Hi everyone, sorry to bother you today but I am part of a boot camp and they teach us Node/Express sqlite3 and knex. I love Node, Express, and knex but I found out sqlite3 was horrible for production and etc so I am trying to figure out how to create a postgresql database and connect it to knex. I have searched Udemy and google and the google searches all date back to 2015. I was hoping someone here may know of a good tutorial for this? I tried the documentation and it is not the most new user-friendly. Thank you for your time.

Can you suggest app's best database structure to store thousands of users entities ( MongoDB ) ?
I'm making a forum, with chat system and upvote/downvote system. Could someone suggest best way to structurize database, for best optimization to handle thousands of users ?I have several sections to think about:- Chat ( messages and dialogues ). In my case I'm just made two collections for dialogues and messages.- Upvotes, Downvotes. I'm storing them inside users record, in "upvoted", "downvoted" fields arrays.Also I will apreciate if you advise best practicies for app's database structure. Thank you!

EONET error when I can see the file it says is missing in it's folder!
I'm trying to learn node.js using this program and I'm super stuck at asynchronous I/O. Specifically, I'm using fs.readFile on a file named number.txt (saved in the same directory I'm currently in), and the code is running, but when I console.log(err) it says [Error: ENOENT: no such file or directory, open 'C:\Users\myname\javascripting\number.json'].I have a file named number.json saved in the path, C:\Users\myname\javascripting so I don't know why the program can't find it.My code aio.js:var fs = require('fs') var myNumber = undefined function addOne() { fs.readFile('number.json', function doneReading(err, fileContents) { if (err){ console.log('fuck'); console.log(err); } else{ myNumber = parseInt(fileContents) myNumber++ console.log(myNumber)} }) } addOne(); The result when I run in the console C:\Users\myname\javascripting> node aio.js :fuck{ [Error: ENOENT: no such file or directory, open 'C:\Users\myname\javascripting\number.json']errno: -4058,code: 'ENOENT',syscall: 'open',path: 'C:\\Users\\myname\\javascripting\\number.json' }edit: I've tried the same thing but with number.txt as well

How am I supposed to make a timer_
Well, first of all I want to tell you what I am trying to make.Basically I am making a monthly subscription monthly paying but I don't know who to check that the user paid again.I thought in making a scheduler for each user and after the scheduler is done, check the database or something. The end date would be saved to db in case a shutdown, so I can retrieve the information again to start the scheduler again.I hope any of you know the correct way to make this.Thanks.

Help with massive streaming data approach
Hey all!I’ve developed a node system that pulls data from multiple high traffic websocket channels, and am running into a backpressure problem.On each websocket payload receipt from various classes that talk to the websockets, I emit an event with said payload, the events then being received by a single class that then pushes the message payload onto a stream. This stream is then piped to another stream that throws the message onto a Kinesis stream via the kinesis-streams package. I did see that the author of that package switched to Kafka but thus far I’ve been happy with it and fine with the java dependency.I believe the backpressure and resulting crash from being out of memory is the stream that is piped to the Kinesis writer. The Kinesis writer is batched though, and have tried a highwatermark at various levels; same result. My questions:1) is emitting all the websocket messages as events (to be received by the single class) a bad idea? Am I possibly filling up the event bus? 1a) should I just expose the input stream to the websocket pulling classes instead of emitting as events? Can multiple classes write to a single input stream?I’ve been googling all over the place but haven’t really found another case of a successful massively high traffic data stream implementation in node.. just others with similar problems.Thank you!

Can a stream piped into process.stdout() destroy it? Is there a way to restart process.stdout?
I'm starting a child process and piping his output into process.stdout, and somehow sometimes the console goes silent and not even console.log() works, so my guess is that stdout is being destroyed.After a lot of troubleshooting with the limited data I have, I arrived at the conclusion that the stream termination seems to happen when the child process spits "™".Setting the end parameter to false did not help:this.fxChild.stdout.pipe(process.stdout, {end: false}); Do you guys have any ideas on how to prevent the stream termination without having to modify the data?

How to specify NodeJS 'child_process' dependencies / version?
I have a full stack web application with a React frontend and NodeJS backend. I'm using child_process to spawn a python process that calculates some values then returns those values to the JS parent process via print lines. This all works as expected.The issue I'm having, or moreso my area of confusion, is where does the child_process script get it's PY source code from? I suspect that child_process is currently taking the PY version local to my machine somewhere in usr/bin (I'm on a Mac Air 10.13.2 if that matters)I'd like to be able to specify the python version and have all dependencies/libraries installed inside of the server directory, so that I have them available to the PY process when the server is deployed- as opposed to the PY process just using whatever is on my machine.I've looked into implementing some sort of pyenv but I'm confused as to how I can execute PY processes from my server application from Node in such a way that they refer to packages inside the server for source code and external libraries.TLDR: How can I use child_process in such that it's child process refers to something like node_modules for dependencies.// how I call the child_process spawn functionlet py = spawn( 'python', ['path_to_py_file', arguments])// normal handling of input/output

Callback Functions - How do they actually work?
I'm a little curious about something, being new to full-stack development. I've written a lot of MATLAB tools, FORTRAN processes, and C/C++ and assembly doing embedded system develoment, but this concept is very new to me.When I use express and pass a callback function to a route like:appRouter.get("/", function (req,res){ doSomething(); } how are the parameters "req" and "res" actually passed to the callback? I'm declaring the callback function, and somehow also passing those objects through to that function's execution context?Also, when retrieving data from my controller/model, I have to pass a callback function to the asynchronous query method, which somehow has a response object already embedded in it?How is all of this working, beneath the scenes? Is there an analogy or description that might help me understand how all this works?Thanks in advance.

Question about synchronous functions and blocking behavior
Hi Everyone,I'm using express for a little web api and I was wondering how exactly a synchronous operation would block the node process.Let's take that simple code :const express = require('express') const app = express() app.get('/route1', function (req, res) { res.send('Hello route1!') }) app.get('/route2', function (req, res) { someHeavySyncFunction() //Let's imagine this function is synchronous and take 2 min to complete res.send('Hello route2!') }) app.listen(3000, function () { console.log('Example app listening on port 3000!') }) Would my route2 block the entire node process and therefore preventing people to access my route1 until the function ends ?Thank you

Examples of Well Structured NodeJS Websites
I’ve been learning NodeJS (and web dev in general) recently and I noticed my structure of my website is okay but could use a ton of improvement.Being a self taught programmer, I’ve never really been around experienced devs to learn from them so most of my toolset comes from YouTube and Stackoverflow. However, I’ve recently noticed by code feels like it’s kind of all over but I don’t know the best way to fix it.I know the usual separation of controllers, views, etc. but I’m having trouble applying OOP to JS specifically.Does anyone have any example repos of well executed oop using Node that I can review to try and learn from?

What does it mean to build an API?
I see in many job offers, that they require developers to have experience building RESTFUL APIs. What does it truly mean to build an API? Is it building APIs for other people to use, like Google maps etc, is it the same as routes we see in express? Some elaboration would be deeply appreciated!

Help a N00B build an E-Wallet App
I am creating a project with User database and identification (email)/(password) log in and sign upWhen the user Signs up for the first time, he creates inside his account a Wallet, the wallet automatically assigns a Random Identification Number just for the wallet itself. Inside the wallet "credits" are stored. The start up value of the credits will be 0 for some users and for lets say premium users will be 20 credits.Then I need those wallets to communicate, lets say User 1 has Wallet A and Wallet B, User 2 has wallet C and wallet DUser 1 can send "credits" from his wallet A to his wallet B and viceversa, also User 1 can send credits from his wallet A to wallet C or D from User 2.BUTUser 1 cannot send "credits from wallet B to wallet C nor D from user 2User 2 cannot send "credits" from wallet D to wallet A nor B.the "credits" being transferred as a encrypted "message" for speed and each transaction stored in an encrypted database.At the end I would need integrate the project into swift so it can run as an iOS App, and then later to Java for Android OS, also need it to run on a website.Thank you for any assistance and help in advance.

Learning Go as a Node developer
Hello guys,Not sure if it fits here, but after writing and teaching a lot about Node and hearing Ryan Dahl's thoughts about Go I dived deeply into it and I think it is worth the time for us Node developers to broaden our view and learn it too.https://blog.risingstack.com/golang-tutorial-for-nodejs-developers-getting-started/In this post I tried to cover my experiences as thoroughly as possible about the basics of setting up a Go development environment and writing a simple "Hello World!" server with net/http, encoding/json, kelseyhightower/envconfig and about Go's dependency management.What do you guys think? Is it helpful at all, should I continue with the series? Also if you've already started writing Go code, what are your experiences? For me, I like it so far, only when I wrote some low-level programs for hardware management on Linux, testing was way too cumbersome.

How to import from project root (instead of package root)
I'm creating an npm package and I want the user to be able to set configuration files in the root of their project. An example structure might be:- UserProject/ - index.js - config.js - package.json - node_modules/ - package/ - index.js - package.json Inside UserProject/node_modules/package/index.js, I want to be able to import the file UserProject/config.js.I know I could use import config from "../../config.js" but that doesn't seem like a good way to do it.I know many other npm packages are able to do this so I'm wondering how they achieve it. A few examples that do this:Next.js is able to read ./pages/ and ./next.config.js from the project rootJest is able to read ./jest.config.js from the project rootESLint is able to read ./.eslintrc.js from the project rootPrettier is able to read ./.prettierrc.js from the project rootTypescript is able to read ./tsconfig.json from the project rootBabel is able to read ./.babelrc from the project rootI've tried creating a StackOverflow post but got no replies, I've tried googling for it but all I get are results on how to do basic es6 imports, and I've tried looking at the source codes for the above examples but I can't locate the sections on how they do it.Any tips?

How to do I know the correct URL to like/unlike a comment in MERN?
First of all, I'm sorry if this is not the place to ask. I will delete the post if requested.Let's say I have the following URL:http://localhost:3000/demo/_idInside that URL I have the entry for said _id and some comments which can receive likes by the user. How can I know what's the current URL to like the comments? Assuming I can already like the parent _id(the entry). Here it is an image of my MongoDB database:MongoDB Test DatabaseAs you can see in the image above there's a field called likes in the comment. My question is how would I go to make it like-able?.This is what I have in my actions file for liking the entry. Can somebody guide me and tell me how to edit it to like X comment found in the entry?:https://i.redd.it/r7yno0wrnm631.jpgAnd this is what I have in my API route(again this is for X entry; how can I edit to like a comment):https://i.redd.it/75h6l7vsnm631.jpgHopefully I could explain myself well enough and thanks for bothering!.

I am trying to work with TextBroker's API and it's in SOAP.At the bottom of page 13 in the docs they are referencing passing in an array to the client which soap.createClient doesn't support. I can access the SOAP WSDLs on some and .describe() properly, but all requests come back as not logged in even though I send the proper arguments in the request.It looks like it's wanting me to do the doLogin client (wrapper) and then inside do another client for the individual SOAP clients I need.Sorry if I am explaining this poorly, but I am so used to just talking within a REST environment.

Node performance questions
Hi all,Intermediate node dev here, have a few questions about debugging/measuring performance of nodejs apps.Some general questions:Is there an option or flag I to see what the garbage collector is doing or where/when memory allocation is happening, gc pauses etc.Is there a way for me to print out the assembly the v8 compiler generates?To time the code I can just use a timer and run my function or app in the timer 10k times or something, I guess, is there a better way to do this?More specific ones:(Hypothetical question) Say I have a .csv file with 100k lines. I parse each line in a loop and create an object with a key for each column in the .csv and a value for each row entry in that column.Now i am making 100k objects in a short amount of time.Say my csv header looks likeid, name, location, email, address, phone, number, tags My 100k objects would look something like{ id: UUID name: "Frank N. Stein", location: {lat: 3, long: 1415}, email: "whatmeworry@gmail.com", address: "123 Elm St.", phone: "123 123 1234", number: 1, tags: ["blah", "other tag", "another tag"]} They keys would all be the same but the values are different for all the 100k rowsIf I create a new object for every row, I would be creating 100k objects, what happens if I use an object template like:{ id: UUID name: "Frank N. Stein", location: {lat: 3, long: 1415}, email: "whatmeworry@gmail.com", address: "123 Elm St.", phone: "123 123 1234", number: 1, tags: ["blah", "other tag", "another tag"] } and for each row modify the values liketemplate.id = "fdfdf" template.name = "ur mom" then write the template to a file before processing the next row.Will v8 allocate one object and change the pointers for the new values or will it copy the original? And how can I learn about how this works and see it in action ?I am streaming a file larger than the available memory on my machine :For each chunk of data that I stream I make an api call and add it to a promises array.I set a batch size of a 100 for the promise array and once I get to a 100 I await all the api calls.(I don't know how many open sockets I have on the open pool so I don't know how many requests are in flight at the same time and how many are queued. Is there a way to check this? I just chose 100 as a nice round number for this example.)Now my code will pause during 2 cases:When I am awaiting for the resolution of all the promises ( I don't know if the stream keeps reading during this time, I don't think so because my await Promise.all() is inside my stream's on.data event handler.When the stream pauses to let the consumer consume more data on the stream because of backpressure.My whole stream is wrapped in a new Promise() which resolves when the stream.end's or rejects if the stream.errors.Say I want to process 100 such stream in parallel? And i just do something lilke(async () => { const promises = {} files.forEach(file => { promises.push(streamFile(file)) } await Proimse.all(promises) } )() What's happening? Is node processing each stream in sequence, is is processing multiple streams at the same time (some chunks from stream 1, some chunks from stream 2? ) How does this work?Am I thinking about this stuff correctly? How do I see whats going on "under the hood"?Any resources that have any of this info would help me a lot I just couldn't find anything.Sorry for the long ass question, thanks!

Empty response from mysql query - async callback question
I am writing a small app and trying to query all the users from my mysql database. I'm new to nodejs, express and mysql. I'm able to execute queries, but I am having trouble returning the value of the query to the browser as a json object, using postman.Here is the code for my userRouter.js file:const usersRouter = require('express').Router(); const userController = require('./usersController');usersRouter.get('/', function(req, res, next) {var testObject = userController.getUsers();res.json(testObject);});module.exports = usersRouter;And here is from the userController.js file:const db = require('../database/db'); exports.getUsers = function(callback){var allUsers = db.query('SELECT * FROM users', function (err, rows, fields) { if (!err) { if (rows) { callback(null, rows); console.log("userController.getAllUsers - completed query") } else { callback(err, null); console.logo("userController.getAllUsers - error performing query.") } }}) }I obviously get an error that says "callback is not a function"...The reason I have ... function(callback){ .... written like that is because that's what I"ve seen online in forums and answered questions. It doesn't make sense to me to just have "callback" defined as a function parameter, then called later in the function body because the function isn't defined, but nearly every example I see online on how to solve this problem writes the solution in this manner.What is the smart way to return the response from the query? I know I need to "use a callback" function to do it, I just am not quite sure how.

Process communication: event listeners vs http requests
I'm using PM2 to scale up my app and I've added some code to handle communication between the processes.I'm using a lot of `process.on` and other event emitter driven actions, but since I need req/res like flow, the code is starting to feel like spaghetti.If I need to share data from one process to another, is there a big reason to go with process communication rather than just exposing http endpoints?I feel like my code would be much more straight forward to have some express routes, and then make req to localhost than to have all these event handlers everywhere. Also seems easier to test...Thanks in advance for any help!

This is what I have understand about single-thread and synchronous. Do i'm right?
JavaScript is Single Threaded and has Synchronous execution model. Single thread means execution commands run on a single thread and executes one at a time, I imagine as ants marching. i.econsole.log('print1'); console.log('print2'); console.log('print3'); // Output print1 - runs first print2 - runs second and so on. Synchronous means execution command executes (runs) and wait until execution finishes/returns and move to next command. i.efetchUser(); fetchPosts(); // fetchUser() executes and waits until user list return and moves to fetchPosts(); If I have understand it wrong, please comment below

Never knew importance of String.normalize function. Where should I be using it?
I'm surprised I never knew the importance of String.normalize function or even heard of it. I'm trying to figure out where it goes in the application and it looks like it should be used everywhere I accept user input?How are you using String.normalize throughout your apps? Seems like it would be easy to forget to use it somewhere I need it because of all the places it needs to be.Which of the 4 normalization options do you choose and why: NFC, NFD, NFKC, NFKD? https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/normalize#Parameters

How to get local variables to be recognized by express-handlebars?
Forgive me I don't really know if I'm asking the question the right way.I'm using express-handlebars. I have some views that have forms. On those forms I would like to conditionally add extra text columns if certain form options are selected. I understand that I can pass an object in my res.render() function.ie.router.get('/admin/add-race', (req, res, next) => {res.render('admin/add-race', {layout: 'admin',path: '/admin/add-race',pageTitle: 'Add Race Info'});};I could pass in something like isCertainFormOption: false how would I change that to true in the view itself if a form option is selected?

Difference bw/ Front end framework and Node view engine?
Hi all, I’ve just started learning real web development and am learning about Node and React, Vue, etc. So generally speaking React and Vue are used to display client-side markup while Node is used for backend services and making database queries. So upon watching videos on YT, a node tutorial was describing setting up a view with EJS and that includes an HTML template as well as Routing for different pages in the application. I was confused by this because I would expect this to be reserved for front end frameworks like React. So the tutorial finished creating an app with pure Nodejs (mind you it was a simple application), but that made me question what the point is in using Node vs React to create the client side view. What is the difference? Is it the same thing, only that it’s best practice to separate the back-end with the front-end by using different frameworks? Thank you! Apologies if this is a simple question, I am only beginning my learning.

Issue trying to test a http request in a setInterval
Hello, I use Typescript and a class to manage a feature that I'd like to test. This is my simplified code:class Feature { private _names: string[] = []; constructor() { this.fetchNames(); } private fetchNames() { setInterval(() => { MyAPI.getNames() .then(names => this._names = names) .catch(err => console.log(err)); }, 1000) } get names(): string[] { return this._names; } } I use a class to manage my feature but I guess I would have the same problem using a module and functions, because only the names() function would be exported, fetchNames() and _names would be private.I'd like to test after the first request the names() method returns the correct names. What I tried:describe(`Feature`, () => { let clock: sinon.SinonFakeTimers; beforeEach(() => { clock = sinon.useFakeTimers(); }) afterEach(() => { clock.restore(); }) it(`Should update the names`, async () => { sinon.stub(MyApi, 'getNames').resolves(['Alfred', 'Eve']); const feature = new Feature(); clock.tick(1500); expect(feature.names[0]).equal('Alfred'); }) }) The request is called once and returns the correct names, but I got this error: "AssertionError: expected undefined to equal 'Alfred'".It'd like to let the _names property and fetchNames() method in private. Thanks for reading, any help appreciated.

How to communicate with a C-written subprocess ?
I hope it's ok to post questions like this here.In NodeJS (using Electron, so console.log goes on the window console), I want to spawn a child process that's a C program, and read/write into its stdio to communicate.This is the Javascript :const { spawn } = require('child_process'); var utfEncoder=new TextEncoder("utf-8"); var utfDecoder=new TextDecoder("utf-8"); var process = spawn("./src/test-c"); process.stdout.on('data', (data) => { console.log(utfDecoder.decode(data)); }); model.send = function(s) { model.process.stdin.write(utfEncoder.encode(s)); } And the C :int main() { char buffer[100]; printf("ready !"); fflush(stdout); for (int a = 0; a < 100; ++a) { scanf("%s", buffer); printf("I read: %s", buffer); fflush(stdout); } return 0; } And the "ready !" never appears anywhere. But it works when the program only prints a message every second :int main() { for (int a = 0; a < 10; ++a) { printf("ready !"); fflush(stdout); sleep(1); } return 0; } With this program the message "ready !" appears every second on the window console, but with the first one nothing happens (not even the first message before scanf).What am I doing wrong here ?

Issue with Horspool algorithm request parser
I've been working on a rebuild of my API generator; Multicolour, and I've tried a few modules that do request parsing using fast string searching algorithms but they either don't test very well or don't search the entire text for all the occurrences of the pattern.So I built my own which works for just about every payload I throw at it (both static and randomly generated data) but every now and again there comes a payload (which I then add to the static list to test) which trips it up.I'm now complete stuck on the latest trouble payload and I think there's a small detail I'm missing in my algorithm. I've read all kinds of papers on it, other libraries that do the same thing but I'm totally stumped. I've asked this question on Stack Overflow but it didn't seem to hit the audience. I'm happy to offer a bounty over there for it. I've actually fixed it for the payload in the question but there is a new payload causing issues.Stack Overflow questionSource codeTest Source code with payloads

API Gateway and Microservices question
Say I work for a company and there are many brands under the company. I have microservces such as userService, emailService, reviewsService, etc.So if I go to a specific brand's website and subscribe to its newsletters, then first I will need to send requests to the API gateway and it will direct me to the database of that particular band. API Gateway will authenticate/authorize if I'm already a user and if I'm authorized to subscribe, etc. Then, API Gateway will serve as an entry point and looks up the microservice (subscribeService) which can serve the request and delivers it to relevant part. Is this the right approach? Would be great if you could explain the whole architecture and flow? Thanks!

How to ensure someone logged in can only trigger SQL queries relevant to that user?
Hey guys I have a bit of a conceptual block here.The webapp I'm building will let users login, and add stuff to their "profile".My question is how do you ensure that user 123 is only able to send queries using their ID as a user ID? In theory you can't fully trust anything the user has control over, cookies, React states, etc.While a user is logged in, is there some way to store authenticated session variables in the backend or something? That way instead of getting the "user id" variable to use in queries from something the user can edit, it's from a secure place that authenticated them to use that user ID.Or am I just overthinking this?

Node framework for microservices?
Hi all,I'm trying to design an app using the microservice architecture. Ideally, the services would communicate with each other with TCP sockets (not a REST API, as I need pub/sub). What's the best framework to use for the services? I could write the code for the TCP sockets by hand but I'd rather spend my time coding the actual features of the app.The frameworks I've found so far are cote and Nest. Nest seems very feature-rich and possibly too complex for what I'm trying to make, whereas cote only focuses on microservices and seems more lightweight. I've been trying to find some opinions of people using these frameworks in production apps, but I couldn't find anything. Has anyone here used these frameworks or other ones for microservices? If so, what do you think?

How do you handle thread blocking if you’re running multiple node instances in Docker?
Hey guys, full disclosure, I haven’t worked with Docker and I’m still new to node but I’ve read a lot about both and I’m getting my project rolling.The way I understand it is you can use Kubernetes with Docker to add a lot of scalability to a project by spinning up multiple instances of whatever micro services you need. I think Kubernetes handles load balancing?If my server only has X cores, I’ll always only be able to run X threads simultaneously for async tasks. So what’s the benefit of running multiple load-balances instances with a container based solution? Technically you’ll always be limited by your threads so how does that help with scalability?

Nodejs Proxy Server Pointers Needed
So i have been creating basic node APIs for some time now. And I was thinking about creating a Node Proxy server to learn more. Could you guys give me some pointers on how to proceed on this one ?What I was thinking of is create a end point on the server which takes a parameter like a url and fetches the url document body or something of the sorts in the controller and then return the html or response body. Would that work ?Thanks in advance for your help

How do I prepare my database for tests using Jest and Knex.js?
I'm trying to write some integration tests for a RESTful API I am writing in Node.I want to setup a test database so that I can can call my API endpoints with Supertest and assert that the correct data is returned.My Jest global hooks are as follows:const knex = require('../../db/setup'); beforeEach(async () => { await knex.migrate.rollback(); await knex.migrate.latest(); await knex.seed.run(); }); afterEach(async () => { await knex.migrate.rollback(); }); The setup file is as follows:const { Model } = require('objection'); const Knex = require('knex'); const environment = process.env.NODE_ENV || 'development'; const configuration = require('./knexfile')[environment]; const knex = Knex(configuration); Model.knex(knex); I currently have two test suites, each with a single test, if I delete my test.sqlite3 file and then run my tests I get one passing test and one failing test, with the following error:SQLITE_ERROR: table `knex_migrations` already exists If I then run my tests again I receive a different error:MigrationLocked: update `knex_migrations_lock` set `is_locked` = 1 - SQLITE_BUSY: database is locked How can I get the database to reset correctly between tests, is there a better approach to doing this (e.g. is my attempt to reset the database between tests incorrect), should I be doing it on a per test suite basis instead?

Node.js/Express performance and best practices: Should I make multiple calls or just one big call?
I have an express server that needs to write about 100 html files into a directory in the project root.I can build this server in 2 ways: the server can receive the request from the browser then start the 100 requests and send back a 200 when it finishes, or I can send a 200 after every successful file write and just go back and forth like that for every file.My question is, when using express/node.js, which is better performance wise?In scenario 1, should the server just be sitting there doing all that work for multiple users? Will I run into memory issues? Because I could put that list of files in the browser and make separate calls to my node server to retrieve and write each file from the external API.This is what that first scenario sort of looks like. The route gets a list of files, then makes a call for each file.//this whole request takes about 3 minutes to complete due to rate limiting of the external APIs. router.get('/api/myroute', (req, res, next) => { //contact a remote server's API, it sends back a big list of files. REMOTE_SERVER.file_list.list(USER_CREDS.id).then(files => { //we need to get the contents of each specific file, so we do that here. Promise.all(files.map((item, i) => //they have an API for specific files, but you need the list of those files first like we retrieved above. //more specifically you need a key for each file that is in the file_list object. REMOTE_SERVER.specific_file.get(USER_CREDS.id, { file: { key: files[i].key } }).then(asset => { //write the contents of each file to a directory called "my_files" in the project root. fs.writeFile('./my_files/' + file.key, file.value, function (err) { if (err) { console.log(err); }; }); }))) //send back a 200 only when the entire list has been retrieved and written to our directory. .then(() => { console.log("DONE!!"); res.status(200).send(); }) }); });

The only differences between my code and the one shown in the README, is that I've changed the variables to make them specific to my environment (i.e. bucket name, /tmp folder to locally store the zip archive, etc.)I'm running the code on AWS Lambda and the on close events are not being triggered. Does anyone have any ideas as to what I'm doing wrong?

Socket.io and socket properties
Hi, I a beginner in node and socket.io. Working on the chat to get some experience, I want to store my users names in an array for later use.On the client side I get a string from user input and store it as a name and then I add a property to my socket : Socket. nickname = nameAnd on the server side I have:``` io.on('connect', function (socket) { console.log(socket.nickname != undefined);if (socket.nickname != undefined) { console.log("here") connectedSockets.push([socket.id, socket.nickname]); socket.arrayIndex = connectedSockets.length - 1; console.log(socket.arrayIndex + " " + socket.nickname) console.log(connectedSockets); } });```The problem is that it will print the line only once:console.log(socket.nickname != undefined);And not enter the if once the nickname has been set. I’m obviously missing something there, could you give give me some advices to solve this? Thanks

"Separating UI from Service Logic" in Node
Hi Guys,I am new to Node and Web Dev in general. At work (IT dpt of a manufacturer) I am responsible for developing a prototype of a web application that we want to offer to our other departments. We have now started the conversation of what we would need to change or add to make it production ready.One of the guys (he's been in IT for a long time but I don't think he has done much in Web Dev or with Node for that matter) had a quick glance at my project structure and said "You are mixing UI with service logic, and will need a separate web server between the browser and the Node.js server".I am really struggling to understand this and when I asked if he could elaborate he just started to use some terminology I am not familiar with and mentioned that having the app server serving the views would be the standard of 2005.The basic architecture of my app looks like this:Express as Web Framework that handles requests and routesejs as my view / template enginemongoose for DB queries to the underlying Mongo DBFor Front-End I use vanilla JS and very little CSS as I am leveraging Materialize CSSThe App has in theory a very simple scope (the bigger challenge will be to get the correct data from our ERP system) and consists of a handful routes and views. I was able to cover all the UI elements in plain HTML (i.e. ejs) and as such I did not find it necessary to use (and learn in my case) a heavy weight frontend framework like Angular or React.With all this information provided, can you guys help me understand what those statements could mean and more importantly if I am following a bad practice with this architecture?My understanding of Express and view engines like pug or ejs was that they exactly do what that other guy is saying that I should not do: getting requests from the client, doing some DB queries or calling services from our ERP and serving the corresponding views based on the response.The reason I ended up learning and using node for this project to begin with was that after some research I found out that node seems to very good for handling exactly our use case due to its asynchronous and non-blocking nature: be able to handle requests that require you to do something "in between" (ie DB queries or service calls to ERP) whilst not blocking additional client requests.After that conversation I am now starting to doubt if I missed a critical part in my learning and developing journey so far and would like to get your opinions about those statements and my understanding of node.Hope my issue is somewhat understandable. Any input is much appreciated.Thanks

Authentication Logic - React Native <-> Node
Hey,I am developing a little app on React Native, using Node as a Backend (w/ MongoDB). On my app there is 3 ways of register/login: Google, Facebook and normal way inserting Username and Password desired.On front-end side, on React, I am using OAuth to login on Facebook and Google, sucessfully and getting a token, which I am storing on MongoDB. If the User chooses to use the normal way, I generate a token, store it and send it to the User.At the same time, I store these tokens locally, so when I made another request to another node endpoint, I am sending also the User_ID and that token, so I can validate the User before returning something.Is this correct? Am I doing this too basic?Thanks in advance

Node/NPM, Windows, and Permissions Errors.
Hello /r/node,My apologies if this is not an appropriate place to post this. Recently at work due to security requirements I had to switch away from Arch Linux dev laptop and start using a Windows OS. This is fine as I am fairly familiar with Windows, however I am NOT familiar with Windows permissions.I installed the latest LTS for Windows. Made sure it was in my path. So I can use node/npm from CMD/Powershell/CMDer etc. However I run into some fairly annoying permissions issues.The first issue is when running ng build --watch with nodemon within an Angular project I will get this error:> concurrently --kill-others "ng build --watch" "nodemon -e js,html,json,ts,map server.js" [1] [nodemon] 1.19.1 [1] [nodemon] to restart at any time, enter `rs` [1] [nodemon] watching: *.* [1] [nodemon] starting `node server.js` [1] [INFO] Running on port: 5000 [0] ENOTEMPTY: directory not empty, rmdir 'C:\Users\user\Dev\admin\dist\admin\assets\fonts' [0] Error: ENOTEMPTY: directory not empty, rmdir 'C:\Users\user\Dev\admin\dist\admin\assets\fonts' [0] at Object.rmdirSync (fs.js:684:3) I can get around this by deleting the `dist/` folder and all it's contents EACH TIME before I run the project. However I shouldn't have to do that, and certainly never had to on Linux/OSX.The other issues are basically any IDE I end up using I can't run the project from the built in terminals, or run their debuggers as they almost always hit a permission issue in the `node_modules` folder.npm ERR! path C:\Users\user\Dev\api\node_modules\propex\package.json.3101012362 npm ERR! code EPERM npm ERR! errno -4048 npm ERR! syscall rename npm ERR! Error: EPERM: operation not permitted, rename 'C:\Users\user\Dev\api\node_modules\propex\package.json.3101012362' -> 'C:\Users\user\Dev\api\node_modules\propex\package.json' I have tried a few things, including looking at the project folders and opening the properties and trying to mess with permissions with zero luck. I have also popped open the linux subsystem and went with the nuclear option of chmod 777 -R ./* in my dev folder. Like I expected though this had no affect since windows doesn't do their permissions like Linux/OSX.tl;dr how do I fix permissions on my dev folder and subfolders in windows to allow my terminals and IDE's to access any of the files without permissions issues.

Has anyone written a *good* JSON pretty printer? Ideally in typescript.
We are working with typescript creating a new logging package, and would like logs to be pretty printed when in the development environment. However we have struggled to find a nice package to do this, especially one that has typescript typings.Any hidden gems that google is failing to turn up for me?Thanks

Recommended execution and authentication of Google Cloud Functions
I'm wondering what the best approach is for the execution and authentication of Google Cloud Functions.The requests will be exclusively from a Compute Engine VM instance, although this could change in the future.The functions themselves are for third party integrations, which will probably make use of a VPC for database connections.the idea I'm tossing around is to send an authorisation authentication request, which directly inserts a token into the db for subsequent use, but I'm wondering if there is a better approach for communication between CF and CE.Ideally I wouldn't be setting up instances of express as the functions themselves are fairly lean.The reason the functions are decoupled from the app inside VM is mainly for seperation of concern but there are other business/personnel factors.Thanks

Learning Curve of Nestjs without experience with Angular?
Hello Everyone,This is for anyone who has used NestJs. It has marketed itself as being inspired by Angular. For those who have little to no experience with Angular, how has the learning curve been with learning Nestjs?All of my experience is with Vanilla JS, React and Express. I'm contemplating learning Nestjs which has a more opinionated, structured, batteries included approach. Express though nice is too unopinionated at times for my liking.

Why is my function called twice?
Hi!My first interaction with nodejs is adding a function that sends a notification with a small payload to Slack when called. I have finally accomplished that! There is a small issue however is when I added my function to a script that handles datastreams, on the exit function dataStream.on('end'...) my function notification('Success!', message, destination)gets called twice. Either the exit function gets ran twice or only my function.Any idea why this happens?const _ = require('highland') const async = require('async') const { BigQuery } = require('@google-cloud/bigquery') const CIO = require('customerio-node') // init BigQuery const bigQuery = new BigQuery({ projectId: process.env.PROJECT_ID }) let queue = [] function queueProcessor() { async.eachLimit( queue.splice(0, 15), // take 15 elements (since most will have at least 2 calls 5, // 5 at a time processRow, // function that will execute the work, passed (row, callback) err => { if (err) { logger.error(err) } } ) } // Reset interval let queueThrottleProcessor = setInterval(() => { queueProcessor() // Process queue }, 1000) let dataStream = _( bigQuery .dataset(process.env.BIGQUERY_DATASET) .table(process.env.BIGQUERY_TABLE) .createReadStream() ) dataStream .ratelimit(15, 1000) .on('error', err => { logger.error(err) }) .on('data', row => { queue.push(row) }) .on('end', function() { // All rows have been retrieved. var message = `${numSynced} synced, total calls: ${totalCalls}` logger.info(message) notification('Success!', message, destination) clearInterval(queueThrottleProcessor) // Give 15 seconds for all the current processing to go through setTimeout(() => { // Done process.exit(0) }, 15000) })
