How do I write a buffer to a net TCP stream and send it to a server?

I'm still kind of finding my way around Node and net. Here is the code I have. I do add the port and host for testing.I got most of this code from an example in node docs: http://ift.tt/2AO26hk net = require('net'); const buf = Buffer.allocUnsafe(9); const client = net.createConnection({ [port,] [host] }, () => { buf.write('foo'); buf.writeUInt8(5, 3); buf.write('world'); console.log('connected to server!'); client.write(buf); }); client.on('data', (data) => { console.log('data is ' + data.toString()); client.end(); }); client.on('end', () => { console.log('disconnected from server'); }); Its saying 'connected to server!' but thats all im getting. I just know it wants a message starting with 'foo', the length of the rest of the message, and then 'world'.Anyone see any mistakes or able to offer advice?

Tips on creating a 1:1 chat/pm feature in web app

HiI'm creating a web app for my FYP, and I'm looking to implement a chat feature for users to chat. I want one user type to be able to message another user type. It also needs to be unique to these two users. Ie not every user can chat, just 2 users. I'm using Node and a mongo database. I've come across socket.io. Is that any use?Any tips/tutorial on how to achieve this?

Using socket.io to show a canvas circle on all browser windows

I'm very confused what to do right now, I got my server set up where a user joins and it draws a circle. Another user can join, it draws another circle somewhere else. But each user is not at the moment able to see the other.Client-side code: http://ift.tt/2AmrV52 my server, there is nothing 'connecting' to the client-side code. I think I need to emit something (like what?) to each side (server - client) to be able to see the players on both.What should I add to see other players?Thanks!

Some scope help.

I've inherited some node.js code and am still getting used to it. I'm having some trouble with variable scoping and have made a very small example to show where the problem lies.var RateLimiter = require('limiter').RateLimiter; var array = [0,1,2]; var limiter = new RateLimiter(1, 5000); for (var i = 0; i < array.length; i++) { console.log("i at for scope: " + i); limiter.removeTokens(1, function(){ console.log("i at removeTokens scope: " + i); }) } The output I get isi at for scope: 0 i at for scope: 1 i at for scope: 2 i at removeTokens scope: 3 i at removeTokens scope: 3 i at removeTokens scope: 3 So it seems i has finished incrementing before the log statements begin. I've been messing around with wrapping in functions and bind statements but I can't seem to solve it while keeping the use of the ratelimiter. Any help would be much appreciated.

confusion about functions exiting without return statement

I'm relatively new to nodejs and asynchronous programming in general. I have a section of code that is composed of a function that returns a promise followed by 2 functions connected by "then":function func_with_a_promise() { return new Promise (function (fulfill, reject){ fulfill(); }) } func_with_a_promise().then( function(){ console.log("There is no return statement in this function") } ).then( function(){ console.log("But we still arrive here...") } ) The output of this code is:There is no return statement in this function But we still arrive here... I would expect that the output is just "There is no return statement in this function", and the final function would never be reached because the second function doesn't return anything. But in fact both the final two functions are reached and output to the console.I must be misunderstanding something, please help!edit: ok after posting this I did a bit of digging around. It seems that javascript functions don't need a return statement. If you don't return anything, then javascript automatically returns "undefined". Is this correct?

Should I be looking for a memory leak?

I have a node web app hosted on a 1GB Linode VPS.Node (with express) is mostly used to serve json data. Some of the data is retrieved from another service through an API. The relevant part of the code checks if the data is stored in redis, if not then it makes an API call to the other service to retrieve them, processes the data a bit (nothing too intensive), saves them on redis and then responds.I also cache the responses with Nginx (which sits in front of Node) and with Cloudflare. The total number of requests for these data is about 120 per minute, but most of that is handled by Cloudflare and Nginx and only about 15 requests per minutes reach Node.Node can handle the 15 requests per minute if they are spaced out more or less evenly and the node process uses about 500MB on average. But if say 5-6 requests come at the same second then memory usage goes to about 850MB and PM2 restarts the process.Is that way too much memory use by the node process for so few requests? Should I be looking for memory leaks and/or inefficient code? Or is that within the limits of normal and I should just upgrade my VPS?This if my first node app so I have no point of reference.

Need help identifying best framework for my project's use case (mysql pub sub on various tables to stream data to front-end angular app)

Basically I'll be writing separate crons running on various servers that will push data to various tables in a mysql database on Amazon rds. I want to write a backend on nodejs that will stream these events (ie addition to data to various tables from my various cron jobs) to a front end angular app. My question being can something like socket io do that? or would it be better to refactor my crons to push data to redis and socket io pub subs to redis instead of mysql and redis periodically logs to mysql? I have done decent back end but never implemented anything like this- socket streaming with pub sub.I haven't started my project and maybe my architecture is wrong, I am open to any suggestions.

Using async package, how do I break out of "forEachSeries"?

Hi all,I'm using the async package in order to iterate over arrays of objects. I'm using a function called "forEachSeries". This might be the same thing as "eachSeries".If you're not familiar with this function, it simply iterates over an array with some code that has a callback function. It's basically a for look that operates over an array. The only problem is, I can't figure out how to break out of the loop if I need to.For example, if "forEachSeries" has only iterated over half the array and I have determined that I need to stop the execution of that function, I can't figure out how to break out of the loop. The only thing I can think of is to set a flag outside the loop, then encapsulate everything inside the loop with a check to see if the flag has been triggered. If I determine that I need to exit the loop, I'll just trigger the flag. Then each iteration will skip the code to execute and simply call the callback function. That seems horrifically inefficient, since I still need to iterate over the rest of the array even if I don't do anything.Is there a better way to do this?Here's an example of what I'm talking about. Let's say that I have an array of letters called "letters" that just contains some letters. I want to output each of them to the console, one by one. After I output my first letter 'c' I'd like to stop. So I've set up a flag called "continue_flag" that is true as long as I want the loop to continue. Once I run into the first 'c', I set the flag to false, but I still iterate through the array anyways without doing anything meaningful.I can't seem to get the code to format properly but it begins below:var async = require("async");var letters = ['a', 'b', 'c', 'd', 'e'];var continue_flag = true;async.forEachSeries(letters, function(letter, callback_function){ if (continue_flag){ //continue_flag is true console.log(letter) if (letter == 'c'){//check to see if the letter is 'c' continue_flag = false } callback_function(); } else {//continue_flag is false callback_function(); } } );Is there a better way to do something like this? Is async.forEachSeries even the best function to be using?Thanks!

Starting out with WebSockets - How to realize rooms?

I'm coding a website with a Node/Express backend and Vue frontend, and now I need Websockets and I don't have any experience with that. I've been googling the last two days and I almost made no progress, so many options!I've seen ws being recommended tons of times, especially more recently, while socket.io seems to be a bit bloated, and fallbacks are not needed as much anymore, with standard ws being more and more supported.I'd gladly go with WS, but sadly, it doesn't look like it has rooms/channels/broadcasts. Is there a way to recreate this? I've also seen socketcluster.io recommended, but that seems to be a pain to add in an existing project and slightly overkill already. Another question would be: If you use WS, do you use any WS modules on the frontend to make your life easier, or is the native WS good enough for sending stuff back and forth?tl;dr: websockets module for a noob with good docu and rooms/channels? Thanks!

What is the best way to implement validation in Node.JS?

I am getting used to Node.js, but I still have a hard time understanding how I should perform validation in Node.jsFor model validation, using an ORM I think is usually a good idea. For instance, Sequelize let you define the models and apply validation on the model's fields directly in the model definition.But if I have to validate other parameters, for instance, I want to validate a certain query parameter that tells how to respond to the client when it requests data, what is the best way to do it? What is the "state of the art" of nodejs validation? What do people use?It is really confusing looking to packages because there are so many that it is really hard to choose or understand which ones are worthy and which ones are not.

However I see that express is basically recommended everywhere. Is express to node like jquery is to javascript?I know I don't have to use it, I also rather not. But if it makes developing much more easier, and it doesn't make the app slower for the end-user then I'm all for it.

Express architecture for REST server

We are creating a REST server using Express, storage using MYSQL. There are two main components:1) REST endpoints that will be consumed by an app. These endpoints generally query the MYSQL db and return JSON.2) A 'synchronise' component that will retrieve data from an external web api and populate the MYSQL db.Question: Is it preferable to create the synchronise component as a separate node app running on its own process to ensure that the response performance of the REST server is not impacted by retrieving external data and writing to the db?

Question about CSRF and AJAX

I'm using csurf of a project with simply an app.use(csrf()) as middleware. I'm stuffing the CSRF token into my handlebars templates on the res.render('template', {csrfToken: req.csrfToken()}). Everything is working fine.The problem I'm having is as follows. A certain registration form uses an AJAX call to verify if an email is available as part of the form validation. This AJAX call is able to grab the csrf token from the rendered page, but that CSRF token is "used up" in this process. The request has now caused the middleware to generate a new CSRF token, and now the form (which was rendered two requests ago) has the wrong CSRF token.What are my options here? I was basically going to change the CSRF configuration so that only my actual form post routes are CSRF-protected and let the checkemail route (which only AJAX ever talks to) run without CSRF.How are others handling this?

Ideas for settings up and manipulating a queue system

For an small project I'm working on, I need to set up a queue system and rather than trial and error all the ideas I've had for doing it, I thought I'd ask for ideas. My stack is relatively simple. Node, Express, PUG view engine, MongoDB + MongooseAn application that might function similar to what I'm looking for would be like an email queue. You can add a new email to the queue, edit an email that's already in the queue, and re-order emails that are in the queue. Then a cron job would be scheduled to send out the next email in the queue. Again, I'm just looking for ideas about how to manage and persist the queue order.Currently, my best idea is to simple start a new DB collection with a single record. It would be an array of ID's, and it's order would be the order in which the queue would function. I could add a new item to the queue, and add it's ID to the array, move IDs within the array around to re-order the queue... etc....Anyone ever done something like this before?

I know that the server receives the requests (for http://127.0.0.1:8080/ and http://ift.tt/2zF5tal), because it writes to console.Failed to load http://ift.tt/2zF5tal: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8081' is therefore not allowed access.What I am doing wrong, please help !!!Thank you.

question about requests from node app with nginx on top

I have a nodeJS front end application that has nginx on top. The nginx is configured such that the the front end, as well as several other REST services are all under one domain. I.e. the front end would be site.com, and the services would be site.com/api/. The front end is simply calling ajax with a url without the whole host name...i.e. fetch('/api') I also need to make some calls on the front end's server side to the other services. However, with the request library, I cannot make a call without the full URL. I have two options.1) Set the full URL to be the common one that NGINX proxies all traffic from....i.e. my request on the front end server would to go site.com/api,2) I would call the actual URL of those services.Any advice? Thanks in advance.

Best practices for a Node API in production?

Hey all. I'm using NodeJS for a production API and have a few questions about "best practices" when it comes to memory settings.I'm using pm2 as a process manager and have "max_memory_restart" set to 3GB. This was needed to avoid out-of-memory exceptions during a particularly intensive cron job. (We're working on making this cron job less intensive)We set max_old_space_size to 4096 (aka 4.9gb) to avoid the out-of-memory exceptions mentioned above.This has fixed our issues with the cron job but our API will periodically go down for no reason at all. Are these settings to high?

We're close to launching a $5/1GB/20y web hosting with *limited* Node.js support. Care to test?

Hi everyone,So yeah, you got that right, we're seriously considering hosting a gigabyte of stuff for $5 for 20 years or around $0.02 a month. Because we want websites to stop disappearing from the web because you missed your monthly payment.Now obviously, we can't run a proper VPS for every user at that price and if we did we'd probably be lying about being ready to keep it up for 20 years. No less obvious is that pure static hosting is useless for many cases.So I came up with this idea to run server-side JS on demand. You get 5 seconds to start up, accept and process a HTTP request and clean up. Stateless, shared-nothing, like in good ol' PHP times. And if you need a database we have SQLite (also considering adding LevelDB).I duct-taped together two levels of LXC and several daemons in two days, and it does seem to work, but there are certainly problems (and possibly still some vulnerabilities). So I'm wondering if any one of you is interested in toying with this today, before the public launch (should happen within 2 days).Obviously, you get a free lifetime account for your efforts (valued at at least $5!!! :D).I don't want to disclose the name publicly yet, so I'll send you that and some instructions in a PM.Also feel free to ask me stuff.

How would I run a specific node service with elevated privileges Linux environment?

This is a question that is probably as much Linux-related as it is node-related, but I think this may be the best place to ask..I'm developing an app that is targeted at Raspberry Pi 3 running Raspbian Stretch-Lite (Ubuntu). For the most part, it's a straightforward web app, but I want my users to be able to configure the device's network settings and system time from the web app.It's going to be running in somewhat sensitive environments, so security is a big concern. What I'm thinking is that I write all of the standard CRUD stuff in one app, but have a second microservice running with elevated privileges that will be responsible only for the time/network configuration, minimizing the api surface area that is exposed with elevated privileges. I'd have both behind an Nginx reverse proxy to route requests to the correct instance.I'm planning on starting up my app instances with pm2. Is there a way that anyone knows of to use pm2 to spin up apps with different privilege levels? Is there a better way I can be going about this?Thanks in advance for any advice.

Lightweight WebSocket wrapper library with socket.io-like event handling, requests, and channels

Are you considering moving to native WebSockets? They work on all modern browsers, after all!This library might be useful if you want some socket.io functionality (i.e. event handling, namespaces, etc.), but you don't want all of the engine.io transports and lots of extra code in your project. This library just wraps a native WebSocket and handles some basic stuff for you: like message passing, event handler stuff, etc.When using this library in conjunction with a library like ws, your real-time web application can be pretty darn lightweight without giving up the nice bare-bones functionality you might find in Socket.io.Check it out! I'd love some feedback. Is it useful? Lame?

Architectural problems

Problem: I got a web portal where the end users are customers of my costumers. The web portal has a set of core functionality, but is still supposed to be tailored to the needs of multiple different customers.These customers are producers or retailers and have their own different products which their customers can interact with. What functionality that is connected to these individual products can vary from product to product, even though it's made by the same producer. The same goes for the required authorization level to access some of these functionalities.My question is how do you structure for such a high grade of variation? Should it be done at database level, backend or frontend?I'd prefer a method that isn't to complex, but still flexible. Atm I have done a lot of these adaptations on database level, each product knows what functionality is connected to it based on table data. And based on this different functionality is displayed in my React frontend, however I'm unsure if this is an unhealthy way to structure the project? Seems like all options got pros and cons.

Hi all.Say that I'm building a note taking app. There's a Node.js Express server exposing a REST API, a web app and both an Electron desktop app and an Android/iOS React Native app.What would you use to store and sync data between all the clients and the server? I've looked into Realm but the pricing is insane (starts at $1750/mo for the server component), Firebase but it doesn't seem to include a way to persist data for the Electron app, MongoDB but it seems that I'd need to write the whole sync logic by myself. How would you address this?Thanks!EDIT: what db engine would you use on the server, on the desktop app and in the mobile apps? As the app should work offline as well, at a high level, how would you implement sync and deal with potential conflicts?

You-Dont-Know-Js equivalent for Node.js?

I learned JavaScript from You-Dont-Know-JS and I loved this course, it was very exhaustive, very clear and made me very confident with JavaScript.I was hoping if there exists equivalent Node.js tutorial that should be like the tutorial for JavaScript -- free, text-only (not interactive like NodeSchool's tutorial), very exhaustive that teaches from very basic to advanced level.If you know please let me know and vote this post up for others.Thanks!

Multiple socket.io connection for the same page?

Hey all I need some serious help ahaha.So I am trying to create a real time message app using socket.io,express and AngularJS and it has been going well. I need to emit a private message to a socket user but it never catches the"on" event (If I emit to all sockets it works). After abit of debugging I noticed that when I first launch my app there are multiple socket connections for the same page. A exmaple of the code is below://Listen on the connection for incoming sockets io.on('connection',function (socket) { console.log("New new connection has been started");From the above console log I get the following:listening on *:3000 New new connection has been startedNew new connection has been startedNew new connection has been startedNew new connection has been startedNew new connection has been startedI have no idea why this is happening!

Nodejs, CSV and Cron?

I'm trying to write a node app that will read a csv file and update each row at a setinterval to a mongo database.For Example, I have a csv file with 2000 rows and I’d like each row to be updated to my db once a day.I followed this tutorial to upload a csv file to my mongodb database: http://ift.tt/2z9KVTj but all that does is update my DB with all the files that I upload and it displays immediately on my page.My goal is to have each author on the csv displayed once per day until there are no more authors.What is the best practice to have the csv file read row by row to update my collection? Or rather, display a document at a set interval?Ultimately I would like to utilize my raspberry pi to have this run automatically.Sorry if this such question has been asked before or if this is the wrong subreddit, I'm rather new to development. I've read up on cron jobs and crontabs and looked at a few videos regarding this, but beyond that, I’m kind of lost and any help would be appreciated.

Clean node module cache and re-require?

I have a node module that automates certain build processes and instantiates some classes. I want to hook this up with a gulp.watch, but it only builds the first time. I'm assuming this is because of the way my build system caches changes, and it isn't re-instantiating the classes. Running it fresh works every time.Is there a standard way of dealing with this? Is there some kind of design paradigm I can use to avoid this situation, or am I going to have to do some trickery with the cache?

Starting out with Node+Express+React - do I need another server-side templating language at all, or can I just use React?

I'm a PHP dev (been doing webdev on and off for 18 years), who so far pretty much just knows enough JS to do typical stuff with JQuery. I'm diving head on into completely switching over to Express for backend, and React for frontend over the coming year.When I create my first Express project (using express-generator), I'm given the choice of which templating language I want to to use on the backend: ejs|hbs|hjs|jade|pug|twig|vashGiven that I want to dive into using React for both client-side and server-side rendering for the most part... does it still make sense to use one of the above templating systems for the general backend site-wide layout rendering for the core stuff like global header/footer/menu, meta tags etc? ...if so, keen on opinions comparing them.Or can I ignore them altogether and do all templating in React?I know there's probably no binary right/wrong answer here, so I'm mostly after opinions... What would you recommend?Also I'm guessing that I might kind of be comparing apples to oranges here, as React mostly serves a different purpose to most templating systems, especially regarding "page rendering (this part is the core of my question)" -vs- "building interactive applications"... but I'm just wondering if there is a good enough case to use React for both purposes... or if I'm just making things harder for myself?In case it's relevant, my personal situation is that I do have quite a bit of time to learn right now, and I'm mostly going to my building my own sites, so I don't need to work with other devs. But they will be fairly large projects and I'll be continuing to build upon over the next 10 years. Some sites/pages will have complete pages rendered server-side, and some will be a mix with client-side rendering.I know there's other similar threads asking for advice on which Express templating option to pick, but I'm keen for current opinions, especially on the "can React replace them altogether?" thing.Also if you happen to have any random tips that could come in handy for an immigrant from PHP-land, please feel free to chuck them in! It feels like there's so many different frameworks etc I need to learn to just get started in this new JS/Node world.

Looking for Help with PowerBI Custom Vis

Good morning!I'm trying to get a custom visualization made for PowerBI to visualize SQL Server Agent jobs. I can provide the SQL data in whatever format necessary (including the PowerBI Query results in table form for testing), and take care of the DAX required for measures.It would basically be a Gantt chart, but with recurring activities, several options for colorization, shading, grouping and visibility. X Axis would be a timeline, zoomable all the way from 9 days (week plus a day on each side) into probably a minute increment. Y axis would have a horizontal Bar for each group of data, starting with the Server, drilling into the Job Category, finally drilling to the Job Name. Each data point would be based on a starttime and expected duration for that specific job. So a job that runs every 5 minutes, for 10s would look like Start: 8am Duration 10s ; Start: 8:05am Duration 10s etc... Those would be represented on the timeline as a single bar, with colored space while running, and no color when not running. At the bottom, it would have a bar showing the timing overlap for jobs at that level of drill, letting you know where you can deconflict. It might also take into account history of the job, showing success/failure and actual duration (color code for long running jobs) - depending on how hard it is to add.From what I've read, Custom Visualizations are programmed in node.js - which I know nothing about. I'm a database guy. Is anyone willing to collaborate on an open-source, free visualization for the PowerBI and SQL community? Mods if this is the wrong place, please let me know where I could post this. Thanks!

Handling scrypt callback

Hello,I'm currently working on implementing a passport.js-based implementation of local-authentication in my server.Unfortunately, I'm pretty new to nodejs, so I'm having troubles understanding how to properly implement the scrypt.kdf() function. I only need the result of the function, but if I did it synchronously the program would stop working for at least 3ms while it hashes the string... Which (I think?) is unacceptable.In C# I would probably do it in a new thread. I don't think that's how I should do it in node, but I'm lost with the callback.I have a user object that should be saved in mongodb. I understand how to set the rest of the properties, I'm only lost with the scrypt.kdf() async function.Should I do it with promises?

So, it took quite a long time to finish.A mentor/tutor would allow me to spot problems/explain what I don't understand in a much more time-efficient manner.The reason I find it important is because I have a full time job, where I travel between countries and can't commit to a face-to-face course, because I simply won't be there half of the time.I'm based in Europe, so some courses that offer online support/video sessions don't work very well with timezones, because if they're done in the evening, it's night time over here.A paid solution is completely fine, as long as it's not astronomical... Would be really grateful for your suggestions, thanks!P.S. Currently reading Eloquent Javascript, and doing some codeacademy courses.

Can we talk about hot failover to a second machine?

I've been required to add redundancy to one of my installations. Basically, an entire second Linux machine sitting there waiting for the first one to fail.My project has a bunch of data collecting node processes all talking to other networked devices and writing to a local mongo database. Since I have a could-based supervisor, that now gives me 3 nodes, so I can replicate mongo data fairly easily.So, what sort of tool or mechanism should I use to figure out when to tell the secondary server to start all the node processes, after noticing the primary has failed.I could write my own scripts, and use pm2 to start and stop things, but I was wondering if this problem has already been solved, by things like Heartbeat, or some clever npm package that I can't seem to successfully google for.

Anything new for security best practices in 2017 for express?

Currently creating a new boiler-plate with express to help start projects. For the security side of things, is everyone using Helmut and/or Lusca? Lusca seems to be the better option as it has more features.Am I missing anything?SSL/TLS using NGINX as proxy severLusca for CSRF, XSS, clickjacking and a bunch of other thingsPassport for logins.User-access - still not sure what to use here. Previously I always used sessions and cookies.Anything else? Doesn't seem like much has changed over the past few years.Thanks!

Serving React (sub) app on a specific route with Express

Well, I was wondering what's the best way to manage sub apps with express? For example, I'm trying to make a web application / site with administration panel and I wanted a panel to be a completely independent app (with it's client side framework like react, libraries, static files and so on) from which I'll be able to control main app (app that's being serverd on root route). Root route app has nothing to with react and stuff.So I was thinking about creating a route for my panel app, something like /panel or /admin and serving a react app on that route. Problem is I don't know how to do it properly, I mean I started something but I wanna be sure in the start that I am doing the right thing.EDIT: (well, that was quick)I found something like this on a blog. I think it suits my needs.var express = require("express"); // sub-apps var sub1 = express(); sub1.get("/", function(req, res){ res.json({status: "SUCCESS!!!!!!"}); }); var sub2 = express(); sub2.get("/", function(req, res){ res.json({ foo: "bar", baz: "quux" }); }); // main app var app = express(); app.use("/foo", sub2); app.use("/", sub1);

Alternative to Loggly

We have been shipping our logs using Bunyan and Loggly and I was wondering if anyone had a better experience with another logging service. The interface for Loggly is clunky and I find the filtering difficult to use. Does anyone have suggestions for nodeJS specific logging? We don't really need it to be system/language agnostic, we just need something that has a simpler interface and a better query language(NOT Apache Lucene)

How to perform some synchronous stuff

I learned that a big part of node is asynchronous. Are there ways to handle things synchronously? For example, can we wait until a database request is complete and then do something else? Like, store the result in a variable?In some cases, the object/array returned by the database result is not how I want it and so I have to build an object according to my preference. In other cases, where a loop is involved and inside the loop, there is async happening and unable to store the data returned outside of the loop.1st example.app.get('/dbstuff', function(req, resp) { var results = []; connection.connect(function(err) { db.query('SELECT * FROM employee', function(err, result) { for (let item of result.recordset) { results.push(item); // don't ask me why I would do this, I just want to know if it's possible } }); } console.log(results); // undefined }); 2nd examplesomeModule.emloyees(err, employees) { // a module that gets all employees var empId = [1, 4, 6]; // the employees I want to return var emp = {}; for (let employee of employees) { if (empId.indexOf(employee.id) >= 0) { someModule.employee(employee.id).get('name', 'department', function(err, emp) { // this is happening async emp['name'] = emp.fields.name; emp['dept'] = emp.fields.department; }); } // sadly, I cannot resp.send here so I have to build my obj } console.log(emp); // but it's undefined }); This would be useful for those who are also learning node.

Electron User authentication

I am developing an app that so fat features a window with a login and signup form, rendered in an electron window. On submitting, all the user is gathered(email, password, name etc) How will someone try and authenticate this user? My main idea will be to have a server and a database. This server implements REST API. On submitting, the data will be sent to a route, via a POST request, for example http://localhost:8000/signup, and the server will comapre this data with the data base. My question is how can I validate this data? What is the best approach? Should I validate the data in the electron window, then send it to the server, or should I send the data directly, and let the server handle the validation. I want to do this the best possible way, and elegantly. Has anyone developed a user signup/ login form, and can give me some advice? Thank you.

Is this a common practice?

There was also the following error that came from the front side:Uncaught ReferenceError: process is not definedWhich came from:socket = io.connect(process.env.PORT || 3000);Also I posted this mini project to heroku in case you guys want a better look: http://ift.tt/2i3uD7J (inspect element, go into sources, then open up sketch.js to see the error)Here's the server.js code:var express = require('express'); var app = express(); var server = app.listen(process.env.PORT || 3000); app.use(express.static('public')); console.log('Server running'); var socket = require('socket.io'); var io = socket(server); io.sockets.on('connection', newConnection); function newConnection(socket){ socket.on('mouse', mouseMsg); function mouseMsg(data){ socket.broadcast.emit('mouse', data); } } Any ideas on what I should do to make this thing work on heroku? (This app worked perfectly fine on localhost when I didn't have the 'process.env.PORT' there and just had my ip followed by the 3000 port.)

Help! Mysterious read stream behaviour sync vs async.

Hello. I have been playing with implementing my own readable streams recently, usually for reading an API until some condition is met or the like.My problem is that I seem to have stumbled on two different behaviours depending on whether the _read() method is synchronous and async.In the docs it says: When readable._read() is called, if data is available from the resource, the implementation should begin pushing that data into the read queue using the this.push(dataChunk) method. _read() should continue reading from the resource and pushing data until readable.push() returns false. Only when _read() is called again after it has stopped should it resume pushing additional data onto the queue.Note: Once the readable._read() method has been called, it will not be called again until the readable.push() method is called.Which makes me think we should push data until the buffer is full. with is a synchronous implementation this seems to work fine.Suppose we implement a non stop stream of integers. (I wont include the whole class boilerplate just the _read implementations)// this.i equals 0_read() { let ok = true; while(ok) { ok = this.push(this.i); this.i += 1; } } Then this would work as expected. The control flow stays inside the while loop. However suppose we were getting these numbers asynchronously,_read() { Promise.resolve() .then(() => { let ok = true; while(ok) { this.push(this.i); this.i += 1; } }); } as soon as this.push is called the another _read() is called and another promise is created before we even increment our this.i Even worse, suppose there was an initial push..._read() { this.push('first'); Promise.resolve() .then(() => this.push('second')); } "second" will never be pushed. This is understandable if you assume the this.push itself call an internal this._read()... However that is not what is happening in the synchronous version, the function will end before a new one is called.In the end the rule I have made for myself to get reliable asynchronous read streams is to only allow one push per _read() and make that push the last operation of that read. if there are any state changes to make do it before pushing, or better yet abstract state away inside a closure like inside a generator.However this behaviour seems a little erratic, and if anyone who understands stream internals can explain this away I will be very thankful. Thanks.(ps. I know this are not real world examples, but only there to demonstrate control flow, or for anyone who wants to try)

How do you manage npm tokens?

We have a private npm repository, hosted on npmjs.com. In order for CI users to install npm dependencies from our private repo, they need to have access to an npm token.You can create a new token by running npm login, and then checking your .npmrc file. But how do you manage all the tokens you've created? I don't see any way to associate a token with an application/user.And if I create tokens with my personal account credentials, what happens if I leave the company? Or say npm discloses some security leak, and we want to recreate all our tokens? How do we manage this?Also, it looks like if a user changes their account password, all their npm tokens are wiped clean.It seems like it would make more sense to have the CI user login to npm o every build, so we don't need to hardcode the tokens. But I don't see any non-interactive way to login.

I'm complete shit at NodeJS. A noob. I've been using RapidMiner for API calls but it's even more frustrating....Can you wrap this in async.each properly for me? It's for my master's thesis on media bias! Just connect the input array urls to the source: in rapid.call !!var array = fs.readFileSync('Kairos.js', 'utf8').toString().split("\n");> async.each (array, rapid.call ?!?!, console.log ??!?!) {setTimeout(function() {rapid.call('KairosAPI', 'createEmotionalAnalysis', {'source': array[i], }).on('success', (payload)=>{ console.log(array[i]); console.log(JSON.stringify(payload)); return; }).on('error', (payload)=>{ console.log(array[i]); console.log(JSON.stringify(payload)); return; }); }, 1500 * i) // With each iteration, the delay increases}If you wrap it correctly once I can re-use it on tons of apis... ~~ <3333 plzzzzz help1! Bonus points if you fix it so the URLs or iteration are returned alongside the stringify(payload) ~~ Whoever helps i'll give you 100k karma, promise!~
