Hi, so I just installed Node in windows which also installed Python 2.7 along with other needed build tools. I wanted to use Python 3 in Windows and was installing Python 3 ( Anaconda ), but on doing so it is causing conflict. Because even on renaming Python2.exe and Python3.exe the pip file still has same name and many other scripts/executable.I usually use cmd and VS Code and don't have much use of Python 2 other than for Node / NPM.Any suggestions ?

Can someone translate this very simple rails code to node?
I am trying to verify an iOS app receipt using Firebase cloud functions, which uses node. Have previously done this in rails and it was quite simple, but I've searched for how to do it in node, and as expected with JS there are 10000 different ways, and as a non-js/node dev, it is extraordinarily confusing. Here is the rails code:def verifyReceipt begin uri = URI('https://buy.itunes.apple.com/verifyReceipt') http = Net::HTTP.new(uri.host, uri.port) http.use_ssl = true req = Net::HTTP::Post.new(uri.path, {'Content-Type' =>'application/json'}) req.body = {"receipt-data" => params[:receiptData]}.to_json res = http.request(req) render json: res.body rescue => e render json: { error: e } end end So far, this is my node code:exports.verifyReceipt = functions.https.onCall((req, response) => { const receipt = req.query.receiptData; options = { method: 'POST', url: 'https://sandbox.itunes.apple.com/verifyReceipt', body: ({ "receipt-data" : receipt, }), json: true }; var req = https.request(options, function(res) { // I understand I need to wait for the request to actually call Apple's server here...but how do I get the response as JSON here and then send it back to my app? }); req.end(); }); thanks.

Need help with deciding the microservice architecture
Hi,This is a first time I’m implementing microservices myself. Did anyone from you have done this kind of setup?https://preview.redd.it/7cv5xx64tx141.png?width=685&format=png&auto=webp&s=0a59736aadc9393d2ce4b1e87ddba6d0c170228dThe application tier includes API gateway and the services who talk to databases.All the services are containerised Node.js servers and also acts as GRPC servers.The API gateway here is Node.js process that will convert REST requests into RPC to the target service.I'm also thinking of using Apache Kafka as message queue.I'd love to get some insight from you guys.

Need help on authentication architecture
Our team is building a small system in Node.js, and we're having a good time with Express and Sequelize so far. We're going to need an authentication solution in the next couple of months, though, and that's kind of worrying me right now. None of us have much experience with authentication in general. We've learned a couple of things about it in the Internet, but there are still important missing pieces in this puzzle.Seeing as this new server (let's call it Server A) will share the same user database with another already established service running in the company (Server B), we thought they'd simply grant us access to this database in order to authenticate the users through Passport.js. They suggested doing something else entirely, to our surprise.The suggestion goes as follows: the users will log in through Server B and be redirected to our new server by clicking a specific link in their user page. Server A would then receive a request from Server B with a special token containing some data about the authenticated user (email, resources he is authorized to read and edit, and so on), and take it from there. This way, Server A wouldn't need to query the user database in production and all authentication would remain entirely in Server B. We wouldn't even need to worry about HTTPS in Server A: once the user authenticates in Server B via HTTPS and their useful data are transferred to Server A, they wouldn't need to maintain a secure channel with Server A after that.The main questions here are:1- Is this architecture really feasible? Would we really be able to avoid using HTTPS in Server A if the authentication part is only used in Server B?2- How would Express support this? In theory, they think we could achieve this by only treating the requests to the Server A home page, by checking if they come from Server B, and then proceeding to store the data received in a session or JWT token. Is it really that simple? How would Server A understand that the request from Server B is just an information to be used in a connection with another client? Would Passport.js be able to handle this situation somehow?3- Would you use sessions or JWTs for this job?4- Would we run into immediate CSRF problems or at the very least risk both servers this way?5- Should I insist on the shared database solution, considering we just need a read-only access on it and it'll probably make things easier? I mean, we would only need to construct get/post routes for login and implement their logic, basically. The only extra challenge I can see with this approach is incorporating SSL/TLS in our service, something that's not part of the initial scope, but I feel it might probably be both more critical and easier to implement than I thought.Any help is appreciated. Thank you all in advance!

Promises and the FileSystem
So I'm currently working on a bot to do some Reddit moderation. I typically do db work and stay away from the file system so I believe I might be doing something wrong here.Essentially, the code below declares two variables from the returned values of an async call.// Check for previous contact. let [final_list, add_to_db] = await checkForContact(needs_comments, db); final_list.map(post => { console.log(post); fs.writeFileSync('./stuff.txt', `${post}\r\n`, { flag: 'a' }); }); final_list is an array of Promises that are set to be fulfilled by Promise.all() within the function. Upon returning here, the data should be written to a file. While it does write to the file, it only writes [object Promise] on each line.Am I missing something with the async call here?

New to Node and need a little help/information.
Hey, yesterday I was bored and decided to make a little project.The plaan was that you can go on my website which is hosted on my pc see a textbox in which you can enter a text when you press submit the text will be repeated as Text to Speech from my computer (just a little "nonsense" prject to learn some new stuff). The Text to Speech part is what brought me to NodeJs so I started learning a little bit of the syntax and behavior of NodeJs. Now I have a problem I expected that i could execute a NodeJs file similar to an PHP file enbedded into an HTML script but after some research i could not find an easy answer on how to execute a NodeJS file after clicking a button on a webpage. So my question is how to do that if it is even possible (I just could not find anything in that direction). I am using WampServer to host the Webpage.Thanks in advance!

Anyone know of a way to profile why nodemon app restart (using webpack build/watcher) takes long sometimes?
Have an app that recompiles on any backend code change (using webpack watcher). The webpack bundling is fast, but then nodemon takes notice of the build change, and tries to restart, but it sometimes takes a while (10+ seconds). Not only that, it will also restart several times on its own during this process, without a file change, ie:[nodemon] app crashed - waiting for file changes before starting... [nodemon] restarting due to changes... [nodemon] starting node build/api.js [nodemon] restarting due to changes... [nodemon] starting node build/api.js [nodemon] restarting due to changes... [nodemon] starting node build/api.js API server listening on http://localhost:3000 Is anyone familiar with this happening, or might have advice for profiling why nodemon is taking a while, or maybe there is a better process manager or something? I've tried pm2 before, will give it another go...I'm a pretty seasoned developer, and have used node a while, but at this point, it's become a headache a lot, with stuff like this, and recently the app sometimes won't even respond to requests. Just sits there saying it's running, but backend doesn't respond (fetch requests stay pending). Restarted the app several times successfully, but didn't help. I had to restart the computer for it to get back to working. Sometimes it does this because of invalid backend code (for instance I once accidentally had new DateTime() instead of new Date()), and it couldn't detect this at all and produced no error, but the server would just hang. Considering just moving to Java or even PHP again.

Express + PythonShell - first request is always the slowest
Hi All,I`d like to raise a question in case somebody is familiar with this or has an idea.I`ve created an API using ExpressJS and for some POST routes, I`m using Python-Shell to call some scripts which takes the body from the POST request to do something with the data.A really weird thing that I am notificing is that whenever I am sending a request to these routes which call Python scripts (could be more than 1), the first request always takes the longest, then the more I use the route (send requests) the faster the reponse is received.It feels like the API is in an idle state, then 1st request comes in, it takes a while, then it`s getting used to getting calls to this route and behaves faster and faster. Latest test, 1st request takes 3 seconds, then 1s, then below 1s etc. etc.I`m thinking it might have something to do with the runtime of the scripts and spawning processes the call these scriptsEdit: inside the POST route, I have created a method which return a Promise with the results from the python script.Something likeexampleMethod : (json, pythonPath, pythonScript) => {return new Promise( (resolve, reject) => {let options = {mode: 'text',pythonPath: pythonPath,pythonOptions: ['-u'], // get print results in real-timeargs: [json] //json is data received in the body of the POST};// Here I call the Python scriptconst pyshell = PythonShell.run(globalPath + pythonScript, options, (err, results) => {if (err) {console.log('Error');console.log(err);reject(err);}});pyshell.stdout.on('data', function(data) {// console.log('Data: ',data);resolve(data);});pyshell.end();});}Then in the POST request, I am calling the exampleMethod().then() to get async the results and continue the logic.Many thanks!

Confusion about duplex streams
I'm working on a data-sink of sorts that is eventually to be used for Key-Value object streams in nodejs.I've stumbled across duplex streams and started playing with them a bit to get my feet wet, but everything I try seems to not work.At present, I've got this duplex stream:``` class StorageStream extends stream.Duplex { constructor() { super({ objectMode: true })this.values = new Map(); this.entries = this.values.entries(); }_write(data, encoding, next) { const { key, value } = data;this.values.set(key, value); next(); }_read() { const next = this.entries.next();if (next.value) { this.push(next.value); } } } ```This is a SUPER CONTRIVED example, but essentially, when I write to this stream it should store the key and value in the Map, and when I read from this stream it should start reading from the map and passing them down the stream. However, this doesn't work, doing basically the below``` const kvstream = createKVStreamSomeHow(); // a basic, readable stream with KV Pairsconst logger = createLoggerStreamSomeHow(); // writable stream, logs the data coming throughconst storage = new StorageStream();kvstream.pipe(storage).pipe(logger); ```causes the process to just end. So I guess I'm just a bit confused as to what I'm supposed to be doing inside of the _read method.

Heroku filesystem restart
Hello,I want to deploy my node application on a free hosting service as I want to show it to a company to land a job.Now, in this application the user can add products and upload images of the product.On heroku, everyday the filesystem gets restarted, this deletes all the images. Also, when an error occurs the filesystem gets deleted.It's recommended to store all files on AWS S3. This seems like quite some work because I have to make many changes in the codebase and I need to have the application ready by tomorrow.Are there other ways of getting around this problem?

How Node.js can help you maximize IoT productivity
Ever since Node.JS came into existence, it has become popular among various developers across the world in making APIs and constructing new matrices that are utilized on the internet. Node is a highly powerful tool, but that doesn’t mean it is perfect for every project. Before you get in touch with a reputed node.js development company, know why you want to utilize this platform in the first place. If you’re handling a big project with a broader scope, it is better to settle for Node.JS as it is a great choice.Node.js Provides an Easy ScalabilityOne of the prime benefits of Node.JS is that developers find it quite easy to scale the applications in horizontal and vertical directions. The applications can be scaled in a horizontal way adding extra nodes to the existing system.Furthermore, Node.JS also provides you with the option of putting additional resources to the single nodes during the vertical scaling of the application. So, it is extremely scalable and gives a much better option compared to other JavaScrip servers.Hire node.js developers to help in adding convergence of efficiency and functionality as per your business needs.Role of Node.JS DevelopersAs Node.JS is evolving technology, it is a hot skill possessed by any developer for the instant and near future of modern web application development. A perfect understanding of Node.JS will assist you in utilizing JavaScript to expand real-time, quick, scalable, data-driven web applications.It also permits you to rapidly adapt to any of the appearing, cutting-edge JavaScript technologies. As Node.Js core and its applications are broadly divided into modules, they are shared and well-composed. All the tools and packages are well-crafted and scooped tightly into manageable parts that are baked together.Get in touch with a trusted node.js development company and acquire reliable and suitable solutions for your business.Maximize IoT productivity with Node.JSThinking about why Node.js is a perfect and natural fit for IoT applications is understandable. To leverage technology to activate business expansion, you need to keep an eye on technological growth as well. It is the prime way of how big firms are evolving by recognizing the next ‘big thing’.To withstand the hurdles and achieve smoother flow in a business, sooner or later, all companies need to obtain data management tools, intelligent solutions, and excellent network control. IoT is all about linked and synchronized environments across various systems that consist of the integration of microservices, wireless technology, web, devices, and sensors.The prime purpose of utilizing Node.Js in IoT applications is the quicker and real-time execution. On the server-side, it also engages less memory and results in an effortless performance. Hire node.js developers and obtain great support of low-source needs and APIs.

Need help with deploying Node apps with K8s
Hi,I'm using GitLab and working on a rather large project. My repository is a monorepo that contains several packages, some dependent on others.Previously I would set up my CI/CD on a single runner with shell access sl that my projects would be deployed properly, however, I want to scale up and figured using Docker would help, as well as not having to micromanage Node.js versions.Is there anyone here with a properly set up Docker / K8s CI/CD pipeline specifically for Node.js? I'd love to get some information on where to start or articles that dumb it down a slight bit.

Beginner learn the correct way of module.exports and global variables
What I get from most of the answers I could find is we should not use global variable lightly.Using NodeJS, we can use module.exports and then require in files that are needed.What I would like to know is would the variable get initialize again on multiple require ?For example on database connection using Sequelize:let sequelize = new Sequelize(...) module.exports = sequelize If file1.js require, it will then creates connection to database.What happens on other files that require it later on? Will it initialize connection again? If so, how do I make it like Singleton?Sorry if this has been asked before or my understanding is wrong.Thank you in advance.

Node.js hardware suggestion AMD or INTEL ?
Hey I am looking to buy a new hardware for my nodes.js server and atm I am stuck on which cpu to buy? My system is meant for a multiplayer game with lots of computation so all the x, y (2d) stuff includes angle calculation distance calculation with square function etc. Also there is a lot of chunking of arrays down for each client.Currently I have a Intel Pentium N3710 quad core Synology System DS916+ MariaDb and Iam programming only single threaded so my target would be a good single thread cpu . For future targets I also want to have multi core .Future setup would be my nas for myself a good nodes.server(good cpu) and some raspberry pi for the little stuff like Mysql which runs for backing up stuff.My question would be for which benchmark should I look for when comparing the different cpus to be able to fulfill my needs also should I look for fast ram due to from what I understood nodes runs in a event loop ?Would be nice to get some good feedback

No TCP or TLS handshake happening in the https.request() call?
Here is the client code I am working with:var options = { hostname: "my host", port: 8080, path: '/', method: 'GET', key: fs.readFileSync('clients key'), cert: fs.readFileSync('client cert'), ca: fs.readFileSync('CA cert'), rejectUnauthorized: false, }; // code to get current time var req = https.request(options, function(res) { res.on('data', function(data) { process.stdout.write(data); }); }); // code to get end time and thus calculate total time of transaction. But end == start time! req.end(); Here is the server codevar options = { key: fs.readFileSync('server key'), cert: fs.readFileSync('server cert'), ca: fs.readFileSync('CA cert'), requestCert: true, rejectUnauthorized: false }; https.createServer(options, function (req, res) { res.writeHead(200); res.end("Hello client" + "\n"); }).listen(8080, "host"); So right now I can successfully make a GET request from my client to my HTTPS server (haven't actually added in a resource to retrieve yet). The thing is, when I print out the time for the client to make the http.request() and the time it finishes (both in ms), they are the same! The connection between my client and server has an inherent baseline 5ms delay which clearly shows something is wrong, as my start time == my end time (where as my end time should be ~10ms more than my start time).My first guess is that I need to manually perform a TCP handshake and/or a TLS handshake, although I assumed that would be done under the covers by http.request(). Am I missing something here? Do I need to be doing something else to perform a handshake? Thanks!

Everything is working wonderfully, but the issue I am having is when someone access the New User page and submits their info to the database, I am trying to send an email that will give the new user an authentication number they have to submit. But every change I make to my code with nodemailer, it won't send the email. The data is still submitted to the server, just no email is sent.My portion of the code that I am trying to work on:var transporter = nodemailer.createTransport({host: "smtp-mail.outlook.com",port: 587,secureConnection: false,secure: true,ignoreTLS: false,requireTLS: true,auth: {user: 'user',pass: 'pass'},tls: {ciphers: 'SSLv3'}});var mailOptions = {from: 'user',to: email,subject: 'Please Verify Your Account!',text: authenticationNumber};transporter.sendMail(mailOptions, function(err, info) {if(err) {console.log(err);} else {console.log(info.response);}});The error I am getting is this:[Error: 3408:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:c:\ws\deps\openssl\openssl\ssl\record\ssl3_record.c:332:] {library: 'SSL routines',function: 'ssl3_get_record',reason: 'wrong version number',code: 'ESOCKET',command: 'CONN'}I have tried looking on Google and anywhere I can find to solve this issue, but I haven't been able to find anything for the past 2 weeks.

Node.js performance issue?
I was making some benchmarks on Node.js and I found something interesting: a potential performance issue.Try running this piece of code with Node (do not try to run it on the browser since it seems there are no problems with javascript on the browser):function benchmark(nrOfTimesToRun, fn) { const startTime = +new Date(); for (let i = 0; i < nrOfTimesToRun; i++) { fn(); } return +new Date - startTime; } class Property{ static get(target) { return target[this.KEY]; } } class NameProperty extends Property{} NameProperty.KEY = 'name'; class RoleProperty extends Property{} RoleProperty.KEY = 'role'; class User {} var user = new User NameProperty.get(user); // RoleProperty.get(user); const result = benchmark(1e7, () => { NameProperty.get(user); }); console.log('Execution time: %d ms', result); In my case, Node completed the task in `77 ms`. Now uncomment the `RoleProperty.get(user);` line and run the code again.BOOM. My pc finished the task in `1162 ms`.What is the problem here? Why it is taking so slow to run the benchmark in the second case?Debugging this I found that `return target[this.KEY];` might be the problem. More exactly `this.KEY`. I think Node has a hard time getting the static property.Is this a known problem of Node?

I therefore want to run npm install --only=production in that directory, in order to strip off "junk" not needed in node_modules.What I have tried:Using an npm-command in Gruntfile, with this config:'npm-command': {npmInstallDist: {cwd: "./dist/",cmd: "install",args: ["--only=production"]}},This does not work, it seems like it ignores the cwd completely, and do the work in the root node_modules folder.I then tried to add a script in package.json:"scripts": {"buildDist": "cd dist && npm install --only=production"}This does not work either, not sure exactly why. It still remains in the root directory when installing.So, I'm stuck.

Show image
I get a random name from the array but at the time of displaying the images it fails and it puts me that it is not a file or directory, the js file is in the same folder as the images to prevent me from getting the name with the path, in another version that I have with the route if I get both the image and the corresponding name but with the route as well and I want to avoid showing that route, I have already avoided it with the extension but I don't know what else to try.-- 1st version (js in the same folder where the images)const Discord = require("discord.js");const config = require("../config.json");const colours = require("../colours.json");const window = require("window");const randomFile = require('random-file');const path = require('path');const fs = require('fs');module.exports.run = async(client, message, args) => {const randomimg = ["Aegiochusmon Blue.jpg","Aegiochusmon Dark.jpg","Aegiochusmon Green.jpg","Aegiochusmon Holy.jpg","Aegiochusmon.jpg","Aegisdramon.jpg","AeroVeedramon.jpg","Agumon (2006 anime).jpg","Agumon Burst Mode.png","Agumon Expert.jpg","Agumon X.jpg","Agumon.png","Agunimon.jpg","Aircraft Carrier Whamon.jpg","Airdramon.jpg","Akatorimon.jpg","Aldamon.jpg","Allomon.jpg","Allomon X.jpg","Alphamon.jpg","Alphamon Ouryuken.jpg","Amon.jpg","AncientBeetlemon.jpg","AncientGarurumon.jpg","AncientGreymon.jpg","AncientKazemon.jpg","AncientMegatheriummon.jpg","AncientMermaidmon.jpg","AncientSphinxmon.jpg","AncientTroiamon.jpg","AncientVolcanomon.jpg","AncientWisemon.jpg","Andromon.jpg","Angemon.jpg","Angewomon X.jpg","Angewomon.jpg"]const img = randomimg[Math.floor(Math.random() * randomimg.length - 1 + 1)]message.channel.send({file: img})message.channel.send("El digimon es: " + img.replace(/\.[^.$]+$/, ''));}module.exports.config = {name: "digimons",usage: "-digimons",aliases: ["dig", "digimdesc"]}In this case it shows me the name without the path or extension (just as I would like) but does not show the image.-- 2nd version (js on a different route from where the images are)const Discord = require("discord.js");const config = require("../config.json");const colours = require("../colours.json");const window = require("window");const randomFile = require('random-file');const path = require('path');const fs = require('fs');module.exports.run = async(client, message, args) => {const randomimg = ["./Digimons/Aegiochusmon Blue.jpg","./Digimons/Aegiochusmon Dark.jpg","./Digimons/Aegiochusmon Green.jpg","./Digimons/Aegiochusmon Holy.jpg","./Digimons/Aegiochusmon.jpg","./Digimons/Aegisdramon.jpg""./Digimons/AeroVeedramon.jpg","./Digimons/Agumon (2006 anime).jpg","./Digimons/Agumon Burst Mode.png","./Digimons/Agumon Expert.jpg","./Digimons/Agumon X.jpg","./Digimons/Agumon.png","./Digimons/Agunimon.jpg","./Digimons/Aircraft Carrier Whamon.jpg","./Digimons/Airdramon.jpg","./Digimons/Akatorimon.jpg","./Digimons/Aldamon.jpg","./Digimons/Allomon.jpg","./Digimons/Allomon X.jpg","./Digimons/Alphamon.jpg","./Digimons/Alphamon Ouryuken.jpg","./Digimons/Amon.jpg","./Digimons/AncientBeetlemon.jpg","./Digimons/AncientGarurumon.jpg","./Digimons/AncientGreymon.jpg","./Digimons/AncientKazemon.jpg","./Digimons/AncientMegatheriummon.jpg","./Digimons/AncientMermaidmon.jpg","./Digimons/AncientSphinxmon.jpg","./Digimons/AncientTroiamon.jpg","./Digimons/AncientVolcanomon.jpg","./Digimons/AncientWisemon.jpg","./Digimons/Andromon.jpg","./Digimons/Angemon.jpg","./Digimons/Angewomon X.jpg","./Digimons/Angewomon.jpg"]const img = randomimg[Math.floor(Math.random() * randomimg.length - 1 + 1)]message.channel.send({ file: img })message.channel.send("El digimon es: " + img.replace(/\.[^.$]+$/, ''));}module.exports.config = {name: "digimon",usage: "-digimon",aliases: ["di", "digidesc"]}In this case it shows me the image and the file name but I want to somehow remove the path.

As you can see above I've set ondblclick to myfunction.2 put a link to my script in the head.I want to trigger my function on double clicking the image, that function will then call an app.post() method in my server file.So in summary I want the double click to trigger my client side js file function which will then trigger a method on my server side js file in order to send the post request. Can someone please tell me what I'm doing wrong :P. Thanks.

For past month, i've been trying to improve my code and overall architecture of my applications. But i can not find any good repository, which shows how tests are done well.
So, I have been learning nodejs here and there for past year, progressed really far in my opinion, and i am also starting a job in a week as a node developer, but about month ago, i found out that almost everything i did, was kind of wrong. my whole code structure and "practices" were based of some of udemy courses out there, until i found out Bulletproof nodejs repo and article accosiated with it. i immediately started to migrate my personal projects to this kind of setup and honestly, i really liked it. I liked typescript, i liked separation of everything, etc, etc. but one thing i always did wrong was my testing i guess. or, should i say, i almost never did testing. but as i am going to start work, and i will be in a completely different environment, i want to learn how to write good tests, which are following same bulletproof structure and actually test for "everything". my main work will be to write mostly webpage apis and if you guys will be able to link me to some well-tested api repos, i will be happy. thanks in advance

Lightweight fullstack with TypeScript
First, I can be considered as a novice Node developer, as my experience with has been sporadic in the past.I'm working on an app, where I'm implementing the backend in TypeScript. This is actually an Electron app (shouldn't make any difference), with an additional admin interface that can be accessed remotely.As a lot of datatypes are shared with the backend (REST), I figured it would be a good idea to use TypeScript for the admin page as well.This would be a light weight page, using Bootstrap. What I haven't figured out 100% yet, is how to put this together. I got a separate tsconfig for the adminpage. Dependencies such as Bootstrap, jQuery (required by Bootstrap) are added with NPM.Then what ? Do I need a bundler, like Webpack ?

Can no longer access local website via iOS home screen icon after a few hours of server uptime
I'm dealing with some strange behaviour and I was hoping someone could lead me into the right direction.In Safari, I went to my local web app which is just 192.168.1.30:4500 and added the website to my home screen.Like the title says, when the local express server has been running for quite some time; I am no longer able to access the website through the icon on my home screen, it just says "Safari cannot connect to... or something". BUT I am able to connect to the web app completely fine via Safari directly at all times, just as long as the server is up.I can't really show any code but I was hoping if someone can tell me what's going on. Also I think it's important to note that I do not want any caching to occur since it's a live web application which constantly get's updated with the server.P.s. the web app is a create-react-app.I'm sorry if this doesn't belong here, please remove the post if so. I just thought this might have something to do with node or express.

Express/MongoDB Encryption Question
So I am building a Google Drive clone just as my first learner project, and the core functionality is working, but i would like to encrypt the files i store in mongoDB (using gridfs for large file sizes). I have been hearing about using the crypto module to do this (I want to continue to use read/write streams), which of course requires a cipher from a key. So i'm not sure exactly what to use as a key, and more importantly where to store it, I was thinking of using the hashed password stored in the mongoDB user model, but what would stop someone from just opening mongoDB (with something like compass on the machine), getting that hashed password, and then using it to decrypt the grid.fs data? Then I was thinking of just using some master key to encrypt all of the file data, but that key would need to be stored somewhere on the local machine obviously, so i'd just run into the same issue if someone got there hands on the server and went through the files.I've heard something about mongoDB having an option to encrypt all the data, but is this only for enterprise users? Wouldn't i still need to store the key somewhere, and how bad would the performance decrease be from encrypting everything?Idealing I would like to encrypt just the chunks that grid.fs creates, and avoid encrypting the whole mongoDB database (or even my disk).Small side note, wouldn't full disk encryption not be the beneficial? It's only beneficial if the machine gets turned off, but if the machine remains on, couldn't they get all the data just like a non-encrypted disk?Sorry I know this is a lot of questions, just kinda lost right now.

Unsure how to approach my Node API's architecture for a single page application
Hey everyone.I've written some very basic CRUD SPAs in the past, but it's been a while since I've gotten back in the Node.js land. I committed myself to making something "full-stack" using React, Node, and MySQL for the database. It will still definitely be a CRUD application, but I also want to dive into using some cloud services like Azure for content moderation (just for experience working with another service), as well as implement OAuth OpenID Connect for user authentication. This is stuff I've never tried in my prior CRUD apps.I want to approach this project more seriously than I used to when I was an extreme newbie, so this time around, I'd really like to design my application a bit better.This had led me down some rabbit holes, and I'm not sure if I'm spinning wheels or truly going somewhere. As a specialized front-end dev (and truly only having worked with SPAs), I'm not sure what a good approach is for architecting my Node API.I've found some articles on some patterns, such as the clean architecture, but I'm really not sure if this is something I should be worrying about?I think I am looking for a sense of direction. I have admittedly never thought about API architecture, and I feel like I am really struggling. Any advice or guidance towards the proper resources would be greatly appreciated.TL;DR: As a front-end developer, I know JavaScript, but now want to design an API in Node for my personal project (CRUD app). I want to use a nice architecture for the Node project, but don't know if it's worth spinning my wheels researching best practices.

[Beginner] How to create a Blog App where only selected persons can post?
I am a beginner who is doing Colt Steele's Course(not finished yet). I have made a basic Blog site where anyone can make an account and start posting articles.For a project, I want to create a blog site where only selected persons can post articles. I was recommended by some to check out "Admin panels", which looked a bit complicated (which I will look further into ofc, if its the best option).Another basic solution that I was suggested was to not create a registration page altogether, so people can not register. Only the selected persons who should be able to post, their accounts would be created via manual MongoDB entry creation. There would be a login page where only those selected persons would be able to log in.the second option makes sense, the only downside being that it will look very strange to have a Login button, but no Register /Sign Up button. Still, I like this because of the simplicity.Any suggestions? Thanks.

Proxy question
I am working on a backend express application and connecting the front end (react to this express backend)- I would like to have a proxy on the front end so that I can just make requests to the backend end points like thisfetch('/api/users').then(response => response.json()however, the proxy is set to set up correctly and poiting to port 5000 like this"proxy":"https://localhost:5000" # client package.json fileMy question is when I am now making requests on my front end to endpoints "/api/users" (which are stored in the backend ) I get a status of 500 Internal Server error. But when I change this request end point from "/api/users/ tofetch('https://localhost:5000/api/users').then(response => response.json()I am able to get the users from the backend.

Can anybody help on how to perform an action on queried MySQL IDs?
Thanks for reading. I currently have an Express server connected to a MySQL database and I would like to perform queried and for each row it finds, I would like to modify one or more of the variables. Below I will post two of my current snippets, one which finds all, and one which finds by id. Could somebody modify these codes to show how to change a variable or two in each (name them whatever).// FETCH all schools exports.findAll = (req, res) => { models.schools.findAll().then(school => { // Send all schools to Client res.send(school); }).catch(err => { res.status(500).send("Error -> " + err); }) }; // Find a school by id exports.findById = (req, res) => { models.schools.findById(req.params.id).then(school => { res.send(school); }).catch(err => { res.status(500).send("Error -> " + err); }) }; Also, sorry but I just thought of another question. Is there a way to do an array to the MySQL table so say at a set interval I grab a reading and put it into a table and pop off the oldest number? Say I want to store the last 10 numbers added to continuously without storing more than those 10?Thanks for your help in advance. I know these are probably easy questions for some of you but they've been really bogging my progress down and I'm not finding what I'm looking for online.

How would you go about this: 1) User interacts with front-end. 2) Back-end performs some tasks accordingly. 3) Notify user when response is ready.
I'm working on a web application where users can perform a "search" by filling out and submitting a form. The back-end will then use Puppeteer to pull some data from another website*. During testing, I've found that this fetching of data typically takes between 5 and 10 seconds.Now, when the data is ready I would like to notify the client somehow. I've been considering Socket.io but I'm still not 100% sure that's the best tool for the job.As things are, submitting a search will:Redirect the user to a page called "My searches" that basically gives them their search history (searches and results) and allows them to interact with it.Store the search in a database (MongoDB).Run Puppeteer to fetch "search results".Store the search results in a database, with a column "searchId" referencing the search.Now, I'd like to expand this so that after step 4, the user is notified. I have a few relevant scenarios in mind here:The user is still logged in and on the "My searches" page.The user is still logged in but navigated away from "My searches".The user has logged out.Regardless of the above - the user is also logged in on another device.I'd like to handle all of these scenarios. For scenario #1 it'd be nice if I was also able to update the UI directly (but in some way that makes it obvious that it happened).For the other scenarios, I'm thinking maybe I should implement navbar notifications? For that I guess I should probably store notifications in a database as well.Nonetheless - I still don't have any better ideas than Socket.io. And even then, I've never worked with Socket.io so I'm not 100% sure how to securely and relibably tie socket IDs to individual users. (Multiple socket IDs in the case of simultaneous sessions on multiple devices.)Is Socket.io the way to go here? Any other ideas?*I'm using Puppeteer rather than web requests because the website requires a login and some kind of MFA that I've been able to automate only with Puppeteer so far.

How do you avoid blocking the event loop?
Let's say you have to sort a large array of users. How do you insure that it won't block the event loop used to respond to HTTP requests?function sortUsersByAge(users) { users.sort(function(a, b) { return a.age < b.age ? -1 : 1 }) } Do you have to send requests for sorting the arrays to a new Node.js server and then asynchronously wait for the result? Or is there a better way? What are some solutions including the less optimal ones?

Preserve setTimeout between process exits
I want to have a notification dispatched to some users at some point in the future, when a poll posted by them on my platform has ended. There can be multiple of those polls and multiple users can be indulged in them. So when the poll is created, I can use setTimeout to notify users at the expiry date of the poll that I obtain from the users. But the issue is that the node process often restarts because of frequent changes I do to the code, and I have to re build it.. Once the process is quit, setTimeout is also lost. So how do I preserve setTimeouts between process exits? In this case using setTimeout is obviously not the solution, but then what could be the way out of this problem? I could store this notification in some db and have a cron job run every so often, but is there any other, more elegant solution?

Interview Question: What are some common causes of memory leaks in Node? How might you detect and address them?
Hey all,New-ish dev here. I recently went on an interview where I was asked "What are some common causes of memory leaks in Node? How might you address them?" I thought this was a really good interview question and I hadn't been asked it before.I'd appreciate any feedback on my response.Forgetting to unregister event listeners.Objects, global or otherwise, that are being referenced multiple times and aren't being garbage collectedClosures could be maintaining references to large objects.[this is all I could think of on the spot]"I haven't yet dealt with a memory leak problem but I would try to get some preliminary data. Ideally, we would be using PM2 or some other process monitoring tool in production for monitoring/logging and gather some metrics and insights. Is memory growing sharply or gradually over time? Is there one particular process or is it spread across multiple? If this is an API server, is there a particular offending endpoint?To further isolate the issue we can use node inspector and do some snapshot comparisons. Trigger a garbage collection to start from a clean state, then initiate a snapshot. Once we are finished profiling, we can do a comparison of the heap before and after. We can then use the inspector to drill into which objects seem to maintaining the largest size. If there is a clear offender, we can go back to the code and see if we can remediate the memory leak. We repeat the same process to test if we were successful."Anything else I might be missing or that I could improve upon?

Hello Internet,So recently I started looking for a new job as a full stack developer with Node.js on backend. I went to 7 interviews so far and every company was using Node.js just as a middleware for they microservice architecture (the other services were built using mostly Java and PHP).Honestly, I was expecting them to use Node.js to build bigger apps, like those apps from their microservice architecture.Why isn't Node.js used at this scale and why it's used as a glue technology?Of course, there may be companies that use Node.js for big apps but 7 out of 7 companies i was interviwed for used Node.js jusy as a glue piece.Is it because the frameworks available don't provide enterprise level features out of the box?

Express-Mongoose-MongoDB Question
Hello everyone, I am building some back-end services for a photography portfolio React app I am working on and would like to optimize my DB a bit more. Right now I have several documents, each with a container array, in a single collection that store image objects. Unfortunately, I am a bit new to Express/Mongoose so I was wondering what the code would look like for me to save a document into a completely separate collection, in the same DB, based off the genre of the image object that is send from the React client. Furthermore, I am also curious what the code would be to access a specific collection and then find an image object by id. Please note, that the ultimate goal here is to segregate image objects based off their genre so, for example, there would be an aerial collection that simply stores image documents. This method of storage would greatly simplify my current solution AND remove the need for me to store images within a container document's array.For reference, I am building all of my routes and async helper functions in a routing module that gets imported as middleware in the main app.js file. For reference, here is the Github for my source code: https://github.com/bryantb2/photographyReactApp/tree/master/serverSeriously, thanks a ton to anybody that can help with this!

Mongoose: Model1.Find, then for each result set attribute to Model2.Find, THEN render. How?
I'm trying to wrap my head around this but having some troubles.Basically, I'm first fetching "Search" objects, and then need to fetch "SearchResult" objects using SearchResult.find({searchId: search._id}, function(err, results) { ... });. I'm trying to set it up with callbacks, which for now looks something like this:function retrieveSearches() { searches = []; Search.find({}).sort('-_id').exec(function(err, searches) { if (err) { console.log(err); } callback(searches); }); } function retrieveSearchResults(searches) { search.results = []; searches.forEach(function(search) { SearchResult.find({searchId: search._id}, function(err, results) { if (err) { console.log(err); } else { search.results = results; } }); }) callback(searches); } retrieveSearches(function(searches) { retrieveSearchResults(searches, function(searchesWithResults) { res.render('profile', { title: 'Mine søk', searches: searchesWithResults }); }); }); Of course, retrieveSearchResults won't work because the callback is called before the forEach loop is done. I just don't see how I can loop through an array of objects and perform a single query on each and every one of them, use the result for something and then render.Any ideas?

A Simple Express JWT API Boilerplate
Whilst working on other projects, I usually found myself having to write user login/signup logic so I created a boilerplate to speed things up. I made this one with simplicity in mind as a lot of API Boilerplates for user management seemed too complex for my use cases.The boilerplate is well documented on the Github Repo for anyone interested in using it. Authentication is done with JWT through headers (See postman example in docs).Any feedback is welcome :)Express JWT API Boilerplate

TypeORM - Relation with property path ** in entity was not found
(see https://www.reddit.com/r/learnjavascript/comments/dy287f/typeorm_relation_with_property_path_projectrole/ for more in-depth explanation )I am struggling with joining from my projectsParticipants model. The thing that is unique about this model is that it uses field resolvers instead of @ManyToOne relations in the resolver itself.```@Field(() => projectsRoles)async projectRole(@Root() projectRole: projectsRoles) {return await projectsRoles.findOne({project_role_id: projectRole.project_role_id});}```When trying to join contacts or projectsRoles into projectsParticipants, I get an error when trying to select columns from the models I've joined. My "contact" column is also having problems. The thing that is unique about my contact column is that it has a composite primary key, so the field looks like this:```@Field(() => contacts, { nullable: true })async contactPerson(@Root() contact: contacts) {return await contacts.findOne({contact_id: this.contact_person_id,company_id: contact.company_id});}```

What is the best/simplest method for sending notifications to your phone?
I would like to set up automatic notifcations or SMS to my phone whenever my server runs into an error, or any other notification-worthy uses. My NodeJS application is running on my home computer and not running on my phone.Nexmo and Twilio look like the top commercial ways.

WeTransfer-like API for sending big files as email
Hello guys, I am building an app which needs to send a file as email attachment.The problem is, this file can't be send directly with nodemailer because it can be quite large (>100mb). I tried using WeTransfer API but it keeps crashing my app by using almost 2GB of RAM whenever the WeTransfer API is called. (My app only used 100mb of RAM when processing the file)Any suggestions or alternatives?Thanks in advance :)

How to split database models with SoC (separation of concerns) in mind?
Usually, a model should address a specific range of functions. For instance, the userModel addresses only things specific to a user. Nevertheless, when translated into code, does that mean that in the userModel, only queries to the users table is allowed?Allow me to illustrate this by an exemple. We have 3 tables like so:``` -- users id, email, password-- groups id, name-- users_groups_ownership user_id, group_id ```A user can belong to one or more groups, so for each group a user belongs to, there is an entry in the users_groups_ownership table.Whenever we want to get all the groups that a user belongs to, that's a job for userModel because we'll use a join from userModel.Now, if we need to add the user to a group, it would be an insert on the users_groups_ownership table, so should this be a dedicated model? Or inserting this table should be considered part of the userModel?I often find myself stuck in this kind of situation, not being sure if the structure is good or not. And I couldn't find any clear ressource on the matter.

React and electron
I have recently started creating apps with nodejs and electron. I've had my eye on react as it would dramatically reduce my workload.Only one problem: I can't find any good, working and up to date tutorials anywhere.I am aware that there is an official boilerplate but it looks unnecessarily complex for my use case and I would also like to become familiar with how the whole system works and this provides an opportunity.
