What is the best way to simply stream comments from Reddit?
I want to stream comment data from reddit in real time. My problem is this is my first project that I will be trying to update something on the fly as opposed to just sending and receiving request one at a time. If you were to do this what libraries would you use to keep it as simple as possible?

Webpack Aliases with Webpack Merge and Eslint Import Webpack Resolver
Hello everyoneMy eslint doesn't recognize my local modules (webpack aliases). Normally this should be done with the eslint-import-resolver-webpack package but I'm pretty sure it doesn't work because of the way my webpack is build. I'm using webpack merge.. The eslint-webpack-resolver plugin looks for a webpack config file, I feel like it can't read the aliases..Mind you, everything works my project can build. It is just eslint not recognizing my modules.Does anyone have a solution for that?here are the complete files:- https://hastebin.emielvanseveren.be/turanetifo.js (webpack.config.js)- https://hastebin.emielvanseveren.be/icocogibom.js (webpack.parts.js)- https://hastebin.emielvanseveren.be/fonemazado.js (.eslintrc.js)example of the error.eslintrc.jsWebpack aliases (webpack.parts.js)

Move file from external server to AWS
I think that at the beginning I should mention that I'm not using plain node, I'm using nest.js which is based on express but with Typescript.I have an external service which creates audio files for me and return an URL at which I could access the files. After the creation of the file I want to move them over to an AWS S3 Bucket to store them together with other corresponding file. With multer I got it working that when I send a POST request with an file from my local machine to a specific endpoint, the request gets redirected directly to AWS. But I don't found any usefull resources to make the whole thing working with an request made by my server except downloading the file to my servers filesystem and upload it again.Does anyone know a better solution for my problem ?

Knex.js migrations, does each table has its own migration?
Im currently learning Knex.js and try to create a basic todo REST API.I have these SQL tables here``` CREATE TABLE IF NOT EXISTS users ( id INTEGER AUTO_INCREMENT, name VARCHAR(255) NOT NULL, email VARCHAR(255) NOT NULL, role_id INT, PRIMARY KEY(id) );CREATE TABLE IF NOT EXISTS todos ( id INT AUTO_INCREMENT, todo VARCHAR(255) NOT NULL, done BOOLEAN NOT NULL DEFUALT false, FOREIGN KEY (user_id) REFERENCES users(id) ON UPDATE CASCADE ON DELETE CASCADE, PRIMARY KEY(id) ) ENGINE = InnoDB; ```How would I go about implementing them with Knex.js migration? Does each table have its own migration file, like: knex migrate:make create_users and knex migrate:make create_todos or should it only be on a project level like knex migrate:make create_tables?And what if i now have two migration files, would the command knex migrate:latest only take the latest file timestamp based, or include both tables based on the name?

Notifications system using PHP + Socket.io + MySQL
So, I'm looking to implement a notifications system, as well as chat messaging later on into an existing project where the technologies used cannot be changed (as we're quite a bit into development). This is a newbie question as I started looking into this functionality just yesterday.MySQL database contains a table called notifications which gets updated in certain functions in the php controller. I add an entity, other users get notified of it.I've thought about a few approaches:First one I've thought about is listening to the changes of the mysql 'notifications' table... Is this possible? A few online posts say that listen/notify is not possible with mysql. This would be my preferred way of doing this since it seems the easiest and the least complex.The controller function inside php sends data to the node socket and everything gets updated immediately. However, I'm using php phalcon, and I haven't figured out a way yet to do this. I reckon there's an universal php implementation for this maybe, but I haven't found it.Also, I'm open to using something other than socket.io if it gets things done in an optimal way.I'd appreciate help if anyone has run into the same problem! :) Cheers

Sequelize with asynchronous configuration in nodejs
I have been bashing my head for days as I cannot find a valid example of async configuration in Sequelize.So as you may know, you can simply config a Sequelize instance like thatconst sequelize = new Sequelize('postgres://user:pass@example.com:5432/dbname') and then declare your Modelconst User = sequelize.define('User', { // Model attributes are defined here firstName: { type: DataTypes.STRING, allowNull: false }, lastName: { type: DataTypes.STRING // allowNull defaults to true } }, { // Other model options go here }); However what happens when the db credentials comes from an external service?const credentials = await getDbCredentials(); const sequelize = new Sequelize({credentials}) since sequelize models creation are coupled with the instance creation (unlike many others ORMs) this becomes a big problem.My current solution is the following:const Sequelize = require("sequelize"); // Models const { User } = require("./User"); const env = process.env.NODE_ENV || "development"; const db = {}; let sequelize = null; const initSequelize = async () => { if (!sequelize) { let configWithCredentials = {}; if (env === "production") { const credentials = await getDbCredentials(); const { password, username, dbname, engine, host, port } = credentials; configWithCredentials = { username, password, database: dbname, host, port, dialect: engine, operatorsAliases: 0 }; } const config = { development: { // Dev config }, production: configWithCredentials, }; sequelize = new Sequelize(config[env]); sequelize.authenticate().then(() => { console.log("db authenticated") }); }); } db.User = User; db.sequelize = sequelize; db.Sequelize = Sequelize; }; initSequelize().then(() => { console.log("done"); }); module.exports = db; However I feel that this is not a good approach because of the asynchronous nature of the initialization and sometimes the `db` is undefined.Is there a better way to approach this thing?Thanks

Long-running process delaying promises
I have a process that runs for hours, and it has a callback every 1 percent, whose purpose is to send the new percent to the API so that the UI can track the progress.I know the callback is happening because I can see the percentage being console logged.But my promise to send out the new percentage to the API (using axios if that makes a difference) is delayed until the long-running process finishes. All 100 requests to my API go out at the same time, after the long process is completed.What can I do to ensure that my API request is actually sent out instantly, rather than delayed? Here's some pseudo code to clear up any potential confusion.longProcess.start({ onPercent: async percent => { console.log(percent); // I can see this at the right time (one every couple // minutes) await api.updatePercent(percent) console.log('done', percent) // All 100 of these get printed at the same // time. After the entire thing is done. } });

Trying to understand class instances
I am trying to wrap my head around class instances and garbage collection.If I request a row from a database and store its fields in an object in memory, I understand that it makes most sense to use a new instance of a class to for example store user data in a user instance. My question is if I have multiple users using my app at the same time, and I create a user object for every one of them when they log into the site, how do I make sure the variable values in my function don't get overwritten by a new user instance that's using the same code while I'm waiting for an async operation to finish? And if that user object is then not in use anymore, how will the garbage collector now that it is not in use anymore if the code is still referencing that object from certain functions?

I notice it has also updated the top level package.json (the one that belongs to myPackage) with a dependency for React.How do I overcome this?

Building SaaS using node.js
Hi all,I'm trying to figure out the best way to write a SaaS site. The idea is to serve practice tests for qualifying/admissions exams like the MCAT and LSAT.I want to provide a test interface similar to the ones provided by the official companies. As well, I want to integrate code for cursor tracking and custom analytics. I expect that this type of project requires a lot of back-end server work, as well as databases for users, the tests, and their scores.Would node.js be amenable to this type of project? Or would I be better off using something like Python or Django?As you can tell, I'm pretty new to this - are there good resources on node.js specifically, or should I just be extra proficient in Javascript?

Node js and Google sign in
Hi everyone. I've never done any backend development before so I thought asking here would help a lot. Right now I'm working on a project that will use node and angular so I wanted to use google sign for the login and registration to ease my job. But I can't seem to find any concrete resources other than the documentation (https://github.com/googleapis/google-auth-library-nodejs). The deadline is pretty close so would appreciate any help!

NestJS, monoliths and project structure
Hey, I'm currently working on a complete rewrite of an e-learning web app for the company I work for. The first version has been done with pretty much only Express, while all the rest had been implemented without the aid of any framework/library. I wasn't part of the team during the first iteration, and the first problem I noticed when I got hired was the huge amounts of redundant, reused, non standardized chunks of code and patterns.Now that my role is to plan, coordinate and take part in the whole rewriting process and since using NodeJS is the only strict requirement I must fulfill, I'm guessing if NestJS could be the right candidate for the job, given that I've used the framework for some small projects and have gotten to love it, but my mind is filled with doubts and would love if any of you could help me sort some things out.The project is gonna be a big monolith, and this is not even questionable due to a number of reasons I really don't want to waste your time explaining (team size, experience, deadlines, etc..).The modular structure imposed by the NestJS is great to keep things clean, but I can't really imagine how could I "cleanly" get a monolith done with it. Imagine needing 4 subcontrollers (Web, Api, Admin-web, Admin-api) instead of one single controller per module. This would be pretty easy to pull off if modules could be structured in a tree-like form, but all I see in the guides are a bunch of modules existing on the same level, so I guess my best bet would be creating 4 controllers under the same module. Not very clean. NestJS's basic project structure is clearly great if you're going for a SPA on the front (get 1, maybe 2 Api controllers per module and you're done), but what about old-school backend-served Handlebars pages?Also, the courses hosted by the platform should have several activities included, like quizzes, tests, etc.. and they should be freely sortable and configurable by the course admins. I would implement each activity as a different module then have one generic activity module load the right activity-specific module based on a bunch of parameters. Would NestJS be able to handle this kind of dynamic structure?Clearly what I'm trying to find out is if the framework is capable of handling a big amount of deep modularity without going the microservice way or if I should stick to more close-to-the-metal-yet-battle-tested solutions like Express/Koa/Fastify to retain control over the project by implementing my own structural core logic.

video + audio real time chat using socket io in node js
Hi guys,I am trying to do a real-time video + audio chat and I want to use client-server approach not peer to peer (Education purposes). Now I can stream only the video using code bellow. I want to use the same approach to send audio as well to my server using sockets a then emit to all connected sockets. Maybe socket.io-stream library can help if so how can I easily implement it into my code bellow? Or is there a better solution? Thanks.David// client code let socket = io.connect(window.location.origin); const video = document.querySelector('video'); const canvas = document.createElement('canvas'); const ctx = canvas.getContext('2d'); const img = document.querySelector('img'); const audiodata = document.querySelector("audio"); navigator.mediaDevices.getUserMedia({ video : true, audio : true }) .then(function(stream) { video.srcObject = stream; setInterval(function() { canvas.width = video.videoWidth; canvas.height = video.videoHeight; ctx.drawImage(video, 0, 0, canvas.width, canvas.height); const imageData = canvas.toDataURL("image/jpeg", 0.4); socket.emit('sendImage', { image : imageData }); }, 100); }).catch(error => console.error(error)); socket.on("getImage", function(data){ img.src = data.image; }) // server code let express = require("express"); let socket = require("socket.io"); const port = process.env.PORT || 3000 let app = express(); // static files app.use(express.static("public")); let server = app.listen(port, function() { console.debug(`listenning on port ${port}`); }) // socket setup let io = socket(server); io.on("connection", function(socket){ console.debug(`made socket connection with id ${socket.id}`); socket.on("sendImage", function(data){ socket.broadcast.emit("getImage", data); }); });

I made an npm package that helps you distribute your code, allowing you to scale up your applications
Hi! I was recently working on a project and needed to remotely execute something. I solved this by making a small package that would handle this, but realized that by making a few adjustments I could make it an easy tool to use when wanting to distribute your code in a microservice-like way.The premise is simple; you create some servers that can execute functions when requested, then you create a client that will request these functions to be executed. Hook up a load balancer in between them and you’re ready to scale up your appI hope some people will find use in this!The package can be found here: https://www.npmjs.com/package/ezrpc

Understanding the use of process.env in a web app
I was looking at an example React site and somebody used process.env to get a token-like object. This token along with the person's username would then determine whether or not the person could access the site.From reading about process.env it's related to whatever setup/environment the user has on their system. So I was thinking process.env would do something to get the person's relevant token. However when examining the code further there's actually a Config file with a hardcoded token (so I assume it's the same for all users). In this case why use process.env?

Front end, Back end and CAS authentication.
I'm a coop student and I have been tasked with getting a concept up and running with modern technologies. Currently the company has about 10 different applications, 4 or 5 different frameworks, and with the front end and back ends bundled together in each application.In my concept I would like to use an express API back end and a Vue.js front end. Eventually if this works then the plan would be to convert every application to use the same framework. However, the company uses CAS to authenticate everything. Unfortunately, I don't how I would get both the front end and back end to authenticate using CAS.If I was just using a front end and a back end then the front end would send the back end the username and password and validate that. However, the back end doesn't know that information. It has data for each user but knows nothing about their passwords.I do know somewhat how CAS works. And I can get the front end authenticated. But how can I authenticate the back end for a specific user?

I built a website (http://dothyhaveit.com) with which you can check for the inventory of major retailers before your grocery run.
I'm sorry if this is not the right place for it, but I wanted to get the information out. It could be helpful for a lot of people.Hey reddit! Hope y’all are staying safe. I spent the good part of this past week building a website (dothyhaveit.com). It lets you search across major retailers like Walmart, target, etc. and get the inventory for the item you’re looking for. As of now, you’ll be able to search for products in Walmart and Target. The other day, I had to go to a couple of different stores to find a jug milk. This only increases the risk of you getting exposed significantly, and realized it’d be so much better if I could check for it beforehand. Social distancing is how you flatten the curve. With the website, you could see if it available before you go on your grocery run. Visit that one store instead of many. Please feel free to send me a message if you have a question, suggestion, etc. Disclaimer: With Walmart, the stocks are either not updated in real time, or they just don’t maintain it. I’m not certain at this point. The meme section;This is Bill; Bill uses dothyhaveit.com to search for products before he heads out; Bill is smart; Be like bill.

Question about oAuth
Hey guys, I’m trying to make a full stack app right now that utilizes google’s API. It’s MERN stack, and I’m trying to use passport, but i’m confused about how the redirect works. How do I call my express app’s /google route from my react client app, and then get redirected to react client with the token? I’m honestly just kind of flustered right now and would really appreciate an explanation of the flow when there’s a decoupled client app involved! Thank you!!!

Problem testing a promise in a setInterval() with Mocha and Sinon
Hello, I'm having trouble for testing a property in a class which is regularly updated after requesting my database. My class looks like this:class Color { private _green: string = '' private async update() { const greenColor = await API.getGreenColor() this._green = greenColor } private regularUpdate() { setInterval(async() => { await this.update() }, 10000) } public async start() { await this.update() this.regularUpdate() } public get green() { return this._green } } What I've done to test 'start()' and it works:describe('start()', () => { it(`Should set the color`, async() => { sinon.stub(API, 'getGreenColor').resolves('green') const color = new Color() await color.start() expect(color.green).to.eql('green') }) }) Now what I'm doing to test the regular update and it fails:describe('regularUpdate()', () => { it(`Should regularly update the color`, async() => { const clock = sinon.useFakeTimers() const stub = sinon.stub(API, 'getGreenColor') stub.onCall(0).resolves('green') stub.onCall(1).resolves('darkGreen') const color = new Color() await color.start() expect(stub.calledOnce).to.be.true // <-- Passes expect(color.green).to.eql('green') // <-- Passes clock.tick(15000) console.log(color.green) // 'green' expect(stub.calledTwice).to.be.true // <-- Passes expect(color.green).to.eql('darkGreen') // <-- FAILS }) }) So the second call is called with the wrong data? Does anyone know why? I specify that if I use console.log to test "manually", the regular update works.

encountering issue when attempting to run 2 node servers within a single node project?
I've created a new node project in VS Code.I created a single node server file (server.js) in the project and was able to run it by configuring a new child property in the package.json scripts config section.I created a second node server file (authServer.js) in the project and configured an additional child property in the package.json scripts config section.The first node server runs successfully when I npm run its package.json script.The second node server fails when I npm run its package.json script with error "Cannot find module .\index.js."An index.js file was not included in the new project by default. I'm following a demo vid on YouTube which also does not have an index.js file at the root but the YouTube vid example loads up the second server without issueSo it looks like an index.js file or some special config is required when 2 node servers are loaded from the same project.Any idea what I might be missing here or how to fix? Like I mentioned, the example YouTube vid ran the second server from the project without issue without having an index.js file in the project so I'm not sure why my local project is throwing an error?

SocketIO server works fine on Heroku but on Amazon Beanstalk it randomly receives duplicate messages. Why?
I want to move my SocketIO app to Amazon because Heroku randomly restarts it and this is not tolerable.It works, except it receives duplicate messages randomly from the client. Which I assume means the server is sometimes failing to confirm to the client that a message was received, so the client is sending it again.I know this is happening by looking at the logs.It also randomly sends an incomplete portion of a message (or at least, the server receives an incomplete portion of it.Does anyone have any idea where I should begin looking to solve this? How does SocketIO "know" that the environment is different when it's hosted on Amazon to cause this bug?The client is SocketIO-client running on Node, by the way.

Express and Nginx figthing over routing ?
So i have a strange configuration that i need until i get to refactor a project later this year.it is a static index.html landing page served with a location root "/" by NGINX.i have a slash location:```location /channel/ { proxy_pass http://node_server_channel:5000/; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_set_header X-Ssl on; proxy_cache_bypass $http_upgrade; } ```that express.js then handles. Express just serves a static folder with auto-generated content that a user can then navigate around in.It works well in the sense that any appending slashes like:/channel/open/but ONLY if i have a trailing slash after "open". If i leave it out then NGINX will throw a "404 Not Found", if i keep it in, it works as intended.The thing is that a user should be able to click on a folder in the static served directory to traverse a file structure, and the way that works in a browser is that it does not append a trailing slash to a directory name when clicked, so NGINX then throws the "404".I have tried a NPM package called 'express-slash' but that did not solve the issue.i was hoping someone here had some suggestions on what i could try out next?

Help with a quick issue. Making an http request from one express server to another but the request keeps getting refused. Anyone know why this might happen?
As I said in the title, I just have one server making a request to another server to get some information. It's not a cors issue because I'm accepting all request in my dev environment, plus the front end server can make requests to it just fine, as can I from the node repl using the same code. This is probably the first issue I've had where I'm at a complete loss about why it's happening. I'm using axios to make the request and all I get back is this:Error: connect ECONNREFUSED 127.0.0.1:9000 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1113:14) Desperate for help with this, it's been driving me crazy.

Create a nodejs function to take parameters and post them to a url like form-data

I have almost completed everything but the problem is I can't figure out how to redirect the req such that it also POST's the parameters and what to return in that case.My basic question is that if we handle a request and my method is being used then what should I return in my method definition and what should I write after my req.const mylib = require('mylib'); app.get('/', (req,res)=>{ mylib.createTransaction(txnId, amount, firstName redirectUrl, hash,function(error, response, context) { //what should I write here or in my method definition to redirect this req to a URL and end not await for res. }); });

Want to learn back end
Hello,I know there are many resources out there and have looked at the wiki/other guides, but I have some more specific preferences/situation that I'm hoping you guys can help me out with.I have zero experience in web dev or programming and I'm trying to build a (mechanically very simple) multiplayer game with not more than 10 players. I've been learning HTML/CSS/JS for two weeks and have some ability to write algorithms, as well as have set up very basic interactive web pages, but no knowledge of back end or how to handle the data, send and receive it via web sockets or anything. Whenever I search up 'learn back end' or 'learn node/express' all the top answers say to just start writing code - I would love to do this and already have my project in mind, the reason I'm learning all of this, but I physically don't know how to begin. Lots of resources assume prior knowledge of web dev principles/other back end languages and frameworks, which I don't have.I can't learn from videos at all, which is a major reason why I'm asking here. I learn best from written resources. Can anyone recommend written resources for absolute beginners on back end, taught using Node/Express?Thanks for your help.

I was recommended SuperTokens for Auth in Reddit comment section, So happy!
As a Junior Dev, Auth is hard. I couldn't find much online explaining how to have a secure authentication system for my app other than the quick-start JWT guides or Auth0. At one point having 30+ tabs to try and understand this shiz. Long story short Auth0 ≠ Oauth. Heh. So after talking on Reddit, I was recommended a product (It's open source) here in the comment section.I found SuperTokens! it took me 1 day to implement and can now peacefully delete all my tabs. And I am loving it! It uses Cookies that contain an access token which expire and must be refreshed with a refresh token. It can detect intrusions and provides more protection than I could have if I'd done it myself. Didn't bother trying it until looking online for a month and giving up.https://preview.redd.it/q1rwrmdx80p41.png?width=1682&format=png&auto=webp&s=46b2269011225a4d563f7265514def8f54a81561Had to post here to show gratitude as one of their team screenshared to answer some of my questions on how it works. And this is what I've understood:How it works:Using a stack of your choice (currently Node + MySql/Postgres) you find in the docs that you need the CLI, to start the process daemon, an Init() function in your app providing the port for the Auth service and then must create the necessary DB and tables. DB for example called auth_db, with 3 tables, key_value, which has the rotating signing access key (for access token) this is automatically generated and rotated. The past_tokens table and a sessions table that contains all user sessions currently logged in.To implement in your code, you call createSession(...args) at /login, this returns a Response with headers that contains all of the cookie/token information. Next you'll have middleware (if using express) that checks the cookies on every api request. And if this fails you have a /refreshSession (or whatever) endpoint for creating a new session for a user that's already logged in. So first Login (/login), then Middleware, then Refresh (/refreshSession).The docs explain how to log users out, destroying their sessions and error handling for detecting breaches And all of this info has useful examples.It all works smoothly and one thing I didn't really understand but now do and want to share just incase is that: all of this is tested in insomnia/postman via passing correct headers and cookies with each request. But all of the cookie management and header management is handled on the front-end automatically via the front-end SDK they've built (ios/android/web).My opinion is that this is a great solution in comparison to the lock-in options like Firebase, Auth0. Which have benefits in their own ways but this takes the cake for me. With very-little set up. Smooth transition between free (community + opensource) and pro (paid but less than $300 a year). And some really nice security features. Blacklisting, session revoking, refresh & rotate, anti-CSRF. Anti XSS.I'm using this because I reason that it is a dedicated solution and probably better than what I can create myself. Easy to set up and I've never seen something that I actually trusted a little.So here's the Docs,Cheers

Need help with map website with node backend
IDK if this is the place for my request but here I go.I have a small university project where we need to develop a mapping website similar to mask.goodideas-studio.com but for Hong Kong, instead of Taiwan. This website is based on data from the government but our version is crowdsourced. The API for it has already been developed but we need developers who can help implement it.Honesty time: there is no pay but it is for a good cause imo.Reply or PM if you're interested in helping or maybe guide me to someone who you think can help.Thanks.

Backpressure problem in http.ServerResponse
Hi guys, I'm new to Node so I'm practicing some backend development using only pure Node (no frameworks) to get a feel for it, and I thought I'd give streams a try to process a somewhat large text file (a 200 MB .txt file).I think I have a backpressure problem in my code and I'm not sure how to solve it. Here's the code:// The default chunk size of Streams created by createReadStream is 64kb, which // is far too small for big files. This CHUNKSIZE is set to 1 MB const CHUNKSIZE = 1048576; const server = http.createServer((req, res) => { if(req.url == "/") { // The following hack doesn't seem to work //res.socket._writableState.highWaterMark = CHUNKSIZE; const stream = fs.createReadStream(__dirname + FILENAME, {highWaterMark: CHUNKSIZE}); // outputs "16384", as expected. If I uncomment the hack above, it does // show CHUNKSIZE, but still doesn't seem to work console.log("res.writableHighWaterMark: " + res.writableHighWaterMark); let fileChunkNum = 1; stream.on("data", (chunk) => { console.log("\nFile stream received chunk #" + fileChunkNum++); console.log("Megabytes read so far: " + (stream.bytesRead / 1024 / 1024) + " MB"); }); // FIXME: I guess this is taking forever because of res' default highWaterMark (16kb) stream.pipe(res); } else { res.end("Request not handled"); } }); Now, I've been reading about Streams and the problem here seems to be that there's no way to set the highWaterMark of an already created Stream (in this case, the http.ServerResponse that createServer passes as the second argument to my callback). I've tried to hack around it by manually setting the highWaterMark of the ServerResponse's socket's _writableState but that doesn't seem to work (even though the correct value is displayed when I console.log it). If I remove the call to stream.pipe, the chunks are very quickly logged in the console, so I guess what's happening is that res' paltry 16kb buffer is getting overwhelmed. Is there a solution I am not seeing? Is my whole approach just completely wrong? I'm open to any suggestions.

Using node for server-side machine learning
So, I am planning on a client uploading some data to the server and the server doing some machine learning regression and returning the result to the user.I heard Node.js is not very efficient at doing such things due to it's single-threaded nature.Is it possible to do this machine learning on the server end with potentially hundreds of clients? Or, will another server side language like PHP or Python's libraries be a better choice?

4 possible reasons why your Docker containers can’t talk to each other
When you put a NodeJS application in a container, something that often breaks is the connection to the database and other services. If you're struggling to get two containers to talk to each other, you can try these 4 troubleshooting steps to quickly fix your issue. In short:Containers should be in the same networkConnecting to a container by its name isn't possible in the default network, create on of your own insteadMake sure you are using the correct IP addressThe network should have ICC enabled (it does by default)In the article, I elaborate a little bit more on each bullet point and show you a solution. This isn't a comprehensive list, but hopefully it helps some folks who have already spent several hours debugging their issues.

Node.js for ecommerce?
Hello everyone!I am thinking about using nodejs to develop an ecommerce site. It's nothing big: maybe 50 products maximum and no special features. I've found a lot of posts claiming that nodejs is unfit for ecommerce because it's not mature enough yet or it is not fit to use together with relational databases, etc. So what do you think? Is there a lack of ecommerce tools/plugins to build a complete functional and secure ecommerce site? And is there really an issue using nodejs together with relational databases? In general, Is nodejs a less appropriate alternative for ecommerce than let's say Django or Wocommerce? If that's the case, then why?All thoughts and ideas are highly appreciated!

Problem debugging Node.js application in WebStorm
Hello,I'm completely new to Node.js, coming over from c++. I'm trying to make a module for an existing node.js application. Essentially I'm just writing a function to parse a text file with a specific format. I can't set up the parent application in Webstorm so I tried just make a simple html file to call a script, which then calls my module. However, while my script seems to be launched, my module doesn't get called. My code looks as follows:E:\Productivity\WebStorm 2019.3.4\Projects\mysettingsparser\Caller.html
Title
E:\Productivity\WebStorm 2019.3.4\Projects\mysettingsparser\index.jslet patcherPath = "S:\\ParentScript\\Modules\\MyModule"; let settingsLoader = require('E:\\Productivity\\WebStorm 2019.3.4\\Projects\\mysettingsparser\\settingsLoader.js'); function go() { document.write("hello!"); document.write(settingsLoader.testfunction()); settingsLoader.loadPackSettings(patcherPath); } E:\Productivity\WebStorm 2019.3.4\Projects\mysettingsparser\settingsLoader.jsmodule.exports = { testfunction: function() { return "Testing!"; }, loadPackSettings: function(patcherPath) { document.write("Loading!"); let fs = require('fs'); let resourcePath = patcherPath + '\\ResourcePackSettings\\'; // path to resource pack files // look in path and pull candidate files let returnstring = ""; let files = fs.readdirSync(resourcePath); let groupAndFileNames = []; // names of groups in text file for (i = 0; i < files.length; i++) { groupAndFileNames = validatePackSettings(resourcePath, files[i]); for (j = 0; j < groupAndFileNames.length; j++) // go through each group name { returnstring += groupAndFileNames[j][0] + " (" + groupAndFileNames[j][1] + ")"; } } return returnstring; } }; //ValidatePackSettings is defined here but irrelevant (I think) to my problem When I open the html in WebStorm, launch it through Internet Explorer, and click "Start loader", I get the message "hello!" displayed, but then nothing happens (it doesn't call testfunction() and display "Testing!"). I tried setting breakpoints at every line in index.js but when I click debug in Webstorm, it breaks at let PatcherPath, then let settingsLoader, and then it skips all the way to the closing } of the go() function. I think that the overall syntax is correct because WebStorm's autocomplete function recognizes both testfunction() and loadPackSettings(patcherPath) when I call them from index.js.It seems to me that I'm misconfiguring something - the debugger isn't listening to the html file, and then for some reason it skips over my go function even though the first part of go() works because I get "hello!" on my html page.If someone could give me a hint, I'd really appreciate it!

Can you add an overlay menu using Express?
I'm currently taking Colt Steele's web dev bootcamp. I've been coding along with it, but I didn't want a carbon copy of what he's done, so I learned a lot more about CSS and DOM manipulation on the side to keep things interesting. I know how to do an overlay menu normally. I have one started on the landing page already. But now I'm trying to implement it into authentication. I'm just learning authentication now, and am using Passport as an extension. What I'm trying to do is make it so that a user can only make a post if they log in. I know how to set it up where it just redirects you to the login page and once you log in it works fine. but what i want is for a menu to come up when you click the button that says you need to be logged in to comment and it gives you the option to login, sign up, and exit. the thing is, i don't know how to do that where it only does that when you're not logged in. once logged in I want to be able to click the submit button and be redirected to the comment posting page, but currently the menu just pops up every time, and when i try other changes, then the menu doesn't pop up and it just goes straight to the post page. not sure if this is totally clear so i have the snippet of code im trying to fix.function isLoggedIn(req, res, next) {if (req.isAuthenticated()) {return next(); }res.redirect('/login');}so instead of redirecting to the login page, i want it to bring up the menu where i can click login and be taken there. i know it's not necessary, but i'm trying to make things more creative and by doing this im ultimately learning more than just coding along and not making changes. thanks in advance. sorry for not being articulate enough, i'm new to this so trying to explain it isn't the easiest, especially since i don't always know what i'm doing...

Just finished a Node course. Need help.
Hi peopleI have just finished a node course and yes I learned a lot. However it was a lot of information and it is normal to feel a bit overwhelmed straight after finishing a course. Please allow me to ask a few questions that I have:I learned a lot about authentication. My question is simple, how does backend auth relate to frontend auth? They both have auth aspects, I always thought auth was done in backend, but these days I see auth being done in frontend, how exactly do they relate?Perhaps a weird question, but would someone be able to summarize only the most absolute fundamentals to creating a backend app? For React, for example I already know that, which is to create-react-app, etc. But with backend, you start with npm init, then creating a src folder, index.js folder, that is it, correct?Connected to question 2, database. This makes things confusing also, the course that I learned form used a ton of tools which makes everything confusing - from robo 3t, to downloading mongodb, to using mongoose, to using mongodb atlas, to using mongodb compass. Wow this is all so confusing.TL DR: Basically, could someone please answer question 1, and summarize in the most basic, fundamental way, the steps needed to start and deploy a backend.Thank you all!

When I exit Visual Studio Code and relaunch it, app seems to run just fine! Really hard to debug; try looking up on web, but can't wrap my head around the solutions there. Is it just some problem I'm facing, or something you've also experienced?Also, sorry if you're unfamiliar with the particular course, but from what I understand; his courses are some of the most practiced ones for basic NodeJs beginners, hence I directly refer to them.

Problem accessing the page while using puppeteer connection

I have opened the chrome with debugging mode, received the ws url of the chrome page I am in, and connected successfully. Here is the connection code://open library const puppeteer = require('puppeteer'); //connect to excisting open page async function connectToChrome() { //Connect to excisting browser const wsChromeEndpointurl = 'ws://127.0.0.1:9222/devtools/page/5D6126455A889AA7D17B66C10729F352'; const browser = await puppeteer.connect ({ browserWSEndpoint: wsChromeEndpointurl }); The page which I have connected to is inside a url of a youtube video. My code's purpose is to find the amount of views of the video I am currently watching and log it to the console. When I have used this code while opening a new browser it was very easy, but now that I have connected to an existing page I don't really understand what is going on. I am not exactly sure how to access the information that is in the page, in a normal browser open you just open a new page, go to url, and save it to a variation. But right now I have no idea on which variation to call .$(xpath) to find the element//open library const puppeteer = require('puppeteer'); //connect to excisting open page async function connectToChrome() { //Connect to excisting browser const wsChromeEndpointurl = 'ws://127.0.0.1:9222/devtools/page/5D6126455A889AA7D17B66C10729F352'; const browser = await puppeteer.connect ({ browserWSEndpoint: wsChromeEndpointurl }); const [el] = await browser.page.$x('//*[@id="count"]/yt-view-count-renderer/span[1]'); const txt = await el.getProperty('textContent'); const txtJson = await txt.jsonValue(); console.log(txtJson); }; connectToChrome(); This code will return not understand the following line sentence, as it is undefined:browser.page.$x What would be the right syntax to access this element?

Crypto.createHmac not properly encoding
Hello, I'm trying to replicate one of my Python3 files in nodeJS but im finding my createHmac is not returning the same encryption hash for the same secret and message as the pythons hashlib. Is this stackoverflow post inaccurate when it says that they are syntactically the same for the sha256 encryption? Below are my encryption codes.Node JSconst Crypto = require('crypto') // Standard JavaScript cryptography library signData = Crypto.createHmac('sha256', secret).update(message).digest('hex') Pythonimport hashlib hash = hmac.new(secret, message, digestmod=hashlib.sha256) signData = hash.digest().hex()
