It's been almost 4years since I have been writing nodejs, it's been really cool, but at times - when starting a new project - I need to do the same things again and again, for example, adding eslint, prettier, GitHub, swagger, and mocha - All these are now sort of necessary for an app.So I simplified it for myself (and for you - it's public), I have created a nodejs API template on Github you can use it to create a ready to code like environment.Features:Express app optimized to make better APIsChanged structure to fit the API only use caseRemoved view and public folderAdded error handling without HTML/templating enginesAdded test route to understand the file structure and code splittingDatabase connection using mongoose, based on environment (production-ready)Environment variable to help you control the app environment using dotenvSwagger for API documentationPre-configured husky to run eslint and prettier on the pre-commit hook, helps maintain best practicesAutomatic versioning for apps on git push, using yarnTests pre-configured using mocha and chaiHere are things you can do:

Help with Node app idea
Hello fellows Node developers. I come here to day in search of advice on an idea that I have for a web app but I'm not sure how to tackle it.I want to create a server that takes a video, process it probably with machine learning to blur the faces that appear in it, and then store it somewhere.The part that I'm unsure of is what technology can I use to blur the faces of the video. I've read that OpenCV has some libraries for that, but I don't know yet how to implement it. I'm also not sure whether to use python to process the video but tackle the requests and everything with node (don't even know if this is possible, calling a python script from node) or to use the tensorflow library for node.I hope you can shed some light on the subject, any help will be very appreciated!

Sequelize Express - update belongsToMany associations?
Hello,I'm new to the forum, and in process of learning Sequelize :)I'm stuck with trying to update two models with belongsToMany association..For instance lets say I have User and Projects.I know that when you make the association, it creates these 'magic functions' like 'addProject', and 'setProject'. But how do you 'updateProject'?For instance, if I want to update the projects assigned to a user, then I would do user.addProjects(projectId).But lets say I want to update a user's project with an array of projects.Something like: user.updateProjects(['4','2','3']). How is that accomplished? Appreciate any input I could get.

Framework(s) to build a websocket API with OAuth2
Hi!Recently, I'm in charge of developing a side-project which should be a semi-public event real-time API which connects to my main project. Whenever an action happens on that project, we need to send an event to all connected websockets instances, more or less like Discord bots do with their websockets gateway.But that shouldn't be a public API at all - and we would like to keep diferent scopes for different users. Let's say that an official application uses this API with all scopes, an unofficial application but authorized from us shouldn't use all scopes but only the one we provide them, so basically we need OAuth2.Now, the problem is I never implemented an OAuth2 REST server; neither a websocket one. I only used it as a client. So I'd like a framework or a library which gets my work done easier, helping me learning to implement OAuth2.Also, I need a framework to which you can connect, well, module-agnostic, without using a custom built client. For example, I used socket.io some time ago for some private projects, and as I remember, you can't connect to socket.io directly without a socket.io client; you can't connect using browser's Websocket object. I need this because I don't know who my client may be and I can't force him to use specific clients.Also it'd be cool to develop in TypeScript, but that's a secondary thing for learning purposes.I tried the ws npm module, but seems harder than it should be to get things done just because I should implement OAuth2 from scratch.I tried Actionhero and it seems overkill for the project, to learn an entire new paradigm for something little as a small semi-public API with whitelisted access.I also tried Feather, but it seems to need a Feather client, or a socket.io client, and so it isn't module-agnostic.Thanks in advance for any help.

Send data from server.js node to the client
Hi everyone, i bumped into a problem, i have a website in which i would like the user to be able to uploads files, then i would upload those files to google cloud storage and then i would download them so that the app.js script can fetch and get the file data from them. I already managed to sort out how to store the files in google cloud and download them, however i realized thet sending the files so that the app.js fetch them cannot be done , at least with the frameworks that i am working with. I am using multer, when i was storing the files locally on my machine everything worked fine since the fetch function was able to access to that folder, however when i deployed it, i also learned that you cannot upload or at least you have no idea of the heroku directory, hence i cant upload there, also for security reasons. I have been trying to wrap my head around this problem and come up with solutions that dont involve install a new dependency or learn a new framework, i want to be done with it and move on. I thought about handling the file data on the server side and then importing the modules but i cannot do that since the server serves the js file as a text/html mime type. The directory looks like this:-main -server.js-complement.js( i thought about importing the module variable here first and then adding the src script to the html but i still get the mime type error).----public----app.js(Here the fetch of the file takes place, and where i wanted to import the variable from the server or the file)Hopefully i can get some guidance, thankss.PS: Im a bit burnt out btw, maybe later on ill come back and add more things

Why does MongoDB get so much hate? (Genuine question)
Recently I have completed my MongoDB Developer Associate Certification. I also have experience using SQL Databases like MySQL and PostgreSQL. My experience in SQL is definitely a lot worse than my experience in MongoDB but I still think it should be enough for me to understand the differences between them and that I would be able to compare them in a good way. But still, when browsing this sub I see a lot of people complaining about MongoDB and saying that SQL is superior. I read these comments and try to be objective but I still find that I disagree with most of the stuff being said, even though those comments get a lot of upvotes, this makes me feel like I don't understand why it is bad or bad in certain situations. Please help me see, I want to learn!In this comment for example. I know it is kind of a meme but it still gets a lot of upvotes and I know there are a lot of people who genuinely believe that MongoDB is useless for every single use case and is basically unusable in production.Also, a lot of people say the performance of SQL databases can never be matched by databases like MongoDB but I find that not to be true. I have been googling around for a bit but can't find any nice recent performance comparisons. I can remember some benchmarks on StackOverflow that were showing that MongoDB was a few ms off compared to some SQL queries. But MongoDB offers you a lot, I find that my schemas are less complicated which also saves development cost due to reduced application complexity.There are a lot of people who say stuff like:A non-relation database? What!! Almost every schema needs relationships, what a dumb idea this can never work.This does not make any sense of course MongoDB supports relationships, it would indeed be pretty useless if it didn't. The very fact that the type "array" exists in MongoDB means that it has relations. An array. by itself basically means a one to many relationship. Also, there is support for joins ($lookup) and that kind of stuff so MongoDB clearly supports relationships. I have also seen that people say that joins in MongoDB (or $lookup) is slower than in SQL. Like I have stated above, I can't really find a good and recent performance comparison benchmark. If you do feel free to comment a link to it and I will try to update this post. But let's say theoretically that a $lookup is twice as slow as a SQL join. That would be a very large difference in a large scale project. I have had SQL projects that were around 7 to 10 tables in SQL but that could be reduced to 2 or 3 tables (collections) in MongoDB through the use of the array type. In that same schema, we sometimes had to join 5 different tables together and using MongoDB that could mostly be reduced to 0 joins ($lookup). So even if theoretically, MongoDB joins ($lookup) would be twice as slow it would have still been faster because you have to do a lot fewer joins in MongoDB compared to SQL.Also, a lot of people complain about MongoDB not supporting ACID. But MongoDB actually does support ACID through transactions.I am not an expert in any of this and I am not saying that everything I have mentioned above is correct, the opposite is true. I want to know why I am wrong please tell me and let's have a civil discussion! Sorry for being all over the place in my post. Also if I find some good comments I will try to add them to the post also if they are reasons against MongoDB (of course).

How would you guys implement rate limitng without using libraries?
I've implemented one before using Postgres but now that I think of it, Redis is probably a better option. This is how I did itWhen a request is made, create a record with the URL endpoint, IP address, email address (for routes that requires user log in), last request at timestamp with current time, count at 1, and release at timestamp, say 1 minute from current timestampWhen subsequent request is made, retrieve the record, check the last request at timestamp with the request (current) timestamp.If it's 1 second apart, increase the count and update the last request at timestamp.If it's not, reset the count back to 1 and update the last request at timestamp.If the count reaches say, 10, check the timestamp of subsequent requests with the release at timstamp.If it's before, throw error. If after, process request and reset count back to 1 and update last request at timestamp.Should I rate limit all URL endpoints?Should all URL endpoints have the same window between requests?And should all URL endpoints have the same number of requests before reaching its limit and locking out subsequent requests?If you guys do it differently or have done it differently, please share.

Coming from PHP. What are the differences I should know to get started faster?
While I'm front-end oriented and is rather comfortable with web javascript, the only server-side language I can use for real work is PHP. So my understanding of how server-side works is rather limited to how PHP works on the machine. Regarding Node, I've only looked into a few videos and documents yet, but the way Node works seems to be much different than what I knew of PHP (i.e. PHP requires http server alongside in order to work, is it a correct understanding that Node does both http server and page scripting?)What are the core differences in terms of programming approach, practices and paradigms I should keep in mind, if I want to make less mistakes or dumb decisions?

Mocking the Database in Unit Tests - WHY ?
Given that I'm fairly new to server side testing, I've read that you usually want to mock the db for unit tests, and my reaction is: why in the world would I ever want to do that ? Building a query for the db that actually works is a huge (if not the MAIN) part of the server side (especially in node, since it's not calculation heavy), and I make use of it in pretty much 95% of the requests probably.So why ? That would make tests pointless as they would just be testing that my mock responds well to queries (which doesn't make sense). What am I missing ?

How to unit test private object variables mocha chai for typescript project?
After researching this I found the best response would be to test the private variables of an object against the prototype of the object. Effectively then inside the test creating a prototype and accessing the variables in that way. When I do this, however, it seems that all variables are not null but are undefined. How am I able to test the private variables, so that they remain defined? For reference, this is what I'm doing now:https://stackoverflow.com/questions/63162403/how-to-unit-test-private-variables-mocha-chai-for-typescript-project

Best way to sync dbs
I have a Magento db and postgres db for the app I am running. I want to sync data changes occuring in my Magento db for a particular table to be migarted to my postgres db each day.Wat I want to do is run a cron job every day and update postgres with latest increments changes.For that I want to use a AWS lambda to trigger a node js script which will use typeorm to connect to two dbs .it fetches from magento db in a single go and opens the postgres connection and writes to it.How should I modify this to be production quality? Is there a way to do it in batches or make it more reliable or fault tolerant or any good node js handling practices?PS: I dnt wanna use any queueus or messaging system

Integration through APIs
Beginner question here:I have 2 systems that I'm trying to integrate. I'll spare the details for now, but essentially I need to pull a quote from an accounting system into a CRM system. Both systems have quite an extensive API setup, so completely accessible from that perspective. I've used both APIs in the past, for other projects.My question is this:How do I get this to happen automatically? i.e the quote from the accounting system will be pulled into the CRM system automatically. I obviously do not have access to the code of either system as they are both big SaaS products. Just APIs...The idea is obviously to reduce the amount of work that a human being physically has to do, which is why I'm trying to automate as much as possible.My apologies if this is a dumb question, or if there is a simple fix - I've never been in this position before!

How do I mock an Azure SQL database using Jest?
Hi All,I am looking to mock an Azure SQL database for Unit testing purposes. My database does not have, nor will have, any triggers or procedures. Its all just simple select and join statements based on CRUD requests from my express endpoint. Is it possible for me to create a fake database file containing my schema and dummy data and intercept any requests from HTTP requests?Example code I want to test inside a Users route (ie. http://localhost:3000/users )router.post('/', async (req, res) => { ...validator... try { const pool = await dbConnPoolPromise const result = await pool.request() .input('name', sql.NVarChar, validator.escape(req.body.name)) .input('role', sql.NVarChar, validator.escape(req.body.role)) .input('email', sql.NVarChar, validator.escape(req.body.email)) .query(SQL_INSERT); res.status(201); res.json(result.recordset[0]); } catch (err) { res.status(500); res.send("ERROR, Users Post" + err.message); } }); I would like to have a file that intercepts this POST request and immediately Promise resolve to, say:{recordset[{name:"Foo",role:"Bar",email:"foo@bar.com"}which shows the data that I have inserted.I can then do an assert based on this using Supertest. I have previously used Jest to mock functionality on the front end using the spyOn function so I imagine I can do something similar here but cannot find a lot of information on it. Has anyone done this before? Thanks!

Best practices to limit timeouts when working with Slack API
Hi folks - I'm experiencing a ton of timeouts when working with the Slack API on my node server (currently I'm using serverless Google Cloud Functions). I'm wondering if there are any best practices I'm not using that are causing this slow downThe Slack API has a 3 second threshold before it assumes timeout or expires certain tokens. My functions aren't running that quickly. Specifically in my case, when a user uses a slack slash command, I want to send back a modal for them to fill out. However, the trigger_id that I need to send back with the modal is expiring before I can send itAny tips for a new user of both serverless and the Slack API?

Discord.JS Unknown Command Duplication Glitch
Hello,I am currently working on some code for my Discord Bot, and was wondering if anyone could help. Right now, if I do an unknown command, the right thing will pop up, but when I do a valid command, it will show the unknown command prompt, and the valid command's prompt. My guess is I have code that I would like to use, but right now, it is space insensitive, meaning it will not react with spaces. If the command is one word, it will work perfectly fine, but if the command is two words, it will not react, and will make a duplication glitch. Below is my code.client.on("message", message => { if(!message.content.startsWith(PREFIX)) return; const unknowncommand = new Discord.MessageEmbed() .setColor('GREEN') .setTitle('SCOTT') .setDescription('You\'ve entered an unknown command. \nUse **!help** to see all available commands.') let validCommands = ["eat cookies", "eat ice cream", "eat choice", "eat candy", "eat lollipops", "eat fudge", "eat donuts", "eat gum"]; const args = message.content.split(" "); const command = args.shift(); const isValid = validCommands.includes(command); if(!isValid){ if(message.author.bot) return; return message.channel.send(unknowncommand), console.log(`[SCOTT] ${message.author.username} entered an unknown command in "${message.guild.name}".`); } }); I do not know if this is the right place to ask, because in Stack Overflow, the community was very rude and unhelpful, so I hope to get better responses here, and for someone to tell me what I am doing wrong!

Thinking of switching to Node for all my current and future projects?
Hello r/node! I have a couple questions about NodeJS. I'm sorry if they might sound stupid but I've never touched front end web for a long time as I'm mainly an iOS and Python dev.I'm having trouble as an indie developer/entrepreneur maintaining knowledge in a couple programming languages, so I was thinking of moving over to JavaScript to I can crush the Front End and Back End with just one programming language. I'm currently using Python Django for my server.It's just very hard maintaining knowledge in the Front End (JavaScript) for my website, also iOS (Swift) & Python (Backend). I hope you see my worries here.Anyway I wanted to ask if Node JS was production ready? Can I make banking applications with Node and maybe some blockchain projects in the future? Is machine learning viable with node and javascript? I just want to make sure I can use JavaScript and Node JS for all my future projects so I don't have to hop around all these frameworks and tools like I do now.Thank you in advanced for anyone who takes the time to answer these questions!

How to find all occurrences in an array in a field in mongoose and nodejs?
I am working on a project where I have a chat between users. In my chat schema, I record the users who are a part of that chat.I want to add a profile for all of my users, however, the only thing inside of the profile is which chats they are a part of. Basically, what I want to do is when a user visits their profile page, I run through all of the chats to and see which chats contain that user. I then return JSON containing which chats they are in. I'm having difficulty with this however, particularly with how to go through all of the chats to find instances of the user. Currently, I'm doing this:const user = req.user.id; const chats = Chat.find(chat => chat.users.includes(user)); However, it is not working. What should I do instead. Additionally, below are my files for my Chat model, and my entire get profile method, to get the chats. Any help is appreciated!Chat Model:const mongoose = require('mongoose'); const Schema = mongoose.Schema; const ChatSchema = new Schema({ title: { type: String, required: true }, password: { type: String, required: true }, creator: { type: Schema.Types.ObjectId, ref: 'user' }, users: [ { user: { type: Schema.Types.ObjectId, ref: 'user' } } ], code: { type: String, required: true }, posts: [ { text: { type: String, required: true }, title: { type: String, required: true }, date: { type: Date, default: Date.now } } ], date: { type: Date, default: Date.now } }); module.exports = Chat = mongoose.model('chat', ChatSchema); profile endpoint:router.get('/me', auth, async (req, res) => { try { const user = req.user.id; console.log(user); const chats = Chat.find(chat => chat.users.includes(user)); res.json(chats); } catch (err) { console.error(err.message); res.status(500).send('Server Error'); } });

Alternative to Prisma for Postgresql
Prisma + Postgresql is the go-to solution for my apps. I find Prisma to be better documented and more easily usable than TypeORM or MikroORM.However, I had a particular feature that I needed for an app that isn't available on Prisma. Currently, it isn't possible to increase the value of a certain field by a certain value using update. I mean, there is no way to do this:update table set field = field + 10 where (some condition) without resorting to raw SQL.Is there any alternative that is comparable to Prisma? I use code-first approach, ie. I declare the models in the code and migrate them to the DB instead of designing the schema using SQL.

Can you recommend me a maintained boilerplate of NodeJS, Express, MySQL, TypeScript, Docker?
It needs to have these:NodeJSExpressMySQLTypeScriptWith optional support for:Docker -- prod and development configs are fine, but I can set these up laterPGSQLiteIt also needs to have auth boilerplate with JWT -- `/ login`, `/register`, `/me`And if services are separated from the controllers, it'd be amazing. I tried a couple repos but there are issues I wasn't able to resolve, not sure how to go about it.

How do I add multiple schema types for a single field inside a model in mongoose?
I'm creating a project management app using React, Node and MongoDB.I have created a project model (using Mongoose) with the following properties:const projectSchema = new mongoose.Schema({name: String,tables: {type: [],default: taskSchema,},deadline: Date,dateOfCreation:{type:Date,default:Date.now}});By default the tables property will be of the taskSchema type which consists of following properties:const taskSchema = new mongoose.Schema({name:String,assignedTo: [String],status: {type:Number,default:0},dueDate: Date,filesAttached: [String]});As one can see inside the projectSchema, I have defined a property tables which by default is of taskSchema type.I want to provide the user to add another table of some other schemaType like schoolSchema, which has properties like: numberOfStudents, services, activities etc..How do I specify the tables property of the projectSchema to have an array of different schemaTypes?Because the tables property can consist of both schoolSchema and taskSchema.How can I add multiple properties to a single field?

Nestjs / Objection - do I need to abstract database query away from services?
HelloCurrently, I am using objectionjs with nestjs. ObjectionJs model is injected in services and I am doing database querying stuff from my there.The project itself is very simple now, so this approach works well for me, but I don't know If I will have issues after more functionality. This is my first project on the backend side, so I am trying to learn doing things the right way.Is there better way, to move information related logic into another layer? Like Repository or model itself?I can declare static & instance methods in Objectionjs model and move information getting logic there. (Like finding item by email, find related items from another tables, etc...)I can create an injectable repository (an idea borrowed from Typeform), which will extend the model and add querying stuff there.

How to build filter search using node/express?
HiI'm trying to build a filtered search in Node using express. Essentially a user selects criteria in a form, and I return results. I'm building this as a JSON API.I receive a url which contains various query params (eg http://localhost:7777/property/search?county=kildare&bedrooms=2),and this calls the following function exports.searchProperty = async (req, res) => { const query = { county: req.query.county || { $exists: true }, town: req.query.town || { $exists: true }, bedrooms: { $gte: parseInt(req.query.minbed) || 1, $lte: parseInt(req.query.maxbed) || 10, }, bathrooms: { $gte: parseInt(req.query.minbath) || 1, $lte: parseInt(req.query.maxbath) || 10, }, price: { $gte: parseInt(req.query.minprice) || 0, $lte: parseInt(req.query.maxprice) || 10000000, }, floorArea: { $gte: parseInt(req.query.minfloorarea) || 0, $lte: parseInt(req.query.maxfloorarea) || 10000, }, type: req.query.type || { $exists: true }, features: { $in: [req.query.features] } || { $exists: true }, }; const property = await Property.find(query); res.json({ items: property.length, property, }); }; Is there a better way to handle this. ie structure, handle fallbacks, and validation/security.

How'd you use the mssql buffer made from a varbinary containing a file in hex?
Hello, I having BIG issues sending file from my server to my client. Here's is what I'm doing:- on client side, I send the file object that multer download.- upon downloading on the server side, I read the file in HEX with fs and store the buffer as varbinary in my database using mssql, then delete the temporary file.That part above is working.Then when I make a get request to get the file and use it on my web app (webviewer, user icon, etc), mssql returns me a buffer for the varbinary column. This is where I'm lost. I don't know how to reconstruct the file from that buffer. Here's what I attempted:- sending the file in different format (binary, utf 8, hex,...) as string and trying to rewrite it on the client side in a new buffer, from which I would create a blob- sending the buffer containing the file with the content-type header set to its mime-type, then using a ReadableStream to write the file into a blobThe best I got was a corrupted file displaying gibberish and nonsense... I desperately need help, I have lost days on that and I'm making 0 progress... I've been searching again and again but it's like no one ever did what I'm trying to do, so I'm picking from solutions to other problems but it didn't work too well for me so far...

Need Help Parsing 90k JSON files
I have an assignment to create a simple site that parses a huge dateset of clinicals trials and returns the authors with most papers on a specific disease using a specific drug. Below is the code that I used:async function searchFilesInDirectoryAsync(dir, disease, drug) { const files = await fsReaddir(dir); console.time('test'); var i = 1 ; for (file of files) { console.log(i + '/89133'); i++; var fileContent = await fsReadFile(path.join(__dirname, dir, file)); fileContent = JSON.parse(fileContent); const texts = fileContent["body_text"]; const reducer = (accumulator, currentValue) => accumulator + currentValue['text']; const text = texts.reduce(reducer); const regexDisease = new RegExp('\\b' + disease + '\\b', 'i'); const regexDrug = new RegExp('\\b' + drug + '\\b', 'i'); if (regexDisease.test(text) && regexDrug.test(text)) { console.log('Found') } else { console.log('Not Found'); } } console.timeEnd('test'); } The problem is that the above code takes around 26 minutes for 89k files, the 89k files amount to around 1.5 gb of JSON files.The only way I can think of to increase performance here is to not use the reduce method to glue all the texts of a paper together but instead to run a regex on each text.The body text in the JSON files contains an array of many texts that all together make up the whole body text. One of the problems is that with the above code my PC caps my disk usage to 100% so it's bound there. Different ideas I had:- Run lots of processes in parallel- Find a way to regex for drug and disease in the same time though I found that it's not possible- Have node js call a executable from another programming language that has better performance- Maybe somehow to load the whole 1.5 gb dataset in memory for quicker readsI haven't tried any of the above mentioned ideas since I though I may get some good advice here on how to handle this problem.Any help is appreciated and thanks in advance for any answers.EDIT:Also below is a breakdown of how much time each step takes:read - 6.039msJSONParse - 0.387msreduce - 0.027msregex - 0.158mstest - 7.381ms

Cannot use import outside a module, even though the import is within a module?
I'm attempting to learn Node and JavaScript for probably the fifth time, and I'm stuck on what I assume is a pretty basic error. When trying to use import instead of require() I get the following errors:import { app, shell, BrowserWindow, Menu, ipcMain } from "electron"; ^^^^^^ SyntaxError: Cannot use import statement outside a module and a little farther down:(node:13732) Warning: require() of ES modules is not supported. require() of E:\Code\scheduler\main.js from E:\Code\scheduler\node_modules\electron\dist\resources\default_app.asar\main.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules. Instead rename E:\Code\scheduler\main.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from E:\Code\scheduler\package.json. The "explanation" it gives seems a little contradictory given that I am using import instead of require, and it says that it's an ES module yet above it tells me it isn't.After researching for a bit, I updated from v12 LTS to v14.6.0 which allows support for ES modules, and I added "type": "module" to my package.json in the root of the project. From my understanding this will make every .js file within the folder tree act as an ES module. However, I still get the same error and I have no idea why. Does it have something to do with Electron not supporting the use of import, or is it something else? If it is Electron, am I able to use require just for it but use import for everything else, or is it all or nothing?Here is the relevant code from my main.js:import { app, shell, BrowserWindow, Menu, ipcMain } from "electron"; import { MainWindow } from "./src/js/mainWindow.js"; function startApp() { const mainWindow = new MainWindow(); ... and from mainWindow.js:import {BrowserWindow, Menu, app, shell } from 'electron'; export class MainWindow { #browserWindow; constructor() { ... the rest of my code works fine, the import statements are my only problem.

Is node.js steadily declining?
It seems that event loop hype is fading away.I've been thinking of node and golang a lot lately and it seems that node is not that good for server.It does well as bff. But anyways it is more close to front than data. And at cpu intensive tasks, it is slow.On top of that, it seems that there is not that many jobs. Small to medium sized businesses may very well choose python, php with their mature and stable frameworks. As for node.js, it is not that good. Yes, there is express and nest but they are still not first class choice.I like js a lot. But after researching a bit, that's what I think of node.js.

Prevent attack using user creation in REST API
I've been planning out a project for quite some time now, and I am trying to figure out this one security flaw. I'm going to be using node and express for the front end and react native for the front end. The application is going to be on mobile devices only. Requests are going to be sent from the mobile device to the server to get data from the database.While I was thinking about the layout of the project I noticed one thing that could cause problems. I see no clear way to verify that requests to the user creation route are real traffic coming from the app other than having a pre-shared secret code that is sent along with the request, and even then the pre-shared secret could be extracted by decompiling the application. I think that there is potential for abuse of this via scripts with cURL to create large quantities of users. Is there any other way to combat this other than the aforementioned pre-shared secret?

But I haven't found any mention about a way to specify a file buffer for it.For example:- In C/C++, you can use setbuf or setvbuf function;- In C#, the FileStream class has certain constructors that allow you to set the buffer size, the class itself sets 4KB as the default buffer size.So is there any equivalent in NodeJS world or I have to make my own?Please note that I aware about Stream, but my need is the ability to seek backward and forward arbitrarily in a file (with the help of fs-ext package).

Where to keep access tokens when client is making API calls

Once I get the token however, I'm not sure where I should keep it to make additional calls to the API. This stackoverflow post (Link) suggests that I could keep it in localStorage since the client will be the one making the requests, but I feel like I've seen a lot of people suggest against storing things like the access token in easily accessible places like that.

Different ES6 “import” behavior between ESM Loader and Webpack?
Hi! I’m currently building a 3D multiplayer web game where my frontend consists of ES6 modules bundled with Webpack+babel. My backend uses vanilla node with the experimental ES6 module compatibility.One of my modules is used by both the client and the server, as they both need a copy of the game.This module uses three.js, but the problem is that when I try to include three using import * as THREE from “three”, THREE.Vector3 is apparently undefined on my node server while it works properly on the client.On the other hand, when I try to include three.js using import THREE from “three”, the opposite happens. THREE.Vector3 is defined on the server properly, but on the client it is undefined...Why does this discrepancy occur and how can I make it so that my module can be used on both the client and my node backend?

Which is easier to load balance? GraphQL subscription or socket.io?
I have a chat app (web and mobile) which uses socket.io to update the frontend data.I'm gonna need very soon to expend its resources by doing a load balancing and I see two options to do it but I don't know which one is easier to implement:Add Redis to the picture (The only reason I don't want Redis is because it is far too complex to install on my localhost (windows) which will make development (and future development) far too annoying... (because I'm gonna have to develop either on a Linux machine which I don't have, or on a development server which I can't really afford right now)Replace sockets.io with GraphQL's subscriptions, but I need to know if it's a solution which is easier to implement rather than using redis..I'd love to get help from people who had the change to load balance GraphQL and tell me how easy or hard it is to do it?Thank you in advance for any answer / advice :)

How do you share personal util modules between your projects?
How do you go about sharing a personal package (version controlled) between your projects? In my situation I’m using ts (src) and dist (js). I believe I can put it on github but not sure if it’s versioned or easy to pull down (nomenclature), also I’m guessing it is possible to publish to npm publically and give no fucks that no one will benefit from the package. What’s the move?Thanks!

Database Example
I am trying to find a good example of how a database should be handled in nodejs using mongodb.At the moment my DB calls are similar to this:function setCurrentDate(date){ return new Promise(function (resolve, reject) { try { MongoClient.connect(url, {useNewUrlParser: true}) .then((db) => { //Get the database let dbo = db.db('billboard'); let collection = dbo.collection('config'); collection.updateOne( { key: configKey}, {$set: { value: date }}, {upsert: true} ).then(() => { db.close().then(() => { resolve(true); }) }).catch((err) => { db.close().then(() => { reject(err); }); }); }); } catch (err) { reject(err); } }); } I am sure there are far better ways than calling the MongoClient.connect every single time and then adding all those closes manually. So I am looking to implement the DRY methodology but at the moment every single one of my DB methods starts with that MongoClient.connect and all of them have the db.close() littered through the call itself.I would greatly appreciate it if someone can point me in the right direction.

So far so good.I need to extract the json from here, and then output it to a specific path. In order to do that, I use node's zlib.Here is my script:const updateTranslations = async (url, path) => { try { const response = await fetch(url) pipeline( fs.createReadStream(response.url), zlib.createGzip(), fs.createWriteStream(path) ); } catch (error) { throw new Error(error.message); } }; The error is:Error: ENOENT: no such file or directory, open 'https://s3-eu-west-1.amazonaws.com/lokalise-assets/files/export/blablabla.zip'The url is here, and when. I copy/paste it in my browser, the file downloads correctly. But zlib can't parse it, so the script crashes. How to fix this? Should I use another library? If so, which one?Thanks!

Is using ES6 modules in a node backend bad practice?
Hi! I’m currently building a multiplayer web game where my frontend consists of ES6 modules bundled with Webpack. I plan to use node for the backend.I’m thinking that I‘m going to have the server reuse some of the modules that are used on the frontend. The problem, however, is that Node doesn’t support ES6 imports!First of all, is it bad practice to make the server reuse client-side code? I thought it would be nice if the app was “isomorphic” so that I don’t have to rewrite code for my server’s copy of the game. But something doesn’t quite feel right about what I’m doing.Second of all, is it uncomventional/bad to also use Webpack+babel to bundle my backend? (so that I can use ES6 imports in my server?)

15 Essential Node.js Packages To Improve Developer Productivity
Node.js is a pioneer in the asynchronous framework markets and used to create quick and scalable network applications. It supports a huge pool of startups and businesses that earn hundreds of millions of dollars in revenue. Node.js is the greatest disclosure of modern server engineering that we use and is not showing any sign of stopping. A new release of Node.js secures some loopholes in OpenSSL, and supports languages like C and C++Node.js packages helps you to use an event-driven, non-blocking I/O model. These important features makes it efficient, lightweight and totally adept for data-intensive real-time applications. It helps in achieving many purposes like back-end, front-end, APIs and robotics, improvement of development workflow and work model.You can also know reasons of why Node.js has become a standard for enterprise web apps at- Why has Node.js become a standard for enterprise web apps?Significance of NPM-NPM is a JavaScript node package manager. It is a default method to manage packages in Node.js runtime environment and supports use cases like publish, discover, install and develop node programs. By using NPM, javascript developers can easily share the code that they have compose to solve specific issues and other developers can reuse this code for their application.Three specific components-WebsiteCommand Line Interface (CLI) known as the NPM clientRegistry (it is the directory of information about packages)Registry includes more than 1 million Node.js Packages. These packages help developers to code by bringing simplicity to work. They can just install many NPM packages, copy few snippets and get ready with a decent demo for a JIT presentation.Top 15 Node.js Packages To Improve Productivity-1. Browserify-This package allows developers to develop organised, systematic and easy to navigate client-side codebase. With the use of Browserify, you can develop components that assign dependencies according to their use in different conditions. Generally, Node.js projects have many Node.js Packages, libraries and scripts. At such cases this package helps you to organize and give proper structure.JavaScript libraries are complicated to manage and you have to continuously check the templates to analyse which script is used by which libraries. As soon as you go deep into a project, script increases and hence it becomes difficult to tab on libraries and widgets. 2. Express-One of the fastest ways to get a programming language to serve your needs is through a framework. Most of the common programming languages have similar structures. It is a widely used framework to create and publish applications, and APIs rapidly. This framework has a minimal structure and by using Express generator, you can immediately launch a functional application. Also you can combine it with other Node JS packages for better performance.3. Socket.io-It allows developers to build real-time communication applications that need real-time streams of content , either from data in working or through an API from an external source. For instance, an apps like Twitter bot to collect latest tweets, a Facebook bot to watch news and combinations of APIs that work with real-time data. 4. Mocha-Testing is necessary for any project because it shows the application’s performance and the functioning of code. It is a Javascript framework that runs on browser and Node.js and also makes asynchronous testing easy. It runs sequentially with adaptable and accurate reporting. Also it maps uncaught exceptions to the test cases. From the performance report, developers can find specific errors and find a solution for issues.5. Bower-These days, websites include external libraries, tools, JS related utilities, frameworks and hence it becomes complicated to keep track of all these. And here comes the significance of Bower. It is a great package manager to control such situations. It can manages all components like CSS, JS, HTML, fonts and visual content works also. Bower allocates all packages that you’re using and helps you to be updated and consistently checked against potential risks. 6. Karma-Testing is an essential part of your project as it maintains the stability and performance of application. Karma is an efficient testing tool that allows you to test the code in browser and cross-browser too. It is used for testing during local development, every file save and server integration. It works seamlessly with terminal too.7. JSHint-It is a linting tool that reviews your Javascript program and identifies mistakes and potential errors. When your codebase is large, possibility of errors also increase and hence requires more time for debugging. With this tool, developers can effectively detect issues in code that can be a leaking variable, syntax error or implicit type conversion that cause bugs. In short, this tool improves your code and saves time for debugging. 8. Gulp-With this node.js package, one can strengthen and automate your application’s workflow and hence can increase your productivity in development workflow. It is easy to understand and implement and also offers a minimal API surface, major integrations that you can use with PHP, .NET, Node.js and Java.9. GraphicsMagick-ImageMagick and GraphicsMagick are the tools to manipulate visual content on the web. You can use both tools within your Node.js projects to optimize visual content. It’s documentation is easy to navigate and offers all tips and tricks, insights to use the GraphicsMagick library in a proper way.10. Restify-If you want to create a RESTful API, this library helps you with required tools to execute tasks. APIs are important in any node.js application as they make real-time more real. Restify is a helpful library for you while creating REST services for the web.11. Morgan-It is one of the most preferred library of Node developers. Morgan is a HTTP request logger that stores HTTP requests and give you appropriate insight into how your app is being used and where could be the potential errors might be that you haven’t explored.12. JOI-You can use this module for data validation process of your app. It could be easy scalar data types like strings and numbers or complicated values having multiple levels of objects and arrays. It is useful to build secure applications. 13. MongoDB Node.JS Driver-This library provides a necessary driver if you want to implement a full version of MongoDB within their Node.js projects. It provides a necessary space to use MongoDB to its node projects.14. Babel-Core-Babel-Core is a popular JavaScript transpiler having real name as 6to5. Initially it converts ES6 code to ES5 code but now it can convert ES6 to ES5, JSX to JavaScript, and Flow to JavaScript.15. Chalk-It is a very easy library that styles your terminal strings. Also the API of Chalk is simple and straightforward that works easily with all features of JavaScript that it offers natively.

I am new to node.js, very new. I have done 1 other website that basically only had a single line of text. Nothing complicated. The project I am currently working on is a touch more complicated. I have a NAS that I would like to use to source photos for what is basically a digital picture frame. Getting the photos themselves is not that difficult, what is difficult however is that I would like to update the photos on the client without having to refresh the page. And from what I can tell using websockets seems to be the best option. The issue there is I dont know how to use it at all. My goal is that every day it picks a new folder and every minute or two it takes a new image and push it to the client.The website design itself is super simple, just the image on a black background.Any suggestions would be greatly appriciated! I am also not opposed to changing from websockets or anything like that if it will be easier! It is also only going to be on the local network.Thanks!

How can i add a file browser to my web application?
I have device that is continually recording voice and stores it to a network drive. I was looking to be able to display this network drive with a nodejs web application. The files are stored in a .mp3 format and ideally id also like to be able to sort by date and play the files in the browser. How can I go about doing this

How do i add a delay until you can use the command again?
// Example: Fetching Balanceif (message.content.toUpperCase() === `${prefix}BAL`) {money.fetchBal(message.author.id).then((i) => { // money.fetchBal grabs the userID, finds it, and puts it into 'i'.message.channel.send(`**Waifu Tokens:** ${i.money}`);})}

Uploading GIFS to AMAZON S3, not working.
Hey devs!After several tutorials and questions found on SO, I came here for help. :PI have an API where I can send pictures to my bucket at S3. Everything is working fine, but when I upload a GIF, it doesn't work. The size is smaller than the original gif.I am using multer, aws-sdk, and multer-sharp-s3.Does anyone have any idea of what could be causing this? If I manually upload the same gif, it works!My code:const s3 = new aws.S3({ accessKeyId: process.env.AWS_ACCESS_KEY_ID, secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY, }); const multerFilter = (req, file, cb) => { if (file.mimetype.startsWith("image")) { cb(null, true); } else { cb(new Error("Not an image! Please upload only an image."), false); } }; const upload = multer({ fileFilter: multerFilter, storage: multerSharp({ Key: (req, file, cb) => { const userId = `${req.user[0].login}`; const todaysDate = `-${Date.now().toString()}.`; const extension = file.mimetype.split("/")[1]; const finalStr = userId.concat(todaysDate, extension); const fullPath = "projects/" + userId + "/" + finalStr; cb(null, fullPath); }, s3, Bucket: process.env.AWS_BUCKET_NAME, ACL: "public-read", resize: { width: 1135, height: 715, }, }), }); Reading the docs for multer-sharp, they have a toFormat param, and they say that you can set up as "gif", but when I try, I got this error on my server:throw is.invalidParameterError('format', `one of: ${[...formats.keys()].join(', ')}`, format); ^ Error: Expected one of: heic, heif, jpeg, jpg, png, raw, tiff, webp for format but received gif of type string Thank you all!
