Write 1 million times
I see there's an example on the documentation for this but I was wondering if there was a faster way? To write a million + times to a filefunction writeOneMillionTimes(writer, data, encoding, callback) { let i = 1000000; write(); function write() { let ok = true; do { i--; if (i === 0) { // last time! writer.write(data, encoding, callback); } else { // see if we should continue, or wait // don't pass the callback, because we're not done yet. ok = writer.write(data, encoding); } } while (i > 0 && ok); if (i > 0) { // had to stop early! // write some more once it drains writer.once('drain', write); } } }

Help needed to decide between MongoDB vs PostgreSQL
Hi, I am trying to decide which DB to choose for my application. I know it is a big decision therefore I will really appreciate your help. Even though I heard PostgreSQL is better than MongoDB in relational data, my tests always gave me faster results with MongoDB. I am trying to understand and decide which database to choose. I setup a github repo at https://ift.tt/2xORBal All methods and tests are same for both MongoDB and PostgreSQL.Following test commands were madeTesting all: npm testTesting MongoDB: npm run test-mongodbTesting PostgreSQL: npm run test-postgreMongoDB version uses Mongoose and PostgreSQL version uses Sequelize.I will appreciate any comments or corrections. Thanks.

How to check from frontend if registration was successful in node backend
Hello, I want to check, if user was succesfully registered in node-expess-mongodb. When username is already in db, "status" is changed to false to stop registration and req.session.registrationStatus is set to false, to send info to front end with POST route. If username is unique, user is registered.I have problem, that although it is sort of working, status from req.session.registrationStatus is one step behind real registrationStatus. So registrationStatus is true (but only after second POST connection with db), but I cannnot see where is error. Thank youBackend:// Route to register user app.post("/register", (req, res, next) => { let username = req.body.content.username; let password = req.body.content.password; let status = true; //status to check if user is already registered db.collection("users") .find() .toArray(function(err, result) { for (let i = 0; i < result.length; i++) { if (result[i].username === username) { console.log("User already registered"); status = false; req.session.registrationStatus = false; //this info is send to frontend req.session.save(); return status = false; } } if (status === true) { bcrypt.hash(password, 10).then(function(hashedPassword) { db.collection("users").insertOne( { username: username, password: hashedPassword }, (err, result) => { if (err) return console.log(err); console.log("saved"); req.session.registrationStatus = true; //this let frontend notify that user was registered req.session.save(); } ); }); } }); }); // Route to check registration app.get("/register/check", (req, res) => { res.send({ registrationStatus: req.session.registrationStatus }); req.session.registrationStatus = false; //registrationStatus is reset to default false value after sending info to frontend req.session.save(); }); Frontend: handleSubmit(event) { post("/register", {username: this.state.username, password: this.state.password}) setTimeout(this.checkRegistration(), 600) event.preventDefault(); } checkRegistration() { const url = "http://localhost:3000/register/check"; fetch(url, { method: "GET", credentials: "include" }) .then(response => response.json()) .then(status => (status.registrationStatus) ? this.setState({ status: "registered." }) : this.setState({ status: "try again." }) ); } Even if user was registered, first response from node is "false" although it should be true.

How do you structure your project by components if you are using mongoose as your orm?
I was browsing through the node best practices guide, and came across this issue. In all of my projects, I have had my models tightly couple to mongoose. It says there that"The major principle should be keeping your DAL as a data-mapper that maps domain entities into DB and NOT owning the canonical application entities. In other words, you have the domain models, simple JS objects that are agnostic to any DB concerns, which are the heart of the system - the DAL is responsible to serialize this model into DB. If you use ORM than that DAL will use its own internal models for the mapping. "I am a moderate expressjs developer and I am not sure how to do this using mongoose. Could someone help, if possible using code samples? Thanks in advance!

newbie question: issue with using "this" within promise
Hey guys,Sorry for the newbie question. This question will definitely expose my lack of understanding of javascript classes.So I'm trying to write a class with methods that return a promise. It seems that within the promise function, the "this" operator no longer refers to the class but is undefined.Here is a useless class that demonstrates what I am talking about:class foo { constructor(data) { this.bar = data; } set(data) { return new Promise(function(fulfill, reject) { this.bar = data; fulfill(); }); } }So obviously this is a fake example but "this" in foo.set no longer refers to foo when in the promiseThanks!!

newbie question about nodejs classes and promises
Hey guys!Really sorry for this newbie question about nodejs. I've started looking into how classes are done in nodejs and I had a question.Are there some general guidelines for when to use or not use promises in a class? For example, would it be bad practice for a class method to return a promise? I was looking around at example code for classes in nodejs and it doesn't seem that this is something people do.For example, is there anything wrong with this:class User {constructor(name) { this.name = name; }do_a_promise() { return new Promise(function(fulfill, reject) { console.log("hello world"); fulfill(); }); }This is just a dumb example but is there any reason that you would definitely not want a method to return a promise?edit: sorry for the formatting. I couldn't get the formatting to look quite right.

Hello r/node,I've been node programmer for a little over a year now and want to make a course on it. What do you think what are some essential topics to put in it. I was thinking of something like introducing JavaScript, installing node, making a console app, making server in pure node, making server in express, deploying it, go over basics of git and Docker, and deployment. Maybe put some testing in it. Of course by making server I would go over HTTP, HTTPS,static content, template engines, clusters, sessions, cookies, databases, authentication, authorization and working with third party API's.

Is it just me or is file storage a major bottleneck for small projects?
Specifically, deploying on Heroku and other 1-button-setup services which have ephemeral storage. As a dev who wants to focus on dev and not ops but wants to deploy some small projects for portfolio and other small use cases.Fair enough, this teaches you the hard way that file storage and the server should not go together. And it feels like at this point you truly are near the end of mastering node/express, and this is probably one of the last nitty-gritty gotchas that's gonna come up.So, then you look at your options. The only real ones are AWS S3, which forces you to drag the, frankly, criminally disorganized AWS API and documentation into your project or... Cloudinary, the website where advertisements take 50% of the screen and it tries to recruit you into it's referral program upon signup.Anyways, is there some go-to service I am missing here that the veterans know about? The Heroku of file storage services? I like that Cloudinary can grab the req.file.path straight off multer without having to save anything to my server and I like how clean and short the module's method is (actually much cleaner than multer itself) BUT... the way the website looks just throws me off. Doesn't seem trustworthy.Thoughts? Ideas?

Could a node program be compiled to a C library?
npm nexe can compile a node.js program down to a single (node-independent) executable file, for any target architecture you want (within reason).I'm wondering if it's possible to make something similar, but instead of packaging a program into an executable file, package it into a shared library or DLL, such that a C client can call arbitrary functions that are exported from the node program (not just the main command-line entry point). (Obviously there would be a good amount of glue, marshaling parameters and return values and whatnot, but that could be abstracted away with a nice library.)If this were possible, it would allow us to create language bindings for node libraries.Does anyone understand how nexe works? And/or how possible/practical this idea is?

Node Performance Benchmarks - CPU Upgrade For Data Processing?
Hey Everyone, I'm primarily developing a data-processing heavy nodejs app on my late 2013 macbook pro (2.4 Ghz core i5 haswell 4258U).The problem is that my data set is doing calculations and a lot of regex on hundreds of thousands of items and it's taking FOREVER with my CPU at 99% for node. I know javascript is probably not the most efficient data processing language, but it's what I know. Have already refactored a few times to ensure I'm not running excess operations.Big question is, will I notice a large difference if I setup an Ubuntu workstation running an AMD Ryzen 8 core CPU? Like enough that I'm not waiting hours for this data set to finish, and I can me more productive?I tried running this in Google Cloud Functions and got hit with a $100 bill after only ~20 minutes of testing the data workflow, but it was FAST lol.

Building Node.js Applications inside Docker Containers on Top of Kubernetes
Docker and Kubernetes are great for deploying and running applications but they do not support the development workflow very well. Mounting a project from a local folder into a container, for example, often leads to problems with hot reloading tools like nodemon and make debugging a lot harder. And coding directly on top of Kubernetes is not supported at all at the moment.That's why a colleague from work and I built a small command-line tool that lets you create a remote workspace called DevSpace inside any Kubernetes cluster with just a single command. This DevSpace is connected to your local machine via 2-way code sync (optimized for performance and reliability), port forwarding and terminal proxy. That allows anyone to code and debug locally with their favorite IDE but still build, test and run code directly inside Docker containers running on top of Kubernetes.We decided to make our tool open source, so that everyone can use it: https://github.com/covexo/devspaceWhat do you think about the idea of coding directly inside a Kubernetes cluster? What are your experiences with developing nodejs applications with/for Docker and Kubernetes? Which tools are you using?

Why these are no quality check on the node modules?
I was actually planning on writing a node module myself and when I was benchmarking it I realised that It is not very fast and eventually will slow down the application of who ever uses it. I came across a couple of modules myself which are not very optimized. I am not ranting and sorry If i sound like, I had this question so thought of putting it across and see what others feel and can we come up with a way where we can help each other write or validate there modules for performance issues.

Node.js native modules with Swift
Hi there. Has anyone had any experience developing node.js bindings for Swift libraries? There are lots of examples out there for creating bindings for C++ libraries. I feel like Swift should work, but I can't find any documentation or posts out there that suggest this would work. I'm not 100% sure where to get started with this.The closest thing I could find was this: https://ift.tt/2NKeXYJ

I am creating an app using an API that provides some configuration settings as a json object that I can pull using Request. however, i would like to store this into a var config object in my index.js so I may pass it into any modules that may need the config info, much like the mongoose that i pass around my app.I have only been so far able to use the information in callbacks and a .then callback on a Promise.

It won't give me an error but gives me a request timeout error on my heroku logs. It just stays in the logging in with google page and won't budge to the callback URL as if the route is not being handled - but it is, it works on Localhost.Oauth is a headache.. .Does anyone have any idea of what is happening?

My end goal is to be a NodeJS back end developer.(Thanks for the early responses, I guess I can honestly say I'm a "Professional" Node Developer. Do NodeJS tasks at work already, but they're completely based on my judgement as I'm the only "Developer" at work. I use the quotes because my title isn't Developer, it's database coordinator.....)Edit: added detail to the question

[Help] Making a script that downloads a file in chunks
Hi All!I was wondering if any of you had a better idea on how to proceed with making multiple axios calls to download all chunks of a file, this is what I have so far.const file = require('file-system'); const fs = require('fs'); const axios = require('axios'); const file_url = 'https://ift.tt/1srKqxy' axios.get( file_url, { // params: { // ID: 12345 // }, headers: { Range: 'bytes=0-1' } }) .then((response) => { console.log('server status: ', response.status); console.log('server response: ', response.headers); fs.mkdir('downloads/', function(err) {}); fs.writeFile('downloads/example.zip', 'aaa', function(err) {}) // FileDownload(response.data); // console.log(response); // console.log(response.data); }) .catch(function (error) { console.log(error); }); My issue is:I need to make multiple axios requests, but not entirely sure how to make enough requests to download the entire file in chunks.I don't exactly understand how header-range works. Whenever I adjust it to '0-1', it still downloads all 3 bytes of the file, which is the size of the entire file.once I download the entire file in chunks do I need to do it with async await so I can stitch it back together or will it save the chunks on my drive and ill have to run it through my script to stitch it together?all help is appreciated. thank you!

Cogear.JS — modern static website generator (Node.JS/Webpack)
Cogear.JS is a static websites generator built with Node.JS (9.x or higher) and based on Webpack (v4.6).It's inspired by Jekyll and others, but built on the top of the latest frontend technologies.Provides awesome hot reloading experience in development mode.https://ift.tt/2ONnxSR video on YouTubeFeatures🖥 Modern stack of technologiesBuild modern static websites with bundled scripts and styles.Rapidly prototype and instantly deploy to the server.Use any modern frontend stack (webpack bundled) – Vue.JS, React, Angular, Ember, etc.🚀 Blazing fast and reliablePerforms nearly 1.000 pages per second (depends on the pages content and raw computer processor power).Server can handle thousands requests per second to serve static files (even on tiny VPS).📦 For any hostingDoesn't requires any database (data stored in flat files) and works with any hosting (as it produces static html and assets files).🚚 Deploy built inCreate a preset and update your site to the server via FTP, SFTP or even rsync.🔓 Secure. No updates neededJust forget about annoying regular updates from usual CMS.It's 100% secure for hacking because there is no backend after being deployed to the server.🌏Free. Open SourcedUse it for free. For any needs. Forever.Github Pages (or any similar project) you can host generated site for free.What it can be used for:Rapid site prototypingPortfolio siteCompany siteProduct sitePersonal blogArtist or musician siteAny site that has admin-generated content.Multi-user content management can be provided via Github. Just store your source in the repository, accept pull-requests from other users and build a site after commits (can be automated).Using Firebase or any other backend, written in any lang (PHP, Ruby, Python, Node.JS) or even with CMS like a WordPress, with help of modern frontend technologies like Vue.JS or React, it can be turned into more dynamic site like e-commerce, products catalog and so on.What it cannot be used for:ForumSocial networkChatOr any other site type with great amount of user-generated content which relies on heavily database usage and dynamically generated pages.Of course you can try, but it has to be modern SPA which handles data from dedicated API.RequirementsYou have Node.JS (9.x or higher) and NPM (usually comes together) to be installed.Download and install.The latest version (v10.9.0) is recommended.You can also use Yarn instead of NPM.Cogear.JS runs on:MacLinuxWindowsYou may want to use awesome VSCode editor.InstallationInstallation video on YouTubeUsageGo to the directory where all your local sites are hosted.$ cd ~/Sites Create a new site via command:$ cogear new site.io # where "site" is your site folder name How to create a new site?After that go to site directory:$ cd ~/Sites/site.io And start up Cogear.JS in development or production mode (learn more).$ cogear # run in development mode with hot-reload – by default $ cogear production # build a site and run local server Next time we will dive deeply into the workflow.Github repository: https://ift.tt/2zxcWGD site: https://ift.tt/2ONnztX https://ift.tt/2zxcHeH

A lost traveler trying to find his way through this realm (Node.js, EJS, Apache, A2 Hosting)
Greetings all,Preface: I tried to post this in /r/webdev first but due to my low karma it got flagged and the mod hasn't approved my post yet so for now I will reach out here because I've already talked to some awesome people in this community who were very helpful before. So without further ado, welcome to my problems!I'm having some issues hosting a Node.js application on a shared/managed server that's hosted by A2 Hosting, which of course means I do not have root access on it (yes, I know I should be using a VPS but unfortunately I can't due to work restrictions). I figured I would post a little about it here just in case anyone can spot something I'm not seeing or maybe just point me in the right direction. I feel like I'm surprisingly close to having this thing actually work under these constraints and I'm super excited but it's also driving me insane. Any and all comments would be greatly appreciated!First, a little about the server itself - as I mentioned before it is a shared/managed linux server that is hosted by A2 Hosting and is running CentOS 6.x. The application structure and surrounding file system looks like this...(The ~/ represents the true linux /home/$user/ directory, not the web server root.) ~/ ├── public_html (Apache web server root directory) │ └── .htaccess └── myapp_repo (My Node.js app) └── myapp ├── app.js ├── bin │ └── www ├── node_modules │ └── * ├── package-lock.json ├── package.json ├── public │ ├── images │ │ └── img.png │ ├── javascripts │ │ ├── init.js │ │ └── menu.js │ ├── materialize │ │ ├── css │ │ │ ├── materialize.css │ │ │ └── materialize.min.css │ │ └── js │ │ ├── materialize.js │ │ └── materialize.min.js │ └── stylesheets │ └── style.css ├── routes │ ├── about.js │ ├── contact.js │ ├── index.js │ ├── send.js │ └── services.js └── views ├── about.ejs ├── contact.ejs ├── error.ejs ├── index.ejs ├── partials │ ├── banner.ejs │ ├── foot.ejs │ ├── head.ejs │ ├── menu.ejs │ └── script.ejs └── services.ejs I was able to install node and npm just fine and also configured my application to run on port 49157 because...To run a Node.js application on a managed server, you must select an unused port between 49152 and 65535 (inclusive). ^ directly from their docs.The next step that I took was figuring out how to re-route all web traffic to my node app instead of the apache root (i.e "~/public_html/"). I did that by writing a rather simple .htaccess file that routes everything to my loopback address at the port that I configured my app to listen on. It looks like this...$ cat ~/public_html/.htaccess RewriteEngine On RewriteRule ^.*$ http://127.0.0.1:49157/ [P,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d To my surprise after starting my application using $ nohup npm start --production &it was actually somewhat working when I visited my domain in my web browser. From what I can tell it seems like the HTML from my index.ejs file is rendering correctly but all the CSS and JavaScript is not (I linked bootstrap via their web link, hence the visible text styling). It looks like this...Obviously I immediately checked out those JS files and there is nothing wrong with them. I'm not really sure why I'm receiving those errors. Maybe one of my templates is inserting an extra character when it renders? I of course do not get this error when running it locally.Obviously I immediately checked out those JS files and there is nothing wrong with them. I'm not really sure why I'm receiving those errors. Maybe one of my templates is inserting an extra character when it renders? I of course do not get this error when running it locally.At first I thought it would be an easy fix, probably just the file paths had gotten a little offset from how I was running it locally on my dev machine but after trying every possible relative path and also absolute paths all the way from the root directory of the machine itself, nothing worked.Like I said before, this is driving me insane because I feel so close yet so far from getting this working correctly. I'm still new to building with node and also on the web in general so please pardon my stupidity in any and everything I have said or may say! I still feel like it's most likely a file path issue but I just can't seem to spot it. Again, any and all comments or suggestions would be super! Thanks for reading this and please feel free to comment and yell at me for being dumb because honestly... you're not wrong!

I am a beginner nodejs developer, working on developing an express rest api with optional query params.For example consider the following schema for a user:phone: {countryCode: String,number: phoneType},phoneVerified: { type: Boolean, default: false },emailVerified: { type: Boolean, default: false },rating: Number,balance: { type: Number, default: 0 },occupation: String,gender: { type: String, enum: genders },I want to expose this resource at /users and allow querying through optional query strings.For ex, /users?emailVerified=true&phoneverified=false&gender=male&occupation=plumber&limit=10This should return all the users which satisfy the criteria, while keeping almost all of the options optional.What is the best way to do this in a maintenable and futureproof way?Appraoch 1: My first approach was to use if blocks to check which parameters exist in the query and build mongoose queries accordingly, but that looks ugly and very hard to read.queryObj = {};if (req.query.params.occupation) {queryObject = {...queryObject,occupation: req.params.occuption};}if (req.params.phoneVerified) {queryObject = {...queryObject,phoneVerified: req.params.phoneVerifed};}const users = await User.find(queryObject);I also found the querymen package which looks promising. If someone experinced could guide me as to what is the best practice? Thanks in advance

Mongoose error handling
I really like mogoose schema and how it validates the data but I don't know If I'm the only one who think that the hardest task when you are working with mongoose it's error handling and it's even harder when you are developing an api for third parties and you have to forward those error in the prettiest and understandable way to them. So, I want to know how you guys handle mongoose errors?

Getting confused designing REST API that has Users
I have an auth router and an api router for my Koa app.The auth router looks something like:const router = new Router({ prefix: '/auth' }) router.post('/signup', async ctx => { ... }) router.post('/login', authenticate(), async ctx => { ... }) router.post('/logout', async ctx => { ... }) and the api router looks something like:const router = new Router({ prefix: '/api' }) // Get user by ID router.get('/users/:userId', async ctx => { ... }) // Create a user router.post('/users', async ctx => { ... }) // Delete a user router.delete('/users/:userId', async ctx => { ... }) // Get food by ID router.get('/foods/:foodId', async ctx => { ... }) ... The main question I have is about the users part of it (not the food stuff). I am noticing that both the POST /users and the POST /signup do the same thing (essentially call myDB.createUser()). I am wondering if I shouldn't have a POST /users in my API at all. I just felt weird not having it because the food stuff and other API routes are probably going to have POST, GET, DELETE, and PUT methods in each of them.TLDR: Should I only have 1 create user route (instead of 2), or should I somehow be calling POST /users in my POST /signup route.I do have one other small question – should I be desigining my API to be like GET /users/:userId or GET /users:/username or somehow allow both?

having trouble using MSSQL with node and express
I am coming from a "mongo/mongoose .then .catch" background. Now I need to learn mssql with node/express. Surprisingly, I am having trouble finding documentation on how to GET/POST/PUT/DELETE using mssql commands (instead of mongo/mongoose).Quite a few tutorials out there show "proof of concept", as far as how to set up node/express, a sql db on azure, and return a random table from the classic adventureworks db , in console.log upon successful db connection. I get that.But I'm having trouble finding out how to configure my API to send GET/POST/PUT/DELETE commands to my sql server using express routing like server.get, router.post, etc.I know I must have the wrong approach because of my lack of search results. Can anyone point me in the right direction?Thanks!

Embeddable file based object databases for NodeJS
I have been using nedb for a while on my projects but it being not maintained for about 3 years now, I decided to switch to some other such database. Modules like levelup are out because it doesn't provide query operations like lte, gte ...etcI found a few solutions like nedb-core (looks like unmaintained) tingodb, tedb ...etcI am unsure about which module to go with. Both tingo and tedb looks like they suit my need. Which one would be the better option out of the two? And if there are other options, please let me know about those too. Or is NeDB still relevant that I can keep on using it?

Authenticating my app with another service using OAuth 2
Looking for some help to point me in the right direction, I've searched for tutorials/guides on this but it all seems to be about creating the authentication on my side rather than authenticating my app with another API service.Scenario: I'm creating a SlackBot to hook up with another API service. This service uses OAuth 2.0 to authenticate. I need to make REST API requests from my Node.js app to the API service, authenticate with an OAuth token, retrieve the data, manipulate it and then send it to the SlackBot to post in a channel.I'm fine with working with the API and getting data into Slack, I'm looking for assistance with how to properly get and store OAuth tokens inside my app for use. Does anyone know of any guides on this topic?

Separation of concerns with MERN?
So I'm working on trying to teach myself how to not suck with the MERN stack. Already have a lot of good experience with React, trying to get a good handle on the back end. I've made a couple of apps that work great, but the code looks like garbage since there's a thousand different things going on at once in the same file.I'm used to separating out files with React so everything has one or two jobs and that's it - makes it easy to read and manage if stuff needs to change. So, along a similar vein, is there a general practice for separation of concerns with Express / MongoDB handling / etc, or is it more of a 'however the project requirements shape it' kind of thing?As an example - currently in this project I'm using Express, Mongoose, Body-Parser, and Passport. Is there a particular way that I should be handling these libraries in order to separate everything out appropriately? Everything is in one file (minus Routes) and works like a charm but it's also, to put it bluntly, an unreadable clusterfuck, so I'm trying to do this right. If there's any advice, thoughts, or resources that anybody thinks would help, I'd greatly appreciate it. Alternatively if there's any must-read books or must-watch lessons on this, I'm down for it. Thanks!

When it comes to deployment, I create a production build of angular and deploy it on a tomcat server exposing index.html file..this build has js code which will call spring apis in my backend once it lands in user's browser..In past instead of spirng, I have used node as backend and written business apis using express js..But, Where and how one uses node as a front end and how would it talk to backend?

Help me fix my "Node Dev to Deployment" app
I'm a fucking noob. So, I recently finished Brad Traversy's "Node Dev to Deployment". What I built sorta works but it's got major issues. I'm hoping some good samaritan can clone this code, run it, identify my fuckups, and advise me on how to fix them.In the navbar partial, I'm unable to conditionally display the "Login/Register" and "Logout" links depending on whether the user is logged in or not. It seems I may not be able to successfully extract the user object and pass it to the template. I don't know.In controllers/ideas.js, I'm protecting the routes with the "checkIfAuthenticated" function, but for some reason, this results in login loops, causing redirects to the login page even after seemingly successful logins. I don't get it.Not sure if the delete route for an idea is properly configured to allow only the creator of that Idea to delete it.There are probably other issues, but the above were the major ones I identified and couldn't fix.

How does your company use Node.js? (I'll show you mine if you show me yours)
Hi, long time lurker here. I personally find it difficult to get a read on patterns businesses use for node.js. Obviously it's easy to find patterns that are common throughout open source projects, but these are mostly frameworks rather than large applications intended to be hosted and run somewhereSo, let's compare notes! I'm going to give a short summary of the technical domain of the company I work for, how many employees and then an overview of patterns we use within the code and if I'm lucky some of you will too :)What we doThe company I work for is basically a big ETL pipeline, pulling in data from various sources. Data is filtered, transformed and finally aggregated into a search engineWe're a startup and so only have 3 developers including me. We've been working on our technology for 3 years. In our first 2 years, we played about with Python, Node.js and Clojure. About a year ago we decided to settle on Node.js. The three of us are relatively new to Node.js but have picked up the basicsHow we doProject structureThese files are just made up of course but show the general structure- src/ - todos/ # some of our projects are monoliths and some are (micro?)services. Monolith projects have separate components in different folders and code is kept separate to reduce monolith complexity - route/ - postTodoRoute.js # Express route - getTodosRoute.js - worker/ - removeObsoleteTodosWorker.js # job that runs on a schedule. Generally just setInterval. Now that node.js has workers, this is a bad name 🐶 - service/ # all code that talks to external dependencies. Useful to keep them separate by convention so it's clear what needs to be stubbed in integration tests - postgres/ - getTodosService.js - datadog/ - auth0/ - transform/ - pgTodoTransform.js # transform a Todo from postgres representation to in-memory - models/ - todoModel.js # though our code is not object-oriented, we still represent common data structures in `class`es as they work well with JSDoc and editors tend to be able to autocomplete fields - dependencies.js # an object that contains all side-effect dependencies. This can be stubbed in integration tests and is passed to routes as req.dependencies and passed to workers as a function arg - utils/ # other stuff - router.js # express router for routes exposed by this component - index.js # set-up workers and any other initialisation logic for this component - someOtherComponent/ - test/ - todos/ - integration/ - unit/ Coding styleOur code is sort of procedural, sort of functional. By this I mean that we very rarely mutate state and that code that has external side-effects is confined to services/ folderI'll give some contrived examples:src/todos/route/getTodosRoute.js:async function getTodosRoute(req, res, next) { try { logger.info('todos/routes/getTodosRoute() - starting..', { 'req.query': req.query }); const result = Joi.validate(req.query, GetTodosRequestQuerySchema); if (result.error !== null) { throw result.error; } const pgTodos = await req.dependencies.getTodosService(req.query); const transformedTodos = pgTodos.map(pgTodoTransform); const response = { todos: transformedTodos, }; logger.info('todos/routes/getTodosRoute() - finished'); return res.json(response); } catch (error) { logger.error('todos/routes/getTodosRoute() - error', { error }); return next(error); } } module.exports = getTodosRoute; src/todos/worker/removeObsoleteTodosWorker.js:function create(dependencies, frequencyInSeconds=60) { // again, a worker is not a Node.js Worker. We just foolishly named these workers const worker = new RemoveObsoleteTodosWorker({ depencencies, eventEmitter: new EventEmitter(), intervalId: null, state: {}, }); worker.eventEmitter.on('start', () => { worker.intervalId = setInterval(async () => { try { logger.info('todos/workers/removeObsoleteTodosWorker/create() - starting iteration..'); worker.state = await onIteration(worker); worker.eventEmitter.emit('iterated'); // used by integration tests to inform when worker has iterated logger.info('todos/workers/removeObsoleteTodosWorker/create() - finished iteration'); } catch (error) { logger.error('todos/workers/removeObsoleteTodosWorker/create() - error during iteration', { error }); worker.eventEmitter.emit('error', error); } }, frequencyInSeconds * 1000); }); return worker; } function start(worker) { worker.eventEmitter.emit('start'); } module.exports = { create, start, }; A word on componentsSome of our components are separate microservices and some are simply modular bits of code within a monolith. Right now these only ever talk to each other via REST interface or by setting state in an integration database. We're looking into more robust and asynchronous communication soon like RabbitMQ or SQSWould be VERY interested to hear how other companies deal with inter-component communication :)Commonly used frameworks / librariesexpressmocha/chai/sinoneslintlodashjoi (https://ift.tt/2PXsXuJ Schema validationmoment-timezone (https://ift.tt/2O7S6Wi Datetime / timezone stuffdotenv (https://ift.tt/2PXsYyN Loads env vars for local development.

In the node apps you’ve written or contributed to, how much business logic is located in the app layer (by means of an ORM etc.) versus in your database as functions/procedures (for those using postgres/rdbms etc)?
Torn on architectural approach. I.e. try to keep everything high-level via sequelize, possibly support multiple databases, versus going straight to postgres functions (with rich triggers for updating creation/modified times, and more).The software is a CMS designed to be used by multiple users standalone, as opposed to a SaaS offering that is largely hosted/managed by one user/company. One day it will probably be extensible (users can add components without modifying core). Is there more flexibility in handling most business logic in the app layer in this case?

I've seen this used in the booting phase of a node.js application, but I've never seen it used at runtime.

Best way to implement a transaction queue in my Node app?
Basically, currently I have a REST API on Node+Express that takes about ~40 seconds (or more) to process the request (encode and store some data) and return a response (receipt).But a 40-second response tine is not very nice, and I want to implement a system that allows me to return a promise or an ID of the transaction instantly whenever it is requested, and put the said transaction into a queue for it to be processed so that the API caller doesn't have to wait almost a minute or sometimes even more to get a response, and instead get something that is able to look up if the transaction has succeeded later.Ideally this should be able to handle simultaneous/very consecutive calls too, as long as I can return some response to check the results later. Transaction processing time doesn't matter, as long as it is in the queue and it is going to be executed.Thanks in advance!

Best way to append to a file on every request in a Node app?
I am working on a Node app that uses Express to handle requests. I have a file I want to append a line to for each request, and eventually this file gets sent off to do some batch processing. Yes, kind of like a log file.I don't have a great grasp of how exactly Node handles each request. If I simply call appendFile in the express route handler, will that cause the file to get corrupted? I assume I don't want to do appendFileSync because then the request handler will block, right?

Node noob in need of help due to an issue that most likely is just his lack of knowledge.
Greetings All,I'm sorry if this is the wrong place to post this, I'm relatively new to this. I've been an observer on reddit for years but this is my first time ever reaching out.I'm having some difficulties getting a website I built with node.js up and running and I'm posting this here to see if anyone can spot something I'm not seeing or maybe just point me in the right direction. Any and all comments are greatly appreciated!So I'm host a site I built with node on an A2 managed server (work constraints, trust me I know smh). It's a CentOS 6.X box. I got node and npm installed just fine and also configured my application to run on port 49157 because...To run a Node.js application on a managed server, you must select an unused port between 49152 and 65535 (inclusive). ^ directly from their docs.I got my application directory all setup, "~/myapp_repo/myapp" to keep it simple. I'm just trying to deploy the default express page right now to test things out. I've setup the .htaccess file in the "~/public_html" directory to forward all web traffic to port 49157. When I try to access the site via my web browser I am presented with the default a2 hosting page but when I curl the site at port 49157, I get the page I'm hoping for!$ curl http://mysite.com:49157

I'm still new to building with node and on the web in general so please pardon my stupidity in any and everything I have said or may say!My best guess is that I'm doing something wrong within my .htaccess config so here's that$ cat ~/public_html/.htaccess RewriteEngine On RewriteRule ^$ http://127.0.0.1:49157/ [P,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ https://ift.tt/2I59iqb [P,L] Again, any and all comments or suggestions would be super!

ws library is not sending or receiving messages.
So I am creating a simple WebSocket server that takes messages sent by one client and broadcasts it to all clients. The code is below.const WebSocket = require("ws"); const ws = new WebSocket.Server({port: 8081}); ws.on("message", message => { console.log("message"); ws.send(message);}); setInterval(()=>{ws.send("test");}, 1000); All clients connect successfully. However, when I send a message, the function in ws.on("message") does not get called. "message" does not appear in my terminal. The last line was added just to test sending, but when ws.send("test") gets called, I get TypeError: ws.send is not a function. The API docs for ws tell me that this will work, so what is going on here?

node.js + express + serialport, command from a POST does not get written to serialport
I wanna control an Arduino via webinterface which is hosted by an node.js server. The idea is, that I send (POST) a command (String) to the server, which forwards the command via 'serialport' to the Arduino. I use 'express' for the website, so my folder structure is something like. ├── app.js ├── bin │ └── www ├── package.json ├── routes │ └── index.js └── views └── index.pug The website works great and I can make a POST to send a command to the server.Now I wanna forward this command via 'serialport' to the Arduino. So I have in /routes/index.js this:router.post('/', function (req, res, next) { console.log(req.body.command); mySerial.write('I am sending a command!', function(err) { if (err) { return console.log('Error on write: ', err.message); } console.log('message written'); }); }); This cause an error: ReferenceError: mySerial is not definedOk, I think I get why: It's bc the code below about 'serialport' is located in /app.js . If I put mySerial.write() here in this section, node.js will send a String to the Arduino, but here I can't handle the command from the POST. I can't figure out myself what I have to do, to make it possible, that the command from POST is forwarded to the serialport.I am looking for a solution which makes it possible in the future to send a status from Arduino to the Browser.const SerialPort = require('serialport'); const Readline = SerialPort.parsers.Readline; const parser = new Readline(); const mySerial = new SerialPort('COM3', { baudRate: 115200 }); mySerial.on('open', function () { console.log('Opened Serial Port'); }); mySerial.on('data', function (data) { console.log(data.toString()); }); mySerial.on('err', function () { console.log(err.message); }); Thank you!Greetings

Is there no best practice way to install Node?
Okay, let me preface with a bit of backstory. (I'm running mac OS High Sierra)Back a month or two ago, I decided to install npm and node with Homebrew. That's right, I installed a package manager with a package manager. I had no idea the headache this would cause.I uninstalled my Node and NPM versions that I had downloaded from the official disk image on the Node.js website (following these steps https://ift.tt/2PSpP3q), installed them both via brew, and was happily on my way.Well, I knew very little about running globally installed NPM packages on a Node binary installed by Homebrew. I ran sass to compile some stupid web project CSS I was working on and ended up literally crashing my computer. I almost had to reformat my disk and reinstall mac OS.So, I went ahead and somehow fixed everything, realized the philosophical problems behind installing NPM with Homebrew, and stuck my official Node.js disk image installation. I've never had any symlink issues since.Fast forward to now.I am trying to now install nasm via Homebrew, and I'm honestly terrified to move forward.I ran brew doctor and have about 200 or so unlinked header files all contained in /usr/local/include/node/*/Brew is prompting me to either 1. run brew install node (no thanks) 2. run brew pruneIs brew prune going to break anything?The output of my current which node and which npm is /usr/local/bin/node and /usr/local/bin/npmI don't want these unused Node headers just sitting there, it feels dangerous. If anyone has any recommendations, that would be much appreciated.Also, I'm planning on getting a new computer soon (a newer Macbook Pro). Is there a "best practice" to install node? Maybe install nvm via homebrew and then install node through nvm? I'm doubting myself because I read the first answer to this SO post: https://ift.tt/2xs7YcO help is greatly appreciated!

I am probably creating too much confusion with Mongoose Schema so I'd be happy to find some suggestion.I have 3 Schema for:- Company- Position- CandidateThese are the working cross-references amongst them (using mongoose.Schema.Types.ObjectId):- each Company has a property that includes the array of open positions for that companyname: String, logUrl: String, positions: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Position' }] - each Position has a reference to its own companyrole: String, salary: Number, jobDescription: String, company: { type: mongoose.Schema.Types.ObjectId, ref: 'Company' } - each Position has also an array of candidates that applied... candidates: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Candidate' }] - each Candidate has an array of positions (a single candidate can apply to multiple positions).name: String, surname: String, email: String, positions: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Position' }] Using .populate( ) I am able to manage all of them and access specific properties of linked objects. In this example, I can open the profile of a candidate, read the list of positions he applied and display the logo of the companies that have those openings. In this other example, I can open the profile of a company, read the list of openings and see the number of candidates for each one of them.So far so good, everything works as expected ✌️Now my goal is to add two properties to the array of positions in the Candidate schema than can keep track of the status of that application and the notes taken by the HR manager: the output should be similar to this.My Candidate schema is now:name: String, surname: String, email: String, positions: [ { detail: { type: mongoose.Schema.Types.ObjectId, ref: 'Position' }, progress: { type: String }, // keep track of the status comment: { type: String } // keep track of internal notes }], My code for opening and populating the candidate's page is:app.get('/:id', (req, res) => { Candidate .findById(req.params.id) .populate({ path: 'positions.detail', model: Position, populate: { path: 'company', model: Company } }) .exec(function (err, foundCandidate) { if (err) { console.log(err) } else { res.render('candidates/show', {candidate: foundCandidate}) } }) }) Now the problem: positions.detail is not getting populated. With the previous Schema (and without these two new properties), I was able to easily retrieve data on the position with position.property as well as on the company with position.company.property; now I am using position.detail.property and position.detail.company.property but they don't work: Cannot read property 'property' of undefinedCan anyone help me with this?

Why Node.js is Preferable for Web App Development
There are several reasons to prove node.js 's candidacy but some of are as Below:why nodejs for web app backend-- Node.js can increase any framework’s speed. [Developers need to do is write the program correctly and Node.js applications will adhere to the steps prescribed.]-- encourages sharing with the presence of the NPM, developer can reuse codes with utmost ease [Therefore, it can be stated that Node.js package manager is robust and a consistent solution for developers.]-- Data streaming in Node.js is like work with data uploading in real time. [The fact that data streaming wins with Node.js can actually be leveraged by developers to take extraordinary advantage when creating features like – processing files while they are being uploaded.]-- Node.js can be used as proxy server if an enterprise lacks its professional proxy infrastructure.-- easy to send and synchronise the data between these two points [helping developers to save time.]So instead of thinking for one time, better to think for long term and work according to it.

How can I handle randomized selectors?
I'm trying to post things to Facebook automatically via Puppeteer.The selector I'm trying to click is:#u_0_2e > div._sa_._gsd._fgm._5vsi._192z._1sz4._1i6z > div > div > div > div._3399._a7s._20h6._610i._610j._125r._2h27.clearfix._zw3 > div._524d > div > span:nth-child(3) However, it will randomly change from #u_0_2e to #u_0_2f or something similar. It's incredibly frustrating.Essentially what I'm trying to automate is if I post something to my Facebook page, it will take the link, click "Share" and automatically share it to another page that I select. However, Facebook's randomized selectors makes this next to impossible.I've tried searching for a solution, but I cannot find a single thing that will help me with this that will apply to async code.I just need something that will click the "Share" button, type in a phrase, and click "Share post to page."The usage for this is that if I post something to FB while mobile, it will automatically share it for me so that way I won't have to do it manually on mobile, which takes forever. Additionally, if I schedule posts, I want it to be able to be shared automatically. It's only shared in three locations on FB, so I do not plan on spamming.My backup ideas include:-try/catch. If there's an error finding selector 1, then try selector 2, etc.-clicking specific coordinates on the page-somehow figuring out how to search the text and click it, but ensuring that it matches the specific text I'm looking forAny help would be appreciated, thanks!

How do I pass data to a handlebars partial template?
So, I'm injecting the navbar into the main layout like this. Now, I wanna conditionally display the "Login" and "Logout" links in the navbar, depending on whether the use is logged in or not (obviously). In the app, I'm passing the user as req.user when rendering the "home" page, but I don't know how to utilise the user object in the navbar. Help!!! I'm a noob.

How should I handle unhandled promises node.js?
Should I do:Todo.find().then((todos)=>{ res.render('home', {todos}); },(e)=>{ res.status(400).send(e); }); Which means passing an arrow function to catch an error, or:Todo.find().then((todos)=>{ res.render('home', {todos}); }).catch((e)=>{ res.status(400).send(e); }); Remove the arrow function to catch an error and use a catch promise?

Passport failure redirect, react
Hi, I use axios to send a post request to my node js server. Then I use passport to authenticate the user. If the username and password are correct everything works fine. Unfortunately when one of them is incorrect my front end shows an error. I guess that happens because the passport.authenticate() middleware doesn't allow to access that route. I know that passport has something like a failure redirect but it doesn't work with react. Thanks for any help :)

How to boilerplate/bootstrap a REST API on NodeJS
Hi.I'm about to start a new NodeJS project for building a REST API. Which boilerplate/bootstrap code do you recommend me looking into for setting the project up?I need something like Swagger/OpenAPI, and I need to be able to implement a test driven development workflow so testing (with database mocking etc) will be important. Also, I'll be building the API on top of a PostreSQL server. The API will be run in Docker.
