Preference for no front-end framework and doing everything from Node and Express, if front-end included, preference for React over Angular. I want the simplest scaffolded app possible. Can I do better (simpler) than mern.io/mean.js/mean.io? Expressjs generator is too minimalist - I want user model, sign-in, auth and cookies/sessions ready-made. Some add-on/fork to expressjs? Couldn't find it.A tutorial would be acceptable, too (or both). (I see this Okta + expressjs, can we do simpler? https://ift.tt/2L26FJw)

How can I edit data from table and push to database?
I was given a MS Access database with 10k entries per table(total 7 tables). I used ag-grid to display tables and export some entries. I've seperated table view part from data entry because ag-grid will only be used to check the entries and export it in CSV.Each table has 18-25 columns and I have used sequelize(psql) to create table schema and add entries. Now I'm wondering how can I edit those entries. If I display entries used tables(w/o ag-grid) using simple css then add edit button to it then page will be filled with several tables.I'm looking for an alternative way to edit those tables. Can someone provide me some good ideas on how to do it.In short: I want to update and delete the entries from a table and each table has 10k entries.

Reuse/extend my tornado authentication for my node application.
Hello all,So I am running a tornado application which has users and they can use PAM authentication to authenticate to my application. I am also providing them to start a node js app.But that node app does not have any authentication. So if other users can get the url of my other user they can access it. Is there a way I could extend the already authenticated tornado server to my node. The node app does allows plugins so I could modify it.Thanks for all your help and sorry for such a noob question. I am just learning node for the very first time.

ReactJS SocketIO bug or user error?
TLDR; When calling socket.emit inside of socket.on listener on the server, the emit is not received by react, but works in raw HTML.I created a boilerplate example of this issue to try and nail down what is going on here. I have a simple server.js app that is running express and SocketIO on port 4001. I then created both a raw index.html page, and a simple react app (using create-react-app) to demonstrate the difference. Both have a button that sends a "test" emit to the server, and they listen for a "Hello World" from the server. When they receive "Hello World" from the server, they pop up a simple alert saying "Hello World Received." Interestingly enough, I only have an issue with this if I use socket.emit('Hello World') in the server-side socket.on('test') listener (specifically trying to send to the originating client). If I use io.emit('Hello World'), it works fine on both the html and react app. I have included snippets of my react App.js, the server.js node app, and the raw index.html. I have also zipped up the files here https://ift.tt/2PbvtwA so that someone can possibly verify what I am seeing.To test, run npm install on both the main directory, and the socket-client subdirectory, run nodemon server.js from the main directory and run npm start from inside the socket-client subdirectory. As it is written, if you connect to localhost:3000 you will get the react app, and if you connect to localhost:4001 you will get the raw index.html.In server.js, you can switch between io.emit and socket.emit by commenting out one of the two lines. The results of each are shown//io.emit('Hello World') //HTML: YES REACT: YES socket.emit('Hello World'); //HTML: YES REACT: NO If you go to localhost:3000, click on "Send Test Socket" button, you will not get an alert, despite the server getting the emit and sending the "Hello World" reply back, it's as if the client doesn't get the emitIf you go to localhost:4001, click on "Send" button, you will get an alert, which is what you'd expect from the server.js codeIf you go to server.js and edit lines 20-21 to uncomment io.emit and comment out socket.emit, suddenly both the react and index.html buttons work as expectedExtra: if you go to server.js and put a socket.emit('Hello World') on line 16 (inside the io.on('connection') listener), you will get the alert on both react and html versions, it's specifically an issue inside the socket.on() listenersBoth "clients" are pointing to the same server.js, so what is going on here? Am I doing something wrong with how I am listening on the react side somehow?I hope this better documents the issue I am experiencing. Let me know if I can provide any further information.server.jsconst express = require('express') const http = require('http') const socketIO = require('socket.io') const port = 4001 const app = express() const server = http.createServer(app) const io = socketIO(server) app.get('/', function(req, res){ res.sendFile(__dirname + '/index.html'); }); io.on('connection', socket => { console.log('New client connected') // just like on the client side, we have a socket.on method that takes a callback function socket.on('test', () => { console.log('Test socket received') //io.emit('Hello World') //HTML: YES REACT: YES socket.emit('Hello World'); //HTML: YES REACT: NO }) socket.on('disconnect', () => { console.log('user disconnected') }) }) server.listen(port, () => console.log(`Listening on port ${port}`)) App.js (react)import React, { Component } from "react"; import socketIOClient from "socket.io-client"; class App extends Component { constructor() { super(); this.state = { endpoint: "http://localhost:4001", }; } send = () => { const socket = socketIOClient(); socket.emit('test') // change 'red' to this.state.color } render() { // testing for socket connections const socket = socketIOClient(); socket.on('Hello World', () => { alert('Hello World Received') }) return (
) } } export default App; index.html

npm trends show 0 downloads for a few days
I was looking at trends from npm on npmcharts.com and noticed that there were a few places where the downloads dropped to 0, namely May 30-31 and November 6-14. I looked at the status tweets from npm and they don't seem to show any major service failures, so I don't really understand where these trends are. The only thing I can think of is that the download rate api was down at that point and npm just didn't share any information about it. Anyone have any ideas?

advice for web / data lab engine
I have been messing about with node for a couple of months now. Our company monitors industrial equipment and works more like a data lab than a website (though we do host our own website). We use MySQL, ruby, and python for most of the data processes and Rails for the website. Our process is mostly made up of different scripts running all over the place. I want to clean it all up and make it more efficient.My questions are these:1) If I built a server, like with express or somesuch, would that API through HTTP requests be as fast as simple socket servers to receive a machine report and process the data then save it to the database? Is there much overhead between a simple TCP socket and an HTTP request as far as speed goes?2) Our website is huge and synchronous in the way it loops through a customers list of machines to produce tables, etc. I wish to replace it all, but is it feasible to replace parts of it at a time? Not sure how I would configure Rails to do so (it's 2.3.5, yeah, i know) or if I could do it a page at a time. Or, how clumsy would it have to be to embed some processes or website components from a node server into a view served up by Rails? I think I could pull this off if I can configure it correctly and if I can do so without it being a convoluted mess.I have been experimenting with Objection.js and so far, I really like it as an ORM'ish alternative. Sequelize looks good too, mostly because of the Rails throwback in syntax. Express looks good for web stuff and, maybe for some data processing server side. Anyone done anything similar? Like used express to process a lot of data or run process that are not web/api related?thanks for any tips

I've got a Socket.IO / NodeJS application I'm working on that has a module for handling various buttons (just to keep things clean and separate). If I make handleButtonScripts use io.emit, everything works fine, but I want to be able to notify just that one socket that pressed the button (hence client.emit) but I never get the HelloWorld emit on button presses. It's like the client var isn't passing through to the module the way I'm intending. Can anyone shed some light here for me?Thanks in advance!buttons.jsvar handleButtonScripts = require('../helpers/handleButtonScripts'); module.exports = function(io) { io.on('connection', function(client) { client.on('buttonClicked', (button) => { handleButtonScripts(io, client, button) }); }); }; handleButtonScripts.jsfunction handleButtonScripts(io, client, button) { client.emit('HelloWorld'); }

Express serving static files without actually making a call to 'res.sendFile(...)', help appreciated.
Hi, y'all, I've got a pretty standard express node / react app here but I'm getting some weird behavior.Like any typical setup, to serve static files I have,app.use(express.static(path.join(__dirname, "client/build")));...later in the file, we have,app.get("*", (req, res) => {console.log("hi");res.sendFile(path.join(__dirname + "/client/build/index.html"));});I would expect the request to reach that route, then serve the file. However, it looks like the file is served at the first line. I'm not sure what's happening, I haven't had this experience before when I've previously built react/express apps.I have a feeling it has something to do with the fact that when we pass the express.static( ) to the app.use( ), it's automatically serving the index.html...I'll go ahead and post full code below.const express = require("express");const app = express();const bodyParser = require("body-parser");const session = require("express-session");//pass session middleware to sesssion storeconst MongoDbSessionStore = require("connect-mongodb-session")(session);const userRoutes = require("./routes/user");const emailRoutes = require("./routes/email");const workoutRoutes = require("./routes/workout");const loginRoutes = require("./routes/login");const { mongoUri, sessionSecret } = require("./config/keys");const isAuth = require("./auth/isAuth");const path = require("path");// allow express to serve static content from react-build//init and configure storeconst store = new MongoDbSessionStore({uri: mongoUri,collection: "sessions"});const mongoose = require("mongoose");mongoose.connect(mongoUri,{ useNewUrlParser: true }).then(() => console.log("MongoDB connected")).catch(err => console.log(`There is an err:${err}`));//init session with store for the appapp.use(session({secret: sessionSecret,resave: false,saveUninitialized: false,store}));app.use(express.static(path.join(__dirname, "client/build")));app.use(bodyParser.json());app.use(bodyParser.urlencoded({ extended: false }));app.use("/user", userRoutes);app.use("/email", isAuth, emailRoutes);app.use("/login", loginRoutes);app.use("/workout", isAuth, workoutRoutes);// app.use(express.static(path.join(__dirname, "client/build")));// generic catch all routeapp.get("*", (req, res) => {console.log("Request never comes here lol wat??");res.sendFile(path.join(__dirname + "/client/build/index.html"));});//why are we hereapp.use((req, res) => {res.send("

Are there better ways of synchronously executing dynamic async functions/promises?
I was hitting an API that had strict rate limiting and therefore wanted to hit the API one request at a time, keeping track of how close I was to hitting the rate limit and pausing execution if necessary. I came up with this solution, but I'm not satisfied with its maintainability/readability/reusability and was wondering if there were other more standard ways of accomplishing the same thing. I've commented the code and removed the error-handling logic for readability. The gist of it is there's an array (queue) that stores async functions waiting to be called. When a client calls the call_api function a new async function is created which wraps the main api call and updates the rate-limiting info after receiving the response from api server. The async function is then added to the queue, where it waits to be executed. Execution happens in a loop that checks the rate-limiting variables first. There is example client code at the bottom. The effect is that the client code doesn't have to know about the rate-limiting - it just awaits the response.https://ift.tt/2PXXltD apologize for the length. I'm not looking for a code review necessarily, just seeing if I'm missing something really obvious about a better way to accomplish this using some idiomatic javascript concept that I'm unfamiliar with.

Can/should I outsource a login system with Node? Or should I do it myself?
I'm no security expert. I have basic knowledge of salting, hashing, two factor authentication, but I've never built a properly secure login system before.I'm building a website that will involve a user login system (no financial info involved), and I want to make sure it's done right. Are there cloud services or something similar that I can use to outsource this portion of my website? I love the idea of Facebook login, I use it a lot myself, but not everyone wants to do that or even still has Facebook for that matter. I may still offer that but I don't want to rely on it.Or perhaps I'm over thinking it. Is it as simple as using a secure hashing algorithm like BCRYPT on the password and be done with it? I'm not in the industry, just a hobbyist, so I don't know what the "standards" for security are. The only confidential information my database would store are password hashes.If anyone has any resources they would like to share, it would be much appreciated!

So the idea is the client makes a request to a task manager. This task manager makes jobs from this request and stores each job state along with id in DB and returns the job ids back to client. The task manager then pushes it queue. After the queue consumer is done processing it sends an ack back to task manager (who was the producer). This task manager then marks this job as complete. Meanwhile client was polling task manager for state of job, which now comes back as completed.I have looked into Kue, Agenda, Bull, bee-queue. But they dont have rest-api layer to communicate or persistence.Was thinking if there is any ready made solution out there for this job for node? Was thinking of using RabbitMQ but then would have to do state management myself.Please help.

Does this method of connecting to mongodb create any memory leak?
So this is how I am connecting my nodejs app to mongo db,const mongoose = require('mongoose');const options = {useNewUrlParser: true, useCreateIndex: true};mongoose.connect('mongodb://localhost:27017/logindb', options);And I just imported it in app.js and all models which seem to be the only two places that it is required. By having it like this, am I creating too many connections or something everytime I import it? Because I recently saw a medium article writing the connection object as singleton and exporting it. So this question popped up although the app is working fine.The snippet from the article below.let mongoose = require('mongoose');const server = '127.0.0.1:27017'; // REPLACE WITH YOUR DB SERVERconst database = 'fcc-Mail'; // REPLACE WITH YOUR DB NAMEclass Database {constructor() {this._connect()}_connect() {mongoose.connect('mongodb://' + server '/' + database}').then(() => {console.log('Database connection successful')}).catch(err => {console.error('Database connection error')})}}module.exports = new Database()

Should I use ES modules or CommonJS for my libraries and applications?
I'm a bit confused about the current (and future) state of ES modules in node...Is node considering ever dropping CommonJS in favor of ES modules?Is there a recommended and future-proof approach, or is this topic a holy war?I'm currently developing a small library, primarily for node, but I might want to port it to browsers at some point.Am I recommended to use ES modules or require?If I went for ES modules, I'd have to transpile my library using babel, right? I can't expect people to use --experimental-modules just for my lib... It wouldn't be a big deal, anyways, since I'm using @babel/plugin-transform-modules-commonjs already.What bugs me more than transpiling is require(...).default as it looks ugly and pointless - are there many packages out there doing it?And what should I use when I'm developing a program, rather than a lib?

First project not using Mongoose, would love a code evaluation
Hey everyone,I'm used to having my project split up into routes/controllers/models and using Mongoose to handle the last one of those. Decided to give the native Node.js MongoDB driver a shot. Code works, but I suspect my project structure isn't 100% best practices. I figured I would just have my routes in index.js and only modularize the controllers - is that OK for such a small project? And basically anything else you can find that is wrong with the project, please mention.https://ift.tt/2KCGjv7 everyone!

Question about npm package security and restricting access
If we run a package (not with elevated permission) from npm (I'm on Windows, if that matters) can it access the full filesystem? Or just within the the directory it was run from? If the former, is there a Node setting to restrict it? Does it matter whether the package is installed globally or as a project dependency?Also, more generally, if the package is malicious, assuming it is not run with elevated permission, are there are security risks with it, in terms of installing malicious software on the host, stealing data, etc. Or is it rather limited in what it can do?

Private dev site to share with team: Git and express-basic-auth?
I'm currently developing on a local machine and want to create a development or test site I can use to share with a couple other developers. I'm planning on using dev.mysite.com, but was wondering what the best practice is to prevent this from being indexed by Google or being seen or accessed by anyone.Would it make sense to install Git on the dev server, production server, and my local machine, push changes from local to the dev server for review, then to the production server when testing is complete?Is it okay to have the dev and prod sites on the same server but in different folders, instead of configuring a whole separate server for dev? Any advantages or disadvantages to this?Is it okay to use express-basic-auth with the challenge option to prompt for a username and password, and will that be enough to prevent indexing and access?Thanks

Newbie help! Authentication strategy for storing data permanently in a database? And for different types of users?
Greetings!First, I'm very much a junior dev, but this is a great opportunity for me to learn and build something fun.I'm working on an app which, in essence, allows consumers to log in and favorite things they like, and store those things to the database. In other words, authentication can't just be a temporary token thing that'll expire and reset their favorites. Once the user clicks to favorite the item, it needs to go to the database and stay there, and the database needs to recognize them every time they log in. The only other things I might need to store are basic, like an email address and a city/state.I also need to create a login for producers, where they can post and edit the entries (which the users can then favorite). Like the consumers, the producers' posts need to be stored in a database and persist forever (unless they choose to edit it).They need to be completely separate -- meaning, consumers shouldn't have the functionality of producers (they shouldn't be able to post/edit items), and producers shouldn't have the functionality of consumers (they shouldn't be able to favorite things).If you were in my shoes, what would you use to authenticate these producers/consumers? This is my first time ever really messing with authentication, so I'm more than a little lost. I don't see how something like a temporary token is going to help with long-term data storage, so what program/strategy would you use to create those separate logins? Something like Passport?(This might be a really stupid question, but authentication is mind-boggling.)If it matters, I'm using React/Redux/Express/Node/MySQL.Thanks in advance!

Help with P2P (new to node and network programming)
Hello. I am in need of help. I study CS and need to make a P2P Hangman game. For starters, I have never programmed a P2P application nor a network program in general. I chose node because I thought it would be ok to go with it as there are no restrictions to language. The only restriction is that I need to use sockets, no frameworks. I'm struggling to figure out how I am to create an only program which is a potential server and client at the same time (that's what I understand from P2P). The first thing is... How am I to check if an instance of the program is the first to be executed or if there's another one (so that the first may open a connection to a server on a specific port)? Also, any great advice on network programming, P2P and node is welcome.

Simultaneous Time Intensive HTTP Requests
I am running Node on a RPi as a backend. Every minute it needs to HTTP Request from 40 clients more or less simultanously. The payload is very small and needs only to be done every minute. The problem is that the response time is around 500ms per client + DB writes. I had problems in the past of them locking up the main thread which is why I now delay each request by some milliseconds and use tight timeouts. Is there anything more I can do besides writing everything as asynchronous as possible? Even though this is not a CPU intensive task, would this be a candidate for offloading work to another thread?Thanks in advance!

Subject hopefully provides the gist of what I am having trouble understanding as a noob.On a get to my web app, I want to make three http requests to JSON services and send the JSON to an EJS page.The part I am having trouble with is the async/promise part of retrieving the external data:app.get('/', function (req, res) {x = make http request 1y = make http request 2z = make http request 3res.render('index', { x:x, y:y, z:z, error:null });});I think I should be writing a function to make an http request to an external service and return a promise. Then maybe use Promise.all to wait until they have all completed and failed.I really would appreciate an example/shell of exactly how to do this.

It feels a little like taking a step back.Is there another pattern I could look at that may make more sense? Is there a good breakdown of which patterns fit which situations better?Note: I am self-teaching, have a very slight comp sci background from a few semesters in college, but have mostly been learning Vue for the last two years or so.

tl:dr; i'm dumping json objects into a log file, server-side. what's out there for legibly presenting me that information through a simple node module? i'm open to serving it out to the browser but am leaning towards something at the command line so i don't have that security hole to patch up.i've inherited a project developing an ionic app and (unfortunately) a python server. the python server is basically a proxy to a third-party SOAP API and after some whittling, it's only real responsibility is to capture logs for debugging.the logic for dropping the requests and responses into the log a legible way was slowly getting out of hand, and the 12-factor app principle of dumping everything into a pipe for possible eventual consumption has been making more and more sense.meanwhile, i've started using winston for logging in the app and love it. 12-factor seems to hinge on the developer being able to pick through the logs for what's relevant but i've opted for a couple reporters that scrape the events, assemple them as needed (like matching requests to their responses) and show me what i'm looking for. i can look at events that were fired, api calls, snapshots from form submissions, etc. -- or just look at them in one big list. but with the browser at my disposal (i pop a new window) those lists are basically tall rectangles with dressed up object dumps stacked left-to-right -- so side-scrolling over past a long entry doesn't take any longer than a short one.anyway, i'm probably getting off topic so back to the server logs: i've switched them to dump json objects to the log file as winston would and assumed there would be existing options out there for what i'm trying to accomplish ,which is kind of open ended but boils down to "let me quickly read the end of the log file to debug issues".for now i've written a small utility that handles it but doesn't watch the log file -- i have to run it and it shows the last 50 logs (or whatever i've changed that variable to). i can certainly build on it and enjoy having my first excuse to use chalk, but i get the feeling i'm reinventing the wheel.i did find one npm package that i can't seem to find today that looked very promising, is built on ncurses and uses hotkeys for navigation. i ran into an error with that one and may poke into it, but i'm on Windows and have no idea whether that means ncurses is available. all i know about ncurses is that it somehow, you know, makes the console look way different from a CLI. and all i know about Cmd.exe is that it's the worst. linux is in my past and future but unfortunately not the immediate present due to the circumstances.

Cannot test a simple route with Jest
I have been trying to test this route for 4 hours now, and I can't seem to make it work.So i have a route like this:api.post('/register', (req, res) => { let hasErrors = false if(!req.body.name || !req.body.email || !req.body.password){ hasErrors = true } if(hasErrors){ res.status(errCode.invalid_input).json({ message: 'Invalid input' }) }else{ const NewUser = new User({ _id : mongoose.Types.ObjectId(), name: req.body.name, email: req.body.email, password: req.body.password }); NewUser.save().then(saved_user => { res.status(201).json({ message: 'User registered', user: saved_user }); }).catch(err => { res.status(500).json({ message: err }); }) } }) ...which I'm testing using Jest and Supertest:it('/register should return 201 if valid input', (done) => { //mock valid user input const NewUser = { 'name': 'John Wick', 'email': 'john@wick.com', 'password': 'secret' } request(app) .post('/register') .type('form') .send(NewUser) .expect(201) .end((err) => { if (err) return done(err) done() }) }) And the test is pending, and It gives me Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.I have tested this /register endpoint manually with Postman, and indeed, when I call the /register endpoint with Form URL Encoded data (name, email, password), it works and adds a new entry in my database. If I send the data as Multipart Form, it doesn't work and gives a 422 Invalid Input. Maybe that's the cause of my problem?Cheers!

Help with transform stream newbie here
I have 1m ohlc data coming live from a ws data source. I am trying to convert it to 5m 15m 30m 1h etc and am confused about something. I read the docs and understood that I implement a _transform method that takes input and calls a callback. Should my _transform method convert incoming data into all timeframes and push each one or should I have multiple Transform instances where each one does one specific conversionApproach 1 One Transform stream that pushes alllet r= new Source()let t = new Transform({_transform(chunk, encoding, done){this.push(data['5m'])this.push(data['15m'])...}})Approach 2 Multiple Transform Streamslet r = new Source()let t5 = new Transform("5m")let t15 = new Transform("15m")r.pipe(t5)r.pipe(t15)I noticed that I cannot nest pipe calls because it goes from output to input but I want 1m as input to eachThe second approach seems like it loops through all 'data' event listeners and fires each oneWhat is the right way to do this and is there a better approach? Thank you in advance

request-promise, return value
I know this must be a common problem but I am yet to find the a working answer after many hours of digging so I am going to ask for help. Chaining the requests works as expected, however I am having trouble ending up with the result of the final web call being returned. I do understand that its the async nature of node, but I don't know how to get around it.const request = require('request-promise') const options = { method: 'GET', uri: 'https://ift.tt/1HYwxQm' } //should make multiple web requests and return the final value var x = request(options) // First call would be to get a JWT .then(function (response) { console.log('first:' + response); //need to modify some of the options for second call for data options.uri = 'https://ift.tt/2AflKjC'; }).then(function(){ return request.get(options); }).then(function(response) { //this is what I want returned console.log('second:' + response) }).catch(function(err) { console.error(err); }); console.log('Return value:' + x) The result:Return value:[object Promise] first:6 2 3 2 2 6 3 1 6 2 second:2 1 1 2 3 Everything works within the request, but since the final console.log runs before the requests have completed, it's just returning a promise and I need it to return the value of the final call.Any help appreciated.Thanks!

Currently I have a webcam that streams a webm buffer using socketio to a server, but I have no idea what the best practice from there is to then have a route ending in .webm that would just resolve the video stream. I will be piping this .webm url into cv2 of python so the url needs to literally resolve a video stream in .webm format. Thank you for any suggestions and help in advance.

New to web dev, I'm trying to 'insert' into couchdb an array of tag's. I think I'm probably just not seeing the right 'angle' to tackle this problem. I'm trying to do a function in the app.js post function that takes in the string from the box and replaces the 'tag' section with what I want, but I'm not sure how to return it properly given I can't return it as a full string (i.e. "tag1, tag2, tag3") it has to be strings seperated by commas ("tag1","tag2","tag3"). Can you just point me in the right direction? maybe I should be doing this in the webpage js instead, or is there a cleaner way? //working, passing just the value couch.insert('master_db', { //accepts the following properly //tags: ["tag1","tag2","tag3","tag4"] //just takes in the whole thing like a string value (1 tag) tags:[tags]; }) /*couch.insert('master_db', { tags:[(function(tags){ console.log("got here"); console.log(tags); var array = []; var string =""; for (var i = 0; i < tags.length; i++) { if (tags.charAt(i)==","){ array.push(string); string=""; } else{ string=string+tags.charAt(i); } } return array; })] })*/

Creating pdf documents with node
Hi,I have a letter saved as word document that i currently fill with certain fields for each user i have in my system. I do this manually and then save it as a pdf before sending it in an email.I am developing a MEAN stack app that can send emails etc and store all the users for my system, and now want to start generating these letters at the backend automatically. The options I have come across so far would be creating pdf or templates using npm Javascript libraries or html. This is fine if i have one doc but if i plan on having more in the future, creating this template for each doc is quite time consuming. Is there a way in node to open a word doc replace place holders and then save as a pdf or something similar, so that i could use word to create templates rather than hard coding templates. (or any other interesting solution for that matter)Thanks

Web app running into issues when multiple users upload files at the same time
I am quite new to node/javascript in general and I have an issue with my angular app that has the traditional client and server running on nginx. There's an authentication functionality that requires users to log in. Separate users can use the app to upload files, extract the data, store that information in a local sql database using sequelize, and then update the processed data in an AS400 database using odbc drivers.The problem comes up when the users hit the submit and confirm buttons on upload at the same time. As the processing of each request by the server can take up to a minute, different users uploading at the same time can cause the app to crash, suddenly returning partial results or undefined errors from null array values. I am not sure where the problem is because I tracked the progress of the data through the app's async/await functions and it stops in the back end, with arrays full of data objects suddenly being reset to empty.Could this because the app is not using object instances? Here is how I reference the document-upload.js file:const uploadHelper = require('./document-upload'); Here is how I call the methods in that file:await uploadHelper.processFile(file.path); const batches = await uploadHelper.getBatches(user, file); Would a possible fix to this be to create multiple object instances of the uploadHelper so that there's no interference between different users? Or is this an issue elsewhere?

Springboot Web App on NodeJS
Hi all,I'm confused. I've developed a Springboot web application which I have no problem to run on my own workstation. However, I am unable to deploy it to the hosting service I bought (it uses DirectAdmin Panel). As far as I know, I should be able to deploy it as .war in Tomcat but was unsuccessful to do so (as my hosting does not have Tomcat installed (I guess?)). I've also tried to use this method but it did not work too.I asked my admin why it was not working and he replied that he has now installed nodeJS and I should not have any problems deploying it now, I just need to configure it.What I don't understand is how NodeJS stand in all this situation and how the hell should I deploy my JAVA app in NodeJS?I do understand that I am missing something somewhere but I fail to understand WHAT exactly.

Choosing process manager
Hello I am looking for a process manager for laravel-echo-server (NodeJs server for Laravel Echo broadcasting with Socket.io). I need process manager to track crashes bugs, keep process alive. But it is the only process I will be monitoring and I don't think I need much functionality, crash and events logs and maybe emails for crashes. I need an free program for this. Currently taking into consideration pm2 (runtime version, is it free for non open source projects too?), forever and supervisord (process control system for unix). Which one would you recommend?

Is this the correct way of doing AWS Lambda with Nodejs ?
For a big open source Terraform Module which serves as a module to simply deploy dockerized services to AWS, I've written a helper AWS Lambda in Nodejs. I've chosen Node as it's lightweight and it's important that it's readable to as many as people possible.You can find it here: https://ift.tt/2DNannd tested the logic, and it works fine, the problem however is that it looks like a script, and I'm guessing this can be done better.

Seems to me that managing migrations and having them in source control is one of knex's best features while still letting the user use raw queries if needed. A simpleknex migrate:latest can then update your schema painlessly on your production server. How do you guys do it if you don't use this?

Node Js with angular front end, best way to integrate file uploads and downloads
HiI have a process where i receive a set of documents on an sftp, server and then move them into my internal filesystem and log them in excel. This is time consuming. I have been developing a system to streamline this whereby I receive a list of the documents received and put that through my system which will log the documents in a database and then automatically move the documents from this sftp server to cloud storage. I am not really sure what the best cloud system to use is. I do not really like S3's node SDK but it seems like the most commonly used system. I am also not sure how to go about moving files from the sftp server to S3. Would be looking for some ideas on how to best implement the flow of files from the sftp to a cloud provider. I will need to be able to download the files at a later date.Thanks

Question. Handle one event at a time.
So, lets say I have an event with a bunch of listeners. But among those there is one special - it is async, and, if this event is fired while previous special listeners are still not finished, I want it to wait for that previous listeners to resolve. So, these listeners can only work one after another. In the end, I came up with this thing:function queueify(handler) { handler.queue = []; handler.locked = false; async function dummy(...args) { handler.queue.push(args) if(handler.locked) return; else { handler.locked = true; while(handler.queue.length) { args = handler.queue.shift(); await handler(...args) } handler.locked = false; } } return dummy; } While it works, it looks over-complicated, I am sure there is a better way to do my task.

Node.js clustering
I'm starting to work with node.js, so have a few general technical questions about the clustering.What I understand is that a Node.js instance uses one CPU core. This means that I can start 8 instances of the same Node.js application on a computer with 8 core CPU, correct?That means if I want to start more than 8 instances I need another computer?How much HTTP request can a single node.js instance handle very roughly?If I do not use a monolith but a microservice system with about 100 microservices, could I only start 8 microservices per computer?If I start each Microservice in its own Docker container I could start any number of services on a computer (depending on the available resources) or are the containers also bound to the number of CPU cores?Thanks for your help

Structuring a Class for a third party API with Node.js/ES6?
Hey guys, I'm trying to restructure a small app I'm building. I'm using Spotify's API and at the moment I have all my logic in one file and just creating the routes there. I want to create a class for SpotifyClient and another class for my server but I'm unsure how to go on about this. I have these two routes specifically for Spotify Authorization that I want to remove and put into a class:app.get('/login', (req, res) => { const state = generateRandomString(16); res.cookie(STATE_KEY, state); res.redirect(spotifyApi.createAuthorizeURL(scopes, state)); }); app.get('/callback', (req, res) => { const { code, state } = req.query; const storedState = req.cookies ? req.cookies[STATE_KEY] : null; if (state === null || state !== storedState) { res.redirect('/#/error/state mismatch'); } else { res.clearCookie(STATE_KEY); spotifyApi .authorizationCodeGrant(code) .then(data => { const expiresIn = data.body.expires_in; const accessToken = data.body.access_token; const refreshToken = data.body.refresh_token; // Set the access token on the API object to use it in later calls SPOTIFY_TOKEN = accessToken; spotifyApi.setAccessToken(accessToken); spotifyApi.setRefreshToken(refreshToken); spotifyApi.getMe().then(({ body }) => { SPOTIFY_ID = body.id; }); res.redirect('/search'); }) .catch(err => { res.redirect('/#/error/invalid token'); }); } }); I have my API keys that I export as environment variables and store them in an object in a config.js file.So starting out, would be somehting like this:const config = require('./config'); class SpotifyClient { } But would I pass the keys in my constructor? How would I set up the routes? Should they just be class methods?Any advice would be appreciated!

Inmemory-like database in Nest
I've started learning Nest recently and I've come up with a simple game based on websockets and there's a problem that I have to face now.There is A service that handles every fetch API requests with room creation etc. and then there is websocket gateway that handles the room on anything that requires data-sharing between players.So I need to access the same data structure that I've implemented for Room and that is an array. I'm not using any database.What I did was create state folder with state.module and state.service that handles everything that can be done with the room so like - creation, updating, new player etc. This state.service is then exported and imported in socket.module and room.module and injected (using Inject) into socket.gateway and room.service. This way I can access every method I've created in state and manage it accordingly. I was kinda okay with this but while rereading docs and hearing my colleague saying that it is not quite it and I'm not sure what should I do.Is it okay to leave it as it is or should I change it?

Email verification strategy with Node?
Would this be an OK way to implement email verification?1) Upon user registration, the user is created in the database with a field "verified" set to value "false". Another field "confKey" with a random string/hash as the value is also created in the user model.2) A message containing a link to an endpoint for email verification is sent to the user's email address3) That link contains a param which is the same random string/hash as the "confKey" in that user's data in the db.4) The endpoint compares the param to confKey and if they are equal, sets "verified" to "true".5) Endpoints that require a verified email check that "verified" is true before executing.Does this logic make sense? Anything I'm missing here? Security vulnerabilities doing it this way?

Detecting backspace in socket data (without key events; \b isn't working)
I'm writing a telnet server and I want to detect backspace without the client-user needing to configure their telnet app.The script handling keypresses and acting on data, receives the keypresses via net socket in realtime. So when the user makes a typo and then presses backspace, I'm trying this:else if (data.indexOf("\b") != -1 || data.indexOf("\u2408") != -1 || data.indexOf("\u0008") != -1) { // handle backspace console.log("Backspace detected"); this.currentInput = this.currentInput.substring(0, this.currentInput.length - 1); } There's gotta be a way to do this without access to key events, right?EDIT: updated source and added this note: the console.log("Backspace detected") never happens, but also the test data contains no garbage characters; just the typo plus the correction. E.g. if I type tesd(backspace)t into the terminal and hit enter, the server receives tesdt.EDIT: updated source again, still no luckEDIT: the data isn't being manipulated: this.socket.on('data', (data) => { this.onSocketData(data); });

Hey guys, I'm a front end developer (html/css/js mainly), and I wanted to dive into node/angular. I started a new project, and wanted to play around with the Destiny 2 API. I found a npm package that is apparently a wrapper for the Destiny 2 API called the-traveler.So in my new project, I went to app.component.ts and pasted in the import/const:import Traveler from 'the-traveler';import { ComponentType } from 'the-traveler/build/enums';const traveler = new Traveler({ apikey: 'pasteYourAPIkey', userAgent: 'yourUserAgent', //used to identify your request to the API});I do have an API key, but I'm not sure what goes in user agent, so I tried a few things - didn't seem to get any errors caused by that (that I know of).I then served the application and opened it, but I got the error that it failed to compile, along with all of these errors:ERROR in ./node_modules/aws-sign2/index.jsModule not found: Error: Can't resolve 'crypto' in

few other destiny api wrappers and they are all giving me the same errors, so I'm just assuming I'm putting the code in the wrong place lol.I'm using the most up to date versions of everything as well fyi. Any help would be greatly appreciated.

What is the scalable approach for executing post tasks regarding on specific operation?
I'm working on B2B microservice platform. The scenario is to buying and sell product from one business to another business, I meant not a person to business like e-commerce. When one business order product from another business I've to send invoice over email, mobile SMS, push notification etc to both buyer and seller business employees (each business can have multiple employees).So what I'm doing now, when an order created I'm fetching employee information related both buyer and seller business from another service by API call and calling another service over API to send the invoice over sms email etc based on user preference. same for update the order.when demand increases as it's the basic feature of this platform sometime seems it slows down the ordering process. Here I'm using expressjs , mongodb in backend on ubuntu VM.Should I use any message-broker to handle those task? or another worker (child) process to handle them? whats your suggestion and how should I go forward?
