Is there a npm package to control another script?
Hi. I have a python scripts that asks for multiple parameters in execution time (depending on variable facts, so they cannot be passed as simple command line arguments). I have found a Python3 module that handles this, however my application is entirely made using Node and the only part using Python is the script in that file (because there is a library that I need which is exclusive to Python).In case you're aware of a package to achieve this, let me know. Thanks.

Critique my work. In house database migration handler for node-postgres ('pg').
I love NodeJS but don't like using an ORM. I like working with raw sql and the 'pg' module works just fine for me. The one thing stopping me from ditching an ORM was database migrations. I tried out TypeORM and noticed it tracked migrations using a migrations table and stored the name of the last migration that was run. Generating files with a timestamp and creating a migrations table didn't seem like a lot of work so I did it myself. Now I get the benefit of using migrations and not having to learn how to use an ORM.https://github.com/seanpmaxwell/InHouseDbMigrationHandlerP.S. the reason I didn't like using an ORM was cause I didn't like having to double check the SQL in my migrations and having to google how to do queries with the ORM when I already know SQL. I was like, what's the point of an ORM if I have to double check my sql anyways?

User Login / Registration System without database?
I came up with the idea to make a User Login / Registration System with node.js by simply storing the users' information in a JavaScript file. When a user registers, node.js would edit that file to add their information with arrays - for example, it creates an array named with the person's username and that array holds the username (again), the password and the e-mail. And when a user logins, node.js would scan through that file for matches. As far as I know, JavaScript files can be hidden from the user but I still want some advice, is it safe? Are there more clever ways to do this (excluding databases)?

Let's say I have 1 million promises in my node program that will never return, how does nodejs tell the kernel to handle these asynchronous functions?
I understand that the main event loop is a single thread and that the functions can execute asynchronously. I also heard that the async functions aren't multithreaded but instead scheduled by the Kernel..somehow that i can't really grasp.So I was thinking, if I have a promise that just does an infinite loop before returning a promise (so it never returns the promise and keeps on running), and I have 1 millions of those, how does the kernel and nodejs handle those functions? Will it still execute asyncronously? Will the functions, which are each processes have to share each core?

Very Peculiar Mongo Behaviour !
I'm using Passport, Passport-local-mongoose for User Registration and Management.When i create a token hash. It just get saved with "user.resetPasswordToken". This particular field is not existing in the User Schema Model until now when I have saved it.The peculiar part is if I change the name to anything else for example "emailverificationToken" then the token does not get saved in the database nor is the field created.Infact other than "resetPasswordToken" field I cannot add any other field to the user doc.Not really getting why.P.S. "resetPasswordToken" as already something I use for forget password system. Hence want to change the name to "emailverificationToken". But it's just not happeningBelow is part of my code for User Email Verification: -User.register(newUser, req.body.password, function (err, user) {if (err) {console.log(err);req.flash("error", err.message);return res.redirect("/register");}passport.authenticate("local")(req, res, async function () {try {var user = await User.findOne({ _id: req.user._id });console.log(user);var userEmail = user.email;var host = req.headers.host;var token = await crypto.randomBytes(20).toString('hex');user.resetPasswordToken = token;user.emailverificationToken = token;await user.save();await sendEmailVerificationMail(userEmail, user.username, host, token);req.flash("success", \An e-mail has been sent to verify ${userEmail}.`);res.redirect("/");} catch (err) {console.log(err);req.flash("error", err.message);return res.redirect("/");}});});});`Result{emailVerified: false,_id: "78839da18de156252410edf6b8",username: "abc",firstName: "abc",lastName: "abc",email: "abc@gmail.com",mobile: "2625351153",accountCreated: "2019-08-31T06:51:10.848Z",__v: 0,resetPasswordToken: "ads5fsdfg5df4gsd5fhsdfhsdhsdd"}Issue :- No filed created for "user.emailverificationToken = token;"Thanks in advance!

Is it possible to create a rest api using jwt token for a website that needs to track if the is logged in/out?
Hi, I have a website in node.js using express, all the current pages are ejs template files, that are rendered accordingly to parameters.If the user is logged in, he can see's more options in the navbar, an can access some options, like editing or deleting posts, which are not possible if the user is not logged.Using the session approuch with express I can know if the user is logged in or not while rendering the page. I set some information in the cookies using express-session, and I can verify this information to render the content in the page or not.Recently I learned how to create a rest api using jwt token, and I was wondering if I could change my current website to an rest api, which would serve the webposts information through requests, and also perform update/deletes if the jwt token is valid and autenticated.My problem is that I don't know how I would render the pages. For example, if the user is logged I need to render the page differently, with additional buttons and actions.Using jwt token I can know if the user is authenticated in the rest-api server, but my front-end server (the one that sends the webpages) wouldn't know this information and would be unable to render it correctly.How can I have the information if the user is logged, to render my views?

Or do you guys recommend me to re-create the complete project using jsonwebtokens for auth only and then trying to import the current users DB?Thanks!

How do i deal with dates and times from my mobile client?
How do I deal with dates and time inputs from my iOS/Android application?Lets say a user starts a event at 2.30, my app sends the information about the event and the time it was started.Now umm? What then? Because if I save that to the DB like that, the event wont be visible to sime others in different time zones, even if it should be! Should i also send a code of which time zone it is with the share?But then again, we are relying on client input for this kind of thing, WHICH IS TERRIFYING, AND SO WRONG. So obviously the solution would be to stamp the event time on the server while saving it to the db! But the problem is still the same lol, then its the servers time, and people in different time zones will see the event timing wrong.What would be the best way to deal with this?I know this is question really simple, and ill probably figure it out on google in the next hour.So why did I make this post then?Because theres something else...What about when i have to delay the time of the request to the server? If im sending large amounts of small data, thats usually what you have to do, postpone a upload to the servers to a more convenient time.BUT, the times on the stamps still need to be EXACTLY when the data was gathered.My application and this specific feature requires 30 second percision.What do I do then?And what if the user changes the time on their phone to a fake time, how do I verify that its correct?

Help with Mongoose Schema with existing Collection
A friend of mine wants a simple site to view some statistics that he has gathered. He has saved the data using mongodb and now I'm trying to create a simple api so that I can create a front end with the information (This is a sample of what each document looks like https://pastebin.com/KmxGSkPy)Here is my issue, I tried creating a mongoose Schema which currently looks like this:const mongoose = require('mongoose');const profileSchema = mongoose.Schema({_id: mongoose.Schema.Types.ObjectId,uuid: String,name: String,essentials: { nick: String },options: {showScoreboard: Boolean, allowSpectators: Boolean, receiveDuelRequests: Boolean}});module.exports = mongoose.model('Profile', profileSchema);If you looked at the sample data I provided you can see that this is missing kitStatistics and loadouts, but this still works and gives back all of the information from my api running this code:app.get('/api', (req, res) => {Profile.find({name: "Irantwomiles"}, function(err, profile) {if(err) {res.send("error");}res.json(profile);})})Note, that the current name of the file is profile.js. Now if I were to rename this file to anything else, the api just returns and empty array [] . So my question is why does this work when its named profile, but then it doens't work when its named anything else? Does a schema need to match exactly to what I have in my collection?

Sequelize always needs a primary key on join where there is no primary key '_indcies.id' is not found'
Hi all,Been in a full goolge circle for me. Maybe this is a limitation in sequelize but I'm asking hoping my assumption is wrong.When I learned databases in college it was my understanding you can use an index table where a pair of keys can become the primary key. So this is great when you need a 3 way association (this example uses 2 but assume 3)The modelsconst Access = sequelize.define('access', {id: {type: Sequelize.INTEGER.UNSIGNED,autoIncrement: true,primaryKey: true},label: {type: Sequelize.STRING},weight: {type: Sequelize.INTEGER}});const UserAccessIndex = sequelize.define('user_access_index', {access_id: {type: Sequelize.INTEGER.UNSIGNED,index: true},user_id: {type: Sequelize.INTEGER.UNSIGNED,index: true}});const User = sequelize.define('user', {id: {type: Sequelize.INTEGER.UNSIGNED,autoIncrement: true,primaryKey: true},account_status_id: {type: Sequelize.INTEGER.UNSIGNED,index: true},access_id: {type: Sequelize.INTEGER.UNSIGNED,index: true},date_created: {type: Sequelize.DATE,defaultValue: Sequelize.literal('NOW()'),allowNull: false},date_modified: {type: Sequelize.DATE,defaultValue: Sequelize.literal('NOW()'),allowNull: false},date_subscription_expiration: {type: Sequelize.DATE,defaultValue: null,allowNull: true},date_last_login: {type: Sequelize.DATE,defaultValue: Sequelize.NOW,allowNull: true}});Access.hasMany(UserAccessIndex, { foreignKey: 'access_id' });UserAccessIndex.belongsTo(Access);User.hasMany(UserAccessIndex, { foreignKey: 'user_id' });UserAccessIndex.belongsTo(User);When you join & use that modelawait User.findOne({attributes: ['id', 'account_status_id'],where: {id: userId,account_status_id: CONSTANTS.VALID_ACCOUNT_ID},include: [{attributes: ['access_id', 'user_id'],model: UserAccessIndex}]});I get something like 'user_access_indcies.id' is not found. Sequelize injects the need for the primary key. When I debug there is 'originalAttributes' (which are correct) but then the 'attributes' .Am I missing something here or is sequelize just this opinionated?

Pausing between API calls—sync or async?
Hey all, I'm currently working on a web app that involves lots of sequential calls to an external API. This particular API provides a list of data but it has a limit on the number of items that are given per request. For this reason, I have to loop through all the pages of the data to get everything I need. I wish to space out these requests by a second or so to minimize the traffic of the API.So far with node.js, all the external API calls that I've made have been asynchronous (using promises) because it didn't matter how long it takes to move onto the next step, but I don't think that would be the best approach for this situation. Based on this assumption, how can I accomplish this in a synchronous manner? If it makes a difference, these requests are being handled by a third-party NPM package that uses callback functions. I know that it's not a good idea to force pauses into what would be asynchronous code, but I'm not sure how to translate it to the functionality I need.Thank you so much for your input!

Help deploying a Node app built on IIS elsewhere
Hi, I would really appreciate some tips or guidance here. I’ve been asked to deploy a Node app to production that was built on IIS (I think they used an app service template on Azure). I seem to have got most of it working but I can’t work out how to re-write the web.config file from IIS to work as .htaccess.The web.config file is below. It looks like it has come from a template on Azure, as mentioned, and it needs the static content connecting to the public root and the dynamic content connecting to the Node app. Eg an image file should resolve as an actual file, whereas an endpoint created by the app should be routed to the app.I’m really not used to IIS and I’ve hit a bit of a mental block on how to do this! Thanks in advance.EDIT: sorry, I can’t get the code to post as a block, on mobile, am trying,,,Code moved to pastebin – https://pastebin.com/iGQtgfvp

If I put a ‘..’ in can you do anything with it, besides read data?My plan was to send a 403 if it contained a ‘..’ would this work? What other ways can the * be exploited?

Sharing code between projects. How do you handle this?
How do you guys manage shared code between your projects. There's various bits of code from our mobile app, website, API, and tooling that are more or less the same. It would be nice to have a symbolic link of sorts between these projects to share this code and keep things DRY. If it was just something on my computer, a symbolic link would be easy enough. But, of course, this is something that's managed with git and npm and such.Creating a dedicated repo and referencing it in package.json seems like the best solution I've found but if you're working on something that requires, e.g., augmenting that shared code, the dev cycle gets incredibly tedious as you now have to push to github, update your package.json, and then install it.Are there tools or features of npm/yarn or git that I'm overlooking that would make this more manageable?

Run a node app as a child process and start/stop from an API?
I have a node app (known as Alfred) that runs some services on our network at work. It's pretty hacky...and occasionally gets into a bad state and needs to be restarted. I'm not always around to do this, the company won't give me a laptop to remote in, and it causes problems if it's in this state for too long say, over a weekend). So here's my proposed solution:I want to run a simple Express server with an API that can start or stop my Alfred service. There would be a button on Alfred's front end that would hit this API, which would stop the main Alfred process, then start it again. Alfred would initially get started when I run this API server.Is this feasible, and if so, how might I accomplish it? The only I know for sure is that I would have to host this API on a different port than what Alfred is listening on...I think...and I feel like the child_process package might be involved?

DevOps/Deployment a little overwhelming for a beginner?
Hey all,I'm sure this question has been asked an answered hundreds of times, but I'd like to be a bit more specific for my use case.A little background, I am a Front End developer (circa 5 years, with 4 years of College), recently been building React projects. I have little to no backend or DevOps Experience (Other than seeing some jargon/services and briefly looking at a synopsis of what they are).I've recently been building a MERN stack application and have done a few tutorials on Udemy/FrontEndMasters to get to grips of backend development with Node (Which I am really enjoying and feel like I am learning a lot).However when it comes to the DevOps/Deploying side of things, I feel completely out of my depth with most of it, like, it seems so much more complicated/contrasting than just writing some code, also seems like there a lot of branching paths that can lead you down a rabbit hole.Any of the courses I have followed on Node development have detailed a reasonably basic deploy to Heroku without really delving into what I feel would be the real industry standards on deploying a Node.js application.Which leaves me in a scenario where I feel like there is a huge mountain of knowledge that I am missing out on and not sure where to look. Such as CI/CD, Docker, Kubernetes, Deploying to the likes of Digital Ocean/AWS/Azure etc.I get that DevOps isn't just one specific thing, but would like to know where to even start learning about DevOps in the Node.js world, any time I've tried to delve into research on this topic I get overwhelmed. Perhaps, it just isn't for me? 😂I guess my question comes in 2 parts.Are there any really good courses out there on more advanced deployment/DevOps so I can get my toes in the water? I prefer watching a video of someone talking through a topic rather then reading an article, but if there are some fantastic articles out there, would love to have a read through them too.What does your current DevOps/Deployment Strategy consist of with your Node.js projects? (Just so I can get a list of topics/services etc. to look into at a later date).Any help would be greatly appreciated!

Building a "use status indicator" app, want to make it real-time. Is sockets.io my best option?
Hey all. I'm making a ridiculously simple app to show the "in use" status of an account I share with a friend. Right now I have it built using express and a mongodb database that stores a single object that represents the current user of the account. The interface for updating this value is basically just three boxes on a page that contain text indicating the user, and some DOM event listeners that update the color of whichever box gets selected. This in turn updates the value in the database so that the "use state" is persistent. I have it so that on page load, the app queries the DB and the current user is indicated in the aforementioned manner. However, if the user value is updated, the browser must be refreshed to guarantee that the new user will be indicated accurately.I was looking into sockets.io to make the background color of the boxes update in real time - so if my friend were to log on and indicate that he's using the account, I'd be able to see the change in real time. This is my ultimate goal - to be able to see any change to the use status (as indicated by my app) in real time. Right now everything works as expected - page load accurately reflects the current use state of the account, and I can update the use state and view its status - I just have to refresh the browser to check for any changes to the status made by the other user.I know that the scope of this project is really simple and kinda silly, but I'm using it as an opportunity to play with some back-end stuff in a low-stakes way. I'm willing to share some code if anyone is curious or particulars are necessary for getting a better idea of what I'm talking about.Thanks in advance for your help!

How does socket.io scale?
Has anyone used socket.io extensively in a project? I'm looking to use it to stream audio data from the browser to a node server and then asynchronously run some processing on it, but I'm trying to determine what I can expect in terms of how many connections an instance can handle.If I ran the socket.io server on AWS EC2 autoscaling micro instances, how many concurrent connections would I expect to be able to handle per instance? Should i be more concerned with my memory usage instead of how many simultaneous connections I can support?Thanks in advance for any information! I'm just worried I'll deploy and the app will work for and that's it.

Remove white flashes in Electron when redirecting to another page.
I'm making an app using Electron and I have a simple page with my name, showing that I am the one who made the app. I used JavaScript to make it redirect to another page which is basically the application after 7 exact seconds. However, there is a tiny white flash before that other page appears. How do I make it disappear and give the page enough time to load so it can appear instantly, without flashes or waiting for elements to load when it's opened. Is that possible? I'm using windows.location.href as well as the 'ready-to-show' function in main.js.Thank you!

After installing / uninstalling some global packages, most of my tests in a specific project no longer run
I have a project with 1000+ tests that were working fine until yesterday when I installed / uninstalled some things globally and also locally in a completely different and unrelated project folder. Now, only 3 of the tests run.The test framework used in this local project is Mocha, which I don't use anywhere else on this computer except this project folder. I did change the ESLint package globally, and ESLint is used in the script to lint these tests. I tried removing the portion of the script that uses ESLint, but still only 3 tests run.Is there another way I can troubleshoot this, or maybe something I've missed? Thanks!*edit* is it possible I somehow have switched my default test runner for this project?

Why my Google Chrome is being opened through selenium webdriver in my puppeteer app?
Hi all , i am trying to do automation through puppeteer lib, i am trying to automate logging in into a website in chrome browser and doing some stuff there. So my problem is that i am putting google chrome's path in my code ( it is a right path ) but when i am running the code it works through selenium webdriver i guess. ( NOTE: I have other projects where i am doing scraping and that's why i am using selenium ). So do you know any way that i can use to make my code work though my actual browsers and not with selenium ? I have searched every forum in SO and everywhere but can't find even sufficient problem .Here is my code.const puppeteer = require('puppeteer-core'); //const email = document.querySelector('#email'); //const pass = document.querySelector('#pass'); async function login() { const browser = await puppeteer.launch({headless: false, executablePath: '/opt/google/chrome/google-chrome' }); // const context = await browser.createIncognitoBrowserContext(); const page = await browser.newPage(); // Focus input await page.goto('https://www.facebook.com'); await page.click('#email'); await page.keyboard.type('SOMELOGIN'); // Focus password await page.click('#pass'); await page.keyboard.type('SOMEPASS'); // Get login button and submit it const loginButton = await page.$('#loginbutton input'); await loginButton.click(); await loginButton.click(); await page.goto('https://www.facebook.com'); await page.click('#js_w > div._i-o._2j7c > div > div._7r84 > div.clearfix._ikh > div._4bl9 > div > div > div > div'); await page.keyboard.type('https://www.kickstarter.com/projects/boazinstruments/boaz-one-one-modular-guitar-50-combinations?ref=section-homepage-projectcollection-2-staff-picks-popular'); const postbutton = await page.$('#js_w > div._1j2v > div._2dck._1pek._4-u3 > div._45wg._69yt > button'); await postbutton.click(); // Wait if we get redirected to login await page.waitForNavigation() browser.close(); } login(); And yes, using puppeteer-core is mandatory , due to my project i can't use just puppeteer.

What is the best way to setup repository in GitHub for a college project so that all the members can show it in LinkedIn and their Github account?
Hi everyone! I am in my last year of CS course. We are required to do four projects to finish the course. In the previous semester, I created the repository for our project and did all the push and pull as my teammates were not that habituated with Github.I don't know much about how teams work with git and Github but I later added them as contributors and made them do simple push and pull requests. Now that we will add that project in our LinkedIn account, I noticed that the repository comes under my Github account only. They don't mind it as their names come up in the contributors but I kinda feel bad.So my question is, is there any better way to do projects in Github so that every one of my team can have the repository in their account. I was going through some options called Organization and team in Github but did not understand much.tl;drWhat is the best way for a team to work together on a project in GitHub and show it in their accounts?

How to handle admin controlled product list access?
I'm making a MERN app and have an "admin panel" of sorts with direct control over the products available in the DB. I'm wondering what would be the best way to actually implement this sort of thing alongside the public product list. Would an /admin route with authentication be the typical approach? Or would it be possible to have the admin panel output the actual HTML file that would be used for public, to prevent the need for users to query the DB at all?Sorry if this isn't the place for these kinds of questions, or if I'm asking this in the wrong way. I'm fairly new to this kind of thing, and am not sure what the next steps should be. I'm just not sure the right approach to keeping the admin stuff easily accessible but hidden/separate from the user experience.

Serving a Restify static site on nginx
I'm having some issues with this, wondering if anyone had any insights.I have a public controllerimport restify from ‘restify’; const { serveStatic } = restify.plugins; const directory = __dirname + ‘/../../../public’; const serveSite = () => serveStatic({ directory, default: ‘index.html’ }); const serveFile = file => serveStatic({ directory, file }); export default server => { server.get(‘/*’, serveSite()); server.get(‘/about’, serveFile(‘about.html’)); }; My static site (which is built using nextjs) is built and stored in /public on the server, remotely. My NGINX location directive looks like thislocation / { try_files $uri $uri/ =404; } Going to / and reloading serves the site correctly. Navigating to /about via the nav works fine, but if I refresh this route, I get a 404 page from NGINX. If I go to /about.html it works. Locally, just testing restify without NGINX involved, everything works fine so I feel it must be something to do with the server config.

JavaScript Singleton?
So I've been working on a small project recently. I'm fairly new to node.So, what I'm looking for is:client sends object to back endback end express server adds it to 'master' listat the end of the day, somebody can generate a report, wiping the days liststarts over the next dayI was thinking that I could use some kind of database, but I don't really like the idea of wiping the database every time somebody wants to make a report. Also , I thought that I might be able to do some simple csv file io, but I think that might be a little strange. Preferably, I'd like some sort of 'singleton' that will take any new objects and add them to the list. I'm not especially concerned about the performance issues this might have, but I'd love to hear ideas on that.Edit: Maybe I could just add them to the database (I want to use mongoose/mongodb) and when I want to generate a report, query the specific day? This might work, but I dont really like the idea of persisting essentially a bunch of useless data.

Simple package.json style IOC container for Node
I created an IOC container designed with simplicity and familiarity to package.json in mind. This was created to be the simplest possible way of mapping modules to their respective dependencies. Feedback on what people think of the dependency declaration-style as well as design decisions (such as auto-instantiation instead of the common factory-pattern), as well possible contenders that do the same (thus rendering it redundant) would be much appreciated. If anybody would like to comment on the technical implementation that would also be great (such as the subscriber-based dependency resolution). I think the performance could probably be increased by the use of certain log-n tree structures (instead of iterating as much as is currently done), or possibly priority queue for faster leaf-finding.

User Login System in Electron App (Using database)
I posted this in the electronjs subreddit but since there aren't many active users there and I found out people are posting here too about their Electron Apps, I decided why not? I'm absolutely sorry if there is already an answer somewhere for this, I couldn't fine one, so I decided to post a thread myself.It has been probably a month since I found Electron. I'm really familiar with stuff like HTML, CSS and JavaScript and always wanted to make desktop applications with those programming languages. It's basically a dream come true for me. I have made pretty simple apps so far and I want to go further. I was never good with server-side languages and databases. That 'never good' becomes even worse with Electron. I want to create a form where users can log into their accounts and explore the app like any other website. I am more familiar with mySQL but I still have no clue how to do this inside my Electron App. Is there any guide somewhere?Normally, on a regular website, the package.json file would include this:"start":"node ./server"But on Electron App, it has to be like this (from what I have learnt):"start": "electron ."So... how do I do this? Do I have to include "start": "node ./server" in my app or I'm fine with "start": "electron ."?I'd be extremely grateful for any kind of answer, as long as it expands my knowledge on this.Thank you!

How to stop someone scrapping my database using my api?
Hello, I come from a MVC .net background using Entity Framework where in my newbie opinion the backend feels much more hidden.I have a MEVN stack which is a public portal to search through a database of around 1000 contact records. The portal contacts my node API and returns paged results once 3 characters have been entered in the search-box. The site requires no authentication. If anyone where to investigate the network traffic in dev tools they can clearly see the how the API works. Appreciate its a public database, but I don't really want people scrapping my entire database.Is there any way I can prevent someone using my own API to scrap my entire database? Maybe Ip address throttling? Maybe encrypting the data being send to my API?

So I thought there would be a better way.

Boat - Borderless floating browser
Hi! I suppose this problem was already iterated upon in the past but I haven't had experience with an app that's minimalistic enough to suit my needs. Closest thing I've found was pennywise but it had its problems because pages were rendered in a webview (youtube.com/tv was not working at all for example).So I took the the matter in my own hands and just whipped up a simple electron wrapper that provides you with a way of having an optionally frameless browser window to play desired content while you work/study or whatever else you're doing.Boat has options to be frameless, always-on-top, preload urls and many more. Check out the repository here for more information.Contributions to make it work on Mac are desired as i don't have access to a Mac machine.PR's and feature requests are welcome!

Does anyone use a different file extension for your nodejs files to distinguish them from browser scripts?
Sometimes I write code to run in only NodeJs, and sometimes I write code to run in both NodeJs and browsers. If the former, I'm thinking about using an extension "nodejs". Does anyone do anything like this?

Is it a good idea to build a website ping/monitoring tool with Node.js?
I'm building a general-purpose website pinging tool, and need to make some kind of `setInterval` for pinging website with a given URL and check content on response.It seems obvious that I can just use `setInterval` to perform this, but it gets complicated if you consider having few hundred websites and each of them should be checked within a specific time interval. I had done a similar thing with Go by spinning separate coroutine for each individual timeout.With Node, I imagine that it is possible to do a similar thing using promises, but wanted to get some ideas if possible, is it a good idea to stick with Node for that kind of use-cases?Thanks!

Rename JavaScript again?
JavaScript has a few name changes behind it it started out as Mocha then LiveScript and last was to JavaScript it uses the word 'Java' because in that time Java was the most popular language. I think we are on a point where JavaScript needs a rebranding (New Name). JavaScript is now more popular than Java and do not neet this word anymore to be recognized, I would like the whole language to be renamed to 'Node' so nodejs and js come together under name Node as language. What do you think about this and will we see a rebranding again?

Promise in series.
With an API I need to make an "authentication" request to get a token then I need to make the "data" request that will return what I actually need, then I need to make a "logout" request. All completely obnoxious I know. I am trying to convert it all to asynchronous programming through the use of promises. Obviously those 3 requests need to be made in order. The solution I first came up with is nesting promises so login.then(token => { getData().then(data => {}) }) and so on. This feels really dirty like I shouldn't be doing it. Is there a better solution or am I on the right track?

For example a JWT module that automatically providers some endpoints for authentication. A framework where developers can create there own backend modules and share them with others. Just like React / Angular or Vue, but for the backend.Is there a framework that provides this for the backend, and if not are the developers that want to explore this idea with me?

Adding a self-destruct with a reset timer to a Node.js program
Over the last couple of years, we've experienced multiple partial outages due to various bugs in the Node.js ecosystem that resulted in our program hanging, e.g. database socket hanging without a timeout, Redis hanging, proxy agent hanging, etc. Usually this goes unnoticed for a long time (1-2 hours) because it only affects a subset of workers and there are no errors in the logs – the program is just hanging waiting for some event.Long story short, we ran into another partial outage today when we noticed that even though we have 1k+ active agents in Kubernetes, there were only 400 active jobs. Bug details are not important, but it made me think of what safety mechanism we could add to prevent this happening in the future. I am currently thinking of adding a sort of self-destruct mechanism that requires program to check-in every X minutes or otherwise it terminates the process, e.g.``` // @flowconst createTimeout = (interval: number) => { return setTimeout(() => { console.error('liveness monitor was not reset in time; terminating program');process.nextTick(() => { // eslint-disable-next-line no-process-exit process.exit(1); }); }, interval); };/** * This exists because of numerous bugs that were encountered * relating to hanging database connection sockets, http agent, * Redis and other services that resulted in Node.js process hanging. * This is a sledgehammer solution to ensure that we detect instances * when program is unresponsive and terminate program with a loud error. * In practise, this timeout is never expected to be reached * unless there is a bug somewhere in the code. * * Liveness monitor must be created once and reset trigger injected * into whenever program makes observable progress. */ const createLivenessMonitor = (interval: number = 15 * 60 * 1000) => { let lastTimeout = createTimeout(interval);return () => { clearTimeout(lastTimeout);lastTimeout = createTimeout(interval); }; };export default createLivenessMonitor;```Program would call the liveness monitor whenever it does something that indicates progress (e.g. a new task picked up from the queue). If program fails to check-in for X minutes, then the process is terminated with an error and possibly additional debug details.What are your thoughts about this solution?

Same JSON response for all requests in express, how would you do it?
So one of my requirements is that ALL responses must be of the following structure.{ success: true/false data: {}/[] } This even has to be done with any errors I send. No problem, expect...I have around 50 endpoints I need to make, so my res.json will be littered withres.json({success: true, data: someDatabaseResponse}); So I will end up adding this to every single route I have...mmhmm okay so I make a class instead.class ServerResponse { constructor(data, success = true) { this.data = data; this.success = success; } } module.exports = ServerResponse; This works expect...well same thing, every res.json will have a new ServerResponse class insteadres.json(new ServerResponse(dataResponse, true)); Maybe using middlewares? Well, then I will have to pass the success and true to the next method.next(dataResponse, true?) Either way I don't really want to be using next() anyways. So I ask you, is there a way in express to make sure all JSON responses have the same properties I want without defining it in every res.json method?

I've been learning nodejs and its server side stack(mongodb, express, etc.) and I already started a simple job as a junior dev, writing my first ever application when im hired, and i am getting close to deploy it. but lastly, i have been getting across a lot of posts on this subreddit about devops, and all i have been reading was stuff i really dont understand, like Kubernetes, pm2, Iaas, etc. and i have no idea if i need them, or should i learn them, so could anyone explain all of those stuff like you are explaining it to a child?

Would it be better to create multiple child processes for cpu intensive work or create separate node instances?
I have 3 tasks that are all time consuming. 1 is a web crawler, the second is analyzer that tries to match an image against other images, and the 3rd is a color analyzer of an image. Each is going to block for enough time that I don't want them all running on the same process.If I understand clustering correctly it won't really solve my problem because I want each task to have equal availability and if the crawler or the analyzer eats up all the room on the cluster than the color analyzer just waits.What I was thinking about doing was creating a child process for the 3 tasks so they can each run separately and just pass info back and forth. However, the same could be accomplished by just creating 3 different node instances and communicating via an api.In cases like this what would be seen as best practice or is there a 3rd option I'm not thinking of?

Should I use `nvm use lts/dubnium` or `nvm use 10` and why?
`nvm use lts/dubnium` and `nvm use 10` resolve to the same version and it seems to me like they always will? as I can't imagine why LTS would stop but a new version then is released after?So is there any reason for installing `lts/dubnium` via during each build instead of `nvm use 10` ?

Scaling In Nodejs for enterprise level apps
So I have been reading a lot about nodejs and it's ability to scale when used for enterprise grade applications considering its single-threaded nature but it is still not so clear to me... Actually am considering building a school management system using Nodejs backend you there is going to be alot of requests at a time to a particular api considering how much students and pupils can be.... Can nodejs effectively handle a system like this? Is it a right choice?

Question using multiple computers
Hello all -Full disclosure - my career to date has been in technology but never have I been a developer.I'm teaching myself Node.js for an upcoming position at work, but finding a tutorial on JUST node.js is pretty limited. I found a tutorial on the MERN stack and thought the skills would translate well since I have never done full stack dev.That I am using multiple computers to work through the tutorial and coding but I am having trouble keep the environments consistent. I am using git but until this tutorial have really only used it via copy paste and never had multiple directories... so I'm learning a couple things with this expedience.I'm certain I am not the only person who uses multiple computers. What is your process for keeping web servers and environments consistent across computers and projects?Not looking to have anyone solve my problem per-se as I'm very positive my issues are just related to my inexperience.Any help is appreciated!

Synchronous variable setting in nodejs
Sorry if this is too nooby for the sub. I'm messing around in nodejs and wanted to create variables that are set from db queries and then used later, once the connection is closed.However, as the db call takes nontrivial time, the variable initialization isn't happening until after the final line gets printed.Is there any way to ensure the calls are made synchronously, and the next line waits on the query to finish, without nesting each query?Note that the commented lines work as desired.Snippet:con.connect(function(err) { if (err) throw err; console.log("Connection successful!"); var totalRes; var distinctRes; con.query('select userid,name,address from MYTEST.people;', function (err, result) { if (err) throw err; console.log("Result: " + JSON.stringify(result)); }); con.query('select count(userid) as totalresults from MYTEST.people;', function(error,result) { if(err) throw err; //console.log("There are " + result[0]['totalresults'] + " results, with "); totalRes = result[0]['totalresults']; }); con.query('select count(distinct name, address) as distinctresults from MYTEST.people;', function(error,result) { if(err) throw err; //console.log(result[0]['distinctresults'] + " distinct entries."); distinctRes = result[0]['distinctresults']; }); con.end(); console.log("There are " + totalRes + " results with " + distinctRes + " distinct entries."); }); Output:Connection successful! There are undefined results with undefined unique entries. Result: [*entries*]

Phone call listener app -speech to text
-2I have to build a phone-call listener app - that performs operations such as you do - "Pay you bill over the phone". You give specific answers to specific questions, and you bill is paid. The exception is There will be another live person on the other end. You will not be talking to an automated system. This app will not be a credit card billing system, I am only using it as an example.I have looked into node.js api's for both google-speech-to-text and twilio. Still researching. AWS speech-to-text APIs are also welcome. But I have not looked into those.The phone number does not need to belong to a specific carrier. I can have any vendor. Domestic calls only.The system needs to work at least from the outgoing calls from my number. The user at the other end will be prompted to agree for recording.I need to be able to give cues to the system, as to what is being recorded: such as credit card number, expiration date, CVC.My preferred stack is Mongo-express-react-node.

Job Posts?
I've seen other subreddits that will post a weekly/monthly thread for people to post that they are either looking for work or looking to hire developers in the given language/technology. Does /r/node do that by chance? I've been subscribed to this subreddit for a while and hadn't seen one. Thanks.

Does await block code execution for every user trying to get a response from server?
Example: there are two users, asking for a response from the same endpoint at the same time. Lets assume one of them hit await statement a bit early(talking about miliseconds), will server wait for that statements execution before it continues code execution for second user? Or how does it work? Or does node do this without async await too? Im confused.. still kinda newbie..

Does installing a package from a repository install the release version?
If I install a node package that has a release version that includes optimizations like prebuilt binaries from a repository like this: npm install github_username/repo_name does that installation include all the goodies like a proper release when I use the command npm install package_name instead?

Inspect system information on a remote server from an express server
Hello,I'm currently building an express webserver to monitor activity on a list of server and I was wondering if a package exists to get cpu/memory usage on a remote server.I had a look at the `systeminformation` npm package which seems to do the job but only on the server on which Node is running.The other solution I have in mind is to try to find a package which could launch Powershell scripts/commands because this could provide a workaround.Any advice/suggestion ?Thanks,Bob

need a "captivating" nodejs course
Hi everyone,This is probably a noob question - apologies in advance if it annoys anyone...I'd really like to learn to code (something decent) - but most of the courses I've tried usually have me bored outta my skull a fifth of the way through -- the most fun I have (genuinely) is debugging when something I've coded doesn't work as expected.Short of heading to a physical school, can anyone recommend a genuinely captivating online coding course (does not need to be node - I'll consider other languages too) where you build something even mildly interesting besides a shopping cart.To give you an idea of where I'm at, I've recently enjoyed building a basic Discord bot using discord.js and some old youtube videos (that used deprecated commands) which was kinda interesting as I only started using Discord a month ago (and no, I'm not a gamer). I've done some basic Python courses in the past too - but nothing decent. I regard myself as a coding newbie, but very teachable.Cheers and please be gentle with your responses :-P -- If you do end up recommend something, I'd appreciate it if you substantiated your response.
