Simple node plot library
Does anyone know of a quick and simple plotting library for node? I have an array of values I need to plot and don't want to go through all the overhead of plotly or any of the other large plotting libraries. Literally something that just outputs a quick PNG of the values in a simple line plot is perfect.

Looking for similar profiling tool like "php xhprof" in nodejs
We are running a legacy nodejs app which is using a lot of memory and I would like to start profiling the code so we can start reducing the memory footprint. Coming from php land we could use xhprof to create graphs which were super useful for finding the bottlenecks, but struggling to find what/how i would do that with node.Any suggestions would be helpful

Website speed: Is it better to choose Node or PHP for blog?
I used wordpress, noticed that expensive, "pro" and "optimized" themes weight 1-8mb and are ultra slow with tons of useless requests.Started creating myown Wordpress theme,i almost finished it.However i think i can go one step further and learn Node and create my own small backend+frontend for blog, but only if that gives me more speed.What you guys think about speed? Which choice will be better for me?

My work with nodejs on sails.js vs google cloud function with raw nodejs
Hey guys. I was working on heavy computation stuff in nodejs. It was like some matching algorithm with 3000 users. The aim was with 50k users. But currently we are using that algorithm on just 3000 users. The use case is such that it will create around 90000 rows in database . Now i have to apply my algorithm of matching users on those 90000 rows. Here is my benchmark:Nodejs with sails.js took around 4 to 5 minute. We have tried every possibility and now the end result id 5 mint. Earlier it was 40 to 50 minutes.Nodejs with google cloud function. It took 15 seconds.What the hell. How is this possible. Seriously i have no answers regarding this. And i am here for the answer.

I'm making a http server using nodejs. Here is a piece of the code:var mongo = new MongoClient(dbUrl);mongo.connect(function(err) {db = mongo.db('geeki')});I use db =, not let db =, so that the variable db can be used in all my functions. I have heard many advices that "don't use global variable in multiple thread nodejs". So my question is, if I use db this way, what problem maybe occur?

I am a node.js beginner and trying to setup a project but getting an error.Please Help.
I am trying to run a project name StageMate ( https://github.com/Langhalsdino/StageMate ) but getting an error while starting node.js server .When I run the command npm start I got an error " cannot find the path specified" .The content of package.json is as follows:{ "name": "StageMate", "version": "1.0.0", "description": "Intelligent presentation framework", "main": "index.js", "scripts": { "build-stage-mate": "cd stageMateApp; webpack", "start": "npm run build-stage-mate && node index.js" }, "author": "Timo, Enrico, Frederic, Jonas", "license": "MIT", "dependencies": { "angular": "^1.6.6", "angular-chart.js": "^1.1.1", "body-parser": "^1.18.2", "chart.js": "^2.7.0", "css-loader": "^0.28.7", "express": "^4.16.1", "mustache": "^2.3.0", "node-sass": "^4.5.3", "node-uuid": "^1.4.8", "raw-loader": "^0.5.1", "reveal.js": "^3.5.0", "sass-loader": "^6.0.6", "socket.io": "^2.0.3", "style-loader": "^0.19.0", "webpack": "^3.6.0", "ws": "^3.2.0" } This line ("build-stage-mate": "cd stageMateApp; webpack") is causing problem.And when i remove webpack and change the above line to ("build-stage-mate": "cd stageMateApp") The server gets started but shows a blank page on localhost.Steps I followed so far: 1. Cloned github project. 2. inside node.js directory --> npm installI also installed weback inside node.js directory. But when i tried to do same inside " stageMateApp " directory it shows error related to node-sass.Please guide what i am doing wrong ??

newb questions -- package.json -- older node version
There is a github source that I want to clone, https://github.com/MicroFocus/CX/blob/master/ig-overview, but the node version is 6 in the package.json file and my OS currently has 8 installed. The last updates for the project were put out about a year ago. So it is pretty fresh right? Yet node 11 is out.How likely is the code to work if I take every dependency in the package.json file and install each one but with the latest version that my node 8 can install via a npm command?node 11 looks to be out, I am running opensuse leap 15.0 fully patched which includes node 8. I also see the same with java versions, where they versions are just growing quickly with much shorter life cycles. How do we best manage dependencies for a given version and use later code as well? Are we restrained to having a container of one code base and another container for newer code base?

We, or every company, every project, and around the world often meet the same problems, and we are in general reinventing the wheels of other brothers. A significant waste of resources. What if we could build a community, and people could share their code, services, addons, or plugins that could be easily reused so that it could be plugged into the app. like my jigsaw puzzle? Hyron makes packing and reusing quickly much easier, it can help the product development process become much faster!https://i.redd.it/1g6rvwj7h5j21.pngBesides, managing the modules I see is also a problem to note.

Is using a module like concurrently to run processes in production a bad practice?
I am deploying a number of worker processes that will be doing backend processing work but not doing any sort of web serving or scaling. They are all super lightweight so I don't want to deploy each worker to its own instance and unfortunately I'm not super well versed with docker. The path forward to me looks like I could simply use something like concurrently to launch each worker process and then call it a day, but I'm not sure if that module is just meant to be used for local development. Thanks!

Authentication flow using custom authentication
TL;DR - Noob trying to learn about authentication without using a third party because I want to learn it first and not just jump into something I know nothing about and slap it in the application. What's the flow of authentication using JWTs and Refresh Tokens for log in, sign up, logout, without having to sign in every time like Discord.authenticate.js gistI'm really sorry for the long post... I know you're probably thinking "why are you trying to do your own authentication when you have third parties like Auth0?" Well I want to learn more about authentication and how it works before using a third party service. If I can do it on my own first, I will understand a lot more when I want to implement an authentication service for a real application.So I'm working on an authentication server for a chat application in Node that has the basics: log in, sign up, send verification code, confirm verification code, and logout. I got pretty much all of it working using JWTs, but then I thought that it would be nice to not make the user have to login every time a lot like Discord. So I looked into refresh tokens and wanted to implement that in my auth server. I think I have the flow down but like I said I'm learning this from very little knowledge. Everything has come from blogs, articles, and asking smarter people than I am such as you fine fellows.Anyway, I just wanted to get an idea on the flow of authentication. I got deep in the code last night and got so lost I'm pretty much starting over from the refresh token perspective. I want to do it right this time and make sure I have all the "gotchas" accounted for. So here is the flow that I think it should be:Login -> create JWT (expires in 15 mins) and Refresh Token (expires in 2 weeks) to send to the client both in the cookies (so it's sent with every request automagically) -> save the refresh token in the database -> go to secure route - let's say /profile - where a middleware called authenticate will be run to make sure the user has a valid, non-expired token -> if the token is expired but the user has a valid refresh token then create a new JWT, clear the cookies, add the new JWT and Refresh Token to cookies and send back to the client.Logout -> clear the cookies and remove the refresh token from the databaseWhat am I missing? I know I didn't go into great detail on the process I have but that's because this post is long enough, but the code is linked above if you want to check it out. I know it's ugly, but you understand now why I'm starting over.Thank you for reading if you made it this far, and I really appreciate your help.

node binaries take 500ms just to load?
I just spent a couple weeks scratching my head over a problem with a program totally unrelated to Node, which was caused by node which. Basically, node which was installed globally, so it was overriding /usr/bin/which. GNU which runs v. fast (3ms) compared to node which (500ms+).At first, I thought the problem was with node which itself, so I filed an issue on GitHub. Then, when debugging the issue, I realized that it takes over 500ms before the first line of the script is even evaluated:```javascript!/usr/bin/env nodeconsole.log((new Date().getTime()) - Number(process.env.START)) var which = require("../") ... ```sh $ START=$(($(date '+%s%N')/1000000)) which which 570 /usr/local/share/.config/yarn/global/node_modules/.bin/whichI'm on a 4th-gen Core i5 desktop Linux box and seeing the same behavior on a similarly specced laptop (ThinkPad T460). Is this just how node is, or is there some way to improve the initial load time?

Should my app have 1 DB file, or have queries spread throughout
Is it good practice to have 1 db file that contains all the queries that will be needed in my app, or have them spread out. Currently, I have 1 db file that creates the db connection with my MySQL database, and is called in every single one of my controller files. Each controller file then has a bunch of functions/queries needed for that controller. Which is better practice?

Beginner question regarding node and lambda, trying to connect to MSSQL
Hi, I'm currently new to node and I'm just trying to connect to an MSSQL database and putting the function on Lambda. However I'm very confused about this one particular concept. My current code is: sql.connect(config, function(err) { if (err) console.log(err); console.log("connected"); var request = new sql.Request(); request.query("SELECT * FROM COACHES;", function(err, recordset) { if (err) console.log(err); console.log(recordset); sql.close(); }); }); const response = { statusCode: 200, body: JSON.stringify({ message: "hello world" }) }; callback(null, response); I'm really confused on why this works, because I figured the callback would get called before the database retrieves the info, however it works. The following code that makes more sense to me, but does not work sql.connect(config, function(err) { if (err) console.log(err); console.log("connected"); var request = new sql.Request(); request.query("SELECT * FROM COACHES;", function(err, recordset) { if (err) console.log(err); console.log(recordset); sql.close(); const response = { statusCode: 200, body: JSON.stringify({ message: "hello world" }) }; callback(null, response); }); }); This makes more sense to me because the response gets sent back after the database has executed the query, however this gives me an internal server error and it does not connect to the database when I execute it in Lambda, any thoughts

[Question] How to fetch emails with their markup with Oauth2 (Gmail and Outlook)
Currently coding an app with Electron + React: The aim is to allow the user to fetch his latest emails from whatever service (in this case either Gmail or Outlook). These mails need to be fetched with their HTML markup and attachments. The user then decides if he wants to "archive" them, after which another unrelated process takes placeSo far I'm having a lot of trouble wrapping my head around Oauth2: What I've gathered so far is that using node-imap requires me to set the account to use "less secure apps" but from what I've read that is less than ideal. Not to mention it'd require the user to fiddle in their settings instead of just clicking "allow".Is there any "simple" way to set up Oauth2 in an Electron + React stack to fetch emails through node-imap? Tutorials I've found so far go to great tangents and always lose me somewhere along the way.As for fetching the emails themselves, node-imap allows to fetch plain text but not the HTML markup. After a thorough search through their issues the owner mentions and even shows an example, that sadly doesn't work.tl;drWhat is the simplest way to set up Oauth2 (on Gmail and Outlook) to be able to fetch emails and their attachmentsFollow-up question: In the case of Google, am I required to add credit card information per the recent changes in their API? I'm asking because this might pose legal problems in this specific case in my countryUsing node-imap (or a similar lib) how can I fetch emails as HTML markup, with their styles? (to be able to display them as they appear in the Inbox)PS: I also fiddled around with Mailkit, and I've managed to get emails with their HTML and styling. If I can't make node-imap work for me I'm considering using it thanks to Edge.jsBut that still leaves the Oauth2 issue.PSS: The HTML markup is not a hard constraint in this case, but would be greatly valued.Any and all thoughts are welcome.Thank you

Should I use Mongo for looking up permissions on every API call?
Hey everyone,My Node app has a security model that involves different users having different permissions. The users identify themselves by using JWT. On every call to a protected endpoint, my app:Checks the authentication token (using express-jwt)Checks the permissions they have (by extracting a user ID from the authentication token), to make sure they're authorized to access the specific piece of data they request. (This is what I'm working on, it's not implemented yet).Right now, the permissions are stored in Mongo. Is it efficient to call Mongo every time a user makes an API call? (The call would be made to a collection with a unique index).The other option I have in mind is to use something like Redis to cache the permissions, and to propagate every change to the data in Mongo to Redis as well.What do you think? Have any experience with something like this? The app currently runs on a 4GB machine with a Xeon CPU, but can be upgraded at will.At what load do you expect Mongo will feel the pain? Thanks.

Why koa is wrong?
Koa has been created for years but it will never be the next generation of express.Why?Mostly it is because of the wrongly designed middleware.Middleware we can know by name that it is a bridge between two entities.But koa's middleware is not. It is a container that wraps every so-called middlewares added later into the first one.so make the first so-called middleware most significant.The first middleware can modify every changes made by the middlewares inside it.That makes the middlewares inside the first one almost meaning less.It makes koa very vulnerable to middleware attacks and will destroy security models you build for your web sites.And also koa wastes a lot of efforts in rewriting express middlewares.In effect, to achieve promises and async/await syntax with express is very simple, even no need to write almost all middlewares for express.You can easily check it with vig:import { VHandler } from "vig";let app = require('express')();const handler = new VHandler();handler.set({prefix: '/demo',urls: ['/', '/hello'],routers: {get: async (req, res, scope) => {res.send('Hello world!');}}});handler.attach(app);app.listen(10000, function () {console.log('server running on http://localhost:10000');});

Using local storage to save JWT with React Redux?
Hello guys, actually i ended up a very basic authentication system using JWT, i'm saving it on my localStorage ( I'm using React & Redux ).Once a sign in the api returns me an object that contains User object and JWT i save these informations on my local storage even the user object, so every time the user open the website i check his JWT if it's available on the local storage or not, if yes i make him as logged in ( authenticated ) this works even offline, but i don't really like this one!I'm really confused about what i should do , i have to use the JWT because i'm working with the Strapi CMS!I really want to make this works like many websites, i mean when you close the web browser the user disconnect, but i'm not sure if this is good or not, even Facebook website is not working like that, because if you close your browser you still authenticated!Thank you guys! any suggestion will be appreciated.

PIRPLE - Stay Clear
So, apparently the owner Leslie Lewis doesn't know how to run a business. Normally, when users ask questions, they'll get answers, so long as they're within reason of course. However, that's not the case for Leslie. See attached photo from reddit user bishoymelek. In my own personal experience dealing with them, I witnessed their own support staff make statements that they had a hard time converting site visitors to customers. I then emailed them through their contact form stating I had some suggestions on how they could change some things to make their product more appealing to potential customers. Ignored for almost a week, I was tweeting to them on their Twitter channel about something else and made a statement that I was still awaiting a response for an email I had sent them about suggestions I had. I was told "You will continue to wait *insert 5 laughing emojis*". I replied that if they didn't want to listen to suggestions that customers had about how to improve their business, then it is their loss. Then they replied with something stupid about it being my loss or something like that, then more laughing emojis. I was then instantly banned from their platform.It's clear that they don't care about anything but bringing in money, and it's clear that they don't know how to run a business. Thinkific is the third platform (that I know of) that they are hosting their content on. Deep searches through Facebook, LinkedIn, Instagram, Google, and reverse image searches can't even find a Leslie Lewis that matches the profile found @ SkillShare. Clearly, for whatever reason, if Leslie is even his actual name, he wants to hide. Don't give them your money. Plus, their courses are outdated anyway, but they try to push the content off as brand new.https://www.skillshare.com/profile/Leslie-Lewis/7653916

Hey community!
Been learning node.js for the last few days, and digging how simple it is to get a server up and running. Im creating a few APIs first and then a few websites.Im coming from a ios swift and python automation background and I know I could have gone for Python for all of these, but node just seems like the obvious choice right now, based on the popularity etc.Ill soon be getting into some actual coding, the syntax has been pretty hard to swallow as I dont have any JS experience, but im definitively getting there.Just came to check out the reddit community! As I might be spending alot of time here these days (Hopefully not, as it usually would mean im having a extremely difficult problem lol!)

Good tutorials for caching in node?
I saw a bunch of them using redis but they require calls to redis before every mongo hit, I get that that's how it's supposed to be because one would first want to find if it's available in cache on GET and update cache on POST but still feel that a better way would be available.Memcache or redis, comment up a tutorial that helped you apply it to your project as someone who's never used any caching before.

Client side rendering of a chart using dc.js
I'm confused about how to render an interactive chart/graph on a client side.The current set up involves running express on a raspberry pie where the user would be able to see some sort of data when connected to the pie's connection. For the chart package, I have been leaning towards dc.js since it has all I need.But for actually rendering the content on the website, I need some guidance.

What should happen to my application if the connection to my hosted database fails to connect?
Currently I have the server throwing database connection errors to the console for development sakes, but what should happen to the application if there was a 'no connection' situation to the hosted database? For instance, right now my Express server will just throw an error in the console(to notify me), and then keep on moving if Mongoose happens to fail connecting to MLab.I figured this is alright because the routes that are requested by the client that read/write to the database already have error handling logic inside of them that would return any database errors back to the client to handle.Anyways, just something I couldn't really put into the right words for Google. Thanks for reading!

This is my first react app and I've been uploading my previous projects (which are just vanilla js, html, and css projects) to github using the github desktop app. I initially tried this but it did not work with this react application. I then googled how I upload react projects to github pages and have come across several ways to do it. I've tried them and they're not working. Can someone just hold my hand through this and clearly delineate my next steps like I did with the above 4? I've been stuck on this all day.

AWS Elastic Beanstalk deploy question
I'm hoping someone can help out before I've torn all of my hair out.I built a really basic set of endpoints in Node JS using Express. All is running perfectly from my local dev environment. Deployed to AWS on Elastic Beanstalk, and the service posts successful responses from Postman, and the GET endpoints return data just fine if I just put the URL in the browser. The problem is, AJAX requests from simple front-end code on a Shopify site not only time out, but the Node console logs I have set on the endpoints don't even register that the AJAX request arrived. Tested the front-end code with endpoints on a non-AWS service that I know works and they return correctly. My console logs register correctly when I hit the endpoints with Postman. Doublechecked URLs, etc.For CORS stuff I have:app.use(function(req, res, next) {res.header("Access-Control-Allow-Origin", "site");res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");next();});Is there some AWS setup thing I might be missing, maybe around inbound traffic, to have client-side AJAX requests be accepted as inbound traffic and respond successfully that I just don't know about?My inbound rules currently are port 80: 0.0.0.0/0And 443 same thing, but this install doesn't have an SSL certificate, so I'm not sure that matters. Outbound is wide open.AJAX request is just this in case I missed something AWS-centric that needs to be here?$.ajax({url: url,type: 'POST',async: true,crossDomain: true,contentType: 'application/json',data: JSON.stringify(data),success: function(res){console.log('response-received');console.log(res);},error: function(res){console.log('error');console.log(res);}});It's a Friday, so am I just missing something really simple here? I've been at this for tooo many hours. Any help greatly appreciated. Thanks!

How to Read graphql body from Request?
I may be going about this all wrong, but I'd like a middleware piece that can read the graphql request. If it is for login mutation only, I can let it through without a valid session, else require a valid session. I could keep a whitelist of queries and mutations that are allowed through.I can't figure out where in Request the graphql is actually being stored.I'm using express. Any advice?I'll update this as I figure out more.const config = require('../config/config.js') const fs = require('fs') const path = require('path') const express = require('express') const expressGraphql = require('express-graphql') const expressJwt = require('express-jwt') const {schema} = require('./schema') const {root} = require('./root') const app = express() // JWT, applies a user to the req if the jwt is valid, req.user app.use('/graphql', expressJwt({ secret: config.sessions.jwtsecret, credentialsRequired: false }), function(err, req, res, next) { console.log('123') if (err.name === 'UnauthorizedError') { res.status(401).send('invalid token') } // currently, authorization happens at the resolver level. // Resolvers check that the session is still in the session store // This allows functions like login to run without a token // But will automatically reject bad tokens } ) // Test Middleware var logger = function (req, res, next) { console.log('\n\n\nLOGGED') console.log(req.user) console.log(req) next() } app.use(logger) // ================== This is the part I'm trying to figure out =================== // I want to make a peice of middleware that inspects the graphql request. // if it is for login only, pass it through // anything else, get the jwt, req.user, verify that the session is active // If they have an active session pass it through // Apply graphql to the App app.use('/graphql', expressGraphql({ schema: schema, rootValue: root // graphiql: true //pretty much limited to login because you can't modify header to include jwt })) // Start the server const server = require('https').createServer({ key: fs.readFileSync(path.join(__dirname, '../cert/key.pem')), cert: fs.readFileSync(path.join(__dirname, '../cert/certificate.pem')) }, app) const port = process.env.port || config.app.port server.listen(port, function () { console.log('Server started.

I built this tool to solve my biggest frustration with the command line
Hey all, I have spent a few months coding an open source tool that has helped me tremendously with my day-to-day development and devops tasks involving the command line. My tool is called nama and can be found at https://github.com/alecdibble/nama. It allows you to store, organize, and easily run aliases . It incorporates tab autocomplete to make searching and running aliases really easy and fast. Right now, it only supports bash. nama is written mostly in node, with some bash scripting to provide part of the console-based functionality.I have a lot of freelance clients and need to remember many commands day-to-day, including SSH servers, dev environment scripts, database tunnels, handy backup scripts, and more. nama has helped me switch contexts and not have to stress about looking up common commands constantly. I have also built out a cloud service, called AliaSync, that is powered by the https://github.com/alecdibble/nama-sync package. I wanted a way to have my commands available on remote servers and keep them in sync on all of my computers, so I created AliaSync to provide that. It doesn't yet have a website or any web present besides the nama-sync github & npm pages.I am posting to get general feedback about the idea and am hoping that someone is willing to try it out and report bugs or give more detailed feedback. Thank you!

Testing OAuth2-protected API endpoints, it is even possible?
It seems that a lot of people worship test-driven development and I think it super helpful if you develop API endpoints. But I am just wondering how to deal with OAuth2-protected endpoints (e.g. protected with LinkedIn-OAuth2).Mocking the OAuth2 provider would need to mock/rewrite the entire server app, isolated unit tests without login state don't seem to be really helpful. Setting up browser tests with puppeteer simulating all the clicks through the site just to test some protected API endpoints feels like taking a sledgehammer to crack a nut (paired with the problem that's is not so easy to create test accounts on LinkedIn without getting flagged).So, do I miss something? How do people deal with this? Is this entire thing about TDD/BDD just empty talk and only basic stuff is being tested (like the server responds status 200)?FYI, to get the auth code from the OAuth2 provider (e.g. LinkedIn) the user needs to go through the login flow. So, I don't see any way how to just provide a given code while skipping the login.

This would allow pages to load dynamic content from the sql database before the page rendered. For example, showing a profile page with user information.Is there any way to do this in NodeJS?

[ Express JS] Maintaining middlewares with side-effects
Hey! I've been working with express.js for the past two years now, and one thing that I found to be quite difficult is how to properly document and enforce the state of the req object when multiple middlewares are mutating it. For example, I might have a validation middleware that updates the req.body object so that it only contains valid inputs. Another middleware might fetch an account from the database based on the id in req.body.id, and place it inside of req.body.account.When chaining these middlewares together, there is nothing that is preventing me from improperly chaining the middlewares together, with the exception of diligent coding.Has this been an issue for you all? If so, how do you manage this?A toy example is here: https://gist.github.com/pierreTklein/feca0766e4433ebb880a4558ac2a0706

How to send data bidirectionally between an infinite running Python process and express/Nodejs
I have an node.js express app that is handling requests on the frontend dashboard for users. I need to do some computations on Python and run some tasks using Celery. After some research I found the following methods. I am feeling overwhelmed with the number of possibilities here. Would appreciate some direction...Child Process (spawns and dies when the task is over I guess)Python shell (same as above)ZeroMQ or any other similar queuing systemI could have Python store the computed values to redis and access them from express route handlerI could have Python use a tornado web server to directly serve the computed content on a different route (express has lusca not sure what Tornado offers here for CSRF, also not sure if Tornado can play nicely with Celery, the TCELERY library seems seriously outdated)I could have Flask run a separate webserver with Threads to do IO and processes to do computations and serve results directly. (Lusca XRSF no idea, though it seems Celery is good to go with this approach)I could setup a pubsub channel on redis between normal python script that runs infinitely in DAEMON mode and the express serverPhew! so many choices, I am feeling paralyzedWhat would be a decent way to do this. Can anyone share their experience on this, thanks in advance

Where to store JWT?
I've been doing a lot of research on this and I can't really find a good solution to this. I think it really depends on what you want for your application, but that doesn't really help me. I'm making a small chat application using Electron and Node.js and I'm working on the authenication flow right now. I'm implementing passport.js (if you have a better suggestion please let me know, I'm open to anything) and from the research I've done you can store it in a lot of places but it seems that people say never store it in localStorage due to XSS attacks. Storing the JWT in cookies is good because you have the option to add the secure and httpOnly option to it which prevents such attacks. I thought that storing in the Authorization header was best because isn't that what it's there for??Anyway, can someone lead me in the right direction?

Learning about dev habits
Hey guys,Sorry to post a bit off-topic, and apologies in advance if you've seen my thread in another reddit. I'm just trying to get the best answers I can.I'm starting a new job at a tech company, which revolves around Developer Marketing. Although I've loved tech and programming since I was a kid, I never really had the technical ability to do it myself. Personally, I call it fascinatingly boring. I'm always so excited to try and learn a new language, but usually, within a couple of lessons I start feeling overwhelmed and with the "uneventfulness" of web tutorials, I hit a wall (and fall asleep). All this to say although I respect developers, I'm unable to feel your pain first hand.But enough about me. The reason I'm writing all this is because I wanted to do some homework and be prepared as much as I can. I was hoping some of you may be so kind as to spend some time answering all or some questions I have for you (they're only "10"), in hopes of doing a good job. I thank you all in advance for getting this far and for your help from here on out.Onto the questions:What are your main destinations for coding related themes? (Websites, Blogs, Q&A sites, etc.)What are the communities you rely upon to communicate with others? (reddits, BBS, etc.)Are there any personalities you follow or look to for info, advice or tips? 3a. What did they do to catch your attention? 3b. What do they keep doing for you to keep going back?Do you use any social media accounts for personal use? 4a. If so, which ones? 4b. How do you use them? Only for consumption or do you actively participate?Do you allow yourself to be tracked online? (Advertising IDs)5a. If so, only on work computers, or also on your personal ones?Regarding the major cloud service providers (Google Cloud, MS Azure, AWS):When looking for a service to use, what are your priorities when doing research? (Pricing, Features, Granularity, Security etc.)Is there any particular service you prefer using often? Is it a nobrainer? 7a. What does that service offer to make you choose them over the others?Is there anything missing in all these services that you would like added?Regarding Marketing, developers are notoriously a very hard audience, because you guys do so much research and are so logical and impartial, usual approaches don't work with you guys. So here is my final question(s):If you were working in Marketing, how would you target yourself?What do you think would be the most effective way to communicate a message to you?

First published article about Node.
I have just written my first ever article about programming, and it has been published by Smashing Magazine.It it about ES6+ JS, Node, APIs, HTTP, JSON, and more. It is the first part in a series which will eventually cover building an API with Express and performing server side templating.If you have time, I'd be interested to hear what your thoughts are for improvement.Link:https://www.smashingmagazine.com/2019/02/node-api-http-es6-javascript/Thank you.

HEDON header file
hey everyone,i created a simple( ,but messy (for now) ) header file.the whole idea was to create a tool that can bind functionality one-to-one, function to javascript function, array to javascript array,with the bare minimum integration code as possible when you bind a c or a cpp code with js code .i am wondering if anybody can find it useful, and if i need to it alive.unlike "nan" (which i like), i really don't want anybody to learn any macros or complex engine stuff.i know it's far from perfect and i would really like some feedback bad and worse.there isn't much,but the end to end test are in the bin test files and the test files.the git repo is : https://github.com/butterfly0x0/HEDONthe npm page: https://www.npmjs.com/package/hedonhthanks!

Question about interpreter location in shebang
Currently building a CLI and I have a question about the shebang line at the top -what does env node mean in /usr/bin/env node and how is it any different from /usr/local/bin/node?I know the point of the shebang is to point the file (once made into an executable) to the interpreter to be used.When I use the which node command on terminal, I get /usr/local/bin/node so shouldn't I be using THAT path in my shebang? Also what does env really mean - the space between env and node in /usr/bin/env node made me think env is a directory which is clearly isn't. Any help would be much appreciated - nothing in my code is broken (for now) but I'm just curious as to how this works under the hood.

Forwarding Request
I would like to create a service that allows only a list of IPs to connect to my server and they will send requests to a site that I will forward through a list of proxies and they can use a certain amount of traffic like 2GB, etc. The proxies they get will also have to be unique to them and rotates from the list every few minutes. How would I go about making this?

A method to access express session variables in the front end
I have been using express session variables for a small project, however, I have only been able to get express session variables into the page using templating. I would like javascript on the frontend to be able to access this data and serve the user dynamically. I have looked through document.cookie, sessionStorage and localStorage thinking I would find something(which I didn't) since I am new to handling sessions and cookies.One of the ways I thought of a way around this, is to have a route which would provide the user with the session details, let us say /api/getsession or something among those lines with fairly simple backend route code:Installed and used packages:ExpressExpress SessionBody-parser...A few others not required for this threadapp.get("/api/getsession",(req,res)=>{ res.json(req.session) }) However, since this would require the page on the front end to perform an http request, it might add onto the loading time of the page. Thus, if there is a way to access the session variables on the page itself, IMO it would be more efficient.Therefore if there is something wrong in the technique I am using or a better technique/package I could use, kindly point this out as I am new to node. Appreciate the help :)

How to Check Whether a Listening Port Accepts HTTP request?
I have a process running on port 5000 on a Linux server. How can I determine whether the process/ port accepts HTTP request? I tried using curl on a remote machine to check if the server accepts HTTP, but it doesn't return any response. If it doesn't accept HTTP request, is there a way to know what other protocol the process/ port will accept? Thanks a lot!

Why are node binaries not 0s and 1s?
I was sort of expecting my files inside node_modules/.bin to be composed of 0s and 1s. I guess I assumed that all "binary" files were this way, but I guess that's not the case? Is ".bin" somewhat of a misnomer then?

Open sourcing our visual coding node framework!
everyone, I thought here would be the best forum to share an open source bot framework that we developed for the last 3 years, hope you like it :) It runs on NodeJS, and comes with a visual behavior tree editor that allows super cool visual programming. It is built for chat/voice bots but can serve very well any automation task out there. It includes automated testing, sub processes, a debugger and much more. It's easily extendible -- extend one of 4 base classes, implement 1or 2 methods and you are done. If all this raise your curiousity then you are in for a treat: check out https://github.com/servo-ai/servo-platform

Linkedin Scraper / Crawler working 2019 for Node.js!
Since LinkedIn changed his website to a SPA-ish in 2018 (?) almost all scrapers stopped working, but seems that no one cared about it! I suppose due to Linkedin API. I also tried to use the API however it has a lot of limitations, the API only give us basic information, unle$$ you are a partner, so I built one for myself, and it seems that is the 1st which works on Node.js: https://github.com/linkedtales/scrapedinIt took over 2 months, more than 10k profiles tested, it reads full data and I'm very happy if it also helps other people 😊. The "trick" what made it possible was using "puppeteer" a chromium headless browser. It is really not very performant if you scrap only one profile at once (~1 profile per second) , but it works amazingly in parallel (~5 profiles 1.5 seconds), I also built a crawler using scrapedin in parallel: https://github.com/linkedtales/scrapedin-linkedin-crawler

After using passport.authenticate(), my express server routes all stop responding
I'm creating a small demo app to learn user authentication with passport.js, sequelize & express. When I hit my /register endpoint, it creates a user account just fine. Same with if I hit my /logIn endpoint, it'll return the proper user if I give it the correct credentials.The issue I've run into is that after starting the server up and hitting either the /register or /logIns endpoint the server will stop responding to all GET and POST requests until I restart the server.Here is my index.js code:var express = require('express') var bodyParser = require('body-parser') var Sequelize = require('sequelize') var session = require('express-session') var passport = require('passport') var bCrypt = require('bcrypt') var LocalStrategy = require('passport-local').Strategy var flash = require('connect-flash') var morgan = require('morgan') var app = express() app.use(express.static('public')) app.use(bodyParser.json()) app.use(session({ secret: 'keyboard cat' })) app.use(passport.initialize()) app.use(passport.session()) app.use(flash()) // Sequelize & Sequelize models var sequelize = new Sequelize('auth_demo', 'auth_demo', 'auth_demo', { host: 'localhost', dialect: 'mysql' }) var User = sequelize.define('user', { id: { type: Sequelize.INTEGER, autoIncrement: true, primaryKey: true }, username: { type: Sequelize.STRING }, password: { type: Sequelize.STRING } }) // Server initialization stuff require('./config/passport.js')(passport, User) sequelize .sync() .then(() => { console.log('Connection successfully established') }) .catch(err => { console.log('Unabled to connect:', err) }) app.listen(3000, () => { console.log('App is running on port 3000') }) // Routes. app.post('/register', passport.authenticate('local-signup'), function(req, res) { res.send(req.user) }) app.post('/logIn', function(req, res, next) { passport.authenticate('local-signin', function(err, user, info) { if (err) { console.log("found err") return next(err) } if (!user) { console.log("didnt find user") return res.redirect('/') } req.logIn(user, function(err) { console.log("executing login") if (err) { return next(err) } console.log(req) return res.send(user) }) })(req, res, next) }) app.get('/loggedInUser', function(req, res) { console.log(req.user) res.send(req.user) }) app.get('/test', (req, res) => { console.log(req) res.send('Hello') }) Also, here is the passport.js file to show the strategies:const LocalStrategy = require('passport-local').Strategy const bCrypt = require('bcrypt') module.exports = function(passport, User) { // Passport stuff passport.serializeUser(function(user, done) { done(null, user.id) }) passport.deserializeUser(function(user, done) { User.findById(user.id, function(err,user) { done(err, user) }) }) // Configure passport strategy passport.use('local-signup', new LocalStrategy({ usernameField: 'username', passwordField: 'password' }, function (username, password, done) { var generateHash = function(password) { return bCrypt.hashSync(password, bCrypt.genSaltSync(8), null) } User.findOne({ where: { username: username } }).then(function(user) { if (user) { return done(null, false, { message: 'That user already exists' }) } else { console.log("Creating user") var userPassword = generateHash(password) User.create({ username: username, password: userPassword }) .then(function(newUser) { if (!newUser) { return done(null, false) } if (newUser) { return done(null, newUser) } }) } }) } )) passport.use('local-signin', new LocalStrategy({ usernameField: 'username', passwordField: 'password', passReqToCallback: true }, function (req, username, password, done) { var isValidPassword = function(userpass, password) { return bCrypt.compareSync(password, userpass) } User.findOne({ where: { username: username } }).then(function(user) { if (!user) { console.log("didnt find user") return done(null, false, { message: 'User does not exist' }) } if (!isValidPassword(user.password, password)) { console.log("bad password") return done(null, false, { message: 'Incorrect password' }) } return done(null, user) }) .catch(function(err) { console.log("Error:", err) return done(null, false, { message: 'Something went wrong with your signin' }) }) } )) } If I hit that /test endpoint before I try to hit a /logIn endpoint or /register endpoint, it works fine and prints "hello" as expected. However, if I hit the /logIn or /register endpoint right after starting the server up and then try to hit /test the request will hang and not go anywhere at all.Here is what the express debugger prints in the terminal when it hangs: express:router dispatching GET /test +4s express:router query : /test +1ms express:router expressInit : /test +0ms express:router serveStatic : /test +0ms express:router jsonParser : /test +2ms express:router session : /test +0ms express:router initialize : /test +0ms express:router authenticate : /test +0ms It stops at express:router authenticate, so I'm inclined to believe it's passport.Any help is appreciated, thank you.
