I work as Angular and PHP developer. I try to learn node js with express. I think it's only a middle ware framework. Scene I aware of typescript, I choose nest js. I cool and easy. I don't need to learn new things. It makes it life easier for me. So framework you prefer and why. Is nest js is a good choice?

REST or Socket for Browser Based Game?
Hello everyone,I'm currently trying to build a smalll browser based MMO and need some advice. Let me preface this by saying I'm a frontend guy, and not too experienced with backend & security.Currently what I have is a React frontend & Express/Mongo REST server for the API. I'm using a JWT token to authorize API calls.I'm concerned that having endpoints that the users can potentially exploit might cause problems in the future.I don't know what best practice is but do you think having a socket connection rather than a REST API would be a more secure solution?

What is needed to deploy a fullstack app?
( Posted on another subreddit but posting here to get more responses)I'm new to this stuff. I know frontend quite well (HTML, CSS, JS), and know how to deploy it to static severs (GitHub Pages, for instance). It's very straightforward.What's confusing me though is being able to deploy a full-stack app (basically, one with front end and back end. Like say a project that has React on the front end and Node/Express on the backend). I tried deploying one to Heroku, but it seems like I have to deploy both parts separately? (i.e. deploy the back end and front end as sepereate entities/projects/apps and then link them together somehow). I don't get how the process works. It's much more difficult than basic front end.Do you guys get what I'm asking now? Basically, what is the list of steps needed for deploying a full-stack application?

What are the best practices to work with https/certificates in a project? Should I commit the certificate to the repository? Should I use the production certicate in my development environment?
I never really worked using https, recently I got to work in a project that requires https intead of http. It was quite easy to convert the http setup to https, but I have some doubts about how to handle certificates. From what I saw, the other developers from another project put the certificates inside a folder and commited it to the repository and used it in the development and production evironments.I don't think this is the best practice in this case, so I put the certificates in the gitignore and tryed to set up an self-signed certificate using openssl to work in development environment. The only thing that doesn't seem to work is that chrome browser complains about this certificate and I have to setup postman to accept it.What advice would you give me?

Help publishing soap endpoint protected by basic auth
I'll preface this with the disclaimmer that I am historically more of an infrastructure person, now in a position that I need to build several web services. Due to business requirements, I am trying to create what should be a very simple service using node-soap, exposing a soap endpoint protected by basic auth. I have followed the documentation to create a basic soap endpoint, which is working with a very basic wsdl, and I have followed the documentation for securing a Node service using basic auth.My problum is that Node is protecting everything except the /wsdl context with basic auth, but when I get into the soap.listen event basic auth is ignored and all unauthenticated requests are processed. I suspect I am missing something very basic, so anything you can point me to is appreciated. Searches and documentation seem primarily focused on calling a soap endpoint with basic auth and there don't seem to be any good examples of actually publishing such a service using Node.My server functionsvar server = http.createServer(function(request,response) {var credentials = auth(request);console.log('Checking credentials');if (!credentials || !check(credentials.name, credentials.pass)) {response.statusCode = 401response.setHeader('WWW-Authenticate', 'Basic realm="example"')response.end('Access denied')}response.end('404: Not Found: ' + request.url);});function check(name, pass) {var valid = true//Simple method to prevent short-circut and use timing-safe comparevalid = compare(name, 'john') && validvalid = compare(pass, 'secret') && validreturn valid}server.listen(8000);soap.listen(server, '/wsdl', WorkOrderService, xml, function(){var authorized = check('user','pass');soap.authorizeConnection = function() {return false;};console.log('server initialized');});I've tried placing the check call into the soap.listener, and tried both false and true for the soap.authorizeConnection. As mentioned, I'm new to both SOAP and Node, so please do not be shy about pointing out the basics.

Senior Devs: Looking for feedback on basic password hashing strategy
I'm implementing basic password hashing/validation using Node/Express/Bookshelf/Postgres. crypto module for encryption. I'd appreciate critique/feedback // protocol.config.js const protocols = { 'v1': { keylen: 64, digest: 'sha512', iterations: 100000, encoding: 'hex', salt: { size: 128, encoding: 'base64' }, }, } // UserModel.js class User extends bookshelf.Model { get password(){ return this.attributes.password; } get salt(){ return this.attributes.salt; } get protocol(){ return 'v1' } static async generateSalt(config){ const buf = await randomBytes(config.size); return buf.toString(config.encoding); } static async encrypt(string, salt, config){ const derivedKey = await pbkdf2(string, salt, config.iterations, config.keylen, config.digest); return derivedKey.toString(config.encoding); } static async save({ password, ...data }){ const salt = await User.generateSalt(protocols[this.protocol].salt); const hash = await User.encrypt(password, salt, protocols[this.protocol]); const hashSaltProtocol = String.prototype.concat.call(hash, '$', salt, '$', this.protocol); return this.forge({ ...data, password: hashSaltProtocol }).save(); } async comparePassword(string){ const [password, salt, protocol] = this.password.split('$'); const hash = await User.encrypt(string, salt, protocols[protocol]); return crypto.timingSafeEqual( Buffer.from(password, protocols[protocol].encoding), Buffer.from(hash, protocols[protocol].encoding) ); } } High level explanation:Save all password protocols in external file.Set current password protocol on the model.Password is hashed using current protocol.Random salt is generated using current protocol.Password, salt and version are saved together in password field in User table. ie "passwordhash$salt$version"When user submits a password for validation, the saved password is retrieved from table and split.Submitted password is encrypted using salt and version of the saved password.Password and submitted password are compared using timingSafeEqual instead of naive comparison (i.e. "===");The big idea is that I want a flexible solution for bumping password hashing protocols without impacting passwords hashed from previous versions or storing that data in the table.

Controller that creates bank transaction with some rules
Hello, guys! I need to create a simulation of a bank transaction with a few specific rules.For example, if the type of the payment is done with a debit card, it must be charged a fee of 3.2%.For now I could not set up the rules in the controller yet. Could someone help me out? Here is how my current controller looks like:javascript async store(req, res) { const { type_transaction } = req.body; if (type_transaction === 'debit') { let { value } = req.body; return value += 32; // random value just to test if it'll be saved in the db } const transaction = await Transaction.create(req.body); return res.json(transaction); }With the method above, I'm able to change the value, but I'm not able to save the changed value to the DB. Like the image below:https://user-images.githubusercontent.com/16469917/65846188-54e9c100-e313-11e9-8fb5-6f0173dd514d.pngThis is how the Transaction Model looks like now:```javascript class Transaction extends Model { static init(sequelize) { super.init( { value: Sequelize.INTEGER, description: Sequelize.STRING, type_transaction: Sequelize.STRING, installments: Sequelize.INTEGER, }, { sequelize, }, );return this; // ...

How would I chain these promises together in order to prevent that from happening?Thanks!

I created a cli tool that lets you create quick and simple scaffolds for Discord bots
Hi,A few days ago it occurred to me that I was getting tired of re-writing my bot templates over and over again.I felt like this could help some beginners out with having a proper structure and keeping it organized, instead of having all of their files jumbled up together. The angular cli inspired me. I also tried to see if there were any cli tools that did this, I wasn't able to find any from Google but hopefully there's room for another one if there exists one already.As of right now only discord.js projects work and you need a Node version that supports fs promises but I will change that soon because I understand some people may have older versions, and fs.promises is still experimental i think.GitHub: https://github.com/ansonfoong/djs-cli-toolNPM: https://www.npmjs.com/package/discordjs-cliYou can create either a plain discord.js project, or one with the commando framework. You can also generate commands and events, and it will build a basic template for you. Currently still trying to find other potential bugs and also working on other features to support more arguments. But if anyone here is interested in checking out the source code and giving me advice I would appreciate it.

I created a ORM using Redis, suitable for microservices
Here is the library, please enjoy:https://www.npmjs.com/package/ts-redis-ormFeatures highlight:Simple class structure using typescript decorator. (Very similar to type-orm)Using native JS value types (Number, String, Boolean, Date, Array, Object).Atomic. All redis logics are written in Lua to protect data integrity.Schema validation and database reSync.Support multiple index keys and unique keys.Built-in entity timestamps (createdAt, updatedAt, deletedAt) .Soft delete.Aggregate functions (count, sum, min, max, average).You do not need to initialize a connection before using the entity. It's all done internally.Import / Export DB into file.Good Performance. You can create around 10, 000 entities in 1 second for 1 CPU process. Query is also extremely effective with proper indexing settings.

XSRF and Node (2019)
Hi all!Unless I am mistaken, the `csurf` npm package is basically an implementation of an Encryption Based Token.Which means that the secret used to generate the token should be kept server side.Since one usually generates this token and secret when a session is created, it makes sense to store the secret in the session store, along with other values. So far, so good - I hope.Thing is, I decided to get rid of session stores, due to many considerations, and have decided to use a JWT based session mechanism, persisted in a cookie (Secure,HttpOnly,SameSite + Supported Browser Filtration).This means that the XSRF secret will be stored in the Session JWT token as well, which contradicts the whole purpose of a secret. The question is, does doing so expose an attack vector? (and I mean an actual one, not a wild theoretical scenario).Are there any alternatives to this package which are actively maintained?P.S: my first ever post on reddit, so sorry if I did / said something wrong.Thanks :)

There has to be an easier way to do what I'm trying to do..
So I'm working on an automation project for work, and powershell (Invoke-WebRequest) wasn't cutting it due to lots of security settings on our internal sites.so I switched over to Puppeteer for the browser automation piece - very new to JS and puppeteer, pretty much learning as I go.Have most of the script completed and working, and it does work as is, but I'm thinking there is a way to make it easier.It really just logs into our site, clicks a few buttons, and then fills in the form to create a new user, which includes some text boxes and a few dropdowns.They coded these websites in kind of a shitty way, and on this user creation page, I can't get any clicks to actually work because Puppeteer doesn't like the selectors of any of the fields.got around this by just tabbing through the different fields and then typing the info.the issue then is the dropdowns.a few of these dropdowns have 50-100 different options and any one of them could potentially be used.so right now, it works, but it includes a shitload of these:await page.keyboard.press('ArrowDown'); We're talking 1000 lines just for one dropdown.I'm thinking there has to be an easier way to simulate a ton of these in a row.I don't want my script to actually list 75 of these lines when I want to arrow down to a specific item in the dropdown.I have another script that uses {clickCount: #} to simulate repeated clicks, but I can't find anything similar that works for presses.anyone have any ideas?

I made HideJS for the times I wanted to demonstrate a web app without revealing any source code.
The site is HideJS, hosted as a Heroku app with NodeJS + Puppeteer backend. You just enter a URL (to your website or web app), click the button, and it encrypts it for you to share. Others take the encrypted string and submit it in the same box. The encryption part is (maybe obviously) so they can't just visit the direct URL instead and see your source code.If you're patient for maybe 5 seconds (?) an interactive stream of the site will be established. The experience should be exactly the same as visiting the actual site, except without sound and with a low framerate. And of course, the complete inability to see any source code. It turns any web app or site into a blackbox.Try visiting this link to see it in action: (can you guess what it is?)https://hidejs.herokuapp.com/4dd42e87e0c8644f185a8d345e35c5c0ba54bbbd5195072c646a375de3a1fedcDON'T click the blue button when you visit the link! Just let it load =)I've only tried it on Chrome on a Windows x64 Laptop. Try selecting text, copying it with CTRL + C and pasting it into a form with CTRL + V. Or watching YouTube videos (without sound, sadly).Maybe this is mundane stuff to everyone who's had to use Puppeteer for their dayjob. But to me, it feels kind of magical. What do you think?It works with Canvas so you can actually play games through it (I confirmed this), but for some reason WebGL doesn't render. I do intend to fix that.I know Browserless.IO does something similar to this but it's focused on debugging and headless automation, not for blackboxing demos of web apps.To be honest I did not do a TON of research into seeing if there already existed something like this for this purpose, but what searching I did do didn't yield anything. If you do know of something like this please share!Thanks for reading.EDIT: By the way I am struggling to find a way to simulate mouse wheel events. I can't even get them to work in regular Chrome. If someone could help me out with that I'd be very grateful, I tried all the solutions on stackoverflow but none of them have worked. So I'm simulating up and down arrow keys on Puppeteer as a replacement.

I built module for working with JSON. It's working but alpha. How useful is it? Should I continue?
I feel like a lot of JS applications rely on JSON.parse / JSON.stringifyBut then one day they grow up a little and run into JSON that is bigger than they initially allowed for. Whether one huge JSON that is too big to even fit in memory, or just JSON that's big enough that for not blocking you just don't want to process it synchronously.So, I built a drop-in replacement from JSON that works asynchronously. Just change JSON.parse(string) to await JSLOB.parse(stringOrStream) and the same for stringify/streamifyIt stores the key value pairs in any level compliant DB, which you can pass in, whether you want it to be in-memory, on-disk, or clustered.So loading/serializing is working fine, as well as asynchronously accessing properties on the resulting object (see README for examples)But, there's just a ton of other functionality to built, like asynchronous setting, iterating keys, etc. Not to mention code clean up.I'm trying to figure out whether this is worth working on further. Would this be valuable to someone? I imagine it should be, both in data engineering use cases, as well as simply having your webserver not block while it tries to parse a large JSON sent by a user (without having to tediously rewrite your code to stream)Here's the project: https://www.npmjs.com/package/jslobThoughts?

I have one doubt about what http status code should I return in my nodejs api if a request tries to find an user, but its not found in the database.
Hi, today I was writing an test code for my api, there's a route '/confirm-user', that tries to find the username send in the body of the request and returns its userId if one is found.But I started writing the case where the user was not found, because the username was not in the database, so I tested for a response status of 404, not found. The test passed and I proceed to the next. It was then that I noticed that I didn't even set my /confirm-user to the app, so the 404 I got was an generic 404 that returns everytime a wrong request is sent.That let me to think that maybe the correct response was 200, signaling that the request was on a right endpoint, with an message in the body of the response warning the the user was not found in the database. Is this the right approuch in this situation? Is there a best practice guideline for what should be the correct status code response?

I know about Sequlize, but heard that it generates complex SQL.So those who are constantly working with Node JS, please suggest some good SQL ORMs. Currently, I work with Node only when I am permitted to work with NoSQL databases (because NoSQL/Mongo suits better with Javascript). But when I have to use SQL (which is in most cases), I try to avoid Node because of ORM. Please note that I haven't used any Node ORM before.

Setting up a website, I have some questions...
So I've been doing some research on setting up websites in Node.js and it seems that Express is a pretty good one to use, it even has that express-generate command that sets up a basic project to start from.Now, I'm no stranger to frontend web development. I know my way around HTML/JS/CSS and part of what draws me to Node is that I already know Javascript.I ran `express-generate` and use hbs as the templating engine since it's very close to HTML and it makes a lot of sense to me, and I also set it to use SASS instead of CSS. It runs, it's all good and all, but my research has only opened up more questions.It seems like there is always a "You should use ___!" around every corner. I plan on having a database connection on my site, and I know MySQL. So I look at getting that on there, and after installing mysql apparently there is a faster and better mysql 2 I should use. Not only that, but I should use something like Knex to build the database queries. In fact, I should use an ORM so I should use something like Sequelize but recently people said Objection is way better than Sequelize and to use that instead. Even so, this article says I shouldn't use an ORM. After looking into this, I found out that the default hbs that express comes with has a vulnerability, and that I should instead use something like express-hbs, or better yet, express-handlebars, for my templating engine. I also want to get Bootstrap working in my site, so I could use a CDN or as some people suggest I should use `npm install bootstrap` but while I'm at it apparently webpack is another one to use to put resources together, but in order for some of it to compile together I should add Gulp to the mix? What about Babel, Browserify, jspm, Grunt, Yeoman, or Slush? This is confusing borderline intimidating...I spent a week adding things, reading things, trying things, resetting my project, going back and testing things, and comparing things. I'm currently using express, express-handlebars, and objection (ORM) with mysql2.Before I go any further in reading and considering extra stuff, I figured there's no harm in reaching out and asking for help r/node please help me out.First off, are there any packages that I should know about that I had not already mentioned? I'm somewhat new to this, so please just assume I know very little.Secondly, I feel like there are many rabbit holes that I could hall in and I don't know what paths I should be taking. I'm scared that if I ignore these extra packages and options I will regret them down the road, but I'm also scared that they're absolutely not mandatory and adding them to my project will just make things harder and will end up being a fat a waste of time. Could you please give me advice on this?EDIT: I did some reading and found this fun read and now I can relate to all the confusion.

[Help] Creating 1st Party vs 3rd Party Access REST API?
Hello,So I'm working on building my own Full Stack Web App. Let's call it "SocialFora". I have a simple Vue client/Node backend setup. Now, based on this info, my Vue client is the 1st party application because it's internal to, let's say "my business". Meaning if users want to login, they go to the site /login. etc. Now, let's say my users want to build their own 3rd party applications to access their stuff. That means I would need to give them access to my "API".In that case, does this "API" that my users are building for the same API that my 1st party vue client is accessing? or is it a separate project API specifically for handling 3rd party access?If the 1st party and 3rd party are indeed accessing the same API backend, then I'm guessing both 1st party and 3rd party applications are using different forms of OAuth2 access methods? (Assuming Password for 1st party, Auth Code for 3rd party).I've searched the web on this topic, but there's nothing that talks about both parties.Your wisdom is very much appreciated! :)Thanks.

Command queing for ASCII based protocol over TCP socket
Hi,I'm trying to write some configuration software for a device. The device is configured via a serial interface with an ascii based protocol. Command messages are simple strings ending in a carraige return. When a valid command message is received, the device responds with "OK".To interface with the device I've got an RS232 to IP converter, which my node.js app connects to with a TCP socket.I've been able to succesfully send commands with socket.write(command), and parsing the output of the device to get a variable "deviceoutput" with value "OK" works ok as well.The issue I'm having is that I want to send multiple commands to my node.js app, queue them, send the first one but wait to send the next until the "OK" message from the device has been returned.Creating the queue seems simple enough by doing:function Queue() {this.data = [];}Queue.prototype.add = function(record) {this.data.unshift(record);};Queue.prototype.remove = function() {this.data.pop();};Queue.prototype.first = function() {return this.data[0];};Queue.prototype.last = function() {return this.data[this.data.length - 1];};Queue.prototype.size = function() {return this.data.length;};const commandQueue = new Queue();Has anybody tried something similar in the past?

What to do next?
Hey friends.I’m going all in on Node and React while trying to land my first full time developer job, and I want to challenge myself with something new using Node.I’ve done a lot with it already, but right now I’m creating a chat and video sharing app using web sockets. Once this is done, I’m not sure what to go learn and work on afterwards. I’ve built a few full stack CRUD applications with authentication at this point and just don’t know where to go next.A list of things I feel comfortable doing with Node:-Basic web server to host files and applications -API creation and management (Express)-Interacting with both SQL and noSQL databases (Sequelize, mysql2, Mongoose)-A really simple command line RPG game using inquirer-Interacting with Firebase using Firebase tools and SDK-Interacting with the file system to change and overwrite some txt files-User authentication with JWT and sessions, mostly using passport and some oauth providers-Currently playing with websocketsAny guidance or reading you can give me would be really helpful - I really like Node’s architecture and the fact that it’s easy to hop between front end work (React) and back end since they both use JS; and I’d like to keep going. Thanks a ton.

Making a backend with an encrypted database?
So I'm interested in making an app where I want some of the data in the db (probably mysql) to be encrypted. I don't really know much about security and encryption stuff, but this app will be for personal use only so it's a good learning opportunity and not a big deal if I get something wrong. I guess this is more of a general backend question, but I do want to do it in nodejs.I also don't want the users to have to enter two passwords to use the app (once to log in and once to access their data).Do you guys have any articles or libraries that help handle this sort of stuff? My layman's theory is that there would be some sort of encryption key, which is generated from the user's password. When the user logs in, we generate the key and store it to localstorage. That way the plain text password isn't stored anywhere, and nothing is stored on the server that could be used to see the data. Then, with every request, we send the key along, so the server can return plain text data (or encrypt data that's being submitted).There's probably a billion security holes in that strategy, but I'm ready to learn! :P

Should I use JWT or sessions for authentication with a templated front end (EJS)?
My current setup is Node, Express, Mongo DB, and jsonwebtoken for authentication. I have authentication working fine through the REST API (for mobile application use). The problem: the front end is not a SPA, it is rendered using a templating engine (EJS).My current train of thought is to also use JWT for the EJS front end and send the JWT through the header. Is this bad practice? Should I use sessions for the EJS portion and JWT for the mobile app portion?

Compile typescript on NPM package install
Hey, im looking for a a best way of handling shared code in my company in typescript. Previously we used symbolic links to make the folders appear inside the project but I came up with a better solution to leverage NPM local file references which still create symbolic links but in the node modules folder and with the nom install command.I achieved this by changing the post install script to npm prune (seems to download modules without causing recursion), rm -rf dist (remove the build directory) and tsc (to compile).This has been working moderately well until today when i was nesting a shared package inside another shared package which didnt work. Any advice on a better solution that doesnt involve storing build artifacts or publishing private code to the npm repo.tl;dr is there a better way to do ‘npm prune && rm -rf dist/ && tsc’?

I've heard that its a good idea to have a clear separation between back-end logic and front end logic, and that extra care should be taken with running Next on the same server as your back-end as not to risk allowing to much back-end/DB exposure via your front-end app.What is the ideal solution for this? Containers...?

Using MEVN stack, got a specific question about image upload with Multer. PLZ...
I have a rather specific question about Multer. I'm using the MEVN stack and managed to upload images to my server with Multer using a specific model with just one field for the image that looks like this:const image = new Image({file: req.file.path,});That worked fine. Before sending the image from my frontend, I converted it to a FormData object. So I did this:await axios.post(urlImage, formData);All good, easy peasy. However, I am trying to save an image in the following way with a 'person' model:const person = new Person({personData: {image: req.body.personData.file.path,basicInformation: req.body.personData.basicInformation,profile: req.body.personData.profile,experience: req.body.personData.experience,education: req.body.personData.education,skills: req.body.personData.skills,hobbies: req.body.personData.hobbies}});On the frontend with Vuejs I'm sending a Person object, that contains an image field that holds the formData and the rest of the fields are arrays of objects. Normally with Multer, the image is accessible with req.file.path as I did in the first example*.* But as you can see the FormData objects lives in req.body in the Person object*,* effectively making it (as far as I know) undefined with Multer. Whatever I try, the 'req.file' is always undefined because of it. Is there no possible way to achieve this with Multer? I've got multiple posts on stackoverflow with zero answers. Am I stupid or something?

Unix Management
Necessity to use CLI is appeared increasingly during any project development. Inevitably, an automation process has to be designed.IntroductionAny ordinary project requires documentation. We have a pair kinds of documentation during development, TypeDoc & JSDoc. The finish variant of our documentation is a HTML files directory, generated with documentation tool. You know, it would be great for me as a developer to run documentation on a third-party server. Third-party server is nothing less than good old Docker) container. Running of Docker container is nothing more than Unix Management system through Command-line interface, CLI.What do we face at every step of project documentation management? Documentation generation tools, CLI. No matter how little is said both mentioned directions provide the enormous range of informatics tools and methodologies. Let’s not dwell on methodologies today, but let’s try to dive into Command-line Interface.CLISo what is the CLI and what does automation have to do with it? CLI is represented the text interface between human and Unix system where the instructions are provided with commands, text strings. The command is represented the command name and its ?parameters. Typing of Unix commands is absent, but the common approach is governed.So, let's consider the process of creating project documentation. Our project consists of JavaScript & TypeScript code. We can automate the process of code documentation generation with JSDoc & TypeDoc. We can use next commands to generate documentation:TypeDoc: typedoc --out .docs/ts/html --readme ./docs/README.md ./srcJSDoc: jsdoc ./ -d ./.docs/js/html -R ./docs/README.mdCurrent action automation is supported with npm-scripts.Generated documentation is no more than HTML files set. Let’s create out separate server to run documentation, as mentioned above. To run server we can use default tools: Docker, Docker Compose.Separate server to run documentationDocker Compose files:docker-compose.ymldocs.docker-compose.ymlNode.js CLI utilities are used to build the initial step in automating the process of creating a documentation server.ConclusionSo, it’s clear how it works. The one problem of development is visible. Our actions are represented any development tools, but CLI is represented the text information only. As a developer, I would be pleased to work not with textual information, but with variables, objects, classes, etc. It’s worth nothing that the server creation is represented commands dendritic hierarchy. Let’s try to figure out the two points above.Ok. Let’s stop for a while.

Linking Vue.js and Express behind a Nginx reverse proxy
I'm very new to the node world and I am slightly struggling to get my vue.js frontend to communicate with my express backend. Locally I can do it no problem, but I am stuck trying to do it on my server.Nginx is serving as a reverse proxy, my current config has www.x.com/upload traffic sent to the express server and all other traffic sent to the vue server. I am using dropzone to upload the files.All data is sent when I upload according to the network tool in chrome, but the file doesn't appear in the express server and dropzone never shows 'upload success' like it would when run locally. I'm not really sure what's wrong, data is being sent to the right location, and I don't know why express wouldn't handle it properly. It must be a config issue since everything runs locally but I am a bit lost. Any help would be very much appreciated.My current express index.js is simplyconst express = require('express'); const multer = require('multer'); const cors = require('cors'); const app = express(); app.use(cors()); const upload = multer({ dest:'./uploads/' }) app.post('/upload',upload.single('file'), (req, res) => { res.json({file:req.file}); }); app.listen(3000,()=> console.log("Running on localhost:3000")); Thanks!

I am looking to create a web app that makes live streaming user friendly for church's as I've pulled out plenty of hair trying to learn how to do so for my church. I'm looking to make essentially a rtmp ingest server that handles streaming to Facebook, YouTube, etc. similar to restream.io.I've seen some ideas thrown around using node and ffmpeg with spawning child processes. I have a little experience with docker as well. Not sure if that helps with performance.Please feel free to share resources/ideas. Extremely eager to learn! Also interested in production optimization (never single handedly sent an app to production). Thanks so much!

Should I learn Express, Koa, or Hapi? Will documentation for one work for the rest?
I'm familiar with Node.Js because I built a serverless web application using AWS Lambda functions. I'm no expert, but I can use Node and NPM. I also have experience with JS. I want to learn a new framework to build totally new projects from the ground up.Express has a huge community and every tutorial or package I find online seems to be geared towards Express. It makes me feel less intimidated knowing that there's a huge amount of resources that I can fall back on.Koa seems to be marketed as a strictly 'better' version of Express. Its biggest drawback is that it has a smaller community.Hapi seems to be recommended a lot around here. I read the guiding principles of how Hapi was designed and I love them. They have an emphasis on readability, but no "magic" happening behind the scenes (unlike Ruby). They've also got an emphasis on security.Are tutorials and packages that I find for express going to work the same on Koa or Hapi? Will the authentication process be the same? Which one of these should I choose to learn.

Correct way of creating a realtime application with Cassandra
Right now I have a ec2 instance running Cassandra and a simple websocket server. Is there anything I am missing and I would like to know if this is the correct way to make a "real time" chat application?Client connects to websocket, inserts a message, the message is stored into database, and the message is then sent to users if the record to the database is successful.const cassandra = require('cassandra-driver'); const client = new cassandra.Client({ contactPoints: ['127.0.0.1'], localDataCenter: 'datacenter1' }); const WebSocket = require('ws'); const wss = new WebSocket.Server({ port: 3000 }); wss.on('connection', function connection(ws) { ws.on('message', function incoming(message) { //Insert message into Cassandra DB client.connect() .then(function () { return client.execute('SELECT * FROM test_keyspace.users'); }) .then(function (result) { const row = result.rows; console.log('Obtained row: ', row); response.status(200).json(result.rows); //Send message to other users if record in db is successful }) .catch(function (err) { console.error('There was an error when connecting', err); return client.shutdown().then(() => { throw err; }); }); }); //Then send messages to users connected to the websocket in chatroom ws.on('close', function(){ console.log("I lost a client"); }); });

How to make Node.js as much secure as java(back-end)?
I have been working on node.js for 1 and a half year now. But there is always one question in my mind that I always get to hear, "Node.js is not as much secure as java". Although, we can use oops concept in javascript and make the variables parsed to strictly typed variables. So, what should be done to make Node.js as much secure as it can be?

Lock for a reservation service.
I don’t know if this is the right place for the question, but I’m working on system to place reservation for a spot. I’m using an angular frontend with a node backend and Firebase Firestore DB.What I want to achieve is that when you want to reserve a spot. You get n minutes to complete the reservation. When n minutes has passed the spot is given free again. My question is where to store and implement the mechanism to give the spot free again? I don’t want to keep track of it (only) in the frontend. Is a redis instance with a key and expiration time the way to go? Or is that overkill?

Can any one help me with this Redis script?
I have a redis script that, in production, is run as a cron job. I did some edits, and am trying to test it before I send it back to my boss. I'm pretty sure the code is all correct, but the script doesn't seem to be working.Essentially, I am using redis to track server calls, and every so often these redis logs get saved to our Mongo database. When they are saved to Mongo, two things happen. 1) I loop through all redis keys and save them to Mongo. then I add a field to the redis file with a key of 'backUp' and a value of 'true' 2) I again loop through all the redis keys, and if there is a key of 'backUp' with a value of 'true' I delete that key.Because I am just trying to test this script without the whole app running, I've added a single redis document with 'client.hmset'. I've also added some log statements, and at the bottom I added some code that lets me run the file as a script.Here is the code:const db = require('../mongodb') const analyticsRepo = require('../app/repos/analytics') const ObjectID = require('mongodb').ObjectID let Binary = require('mongodb').Binary const redis = require('redis') const client = redis.createClient({ port: 6379 }) let start exports.start = start = function (cb) { console.log('start ()') client.hmset(['newHASH', 'route', 'routeValue', 'ipAddress', 'ipAddressValue'], function (err, res) { if (err) { console.log(err) } console.log(res) client.keys('*', function (err, keys) { // gets all hashes in redis db, returns them as 'keys' if (err) { console.log(err) } console.log('keys: ' + keys) for (let i = 0, len = keys.length; i < len; i++) { // loop through all keys client.hgetall(keys[i], function (err, results) { // gets all key/value pairs from keys[i], returns them as 'results' if (err) { console.log(err) } /* --inserts the object to be stored in Mongo db using the key/value pairs from 'results'-- */ const newLog = { route: results.route, ipAddress: Binary(results.ipAddress), // converts string to binary userId: new ObjectID(results.userId), // converts string to Mongo ObjectID timestamp: Date.parse(results.timestamp) // converts string to unix timestamp } analyticsRepo.create(newLog, function (err, insert) { if (err) { console.log(err) } }) // add backup field to keys[i] after saved to Mongo client.hset([keys[i], 'backup', 'true'], (err, backup) => { if (err) { console.log(err) } }) }) } }) // 2nd iteration of all hashes in redis client.keys('*', function (err, keys) { // gets all hashes in redis db, returns them as 'keys' if (err) { console.log(err) } for (let i = 0, len = keys.length; i < len; i++) { // delete the hash from redis client.hget([keys[i], 'backup'], (err, backupField) => { if (err) { console.log(err) } if (backupField === 'true') { client.del(keys[i], (err, success) => { if (err) { console.log(err) } console.log('record deleted') }) } }) } }) }) cb() } const redisToMongo = async function () { await db.init(function (err, results) { if (err) { console.error(err) return process.exit(1) } else { console.log('program begin') start(() => { process.exit() }) } }) } let args = process.argv[1] if (args === 'LOCAL PATH') { redisToMongo().then(() => { console.log('program run') }) } When I call the `redisToMongo` function at the bottom, I have a log statement that logs 'program run'. This log works correctly. Similarly, within the `redisToMongo` function I have a log statement that logs 'program begin'. This log works correctly. Similarly the first line of the `start` function, which has all the "real" code. has a log statement that logs 'star t()'. This log works, but nothing else seems to work. My client.hmset call should either log an error or success statement but neither on happens.Presumable if this were working, the redis document would be created, and then saved to my MongoDB, but this doesn't happen. And just to be sure, I tried calling a 'bad' redis command like 'hset123()'. This threw an error just like it should.How is it possible that I'm getting no errors, no log statements, and no successful additions to my database? Can someone please help me out here? Like I said, I'm pretty confident that the actual redis code is correct; I think I just don't know how to get this script to run or something...

Need some advice and feedback: generating charts from data and then integrating them into emails
I'd like to know how to add nice and smooth charts in the emails my application send to my clients. Don't know how to implement it exactly but I'm sure it'll make these weekly emails appealing. Has somebody already done that?My Node application uses Sengrid services to send emails and I already have a Cloudinary account for pictures storage. Is it possible to generate a full SVG or Base64 image to direct integration in emails? Should I generate pictures with a backend worker/script in Python or JS, push them in the cloud through the Cloudinary API and add a simple link in my emails? Is it easy/possible/desirable to use an online API which provides "chart a a service" and integrate magic links in emails?I'd like some advices from people who already did it successfully because I know how HTML/CSS and images/links security for emails is a pain in the ass.PS : maybe https://www.image-charts.com/ ?

Best practice for MERN deployment
Greetings all,Currently I have a website that is two separate domains, one for the ExpressJs/Mongo backend, and a React/Next/Express for dynamic routes frontend. Is this a common situation?Also, is docker a best practice as well? In my case, since the front end and back end are on separate domains, how would a docker-compose file control that? Is Docker the best practice or a MERN application deployment? I do like it for development.Right now I have just deployed my application without Docker, and it works fine. I'm really just looking for the best way to deploy a mern, or any node app for that matter. Specifically speaking, Docker and Frontend/backend separation.

What would you suggest as in final quarter of 2019 to use Typescript or Javascript(without Babel) for a Node.js/express backend to use?
A Js dev by choice but not a fan-boy. Well awared of oops (regular and js based prototypal ) concepts and developement practices . I know basics of typescript ( worked alongside Angular devs and done oops heavy courses in Java, C#, etc in college) will brush up in 2-3 days.If I go with typescript this will be my first node(backend) project in it. My main focus is on maintainability of source code and scalability.I have basic or you can say superficial knowledge about Sql. Probabily going with Mysql/MariaDb ( gone through the pain of everything NoSQL :) )Last but not least project has a tight initial time line and possibly their will be no transitioning time from POC/MVP to market ready (actual concept is already build using CakePhp and in bad condition, both backend & frontend, not marketable enough and misses key feautures e.g. it is a static site with bunch of forms and admin portal). But it will be a long-term project.These days I am seeing lots of "Typescript is not Javascript" posts over internet and various pain points that Ts devs face when Ts have inconsistent behaviour after transpilation.So have to make a quick call. What would you suggest? And if you advice me to go with TS can you suggest some articles and tutorials to scaffold a backend project in Ts.

What web server should you use with node?
A little back story, I’m a SysAdmin and have a decent understanding of how to use traditional web servers (IIS, Apache). I took a work sponsored bootcamp on full stack development (with Node) and it was interesting. My work, now wants me to rebuild one of our internal sites, cool! In class we used Express on our local machines. We never really discussed what we should use (or how) for a production app? Is Express acceptable, are there better options? What do you use for process monitoring? To complicate things I’m look at hosting in AWS. (deciding between using Beanstalk or trying to setup EC2/RDS)

Does Node natively limit the size of data in the body of requests?
It is very simple to set up an api in node where you can accept various different requests, like POST or PUT requests where the user can send information in the body in the request.So I was wondering if node can natively limit the size of the data or if there are libraries/middlewares that can handle this in express or other api frameworks.An example would if I set up a POST endpoint where a user can create a Person with different properties like name, age and so on. So if the user decides to send multiple gigabytes worth of data in the request, how would one stop node from trying to load all of it in memory and crash the application due to node using up all the available memory.I know there are libraries to validate request bodies like Joi where you can for example specify the max amount of characters in a string but this can only be done after node handles the incoming request and saves all the data.

Handling requests on Express server
I have a simple Express API service with a few endpoints. The APIs are used by the frontend to read/write data from Elasticsearch (ES). The said endpoints are described below.1. /api/storeCities # parses a CSV and writes 100,000 documents to the cities index in ES 2. /api/fetchCities # fetches 100,000 documents from the cities index in ES 3. /api/fetchStates # fetches 100,000 documents from the states index in ES 4. /api/fetchCountries # fetches 100,000 documents from the countries index in ESQ1. For all the fetch endpoints above, I have no problem/latency fetching data into the UI. Since node supports 1000s of concurrent requests, there shouldn't be any problem multiple users calling the same API (?).Q2a. Whenever someone calls the /api/storeCities endpoint, node parses a CSV file and writes data to ES. However during this process, all other endpoints stop responding and there's huge lag from all the fetch endpoints. Since node is non-blocking, why is the WRITE operation affecting the READ ones? Is this a problem on the ES front?Q2b. I am also using the node Cluster module so there are multiple instances of my Express app. However, the lag still persists when someone calls the /api/storeCities endpoint. It seems like node is blocking all the READ calls from ES until the WRITE call is finished.I am unable to pinpoint where the problem is, node or ES?

I built an app to keep track of my followers in all my accounts with VueJs + ExpressJs + MySql
Hi everyone.For the last 3 weeks, I’ve been working on the following project. The thing is I own several accounts for my projects (Instagram, Twitter, MailChimp, GitHub, etc). So it was really hard to keep track of how my audience was growing (or not) in any of them.So I decided to build my own solution. I create a very simple app, that sends directly to your inbox a report showing the followers (subscribers, etc) you have in your accounts. Also, it saves the historical data, so it shows how much your audience has grown.For the tech lovers (I would love to answer any technical questions if you have any):Backend: ExpressJS (Node),FE: Vuejs off course + Bulma + BuefyBD: Mysql DB + Sequelize JSQueues: BullOther tools: Nodemailer, vue-analyticsAPIs integrated: YouTube, Twitter, MailChimp, Convertkit, Instagram and GitHub.I posted about it first in /r/vuejs and some interesting questions came up:Why I choose Bulma instead of Vuetify?Sincerely I recommend both, I think that Bulma is prettier/attractive than Vuetify, but Vuetify is more powerful and flexible than Bulma. So, I would say if your project will need complex pages, with a lot of components I would recommend Vuetify, but if your project is more focused on a clean and visually beautiful UI I would go for Bulma.Which was the hardest API work with?YouTube API was pretty easy to integrate using the googleapis (https://github.com/googleapis/google-api-nodejs-client).Twitter was a bit tedious, because you have to submit for a dev account first to get permissions to use it, and you have to fill a lot of questions and stuff, but then is easy using https://github.com/desmondmorris/node-twitter.But the worst was Instagram, I ended up using a workaround to get the followers from a search GET query that returns a JSON, but I'm not actually using the API.Why did I choose to send the report by email instead display them in a dashboard?I choose an email report because I don’t want another app to remember. I prefer to receive a scheduled report that I could check (daily or weekly) when I read my emails. Easy and simple. I tell you, is really exciting to check your emails and see that you have received a new report, willing to see if your audience is growing. As I really enjoyed the result, I decided to release it to the world. Is FREE, but I added a premium plan, to see if I can make some money with it haha.The app is https://trackmyaudience.xyz, let me know what do you think, any feedback is appreciated.TL;DRI own several accounts for my projects so it was really hard to keep track of how my audience was growing (or not). I built https://trackmyaudience.xyz, a very simple app, that sends directly to your inbox a report showing the number of followers (subscribers, etc) you have in your accounts

Concurrency in Node.js
One of my colleagues has written an article about concurrency in Node.js. He mentioned its general idea and pointed out some traps that may come with it. You can check it out on the blog. What do you think about it?

Giving Command Line Application a GUI
Hello! First time poster and also not very experienced with Node but I have an application that is basically a game queue system.After a certain amount of people join the queue it sends every user a message on the CLI that a match was found and gives the user an IP address to connect to. I was wondering if there are ways to port this to a GUI so users can click a button and when the match is found it displays the text that would usually appear on the CLI on a GUI instead.I’ve found UGUI as a potential solution but I was wondering if anyone experienced in doing this has a better solution or thinks that UGUI would work for what i’m trying to do. (Also sorry for formatting i’m on mobile)Thanks!

Download file retrieved from AWS via NodJs over Angular?
User clicks on link, in Angular link has a bound function that sends a get request to NodeJS, I can see that NodJs gets the file/buffer stuff, and now I've been stuck on how to send file to user. Here is the current logic: app.get('/api/file', (req, res) => { let params = { 'Bucket': awsFun.createBucketName(req), 'Key': req.query.fileName } s3.getObject(params, (err, data) => { if (err) console.log(err, err.stack); else res.status(200).send(data); }); });

What do you use to control access to your API resources ?
Giving a logged in user access to only the resources s.he owns seems like a common use case on paper.In reality, I couldn't find that many examples and tutorials.

Is there a way to run npm scripts with forever.json?
I am trying to use forever as it's shown in the documentation. I created a json file and added something like this[ { // App1 "uid": "app1", "script": "index.js", "sourceDir": "/home/myuser/app1" } ] And it works, I run it like so:forever start /home/myuser/app/forever/development.jsonBut, projects created through create-react-app don't have an entry point but they have npm start. So is there a way to run npm start in the above setup?In the terminal I could do this: forever start -c "npm start" /home/myuser/app1 but it be supper hand to be able to add all my apps into a json file (the first example).Is there a way to do it?

How to handle time based events in Node/TypeScript.
Suppose, in my application, I want to have a user purchase a product. When they do so, a Shipping API goes out and creates a label and a WebHook is registered for when the API marks that the package is delivered. Within the next 72 hours, I want the user to rate their item, and if they don't, send a push notification reminding them to when those 72 hours have passed.What is the best way to handle that kind of "eventing" in Node?Thank you.
