What package makes it into every project you start, and why?
My go to packages are:dateFns: because it makes manipulating dates fairly simple, is of a modular design, so i only package what I use.clg-color: because it’s a super light weight way to add color to my terminal during development.What about you guys? What do you think new developers (and old) could benefit from including in their projects?

Node and websocket
I have a node server that accepts http requests. I am working on extending the functionality of server so it allows public clients to send continuous stream of data to my server. Websockets seems to be the obvious answer.Questions: 1. what's the best way to achieve my usecase (allow third parties to send high frequency, high load data streams to my server)? 2. i looked into socket.io.. will that force my third party clients to use socket.io on their end?Thanks

multiple express servers for subdomains or not?
Hi everyone,So I want to run a website on a server which will have a few subdomains too - all in node. With apache I would just setup some express servers to certain ports and have domains redirect to them - but with an apache-less setup, how would I do this?I could do it all under one express server, with `vhost` and `express-subdomain` packages maybe - but then if a dev updates one subdomain's backend code, I'd need to restart the entire node app to get it to update (I use pm2 for managing node.js stuff, is there a feature for hot reload without performance drop?) and so this isn't ideal.However, if I use a different express server for each subdomain I'd need to someone link them all with one master express server - and will running multiple express servers not affect performance?Thanks in advance for any help

Is there any coexistence between worker threads and the I/O thread pool threads?
Now with the latest node update we've got worker threads running in the same process as that of the main thread unlike clusters and child processes, so is that multithreaded/multiprogrammed or asynchronous?, if they are asynchronous how do they coexist with the existing thread pool used for I/O?, this might be a very naive question sorry for my ignorance,also, if they are asynchronous does this mean for cpu intensive jobs more cores should be made available to worker threads by decreasing the number of async I/O threads?

For example, "moment" is no longer found.Any ideas what the issue is or how I can solve it?Thanks ahead of time.

I've never used Node before so I'm completely new to this.I have this block of code with an async function.router.post('/new', async (req, res) => { console.log('Received Post Request: '); console.log(req.body.name); console.log(req.body.description); console.log(req.body.abv); try{ const client = await db.getClient(); console.log('Client Checked Out'); const { rows } = await db.query('INSERT INTO testbeer(name, description, abv) VALUES($1, $2, $3)', [req.body.name, req.body.description, req.body.abv]); await db.query('COMMIT'); console.log('Added entry'); } catch(e) { await db.query('ROLLBACK'); throw e; } finally { db.releaseClient( client ); console.log('Client Released'); } res.render('new', { title: 'Add New Entry' }); }) When I post a request from my browser, I get the following error at "db.releaseClient(client)"(node:14880) UnhandledPromiseRejectionWarning: ReferenceError: client is not defined However, when I add a second variable (i.e. "client2 = client", noted by **), it works fine.router.post('/new', async (req, res) => { console.log('Received Post Request: '); console.log(req.body.name); console.log(req.body.description); console.log(req.body.abv); try{ const client = await db.getClient(); **client2 = client;** console.log('Client Checked Out'); const { rows } = await db.query('INSERT INTO testbeer(name, description, abv) VALUES($1, $2, $3)', [req.body.name, req.body.description, req.body.abv]); await db.query('COMMIT'); console.log('Added entry'); } catch(e) { await db.query('ROLLBACK'); throw e; } finally { db.releaseClient( client2 ); console.log('Client Released'); } res.render('new', { title: 'Add New Entry' }); }) Does anyone know why this is?

How can one node instance tell all other node instances to do something?
I'm looking to implement a "Refresh Config" function where from my admin screen I can trigger my other node instances (on multiple servers) to re-load their config from the database. What's the best way to do this? I was thinking I'd store a flag in redis like reloadConfig = true/false. Then just have a middleware function check this flag and if true, reload the config from database.Anybody do anything similar to this?

Next.js CMS?
Hi everyone, I'm pretty new to using CMSs and I was wondering how they worked with react. If I was using Next.js to make a static site for a business, how could I let the business edit the content/information on the static site without having to change the react source files? I had a quick look at Strapi and I could use axios to make http requests to the API, and I could see how this would work for something like a blog that has blog posts, but I don't understand how it would work with just editing the content/information on a static site.

How to compress a large string with gzip to a file?
Hello, I was wondering what is the proper way to write data from in-memory to file and have it compressed along the way? The best I got is this. I get "Error: write after end" most of the time (not always).const stream = require('stream'); const zlib = require('zlib'); const gzip = zlib.createGzip({level: 9}); let Duplex = stream.Duplex; const stream = new Duplex(); stream.push(JSON.stringify(data)); stream.push(null); const inp = stream; const out = fs.createWriteStream('./foo.json.gz'); inp.pipe(gzip).pipe(out); I tried with a stream.passThrough as the input (it wants a readable) and got the same result.Thank you :)

circular dependencies in a react/react-native app
I'm planning on creating an app for web and native mobile using react and react-native. I've looked into how to go about code sharing between these two environments and have not found much useful info. I did come across react-native-web which tries to let you use your native code on the web too, but I'm not really interested in that, I want to write the native stuff using the react-native code and use standard web technologies for the web and I suspect trying to patch the react-native code onto the web would be a nightmare. So instead, I figure I should create 3 modules, one for strictly react-native, one for strictly react, and one for shared code. My only problem is I'm not sure how to deal with the dependencies. I figure the non-shared code should depend on the shared code since the non-shared code would be the entry point. However, I would like to also have component code in the shared code, but at a higher level. For example, if I created some low-level component in the non-shared code which implemented say a basic form (just as an example). Then I want to be able to refer to the correct lower level code at runtime so that on mobile it imports the native form and on the web it imports the web form. So basically I would like the non-shared code to provide dependencies for the shared code when it is imported. Is this possible to do? I haven't done a lot with nodejs modules before, so I'm not sure how to go about doing something like this and what technologies I might need. Thanks for any help.

Basically, its an app to spit out 5 random recipes per week with grocery lists.I'm working on the recipe endpoint as I'll allow a user to create a recipe to save that they will later cook when it comes up. In post, a user should create a brand new Recipe { name and instructions } and hasMany ingredients. An Ingredient has { quantity } and belongsTo an IngredientType which has { name, unit }.A user should be able to submit a recipe with ingredients(always created) and can either create a corresponding ingredient type or find one with the exact same combo of name/unit.My goal is to make this into 1 transaction so that if any validations fail, the whole transaction fails. Here is my current code:router.post("/", (req: Request, res: Response) => { const { name, instructions } = req.body.recipe; db.Recipe.create({ name, instructions }) .then(async recipe => { const ingredients: IngredientInstance[] = await req.body.recipe.ingredients.map((ingredient: any) => { const { quantity, ingredient_type } = ingredient; const { id, name, unit } = ingredient_type; db.Ingredient.create({ quantity }) .then(async ingredient => { const [ingredientType, ] = await db.IngredientType .findOrCreate({ where: { id, name: name.toLowerCase(), unit }}) await ingredient.setIngredientType(ingredientType.id); await ingredient.setRecipe(recipe.id); return ingredient }) }); return recipe; }) .then(recipe => res.status(201).json({ recipe })) }); This is obviously several transactions. The recipe is created, then every ingredient is created. I'm not sure how to make this one transaction though.

Debug flow through express Node.js application?
I've been looking for a way to better trace the code flow through an express application built on top of Node.js.I've tried the DEBUG environment variable but it's not quite what I am looking for.I am thinking more along the lines of which files were hit as part of the middleware flow, which routers were hit, which files were rendered including filenames/line numbers/function names.This would be very, very useful.Does anything like this exist?

What if I dont want to use loopback.js? What are my other options?
I am testing loopback and strapi.js to get some help while building api. Issue with loopback is , there are not tutorials on it. Couple of youtube videos and they are dead boring.Strapi is still in alpha.So, Is there any other option which can create api really fast. Like, in loopback, I can use cli to create some model,controllers.Should i do it in old way where i need to create end points and create all controllers manually?Thanks

Node express server integration with Cognito user pool

I'm heading towards #2 - roll my own - but want to know if I'm missing something easier / more robust.

What are your best resources for learning to build database structures.
I’m relatively new to coding and have only made your normal MongoDB based tutorial projects (yelpCamp and the likes).I want to sink my teeth into a rather daunting project of making a personal CRM/automating some of my day job. I know it’ll be a lot to take on but in my opinion being thrown in the deep end is the fastest way to learn. I also want to make it using an SQL based database system rather than Mongo as relational has more appeal to the types of data I want to work with.I can already visualize the potential for larger and larger amounts of data to be collected. I eventually want want tables for users, companies, employees, projects, financial history of different companies, status updates for different employees in individual projects, and also a logging system to see what user updated what record and when. I feel I can get the logic down relatively easily, but the most daunting task I see now is setting up the databases to be efficient and have minimal repeated entries.As I don’t have much experience in building out these larger applications, and to the best of my knowledge SQL databases aren’t the easiest to just alter and adjust on the fly, where is the best place to learn correct database structuring for my application?Happy to take any other advice on the project also.

Need Some Help With MEVN Stack Authentication
Good morning everyone,I've done a lot of work on this on my own. I've followed a tutorial on MEVN stack but it was coming up to be a failure. It may be because it's using Vue2? Not sure about that. Then I went back to my original, because I didn't think to check it before the tutorial. And it... works.What it is doing at the current moment is authenticating the user and then redirecting them to the express version of '/' and not back to the vue home. Is there a way with my current authentication will work with this. The files can be found at:The login route is found here:https://github.com/Randygbiv/portfolio/blob/api_and_frontend/routes/userRoutes.jsThe User model is found here:https://github.com/Randygbiv/portfolio/blob/api_and_frontend/models/user.jsWhat I'm asking is if the code I have here can work in any way to authenticate a MEVN app or will I have to completely re-write this. I really don't want to because it may change the way that the password is stored in the database and I've already got the working version in production.

I'm building a web app and I need some feedback on the way I decided to handle the backend structure.
I posted this question before in r/webdev and I didn't got a good answer so I'll post it again here.So I'm using reactjs and nextjs on the frontend and nodejs, mongodb on the backend. Now the thing is that I have two servers running for this application. The first one is the nextjs(well it's a nodejs server but you get the idea) which I only want to use to pass the request params on the front end, basically for just rendering the correct pages based on url and then use these params to call another server which handles everything else. To differentiate the servers I use /api/ for the second one.The second server interacts with the database but the database is on mongodb atlas(I do plan to move it to a separate server tho). Also I plan to use nginx load balancers so if one server goes down the app is still up and running. And just to make it clear I don't have separate machines as severs, the servers both run on the same machine with different ports.Also here is a scenario where, at least in my mind, makes sense to have a separate server for the ui. So the users loads a page and the first server sends the ui elements which needs to rendered. Now a request to the second server is made in order to get the data for the page. Let's say that the page has many comments and I just show 30 of them, if the user wants to see more he only needs to make a request to the /api/ server and leaves the ui server free for other users. So if I see the that the /api/ is under load very often and the ui one isn't I can just add another /api/ server to scale the app. Again I'm new to all of this so if this doesn't make sense please let me know.

But the problem is I can't understand a line of C++ ( native to leveldb ). Is there a native js key-value store DB that I can take apart and do some stuff on it?Have any of you did this?

Accessing An Object Across Multiple Modules
Hi guys. I’m sorry if this question has been answered already. Feel free to lay into me if it has.I working on my first big node app and I just feel like I’m doing this wrong. It’s an electron app for managing a football team, and one render process is designed to run during the game. While the game is being played, I have objects that represent each player, each coach, each referee, the stadium, the plays, the stats, etc. Then I have one object that represents the game itself. Sometimes, I need to access one object from another - for example, when I enter a play, it needs to reference player objects to update their stats, then access the game object to change the down and distance, etc.The way I have done it this: each Class is defined and exported in its own module. The exception is the game.js module - it defines the class, but the exports an instance of this class. Within that instance, there are objects that contain all of the other objects (players, coach’s, teams, etc) that I may need.When I launch the program, the game.js module is required and a new Game object is initialized. Then, within each of the other modules where I may need to access the game instance, I require the game.js module and assign a reference of the game object to a global (to the module) variable named ‘game’. Then, when one object needs to access another - say a Play object needs to access a Player object - i just use game.players[{plrId}] and it works the way I want it to.Is the best way to do this. I mean, it works, so why not? It just doesn’t feel right.Two things that make me question it. One, I use the modular-global ‘game’ variable within each instance of the other objects, which just feels odd. I could assign it to this.game, but that would create a circular structure, which I want to avoid.The second, bigger issue, is that I included the var {game}=require(‘./game’) one at the top of every module before the class definition, but I was finding that that didn’t always work. So I had to add a line in the constructor function that checked if game was undefined and if it was, then I would require the file again.TLDRHow do I make an object that can be accessed by multiple modules in a node project? Essentially a global object, though I don’t want to use that word.

Request not passing req.body through to other service
I have a Node.js API gateway that passes requests to my different services. It seems to pass the URL correctly (expected) but it is not passing `req.body` to my other services, in this case my auth service.Here is my routerouter.post('/signup', (req, res) => {request.post(req.path, options, (error, response, body) => {if (error) throw error;res.send(body);});});Here is my route in my auth servicerouter.post('/signup', (req, res) => {console.log(req.body);res.send(req.body)});I am getting back `{}` as my response to the API gateway so it seems like my `req.body` is not being passed through to my auth service. I'm not sure the correct way to have it pass through the whole `req` object to the auth service while using the request package.I think that I need to include `form: {key:'value'}},` somewhere in the request where I include `req.body` as part of the form data. Not sure how this would work since I already have the options included to set my base URL which is dynamic based off a setInterval elsewhere in my code.options = {baseUrl : serviceURL}

Node.js vs PHP?
In an interview a few days ago, I asked about their decision to use PHP for the backend rather than Node. I was caught off guard by his response of something along the lines of there being more packages/libraries available for PHP. However, I was under the impression that Node passed PHP in basically everything a long time ago. What are your thoughts on this?

What Javascript MVC web framework should I choose : AdonisJs, SailsJs or something else?
I need a MVC web framework to build my web application and I've run into these 2, (also Keystone but I removed it from the list since it doesn't have ACLs) . I've read some opinions on reddit about these 2 frameworks, but it's still not enough.So my question is what should I choose between AdonisJs and SailsJs (from the perfomance/documentation/maturity/etc point of view) ?

Dates on Nodejs on Windows 10 seems a bit off.
This might be the the wrong forum for this, but someone knowledgeable in this might be able to answer this quick and clean. Either it's my system (or rather two of my systems). If this is the wrong place to ask this query, then I'll apologize and head over to stackoverflow.It's regarding Date .Example: new Date(2019,1,1) 2019-01-31T23:00:00.000Z This does not seem right. Trying around with moment I'll get the following. ``` let date = moment().subtract(1, 'month');console.log(date.startOf('month').toString()); console.log(date.startOf('month').toISOString());Sat Dec 01 2018 00:00:00 GMT+0100 2018-11-30T23:00:00.000Z ``` Is this some mad quirk in JavaScript v8, since I have yet to see another language behave this way.

Question about the number of requests a simple node server can handle
Hi allI have two simple node apps (express) behind a load balancer. Between them they can handle about 400 requests per second. (Response time roughly 400 ms, and no lost data).I have a few questions on this please:How exactly can a single threaded app handle so many simultaneous connections? Is it simply a case of when a connection comes in, it quickly adds the request to the event queue, so actually it seems like it is concurrently handling all the requests but really it's just queuing them and processing them when it can?What would be the most effective way to improve the 400 requests per second/400 ms response time without scaling horizontally? For example, would doubling the RAM make a difference? Or adding a second processor? Or even removing express and using core node.js modules for the req/res processing? Or something else?Thank you for your responses.

How to lie to program about `process.platform`?
There is a CLI that runs on Node and can be executed via command on the command line. In its code, some functionality is deactivated for Windows users by if (process.platform === 'win32') { process.exit(1); }. Now I want to disable this check, and allow Windows users to use the "hidden" functionality (usually the the required software is not installed on Windows, but I have a special setup where it is).Is there some way, to lie to this CLI and simulate that it is running on e.g. Linux or macOS?Of course I could fork the CLI, remove the check and work with my own version - but this would require repeating this process for each release. As this functionality should also be available to other users, I would have to publish the forked and modified CLI which could be a frequent source of confusion for its users (What about version numbers? Do I use the same command?) - 99.9% of the code will stay untouched.Could I maybe write my own CLI, that does something to "fake" the environment, then executes the installed, original CLI, and cleans up afterwards?I created an example package that works identical to the CLI, but only does exactly that part that I am investigating:https://github.com/janpio/nodejs-cli-nowinhttps://www.npmjs.com/package/nodejs-cli-nowinInstall via npm i -g nodejs-cli-nowin.

Is something like Strapi worth using to speed things up?
I've been reading it's documentation, seems to be pretty fitting to use for CRUD development. Also has abilities to handle connection between models, handles data depending on that connection, etc. Anything further from that I'd be using my own functions, but that's where the tricky part starts. I'm not exactly sure if it's really smart to do in the long run. But the idea of having that CRUD functioallity alongside authentication, swagger documentation and basic subroutes seems very appealing.Are there any better options? Is using something like Strapi even a smart idea?

Electron questions for new node developer
I want to develop an application for work that will make workloads for everyone at the company a lot lot easier. I've decided that given my background in web development the best way to do this is with node and electron. I've done all my research and am confident this is the way to go and am well underway in learning all the ins and outs of node. I have a couple questions about electron though.Can I make my application with web pages now and then port it over to electron when done? Or will I severely regret not coding it with electron in mind from the beginning. Reason for this is I might make it a web app instead of a desktop app. Heavily leaning towards desktop app though given some company politics.The application I'm making makes heavy use of subversion (svn) commands. For windows users is it possible to include svn binaries (like sliksvn) with the electron package? Or is there no way around the need to instruct users to install something like sliksvn separately?

Creating a private local library of components dependant on react and styled-components
Hi folks,So I have a project the following folders at the project root: -- common- private-- package.json- public-- package.jsonprivate and public both represent self-contained applications. Both of the apps import standard js (ES6) functions and constants from the common directory via yarn workspaces in their respective package.json files: -"workspaces": ["../common"],As you can see, this goes up one level from the app root so are not under the npm packages in the package.json files and therefore are not compiled by webpack (don't need to be as they are standard ES6).This was fulfilling my needs until recently, when I realised my project would work better (DRY coding) if I were to move some react and styled-components dependant components common to both applications to the common directory. But, as mentioned above, they are not subject to compiling by webpack to I get an error when I tried to import them (doesn't recognise import styled from styled-components).What is the best way around this? Am I looking at having to compile that directory separately via their own webpack compiler config then import them from there or is there a simpler way to do it? Thanks.

Need your advice on node.js + express metrics monitoring
Hello everyone,I’m the CEO of a team of developers, we mostly develop web-based applications using ES + node.js + express + React. For every application we implement for our customers we have to be confident about maintaining our SLA-related metrics (we’ll simply lose customers if we aren’t able to meet our SLA terms) - which requires a proper metrics monitoring such as response time, error rates, etc.We had to invent a new small infrastructure each time we implement a new project, most often it was ES + Grafana/Kibana + modifications inside the app to collect metrics and ship them into the ES instance.So we got tired of doing the same thing over and over and created a cloud-hosted tool for our internal usage, which monitors all our node.js + express applications, we called it SLAO. It monitors all the methods calls with response codes, durations, headers, and other metrics, and we made its integration as simple as it could be - by adding a single row of code: app.use(slao()).Now we only use SLAO internally, but we’re considering publishing it as a cloud service because we think that we’re not the only team that had such node.js + express app monitoring issues.What do you think about this whole idea, should we go for it? P.S. If anyone wants to test it - just text me and I’ll give you a test access.

How to vssh into vagrant, run commands, and read the stdout?
I've been messing around with the 'child-process' module and trying to read the stdout. I've messed around with spawn and exec, but when I attempt to ssh into vagrant the output from vagrant doesn't return and it doesn't seem possible to execute additional commands within the context of vagrant. Not sure if this is making any sense at all... anyone familiar with running shell scripts from inside node with the intent to process whatever comes back via stdout?

Type of projects I should be working on to impress employers
Hey everyone. I recently began job hunting after being out of the game for the past four years. It's just time to move on. So NodeJS is much more prevalent than it was four years ago. I've begun playing around with some side projects to acclimate myself with it, but I don't think a chat application or a hacker news clone will cut it for an employer. I know I would catch on pretty quickly if I was in Node 9-5, but unfortunately I can only really devote 5-10 hours a week to learning it.What types of applications or skills should I be able to demonstrate to employers? I know thats vague, but again, this little chat application on my github probably won't cut it. So I want to think bigger.

Silly question, but regarding database connections...
Many examples seem to leave the password blank in the connection string, ie:module.exports = { 'connection':{ 'host':'localhost', 'user':'root', 'password':'' }, 'database':'bort', 'user_table':'users' } and when I've tried a few of these, I get connection errors. So... I'm guessing that the password for the DB connection is passed to that module when the server is running, however, I'm not sure how said password would be sent.what could I be missing?

Use node to write a variable from js to mongodb
So for a class project I'm creating a browser game in js. At the end of the game I would want to upload the scores to a mongodb database. (and later display it on another page). I've found that you can't write to mongodb with pure js so I'd have to use node.I haven't ever used node.js and tried just adding a function to my existing js file and running it with a json string from another function. However when I do that I get 'require is not defined'.So it seems I can't just add a 'require' function to my other js code and have it ran from inside that js file.To summarize what I'd like to do is take a json string that I have created in my js file upload it to mongodb atlas but out of my depth hereAny help would be awesome

Question: NodeJS secure file saving into file system. Preventing path traversal
Hello,I'm writing simple desktop app using electronJS(Please don't judge me using electron. I need fast solution for all 3 platforms)(electronjs runs on Nodejs engine), which let's user to upload files to cloud, list files, download files.When user clicks Download file, app downloads file to users selected destination in his computer. I want to prevent path traversal vulnerability, which would allow overwrite users local files when they download others people uploaded files.Use case: user selects download location "/home/userName/Downloads". Uploaded file have name "../.ssh/id_rsa". So complete save location would be "/home/userName/.ssh/id_rsa" and your privatekey would be destroyed.Possible solutions?:Filter file name and extension using blacklist and slice out characters like .. / \\ nullBytesIn web development blacklists normally never work, but in this case I need to allow all characters except malicious ones.var path = require('path');path.join('/home/userName/Downloads/', '../picture.jpg'); orpath.join('/home/userName/Downloads', '../picture.jpg');returns "/home/userName/picture.jpg", so path.join() doesn't helpThanks.

Even the bad stuff ;)Hi there,I just wanted to share one of my latests libs with you guys, also another sideproject whom was born from a project at work and we decided to separate it.It's a RPC Request/Response checker/generator wich tries to follow JSON-RPC 2.0 specification.It helps you with creating RPC Requests, Responses, Errors and Notifications with ease. It also checks they are valid.Also it has included a "cli comunicator", it sends and receives requests from stdin, but can be really easily changed!You can find it here: https://github.com/nombrekeff/json-rpiecyHere is an example:const rpiecy = require('rpiecy'); const request1 = rpiecy.createRequest('method', { /* params */ }, 'id'); const request2 = rpiecy.createRequest({ method: 'method', params: {}, id: 'id' }); request1.print(); request2.output(); const response1 = rpiecy.createResponse('id', { /* result */ }); const response2 = rpiecy.createResponse({ result: { }, id: 'id' }); response1.print(); response2.output(); // Parse will return a Request, a Response or a Notification depending on what was parsed! const parsed = rpiecy.parse('{"method": "method", "id": "id", "jsonrpc": "2.0"}'); request1.sendAndAwait() .then(response => { console.log(`Response for ${request.id}: `, response); }) rpiecy.listen((request) => { console.log(`Received request ${request.id}: `, request); request.response({ data: SOME_DATA }).output(); });

I made an API Rest generator with Yeoman.
About why made this generatorI'm pretty new at NodeJS, I started using it about one month or so, therefore, I'm creating a lot of disposable-projects.I made this generator because I'm pretty lazy, and every time I needed to create an Entity I thought to myself: It would be very helpful if NodeJS had something like JHipster's entity generator (I'm used to Java).So instead of searching for a NodeJS generator, I started studying how JHipster was made. A friend of my told me about Yeoman so I started studying about it, and the result is this two generators: lazy-backend and lazy-backend-entity.Main packagesI'm using Express, mongoose, and joi.LinksMain GeneratorThe main generator is the lazy-backend, is responsible for creating the project.Npm GitHubEntity GeneratorThe entity generator is responsible for creating the Entity (Entity = Routes, Controller, Model, and a Validator)Npm GitHub Plans for the futureAdd documentation/commentary for the generators and the generated project (If you guys could recommend a good and easy to document an API Rest I would be grateful. I've been searching about Swagger and APIDocs but I don't know which one to use)Add Front-end generator. (I've been studying React lately, so when I feel like I can do something reliability good I'll update the generator)If you find something that can be improved please tell me.If you want to contribute just send me a message.

Hello node redditers,My mobile app has implemented a search and filter method, it should filter products based on client criteria for exemple, brand, price etc..Suppose we have 1 million products, Is it better :- client fetchs all products from server then datas are filtered on client sideor- client sends http request for criterias (one or multiple) , then datas are filtered server side before sending back to client.I believe they all have pros and cons.First method :Pros : datas are feched once / Cons : Datas are too big and can take times.Second method :Pros : Only needed datas are fetch / Cons : A lot of request. Server does too much work in my opinion.Can anybody give me an insight ? What's the best way to deal with this without loosing on performance ?Thanks in advance for your help :)

Need help with express/HTML routing, completely stuck
I've been at this for hours, and cannot for the life of me figure out what I'm missing. No doubt it's a simple thing, but I cant seem to see it. I open my html page, and... nothing happens when i click the submit button. Again, it's a dumb question, but I'm stumped.I've checked as many stackexchange solutions as I can find, as well as several other sites. Nothing works, or so it seems.HTML (cant get simpler than this)

Connecting NodeJS Request Promise API to React.JS
Hey everyone,I apologize if this isn't the right subreddit but I thought this would be a good place to ask.Anyway, I'm currently trying to build an app using the coinmarketcap api. I have the basic skeleton up thus far, but I'm a little confused on how to fetch a NodeJS request-promise from the client side. I'm able to console.log the API, but I don't know how to pull this in with React.Attached below is a gist link to my server.js file along with my main App file.https://gist.github.com/camus-code/84c53662d29bf973e8ba2f167122727cThanks in advance!

When I have a simple nodejs script, setting the breakpoint on vscode prior to starting the script seems to work but in a sophisticated nodejs project with npm script - I have to debug by "attach by process ID". I don't understand what happens under the hood.

Confused on the order these are fired
I have an API that updates a user's profile and then gets the user's information again, send it back to the client.In my API, I haveawait client.query(`UPDATE user_profiles SET user_business_name = $1, user_address = $2, user_phone = $3, user_city_code = $4, user_country = $6, user_region = $7, user_city = $8 WHERE user_profile_id = $5`, [req.body.businessName, req.body.address, req.body.phone, req.body.code, req.session.user.user_id, req.body.country, req.body.region, req.body.city]); let user = await controller.session.retrieve(req.session.user.user_id); But it seems the controller is still getting the old user data before the above the query. This is my controller.jsconst db = require('../db'); module.exports = { session: { retrieve: async(id) => { let user = await db.query(`SELECT users.username, users.user_email, users.account_type, users.user_status, users.is_subscribed, users.plan_id, users.user_last_login, users.user_level, users.subscription_end_date, user_profiles.*, user_settings.*, user_listings.listing_status FROM users LEFT JOIN user_profiles ON user_profiles.user_profile_id = users.user_id LEFT JOIN user_settings ON user_settings.user_setting_id = users.user_id LEFT JOIN user_listings ON users.username = user_listings.listing_user WHERE users.user_id = $1`, [id]); if (user && user.rows.length === 1) { return user.rows[0]; } else { return false; } } } } When I change user's business name from BC #1 to BC's #1 and log it on my client side, I still see BC #1. Shouldn't the UPDATE fire first and then the controller selects the new updated data in controller?

Complex Question, Cant Really Summarize
Hey everyone, me again.This question is complicated not because of the code but rather the way I have to write the words. I'm almost positive that the code will be incredibly easy, but I cant find it.When I wrote my portfolio I stored my username and password on a database upon creation. Then I created a middleware folder with an index.js file. This file checks to see if I'm logged in. If I'm not logged in, it redirects to the login page or home page. This stack was (effectively) MEEN.My question is, is there a way to use that same middleware within vue by passing the session data back to vue?

Refactoring Controllers (Route Handlers)
Hi all,In the context of nodejs backend API applications, is it accurate to say that controllers(route handlers) have the following responsibilities (and nothing more):Extract the parameters (query or body) from the requestCall external functions to perform backend operationsReturn an HTTP response (with status code and serialized data)In the past, I have (admittedly with lack of foresight), done something of the following nature:function createUserController(req, res, next) { const userName = req.body.name // perform CRUD operations with an ORM User.create(userName) .then(function() { res.status(200).end(); }) .catch(function() { res.status(400).end(); }) } Aside from a bloated controller, I end up having express related objects passed down to data layers (as stipulated here: https://github.com/i0natan/nodebestpractices#-12-layer-your-components-keep-express-within-its-boundaries), which also makes it more difficult to unit test.To remedy this issue, what do you think of the following implementation:// Controller function createUserController(req, res, next) { const userName = req.body.name // perform CRUD operations with an ORM userDataOperations = new UserDataOperations(); userDataOperations .on('SUCCESS', function() { res.status(200).end() }) .on('ERROR', function() { res.status(400).end() }) userDataOperations.saveUser(userName); } // CRUD operations class UserDataOperations extends EventEmitter { saveUser(userName) { User.create(userName) .then(function() { this.emit('SUCCESS') }) .catch(function() { this.emit('ERROR') }) } } Have you guys experienced any issues with an EventEmitter implementation? How would you generally approach this?
