auto Key ExpirationSometimes we want keys that will be available for a short amount time. Or if there’s a key that’s not being used by any application for over X amount of time, we can automatically invalidate it. Attackers look for legacy systems initially, because these are the systems no one cares about. So if there’s a legacy application that’s no longer in use, we can automatically disable the keys for it.Key GenerationGenerating a secure key is not a trivial task. Our vault handles this for you, by simply asking “give me a secure key”.Detailed Audit LogsRemote Access ACLYou can make your vault accessible by only certain IP addresses which increases security. Even if someone steals your master key, they won’t be able to access your vault.Encryption as a ServiceEncrypting data is also not trivial, what key size to use? AES or RSA? Just ask your vault to encrypt your data securely, using industry standards! That easy.Namespaces / Multi ProjectsCreate/Manage vaults per project, namespace or application. Use different keys for your development, staging and production environments.Would you be interested in using it in your project? If so, please comment below and I’ll get in touch. Thank you!

My experience with node and best practices in one repo

You can find the repository here https://github.com/feredean/node-api-starterOver the past several years of working as a full-stack developer, I realized that very often I find myself taking a peek at past projects to refresh my memory when it comes to structure, various project configuration or implementation. After taking a look at popular projects like https://github.com/sahat/hackathon-starter or https://github.com/microsoft/TypeScript-Node-Starter I realized that they are not quite what I'm looking for. What I wanted was an API designed for app consumption. With this in mind and the projects mentioned above as a guide I started working on yet another node API starter (along with it's own example app!). When I started I had the following things in mind:fully configured development environmentuse async/await over callbackscreate integration tests with over 80% code coveragesupport CI and CDact as a repository of "examples" as well as a starter kit for creating applicationsAt this point, I have more or less achieved what I have set out to do and decided it's time to reach out to the community in order to get some feedback.

Alternatives to Loopback 3?

Hi all,I've built a few projects with Loopback 3, which although I love the idea, seems to fall short in a few places. Loopback 4 may solve some of these issues, but it doesn't have feature parity with 3 yet, so I'm looking at alternatives.Things I like about LB3:- Built in user/roles/authentication (massively helpful to have this built in)- Can generate an angular 2+ library for the front end to access all APIs and objects- ORMProblems- Documentation (lack of/confusing in places)- Some stuff missing from ORM- A lot of issues getting intellisense to work in VS code!Any suggestions of node frameworks that could provide the above, ideally with typescript? Having users/roles/auth out of the box is a big one for me as I do a lot of proof of concept projects, as is the ability to generate an angular 2+ library for my front end. Ideally built around express and strong ORM like sequelize.Any suggestions?Thanks!

How can I reduce the boilerplate for my UI projects? (Webpack+Pug+SCSS/LESS+...)

When I need to write a GUI for my node projects I like to stay vanilla instead of using big web framework.Usually I define the DOM using Jade or Pug, manipulate it using the standard browser JS API and tweak the style with SCSS or LESS.I then pack everything together (including node code and libraries) using Webpack.I'm a bit bothered by the amount of boilerplate that goes into every project with an UI though. In fact I always end up with:Many many extra dependencies (e.g. css-loader, node-sass, sass-loader, style-loader, pug, pug-loader, html-webpack-plugin, copy-webpack-plugin, to-string-loader, webpack, webpack-cli, webpack-dev-server and usually more).A 50+ lines webpack.config.js.Several NPM scripts in my package.json to start, build or test the web assets.Normally I copy and paste all this stuff from previous project and only modify what's needed. That takes several minutes, feels very repetitive, the package.json becomes all cluttered and I hate how much code is duplicated between my various UI projects. This happens even with the tiniest UI projects, while it's rare with pure Node.Would anybody have any ideas on how to remove all this boilerplate?

Creating a web app in node to host and deliver misc Excel Reports

Hey, what's up? At my work, we currently use a Grails/Groovy project to host a website where managers and other employees can log in and download reports and if they wish, subscribe to reports that are outputted into Excel. Outputting the raw data is easy enough, but sometimes we get report quests that pretty much simulate what Pivot Tables do in Excel. This is where it is currently tedious as we are grouping the raw data into hashmaps then outputting that data in a similar format using nested key:value pairs. We currently have to keep track of row indexes and column indexes and it can quickly become confusing.We are leaning toward using Node for the future and I was reading a little about excel4node and xlsx. My question is what do you guys think about moving toward Node and also if there is any library or framework I can use (maybe excel4node?) that could make pivot tables easier to handle and output. Sorry if this is confusing as I am pretty new to the project. Thanks.

Suggestions on how to overcome the challenges of Dynamic language

Sorry for the long title tried to make it as explanatory as possible.​I am a long time C# programmer. I have never worked on any application run on HTTP protocol but have done many networked applications in past. Currently I have an client who offered a job to port their in-house surveying system's admin panel get ported to web. So basically I need to port an .NET2 application to the web and make that web application be compatible with their already existing authentication database and all that stuff etc etc.​My problem is that even though I worked with sockets and networks in a very simplistic manner in C# I have never done ASP.NET yet alone HTTP. Now the first issue with this is that, client decided to port the application web because they have decided to not use any Windows Servers anymore. Lucky for me .Net Core supports ASP.Net but unlucky for me I hated every single thing about ASP.Net. I mean 'to me' it is disgusting... I asked them what languages would they want and client said that they want either C# with .Net Core, Django or Node.JS environment. Now c# is out of options, I hated ASP.NET. Django is... Meh in my opinion. It is a great framework but I dont like tab spacing dominating my code. I am more of a control paranoid and I want brackets. When I checked NodeJS I saw that it is a great runtime environment. It's syntax is clean and follows the same sexy principles of JavaScript. plus Node being async is just too good to pass even it only runs in single thread. It's such a powerful thing especially if you are writing an back-end which queries tons of stuff all the time.​Here is where my ACTUAL BIG problem starts:It has been little bit more than a week and I am starting to step into serious issues here and there. At first, JS being a dynamic language gave me a whole new powers. I can manipulate things like I could never done before. At the beginning this is great but as the code gets bigger and bigger and bigger and biiiiggeeerrr this starts to become a issue. Especially if you have other people coding together with you. If you have ever worked with a team you know that following a strict style in your code is really important at big projects. This is true for everything I guess. The more crowded a community the more strict rules you need. This applies everywhere. The dynamic structure of JS really started to cause serious problems for me. My coworker is changing the variable type without knowing what it was before and suddenly the JavaScript engine tries to parse a string as if it is an integer because the parser I built was specific for integers.​It is impossible for me to be the first person encountering these issues. I wanted to get the feedback of you all on how did you manage to overcome these issues. In a community discord that I am a member of I asked the same questions and people said that "TypeScript is a great solution for this but if you are writing back-end in Node TS might cause issues in your code."To me TypeScript not being able to work well with Node is not possible. It is supported by Microsoft. I dont believe it is true but I also dont want to risk it either. Can I get all of you people opinion on this?

How do I use jsdom with a URL instead of a string containing HTML code?

On the jsdom npm package page, the following example is given:const dom = new JSDOM(`

Hello world

`); console.log(dom.window.document.querySelector("p").textContent); // "Hello world" Another example is given for using a URL instead of a string:const dom = new JSDOM(``, { url: "https://example.org/", referrer: "https://example.com/", contentType: "text/html", includeNodeLocations: true, storageQuota: 10000000 }); However, every other example seems to use the first example as a template instead of the second. Further, when I run console.log(dom) on the first example, I can see that dom contains data. However, when I run console.log(dom) on the second example (using an actual URL), dom is set to null.I'm having trouble finding guides on how to use this package, and the stuff I'm finding appear to be older, referencing jsdom.env and other things that the npm page I linked doesn't do. Could anyone tell me the correct way of using this package with a URL, or point me to a good guide or documentation for this package?

I haven't seen an example of what will be expected though (maybe I haven't dig deep enough to find something?), would be interested in an example.Source: https://openjsf.org/blog/2019/10/22/openjs-foundation-launches-new-professional-certification-program-to-support-the-future-of-node-js-development/​EDIT, best description I found so far: Exam tasks instruct you to complete a step, or a series of steps, which may be answered with Node.js core API’s or with any Node.js libraries/frameworks of the candidates choosing.

DRY form field definitions in express

Coming from a monolithic CMS background (Drupal, Wordpress, etc), I've got a question for those of you building on a modern stack. Recently I've been building a decoupled app using a js framework on the front and node(express) rest api on the back. The dev experience overall is GREAT compared to the oldschool PHP world. That said, I have one pretty big pain point that I'm wondering if anyone else has solved:With oldschool CMS' if you want a field on a piece of content, you add a field, give it a name, hit save. Easy. With the new architecture however the process is as follows: first, add the field to your form, then add the field to your front end model, then add the frontend validation for the field, then add the frontend submission handler for the field, then add the backend submission handler, then the backend validation, then add the field to the backend model, and finally write backend migrations for the field - and this isn't even including the use of a store, which you probably will. In all you've created at minimum 8 different files, spread out over two codebases, with a ton of duplication/replication throughout.Is this really what people are doing every time they want to add or update a field? This seems crazy to me. I feel like there should be some way of defining your fields/models ONCE, in a single file, and then have that file be used by the front and backend, for everything from form building to validation and submission. Is there is some sort of industry standard practice for doing this that I'm missing? The process described above seems unnecessarily complex and not at all in line with the DRY approach. Why is basic CRUD this messy?Someone enlighten me please!

[HELP] Testing and deployment platform

I am deploying my app manually right now for my clients. Deployment process is pretty straight forward:Run testsCopy to target serverCopy customer's config.js (with customer specific things)Copy customer's assetsRestart the http serverThe same for ReactJS frontend (except config needs to be copy locally first and then production build is create).So basically, everyone is using the same code base with different assets and configs.Currently I have only a few customers, so I created simple shell scripts which do everything for me. However, I am counting on gaining new customers soon. The product is dynamically developed and updates are quite frequent. Thinking a little bit in the future, I am looking for a platform that would help me automate these tasks: testing, building, deploying, set up configs etc.Is there such a tool (preferred free/open and self hosted)?I would be grateful for guidance if someone has experience with a similar case.

How can I reduce the boilerplate for my UI projects? (Webpack+Pug+SCSS/LESS+...)

Sometimes I need to write some GUI for my node projects. It's beautiful how easy it is to integrate software written in node in a Web environment.I prefer to stay vanilla, and not use any big web framework. I'm usually writing my HTML with Jade or Pug, my styles with SCSS or LESS and manipulate the DOM using the standard browser JS API. I build all the JS code (including the node stuff and the dependencies) into a single JS file for the web using Webpack. I absolutely love this environment and the workflow.I'm a bit bothered by the amount of boilerplate that goes into every project with an UI though. In fact I always end up with:many many extra dependencies (e.g. css-loader, node-sass, style-loader, to-string-loader, webpack, webpack-cli, webpack-dev-server, usually even more).a 50+ lines webpack.config.js.several NPM scripts in package.json to start, build or test the web assets.I usually just copy and paste all these things from previous project, and only modify what's needed. That takes several minutes, feels very repetitive, the package.json becomes all cluttered and I hate how much code is duplicated between my various UI projects. This happens even with the tiniest UI projects, while it never happens in pure Node.Would anybody have any ideas on how to remove all this boilerplate?​I've considered the idea of creating a metapackage that installs all the dependencies I usually need and offers a precooked webpack configuration that I can just require and, if needed, tweak. This solution seems quite hacky though... What's gonna happen if I decide to start use something else instead of Pug and SCSS, if I want to update some dependencies or if I start preferring different defaults? My metapackage would quickly become bloated with tons of dependencies even though each specific project only needs a few. The defaults would either become obsolete, or would break older projects...

Should data validation be handled within the definition of a class, or before creating a new instance of the class with that data?

Let's say you have a class that will be the structure of some data that you will then insert into a database with a function within the class like this:class Player { constructor (playerName) { this.playerName = playerName; } insert() { connection.query( "INSERT INTO Players (playerName) VALUES (?)", [this.playerName] ); } } const userInput = getUserInput().toString(); const player = new Player(userInput); player.insert(); Now let's say you decide names can only be 24 characters long and want to handle the validation somewhere in this block of code.Should you validate the data before creating the new Example instance, or should you create a function to validate the input inside the class definition?

How do you implement sharding in a Node.js, Express, Mongoose application?

https://mongoosejs.com/docs/guide.html#shardKeyThe documentation doesn't say much, I think the shard key takes for argument the fields in the schema you want to use for the key, but the example given should only work for the range-based sharding if I understand correctly.https://docs.mongodb.com/manual/reference/method/sh.shardCollection/I thought I had to implement my own logic for sharding, but it seems I just need to modify the schema when using it with Mongoose. The things that aren't clear however is how to use hashed sharding? Is it done configuration side? The doc says we need can only use 1 field, so does that mean it won't work if we provide 2 like in the example given?Also, how do we configure this properly if we use MongoDB Atlas?

What techonolgies/ORMs do you use for production/enterprise any why?

The title should say "and", not "any".I want to be able to build production-grade applications that have a clear separation between a domain model and a database entity. That is, I should be able to migrate ORMs, databases, etc., without having to touch domain logic. Thus, I want to utilize the Data Mapper pattern, not Active Record, as well as Repositories.TypeORM seems to sprinkle RBMS specific decorators across your entities, meaning you can't easily separate a domain model/entity from a database model/entity. I could build my own Repository around Mongoose, but then schema is being duplicated and validation logic has to be synced across the schema and any other models.These are my current issues, and maybe a basic query builder like Knex is a better option, but I'm sure that production-grade applications must be able to leverage MongoDB and still have a clear separation of concerns as well.So, what methods have used to get around the problems I'm facing? What are your preferred database systems and ORMs (if any) in production? How do you ensure a clear separation between the domain layer and persistence layer, etc., for your production applications?I'm working in TypeScript, personally, which is probably a better option for this kind of work anyway.Thank you.

node-powershell + active directory ps1 scripts = ghetto ADUC API?

instead of reinventing the wheel, im just curious if there could be a way to reuse all my powershell scripts, but just route them up in Express to run server side then spit back some JSON to the client end for display....then CRUD my way into an active directory api. ive messed around a bit using node-powershell, running some different scipts, and getting used to how the output works...but it seems doable, still trying to understand the output part.so im always leery when it seems like im the only one wondering stuff...i havent seen hardly any chatter about using this node-powershell package as a way to get a really easy ADUC api going. You already have all the powershell cmdlets there, or any personal scripts...i figured it was worth a try, or either start learning ldapjs, which im not sure im up to right now. i have lots of enable or disable scirpts i use when folks hire on, or get termed, that goes out to a lot of extra endpoints to turn down other accounts and do cleanup, we're O365/hybrid...sure would kick ass if I could reuse those.OR, is there a more optimal way of invoking ps scripts server side using node.js/express? none of the ps1 scripts i use run over 15-20 seconds, not huge cpu crunching or anything, mostly just waiting for aduc to talk back, or when reaching out to other API's, which i'd probably bring those out of their ps1 scripts and do the fetching from express directly.....but the AD stuff seems doable if there isnt a gaping security angle im not seeing yet...

modular-aws-sdk-pure-node: the aws-sdk without any clutter

I have developed a lot of node.js services running on AWS (EC2) and using the aws-sdk. What always had bothered me is the size of the aws-sdk! Annpm install --save aws-sdk gives you 43 megabytes of full blown aws-sdk. I peeked inside the installed folder, and behold, there is a lot of stuff I, as a node.js developer, don't need: dist, dist-tools, files for supporting the sdk running in the browser.So, I wrote a small script (https://github.com/Junkern/modular-aws-sdk/blob/master/scripts/createPureNodeJsAWSSDK.sh) which gets rid of not needed files and folders and I published the resulting package. Installing the modular-aws-sdk-pure-node package (https://www.npmjs.com/package/modular-aws-sdk-pure-node) now results in a size of 30 Megabytes.This is, however, still a lot, especially when you are using only one service (e.g. DynamoDB) of the SDK.So, I analyzed the aws-sdk and found a way to create the whole SDK for only one service! When you use only the DynamoDB, you can save ~40 megabytes by installing the modular-aws-sdk-dynamodb package, instead of the aws-sdk. (Take a look at https://github.com/Junkern/modular-aws-sdk to find out more)I am a huge fan of keeping applications small, so I hope I can help you lowering the size of your applications, reducing costs and saving time while installing dependencies ;)Feel free to criticize, ask questions, come up with improvements :)I also see some cons of my approach:How can someone make sure that I did not alter the original aws-sdk in any way? => Maybe hash folder contents to prove that I did not alter anything?Does everything still work? => Tests are on my agenda. And I am using e.g. modular-aws-sdk-dynamodb in production, so far everything works fine :P

What would subjectively be the name of the directory that you'll place your test files in?

I've seen many projects and libraries on GitHub (and elsewhere) storing test files in a directory named either as 'tests' or 'test', mostly the first one. I've done it for my open-source (and closed-source) projects as well but I prefer 'tests' to denote that there are multiple test files. Though this is purely subjective, this question has always bothered me for which one of the two would sound more appropriate, I guess the plural name 'tests'?

Wrapping my head around Async/Await with node-fetch / axios

TL;DR Every tutorial just has "console.log(res.json())" - not helpful. Has anyone "chained" fetch or axios? The tool I'm writing will be open source but I want to get a head start on it before I'm supposed to be working on it, so I can't really share my code.The github API will list all of my Repos just fine. I can based on that list filter it and return it to only include repos authored by me. I can pass that list into a function to fetch a second request => *the contents of each repo*. Now I'm stuck. From the contents JSON, I need to "store" in memory a list of "files" and a list of "directories", then do operations on the files, and repeat the listing of directories with another fetch, just once more (not recursively beyond that), and do operations on the files in the second level directories.Any help would be greatly appreciated, if there's a request maybe I'll post a 24 hour pastebin.

Introducing Expressive Tea v1.1.0

​https://i.redd.it/8axg4yinlxt31.pngSince 7 months until now my company is working on a express base framework using Typescript as main language which we named Expressive Tea. This using typescript mainly to use the Decorators which allow to write clean and less code. We wanted to do this as a pluggable and modulable framework to allow developers share code between projects, also, we wanted to be neutral so we detoxify our code to not force it to use one type of architecture (named MEAN, MERN, etc), that is because We wanted every developer decide their own flavor.Of course We know sometimes developers want to use a kind of architecture or settings, like someone use MongoDB with Mongoose, or just PostgreSQL, from Angular to React. That is why on the latest version we add a plugin engine that allows share many flavors of Expressive Tea.If anyone wants to give it a try you can get the project information here, also if you want to try the new plugin feature you can take a look here. If you want to know a little bit how this is working you can see the video that we have it (just warning is a little big so don't rush on this) or you can follow the tutorial series on medium here.Thanks for reading and your comments/suggestions.

I'm working on an app that has client side and server side hosted on two seperate heroku deployments. When I hard code the url in the axios call from the front end to the back end it works in the production environment:auth.js file:const baseUrl = 'https://url.herokuapp.com/'function Auth() {    axios.get(baseUrl + 'api/user', test)​But if I add the following to the .env file and change the code as below it doesn't work:auth.js file:const baseUrl = process.env.REACT_APP_SERVER_URL || '/'function Auth() {    axios.get(baseUrl + 'api/user', test).env file:if (process.env.NODE_ENV !== 'production') {    REACT_APP_SERVER_URL = "http://localhost:3001/"} else {    REACT_APP_SERVER_URL = "https://url.herokuapp.com/"}​I've tried adding and installing dotenv to a route server.js file on the front end but now luckrequire('dotenv').config();​Any ideas?

Downloading a zip archive from Express endpoint

Hello, everyoneI have a simple issue, but it's been driving me crazy for the past 2 days. I have an archive.zipfile in my node/express app which I'm trying to send via a response. My code is pretty simple, I have an endpoint /download whos only job is to do response.download("archive.zip")However, upon downloading the file (by accessing the URL through a browser), the .zip archive is downloaded, but the files in the archive are corrupted, and I get the error Unexpected end of archive.The actual file is a good, non-corrupted archive. I can access it on the windows filesystem without any problems. It's just when it gets transferred it gets corrupted.I have tried setting various response headers, among which:Content-Disposition: attachment Content-Type: application/zip, application/content-stream Transfer-Encoding: chunked Nothing has worked up to this point. I have searched far and wide on google / reddit / stackoverflow and haven't come up with a solution so far.Thank you for any or all responses.

NodeJS nested function. How to get value?

Hello together,i am working on my first nodejs project. Currently i struggle on one special syntax from nodejs:I have developing expercience, but never seen such before :DThis special "then" syntax and scoping. For example i have this code:​keyVaultClient.getSecret(vaultUri, "key", "").then(function(response){console.log(response);})​How do i access the variable response from my code outside the function?I have seen a lot of code with such special nested syntax. So how i can handle the scoping?Where i can find information about these syntax and scoping.?​Best greetings

Help needed - Survey on Code Smell Harmfulness

Hi there, I'm a MSc Student on Software Engineering from Brazil. I'm currently studying the Code Smell Harmfulness. I refer to "Smells" as pieces of code that need to be improved. Examples of these code smells are Long Methods (method that is too long and tries to do too much) and God Class (classes that tend to centralize the intelligence of the system). By code smells harmfulness, we mean code smells that can degrade the software quality, e. g., bug-prone code smells.I would like to kindly invite you guys to participate in a survey on this topic. The goal of this survey is to identify the perceptions of professionals regarding the harmfulness of code smells.Answering the survey should take around 3 minutes of your time.Link: https://forms.gle/QzN9nPHj9Peu9ZG17All the data collected from the survey is anonymous. The results of the survey may be reported in academic publications. If you have any questions or concerns, please contact me (Rodrigo Lima) [rsl@ic.ufal.br](mailto:rsl@ic.ufal.br).Thanks, It will be very helpful the answers from you guys,Rodrigo Lima

How do you handle errors in your Repositories/Data Access Layer?

I'm working in TypeScript, and I have a Repository that encapsulates my ORM's query building API. To sign up a user, for instance, a Controller Action delegates to a Service, which calls methods of my Repository.I impose particular constraints with my ORM, such as stating that an email field must be unique. That means that my Repository's save and update methods for the user could throw an error by the ORM. If that's the case, and for the purpose of abstraction, I obviously want to encapsulate that error with some custom error type.So, should my Repository functions intentionally throw domain-specific errors to be caught by the Service? I was considering letting errors bubble up all the way to the Controller, and then handling it with Express Middleware to return a proper response to the client. Another option might be to build an Either Monad result wrapper for my Repository functions and have them return that.Do you have any advice?Thank you.

How do I update the database after a keyup event or at the very least setinterval()?

So I want to implement a sort of drafts feature, like how Gmail will save your written email in drafts before sending it and updates a few seconds every time after typing something. I want to update the database in a drafts table after every few keystrokes but I don't believe you can do jQuery to database as it's front-end, so I'm not sure how email services are able to do that. If that method isn't feasible, can I do a setinterval() around a callback function that updates database?

SSR vs CSR. Template Engine vs API+Frontend separated

Hi guys, i am learning Node.js and i have a question.I want to build a Node.js API (Node+Express+Mongo, with tokens, etc.) and also a React frontend page.The question is, what is better and why?:All in Node with Server Side Rendering (SSR) using a Template Engine (like EJS, Pug..)API with Node.js and website with React (Client Side Rendering CSR) on a Nginx server for sending html+css+js files.I saw that SSR is faster, but the problem is that rendering is a sync process and it means that server will only process about two requests per second (or something like that i read) and if you have a lot if requests at the same time, you have a problem.

Need help with MongoDB database structure

Hey,​I am making a server synced diary application with NodeJS, and using MongoDB. I have all my super relational data in MySQL. But for users Daily memoirs im going to use Mongo, because as you may have realised, there will be a crap load of notes/day diaries, and I want to learn MongoDB, and it is supposed to be way better for lots of non relational data.​I have learned how to create DBs and do everything, but something all the tutorials dont cover, is the most important thing of all, how do I structure my data?​Down below I have several examples of what ive thought, and as I am pretty unexperienced with Mongo, I would like some advice, on which option would be the best performance wise.​Thank you in advance for your time, and any help!​Example 1: My database has one HUGE collection called “Days” and each entry to that collection looks like this: (I am sorry, but no matter how much I think about it, this sounds like the least performant option, as said I am unexperienced in Mongo, and might be wrong.)​{userID: 902, //This user ID will be fetched from MySQL when authenticating users request. From what ive read, I need to run a command similar to this: “db.posts.createIndex( { author_name : 1 } )”, on this collection to somehow optimize performance? //What day? No, I wont use Date for this, because then id have to turn my JSON Query data to Date before querying (Maybe I wouldnt have to, as Mongo may store it as string anyway). BUT, I am not sure whether i should use 3 separate Integer fields, or one string field. Which would be faster? (EDIT: I know three separate fields with int will be WAY faster, as my application also has to query data for one month, etc. MAYBE Im wrong, and this is bad practice, let me know.) day: 12, month: 5, year: 2018, //Actual stored data: dayTitle: “Lame day at home..”, dayDescription: “Installed arch..”, hugeLoadOfIndividualSmallNotesForThisDayWithTimeStamps: [ { data: “Woke up, start now”, time: “9:44”, { data: “Finally figured out what fdisk is”, time: “21:29” } } … ] }​Example 2: My database has a collection for each user which is named by their userID (This sounds VERY good and organized to me, and with my common sense, it would sound like the most performance one, but from what I googled, people said this wouldnt be good, and thats EXACTLY why I am asking here), and each entry to that collection looks like this:​{day: 12, month: 5, year: 2018, dayTitle: “Lame day at home..”, dayDescription: “Installed arch..”, hugeLoadOfIndividualSmallNotesForThisDayWithTimeStamps: [ { data: “Woke up, start now”, time: “9:44”, { data: “Finally figured out what fdisk is”, time: “21:29” } } … ] }​Example 3: My database has a collection for each day. (This is basically same as example 2, but there will be less collections. I am very unsure whether this would be bettter than option 2 performance wise, and also this would KIND of, be harder to implement because days change etc.), and each entry to that collection looks like this:​{userID: 902, dayTitle: “Lame day at home..”, dayDescription: “Installed arch..”, hugeLoadOfIndividualSmallNotesForThisDayWithTimeStamps: [ { data: “Woke up, start now”, time: “9:44”, { data: “Finally figured out what fdisk is”, time: “21:29” } } … ] }​As said before, thanks in advance guys!

Is using 'location.assign' a bad idea for a get request

Using express for reference.Context: Basically I'm rendering a list (via ajax front end) but at this point I'm not using any href's for each list item. Instead if the item is clicked it is grabbing a dataset value. That works and I can send the request from axios to express and get my data back. It's a 'GET' request since I have no form elements in the list.Problem: So the item that is retrieved requires a good amount of html. I think it might be better to just use a pug template on the back end and have express render it (instead of front end rendering). The problem is with the way things are set up (no hrefs) the only way I figured out to make it work is doing a location.assign('/route/id').It works but I have a sneaking suspicion that it maybe a bad practice.tl;dr: Is using location.assign a bad idea for sending a 'GET' request ?

Having trouble hiding button inside my pug file

Hi there, im truly appreciate it if anyone can help me towards my problem or point where my mistake is. Currently I wanted to hide a button inside my pug file if certain condition is met. The condition I set inside my pug file is that if the user.id is equal to the tournament.author, only show the button if its belongs to the user otherwise hide. I created this condition is to not let other user edit or delete the tournament post. Below are some code I provide to help anyone identify what did I missed.​mongodb sample data> db.tournaments.find().pretty() { "_id" : ObjectId("5dab977fcec7714424b1ad0f"), "date" : ISODate("2019-10-19T23:08:47.521Z"), "title" : "Post1", "author" : "5dab7d10b9b5c73de0ed0ea2", <--- should be the same with user.id > db.users.find().pretty() { "_id" : ObjectId("5dab7d10b9b5c73de0ed0ea2"), <---- should be the same with tournament.author "date" : ISODate("2019-10-19T21:16:00.541Z"), app.jsapp.get('*', function(req, res, next){ res.locals.user = req.user || null; next(); }); tournament.js//Show Single Tournament router.get('/:id', function(req, res){ Tournament.findById(req.params.id, function(err, tournament){ User.findById(tournament.author, function(err, user){ res.render('tournament',{ tournament: tournament, author: user.username, }); }); }); }); //Submit To Create Tournament router.post('/create', ensureAuthenticated, function(req, res){ req.checkBody('title', 'Title is required').notEmpty(); req.checkBody('size', 'Size is required').notEmpty(); req.checkBody('type', 'Type is required').notEmpty(); req.checkBody('body','Body is required').notEmpty(); let errors = req.validationErrors(); if(errors){ res.render('create_tournament', { errors: errors, user: req.user, }); } else{ let tournament = new Tournament(); tournament.title = req.body.title; tournament.author = req.user._id; tournament.size = req.body.size; tournament.type = req.body.type; tournament.body = req.body.body; tournament.save(function(err){ if(err){ console.log(err); return; } else{ req.flash('success', 'Tournament created'); res.redirect('/'); } }); } }); //Submit Edited Tournament router.post('/edit/:id', ensureAuthenticated, function(req, res){ let tournament = {}; tournament.title = req.body.title; tournament.author = req.user._id; tournament.body = req.body.body; let query = { _id:req.params.id } Tournament.update(query, tournament, function(err){ if(err){ console.log(err); return; } else{ req.flash('success', 'Tournament updated'); res.redirect('/'); } }); }); tournament.pug (example screenshot).card-body strong Player Slots: |   #{tournament.size} br strong Bracket Format: |   #{tournament.type} p.card-text |!{tournament.body} p.card-text small.text-muted #{tournament.date} by #{author} if user .btn-group.float-right if user.id == tournament.author a.btn.btn-outline-dark.btn-sm(href='/tournament/edit/'+tournament._id) Edit a.btn.btn-outline-dark.btn-sm.delete-tournament(href='#', data-id=tournament._id) Delete

Creating my first "full stack" app. Some questions.

I'll create a simple app. It will be a CRUD (Create, Read, Update and Delete) app that I will use for practicing.It will have a BE: Database + APIAnd a FE: Website and mobile app.For the BE I'm using NodeJS, Express, MongoDB. As explained on this tutorial on Guru99.I'm used to SQL databases. However it seems that MongoDB doesn't use SQL. But that's not a problem, I can learn whatever it uses.The API will have a few endpoints, with GET, POST, PUT, DELETE, etc.For the FE I'll just use JS and probably React and React Native once I'm done with everything and have time to learn React and RN.Do you think I'm well headed? Any advice/tip you might want to share with me?

node-fetch not returning expected message

[Solved]I'm trying to use node-fetch with IFTTT to make a post request. The request works fine and I receive my notification set with the webhook, but there is one thing that is bothering me and I haven't been able to figure out how node-fetch is handling the response.const body = { value1: currentTemperature }; fetch('https://maker.ifttt.com/trigger/temp_reading/with/key/' + key, { method: 'post', body: JSON.stringify(body), headers: { 'Content-Type': 'application/json' }, }) .then(function (res) { //res.json() res.text(); console.log(res); }) .then(function (text) { console.log(text); // returns undefined }) .catch(function (err) { console.log('node-fetch error: ', err) }); Which returnsResponse { size: 0, timeout: 0, [Symbol(Body internals)]: { body: PassThrough { _readableState: [Object], readable: true, domain: null, _events: [Object], _eventsCount: 4, _maxListeners: undefined, _writableState: [Object], writable: false, allowHalfOpen: true, _transformState: [Object] }, disturbed: true, error: null }, [Symbol(Response internals)]: { url: 'https://maker.ifttt.com/trigger/temp_reading/with/key/key-removed', status: 200, statusText: 'OK', headers: Headers { [Symbol(map)]: [Object] }, counter: 0 } } undefined In for example, Postman or CURL, I see the resultCongratulations!
