Help with database query - can I un-async it?

I'm about to defenestrate this computer, so forgive the wall of text please.I've had this problem before twice. The first time, it was because the returned object was actually an unfulfilled promise, and I was able to get around it by throwing all my code inside of the block so that it would execute in there. Not exactly an ideal solution but it worked and I was in a hurry.The second time I was using pg-promise instead of just pg, and when this issue popped up I thought "it must be that damn promise again", so instead of tearing my hair out I just uninstalled pg-promise and went with the regular postgres package for nodejs instead. Well, the problem is still here and I'm tearing my hair out.I'm making an API. I have a controller with functions such as getPayment and postPayment and so on. At some point in these functions, I need to get information from or into the database. In another file, which I called postgres.js, I have a connection to the database and then functions which I can call to insert data, select, etc. Here is postgres.js as it is right now (this works but only for printing to console):module.exports = { select: select }; const { Client } = require('pg'); const client = new Client({ user: 'myUser', host: 'localhost', database: 'myDB', password: 'myPassword', port: 5432, }); client.connect(); function select(){ client.query('SELECT * FROM payments', (err, res) => { console.log(err ? err.stack : res.rows[0].id); client.end(); }); } As you can see right now all it does is get the payments from the table and print a value (in this case, the first row's id) to console. Here is the code that calls this function, from the controller (payments.js):var pg = require('../../config/postgres.js') ... function getPaymentInfo(params){ // get info from the DB // disregard the fact that I'm not sending any params right now, this is for testing var result = pg.select(); console.log(result); console.log(typeof result); } Calling pg.select() does in fact activate the select function on postgres.js (and the console log correctly prints the data in res.rows[0].id) however when I try putting a return res.rows[0].id there in order to actually return the information that was retrieved from the database, what comes back into the var result is "undefined" according to the console. Here are a few examples of things I've tried to do to get the data out:function select(){ var i = ''; client.query('SELECT * FROM payments', (err, res) => { //console.log(err ? err.stack : res.rows[0].id); i = err? err.stack : res.rows[0].id; client.end(); }); return i; } I tried this with and without commenting the console.log line, either way it doesn't work.function select(){ client.query('SELECT * FROM payments', (err, res) => { //console.log(err ? err.stack : res.rows[0].id); return err ? err.stack : res.rows[0].id; //client.end(); }); } Instead of printing t console, just return the result of that little error check up there... returns undefined.function select(){ return client.query('SELECT * FROM payments', (err, res) => { //console.log(err ? err.stack : res.rows[0].id); // Hello World! client.end(); return err ? err.stack : res.rows[0].id; }); } Returning the return from client.query(etc etc);.. same thing as before. Also tried without the explicit return, without checking for error, all the same.Here's the last test I tried:function select(){ var i = 'original i'; client.query('SELECT * FROM payments', (err, res) => { console.log(err ? err.stack : res.rows[0].id); // Hello World! if (err){ i = "i has changed!"; } else { i = "i has not changed!"; } client.end(); }); return i; } The console shows this:original i string 2 That last "2" being res.rows[0].id.I really believe this must have something to do with the blasted "promises" and asyncronous stuff. But my previous "solution" won't fit here. I can't just do everything inside of that block where I have access to res. I have to be able to return some data back to getPaymentInfo().It seems that client.query(...) is waiting for every line in getPaymentInfo() to be ran before actually doing anything. I can see that because in the console, the results of console.log(result) and console.log(typeof result) appear before the line that shows information from the table (from console.log(err ? err.stack : res.rows[0].id) ). That is absolutely infuriating.I saw some examples out there that used await, but when I tried to add that copying the examples, it gave me a syntax error as if it didn't recognize what await is supposed to be. There was an example with yield as well, same error. It doesn't know what those commands mean. I'm using the latest version of nodejs (v8.10.0).I also tried using then to get it to wait:function generatePaymentInfo(params){ ... pg.select().then(function(v) { console.log(v); }); ... } It gives me this error:TypeError: Cannot read property 'then' of undefined What's going on here? How do I get it to do things in the right order? All I want is to get some information from a table. Every example for the pg package (and pg-promise as well) I see out there just has a console.log() representing "success". In reality what anyone would want is to have actual access to the data. The level of shenanigans going on here is officially too much. This isn't AJAX. I don't need this to be asynchronous! It's all happening in the server! It could very well go in there, get the data, return it, and keep going just how god intended it to! But how??

How do you optimally structure a MongoDB database to fetch all properties of a user?

I'm building an app where a user object has multiple game objects. What would be the proper strategy for fetching all of a user's games from a mongoDB database?As far as I can tell I have 2 options:1: One option is to give users a game property that is an array of ids of games that the user has and then fetch each game individuallye.g.example user{ _id: '1342', name: 'Dave', games: [ '12345678', 'fgnhe45rnd', ], }example game{ _id: '12345678', name: 'Fluxx', }2: The opposite. Give each game a users property that is an array of ids of users that own that game. Then fetch all games that have a specific user's id.e.g. example user{ _id: '1342', name: 'Dave', }example game{ _id: '12345678', name: 'Fluxx', users: [ '1342', '5783', ], }Any advice is appreciated. Thank you.

How many hours to learn NodeJS as an experienced PHP MVC/ReactJS dev?

It's a question that gets asked a lot "How long to learn...?", but I wanted to ask when giving some more details of my previous experience.Title says it all really - I have quite extensive experience in PHP MVC (Yii2), ReactJS/Redux, jQuery, vanilla JS, MySQL/RDBMS etc. I am building a new app in PHP with a React frontend which is nearing completion. However, while developing it I have been using AWS for the first time and looking more and more into backend/server technologies and language performance. I am starting to think NodeJS is the way forward and I might look to transition this new app into Node/Express once I have the initial PHP version up and running.Realistically speaking, how many hours am I looking at to reach a professional-level proficiency in Node? I am a dedicated learner, putting 2-3 hours (or more) aside each day (7 days a week) to learn Node shouldn't be an issue.Also, how good/intuitive is Sequalize as an ORM?

How to test number of HTTP requests an API can handle per minute

I want to test how many requests my API (an express app run locally) can handle per second. I wrote a bash script which calls 'curl' to the API in a loop and takes an argument designating the number of curl calls. However, I think the bottleneck is on the testing end. I don't think I'm seeing the amount of API calls the API can handle, but rather the amount of calls my local machine can generate. Is there a simple way to test an API like this? Is there a test framework that can generate high volumes of calls?

code generation vs config file (app generator)??

I wonder how Dialogflow (or other services) stores their users' config and generate each app for each user config.Does it generate code for each user or does it just save each config and pass it to the central app which has so many conditional checking like if(userOption == "enabled"){}.Which is the most optimized way to automatically create each app for each user? Is it by code generation (generating javascript files for each user which has its own link) or config file (generating app by central app which does many conditional checking for each user config)? I'm trying to build one for my project. Take Dialogflow as the case study if you think the answer is too broad. It'll be great if the factors to choose which way are explained.

Puppeteer versus "I am not a robot"

I am really interested in automation so I've started studying puppeteer today and am slowly gaining an understanding of how it works. and this got me thinking about the often seen "I am not a robot" box that you sometimes have to click with filling in a form, registering etc. Like I said I've only been studying puppeteer for a couple of hours but it seems to me that it should be fairly simple to write scripts that can beat that "I am not a robot" checkbox.I would think you could easily inspect the checkbox to get its id or other CSS identifier and then do something like:await page.click("#checkbox"); but if that's true that would mean the "I am not a robot" security measure that is used so often is a complete joke..

When to use RS256 for JWT?

So, right now I'm building an API for third parties uses and I was reading about RS256 and HS256. What I understood was that diff between is that in the first one you use a public key to verify and a private key to sign, and the other one, use just one key.. So what I don't understand why you would like to verify the token in the client? Because you do a post request to the server, then it sends you back the token and whenever you want to make an authorized request you just use the token and the server verifies the token. So, why you would like to verify the token in the client? I thought it was a backend's duty.I think maybe I'm wrong in something, hope you help clear this. Thanks.

Nodejs - avoid blocking the event loop

I have reading a lot about the event loop in Nodejs, the fact that it is "single threaded" and that you should not block the event loop.I am trying to understand if Node.js is a good choice for the following scenario, because I guess I still haven't figured that out.I have sensors that every 5 minutes collect some data (for instance, think of the temperature) and then send data to the server. When the sensors are online, no problem. They send very little information (basically the body can be summarized as [timestamp, sensor_id, temperature]). The sensors retain the data up to a certain amount of time (depends from sensor to sensor, could be like 6 months). Unfortunately, these sensors are not reliable and it could happen they they get stuck, blocked, or, anyway, for whatever reason, they are not able to send data for a certain period of time. The period of time could even be months long (i'm not gonna explain why, it's bullshit, but that is what it is).The sensors are not-so-smart. If they were blocked, whenever they go back online they send everything they didn't send in a single , one-time, POST request to the server.The point is, the server receives the requests and has to do some work on every single data contained in the body before writing it into the database. The work is simple but it's a CPU operation (it's just a simple sum), nothing really CPU-intensive like AI or whatever else. This means that the computational complecity is O(n), so it grows linearly with the number elements of the body.Most of the times the requests are super simple and short and contain a single data record, so the complexity is basically O(1), but when it happens that a sensor sends a huge packet, the backend would have to loop over it and this would block the event loop thus making the server unresponsive.I am wondering what would be the good and proper way to handle such a load using Nodejs.Any suggestion is appreciated in order to seek the best solution and learn Nodejs better.

Objection.js (or rather, knex schema builder)

So I've been using objection.js for a while, and I've read in their API:Create database schema. You should use knex migration files to do this.So I looked into the knex migrations and I have some issues. I've already posted this to their github, with lackluster response.tl;dr: I was using knex migrations for an app with this schema (give or take) representing my database:exports.up = function (knex, Promise) { return knex.schema .createTable('servers', function (table) { table.increments('id').primary(); table.string('serverName', 50); table.integer('fault_id').references('faults.id'); }) .createTable('faults', function (table) { table.increments('id').primary(); table.text('faultDescription', 'longtext'); }); }; exports.down = function (knex, Promise) { return knex.schema .dropTable('servers') .dropTable('faults'); }; I've been using this database for a while now and I have lots of data already in the database. Now I want to add another column to the servers table, using knex migrations.If I run knex migrate:rollback I've lost all the data. If I change the schema and run knex migrate:latest I get an error that it's already up to date. If I create a new schema with alterTable, I've lost reference to the schema above. I literally don't see a way of using schema migrate to solve this issue.What is the correct approach?

I mean, I know that I need to include passport and the strategy I will use, but there's no high level overview of things to do with passport.I guess the questions lingering in my mind are:where do we put the Passport.use statements so that express will know that passport is being used? right in the middleware stack? (Ex: app.use(passport());??)what routes should be available for the purpose of sign-in/Registration? (Ex. GET/POST for /register, /login)What steps should be taken in these routes?(ex. check for user in DB, compare password, re-route to protected route after authentication, etc....)What should the app be doing during an authentication enabled route? (so I can understand what my app is doing during the process, for debugging purposes.)Not sure I've asked everything, and I'm sure I'm not the only one that has these types of questions. I can understand that no one really has this completely figured out, but something as popular as Passport should be documented, regardless of whether it's officially marked down.There has to be an explanation somewhere. Resources for answering the questions are good too.

Using the real info from the first object:

This is a reply to comment ID 1(the comment above)

Cannot for the life of me figure out how to use Jade.

Hey guys,So I'm running a basic Express webserver that I copied off of the internet. I wanted to use PHP includes but quickly realized that that's not really how node.js rolls. Found out that this "templating engine" called jade can accomplish something similar to php includes, and it's already on my webserver, great!I have absolutely no idea how to get it to work. So right now my website is a bunch of html, js, and css files in the "public" directory. On a PHP server, all you do is change the extension to ".php" instead of ".html" - this is not how Jade works. Jade runs off of a "views" folder and I have no clue what to do with it. Do I change all the extensions to ".jade" and move everything into the views folder? What am I meant to do here??

Completely lost on running my apps. Tried AWS, but now they claim no space left on device. What do I do?

So, basically, I am familiar with programming with node.js. I have made a twitter bot that runs with node.js and runs on AWS. I already got it running.Well, I tried to create another app (another twitter bot for fun), but when I try to make a new folder on it and then "npm install" the needed files, I get the message "No space left on device".Well, honestly, I have no idea how much space I have on my account, no idea how to even tell what the issue is, and no idea on how to work around this.I am assuming it it saying that the files I have are too much for my account. But, no idea how to work around that.Has anyone run into this? Is there a way to run node apps that rely on libraries to run without using a lot of memory or storage on AWS? I am just confused why this take so much space on my account.Sorry, I'm new to this and just familiar with AWS because we used it in one of my classes in college. Thanks for any help with this.

How do I sort my comments/replies/replies to replies data properly

I am using Nodejs, Express, MySQL, EJS.Users are able to create posts and comment/reply to comments/reply to replies on those posts.The problem: I don't know how to sort the data into objects/arrays in a way that will allow me to render them in EJS. I know how to do it for comments and replies to the comments, but not to replies to replies. How to create an object/array(or objects/arrays) which will make it "easier/simpler" to manage the comments, replies and replies of replies of replies(...etc)?The idea: I believe the end product should look something like this:When rendering EJS, it will check the sorted data for comments, if there are comments, it will create 1 container div for that single comment(and for the replies of that single comment), each other comment will have it's own container div.In that container div, will be the main comment div which will contain only the comment.Below the comment div will be the replies to the comment div(maybe the replies to replies will be stored here too, or a div specifically for that will be created)(I don't need to do it in this way, you are allowed to do it in your own way, I just think this is not a bad way to do it)The "comments" MySQL table is: ID comment ReplyToCommentID -------------------------------------------------------- 1 | First Updated Comment | NULL 2 | Second Comment | NULL 3 | Third Comment | NULL 4 | 4th Comment | NULL 5 | This is a reply to comment ID 1 | 1 6 | Reply to Comment ID 4 | 4 7 | Testing here | NULL 8 | TriHard 7 comment id 7 | NULL The value in ReplyToCommentID means that comment is a reply to the comment with the ID of that value, the comments with ID 5 and 6 are replies to the comments with ID 1 and 4, if it's NULL, it means it's a normal comment to the post.Getting them from MySQL to Node returns them in this format: [{"id":1,"comment":"First Updated Comment","ReplyToCommentID":null},{"id":2,"comment":"Second Comment","ReplyToCommentID":null},{"id":3,"comment":"Third Comment","ReplyToCommentID":null},{"id":4,"comment":"4th Comment","ReplyToCommentID":null},{"id":5,"comment":"This is a reply to comment ID 1","ReplyToCommentID":1}, {"id":6,"comment":"Reply to Comment ID 4","ReplyToCommentID":4},{"id":7,"comment":"Testing here","ReplyToCommentID":null}, {"id":8,"comment":"TriHard 7 comment id 7","ReplyToCommentID":null}] Separating the comments and replies into their own object gives this. (Obviously) this is replies {"1":"This is a reply to comment ID 1","4":"Reply to Comment ID 4"} This is comments {"1":"First Updated Comment","2":"Second Comment","3":"Third Comment","4":"4th Comment","7":"Testing here","8":"TriHard 7 comment id 7"} I have spent a couple of days trying to figure this out, but it seems it's too much for my "student experience". (I am self-taught so I don't have someone to ask for help in real life)I would be very thankful if you help me with this.Thank you for your time.

Keep production Rest API files up to date

Hey everyone. I couldn't find a proper way to keep my node.js/expresd Rest API app's files up to date on my server. So for the moment I'm manually copy-pasting updated files.What should I do so that when I push my code to github (private repo) it automatically pushes the files on the server as well? Or maybe a command that is not even linked to the GitHub push, I'm just looking for a simpler way than copy-pasting.Edit:Ok I found something. Basically, I just have to setup another repo on my server, and push files there.This have crossed my mind, of course, but I thought maybe there was a better way.

How to position a reply to a comment depending if they share the same ID

I am using NodeJS, Express, MySQL and EJS.I have a 'posts' and a 'comments' table.The comments table has: ID, comment, ReplyToCommentID columns. If replyToID is a number, it means that it's a reply to the comment with that ID, if it's NULL, it means it's a regular comment.The problem: How do I display the replies to the comment with the same ID (or div value) as the ReplyToCommentID?I need something like:Creates the container div(which contains the div of the comment and possibly the replies) Creates the comment div Checks all the reply id's to see if the just made comment div's id is == with any of the reply id if true, create the div of the reply I imagine it would look like this:

Comment Here

<% if(the div's id above is == with some ReplyToCommentID){ %>

Reply here which has the same ReplyToCommentID value as the comment div

<% } %>

Trying to use document.querySelector in a <%= or <% - %> or script tag results in an error.

Question to Express API response

Hey,I've build an API to post data with express.It is just a query to my DB for now. If I start the query from my web page the query will be on "pending" all the time. It loads, loads and loads. Everything I've sent to update in my db is updated, but for some reasons on my webpage it is still pending.heres some code: router.post('/test/clear', (req, res) => { var sql_test= "UPDATE test SET ? = '' WHERE name = ?"; pool.getConnection((err, con) => { pool.query(sql_test, [db_col, obj.clear.test], function(err, results) { if(err) throw err; else { res.statusCode = 201; res.json(results); } }); con.release(); }); }); I tried to google my problem and tried to solve my problem with sending something back within my "else", but after saving it just shows the json, instead of the webpage. My goal is to not reload the webpage after saving and not having a pending status. Do you know how to fix this problem?

Full stack integration testing with node?

Firstly, a couple of things to preface this with. I have asked this before, though not too recently. And I am a Java developer who's a big automated testing fan.I'm trying to work out the best ways, if possible, to perform integration testing of the full system. The goal here is 100% confidence at the end of yarn test the everything works. By "everything" I mean:All unit testsDatabase migrationsDAOs, against a real databaseREST APIs, all the way to the database and backEtcI also want to do all of this with the minimal amount of setup. I'd like it to be yarn install && yarn test, and that does everything necessary. No needing to install databases locally, and configure the build to point to them, and so on. That's not reproducible, and is a huge way to introduce errors.In the Java world, I achieve this using things like http://ift.tt/2aztOAh to run s database server up in-process and test against that. And it works great.My assumption is that the best way to achieve this would be docker. In particular, I've found the dockerode module that I think will let me start and stop containers.Is this the best way to tackle this? Or are there other, easier ways that people use?

I need some help getting CI/CD working with my new todomvc example app, how can I automate my deployment processes using gitlab ci/cd?

Alright so I have a SailsJs 0.12 app that I am writing right now which will be containerized to help me learn about dockerized nodejs apps and a more automated workflow for CI/CD.Traditionally, i was using codeship that had ssh keys stored, and given a successful test, it would ssh into the production server, cd to the apps directory, git pull, then restart the nodejs app via pm2.Now that I am going to dockerized setup with this new example app, I am not sure how to go about automating the workflow.I am using gitlab-ee with gitlab-runners running so it spins up a docker container for each trigger.Right now I have the following separate containers in a docker-compose.yml:MySQLRedisSailsJs 0.12 running on node 9.5.0nginx - handles reverse proxy of the sails app, and eventual host for the React SPA codeMy gitlab-ci.yml right now is setup for the sails app to simply run yarn install && yarn run test off of the sails app's latest code.I imagine the workflow would be something like this...hack away, boom! code is now ready for 1.0push code to masterpipeline gets triggered in gitlab to test, build, then deployI got the testing part working, its pretty simple gitlab just runs yarn run test off the last commitafter all the tests pass, is where I start to get lost. I imagine with docker containers you just need to build a new image with a new tag (tag latest, or tag v1.0?)git clone the repo (is this even needed?) or can i just skip to docker buildrun docker build . -t todomvc-api:latestrun docker push registry.example.com/ndboost/todomvc-api:latestThe other part I am also confused about is the deploy part, how do i get my production server to pull the new image once its built? Do i need to ssh into the host to trigger the docker commands and restart the container with the new image? Or will something like v2tec/watchtower that would detect the push to registry.example.com for my todomvc-api image and then pull it and restart the container automatically?

Serving images from an express app to a frontend.

Hi,I am building a little VUE.js app and using a decoupled NODE.js/Express backend.I have a user profile where the user can upload images, which I achieve with Multer.This works great but now I need to server those images, currently I am making a request to get the users details and then I also get the path to the image but the problem is that the client is served on http://localhost:8080/ whilst my Restful API runs on http://localhost:8081.Any idea how I can actually serve the image on my front end?I can do a fetch request to the absolute url and then convert the file to base64 but does not feel like the right way to go about it.I have my static folder on Express setup, so a get request to the image works but how do I convert that to a usable image url?Thanks!

Deploy App to Production

I have an “App” I’ve written with a backend API in Express and frontend in React.I wondered how to deploy this to a normal server rather than Heroku and how to do this with say TravisCIThe idea I have is to use PM2 to run the index.js for both client and server? Will this work?Is there a better way to do this?

Updating data in my database without reloading the page from EJS

I am creating something like the reddit comment section, someone can comment something and people can reply to that comment.I am using Node, Express, MySQL, EJS.The problem: I don't know how to make the upvote/downvote part, I don't know how to make an onclick event which will tell my DB to upvote/downvote that comment by 1 without reloading the page.Express code: app.get("/posts", function(req,res){ connection.query(`SELECT post FROM testingposts`, function(error,result){ if(error){ console.log(`error 757`) } else { console.log(`works btw`) res.render("posts", {result: result }) } }) }) app.post("/posts", function(req,res){ let post = req.body.post; console.log(`req.body`) console.log(req.body.theValue) connection.query(`INSERT INTO testingposts(post) VALUES(?)`, [req.body.post], function(error,result){ if(error){ console.log(`error 555`) } else { res.redirect("/posts") } }) }) EJS: //This part basically creates the html elements for the comments. //But I haven't added the upvote/downvote elements yet. <% for(let i = 0; i < result.length; i++){ %>

<%= result[i].post %>

<% } %>I tried trying something with Fetch, but it didn't work properly for me.(I don't know what to write as the URL)

What technology/language/framework should I use?

Hi! I am a beginner in programming and I have an idea of building an audiobook platform or web app for my place where I live. Now I know basics of HTML, CSS, PHP (got basics of oop covered, know a bit about mvc frameworks, still not as good as I think a php dev should be). I am in 9th grade (lol) so I am not in any kind of hurry. I want to learn most flexible and scaleable but fast but good but friendly language (I know that that doesn't exist).So I would like to add secured audio files to a server so people can listen to it but so they can't easily steal my stuff. Thinking about PWA app (I am a big thinker) but you'll get me confused if you said anything about some function systems compiling custom frameworks 'n stuff (just kidding). Thats why I need learning paths not a specific coding practice guide.The most simple question: "What to learn after I finish 'mastering' PHP? Should I use it or implement it with javascript or am I too ambitious?"

res.write spanning multiple functions?

I am trying to display domain searching results from a user-search. The flow of the application is:The user make a search (could be stackoverflow.com).The application returns a result from that search.In the background the application keeps searching for other domains and displays the results when they are ready.I am using Express in Node.js and from what I understand, it would be possible using res.write() and finish it with a res.end(). However, with my current setup I just get a "Write after end" error.I assume it's due to Javascript asynchronous nature, but I am a new developer, so that would just be my guess.This is my code pre-res.write. How would I rewrite it the best possible way, to create a res.write stream?router.get("/new", function(req, res) { //Strip all subdomains - the post var now only contains the domain and TLD. var post = getDomain(req.query.id); //Check if the user inserts a valid TLD. if (!tldExists(post)) { return res.send(JSON.stringify("invalidTld")); } //I want to replace every res.send with res.write after this comment functions.singleDomain(parse(req.query.id).hostname) .then(function(value) { res.send(JSON.stringify(value)); }) .catch(function(error) { res.send(JSON.stringify(error)); }) functions.checkDB(post) //Check if domain has been resolved within the last 24 hours. .then(function(value) { let promise; if(value !== false) { console.log("Domain has been resolved within the last 24 hours"); return res.send(JSON.stringify(value)); } else { promise = functions.lookupDomain(post); } return promise; }) .then(function(value) { res.send(JSON.stringify(value)); }) .catch(function(error) { console.log(error); }) });

Kinda like facebook.My current idea is having both:{"hearts": [james, fred, george]} {"newHearts": [james]}objects in the users mongo database. And every time an item gets added to hearts it also gets added to newHearts. Then when a user acknowledges the "newHeart" i remove the item and the array is empty again?I've never done notifications before so wasn't sure there is a best practice? Bear in mind I also want to add in similar notifications for messaging later. So may be worth considering that. Thank you for any help!

Promise.all() and Readline problem. Need help.

I've been working with NodeJS a lot lately – I'm creating an assistant to help manage Bitbucket repositories, initiate new projects cloning the main template and stuff like that.So, I created a function to get information from the user. You pass the question as a parameter, the function uses readline to get the information and returns a Promise – resolved with the answer and rejected if nothing was typed.Most of the time I need more than just one information, so I'm using Promise.all() with all the questions I need to ask. The problem is: as long as the user answers the first question, the program just stops. I tried using rl.close() everywhere but it just doesn't work. Although it works if I chain the functions like ask(question).then(ask(question).then(ask(question).then...)).On the actual function I'll be handling errors way better than this, but here's an example:function ask(question) { return new Promise((resolve, reject) => { rl.question(question, (answer) => { if (answer.length === 0) reject() resolve(answer) }) }) } Promise.all([ ask('Username:'), ask('Email:'), ask('Client Key:'), ask('Client Secret:') ]).then((data) => { console.log(data); }).catch(() => { console.log("Something got lost."); }) Also, if it helps, I'm asking a simple YES or NO question before this chain – "You need to setup your Bitbucket account first. Do you feel like doing that now? [Y/n]" – But I've already tested it without this question and it still doesn't work.Can anyone tell me what I'm doing wrong?

[Help] How do libraries like material-ui achieve this sort of module pathing?

I am building a React library, and I'm to the point where I want to start figuring out how the developer experience is going to go. I really like how libraries like material-ui and react-bootstrap let you pull directly from a path, rather than deconstructing (though I'm sure this isn't that big of an issue).Pathing in question:import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider'So, I've gone through material-ui's github, and I've gone through their npm module once it is installed and I see essentially how it is happening. They have each individual file/folder in the root of the project. That's cool and all, but I can't seem to find anything in their build/publish process that would dictate that this sort of folder structure should be generated. Does anyone have any ideas on how I could achieve this?

Learning Promises and Reduce, Map Functions Cut My Code In Half

I've been a web developer since I was a teenager, and I started learning node last year to build a cloud-based data platform on GCP. Over the last year I've forced myself to start learning about promises... For some reason, this concept took me a long time to "get".Recently, I've started rebuilding some of my essential functions, and comparing my old code, realized how much promises help.All of my code that requires synchronous data transfer and analysis has been cut in half, and way simplified. I used to have these crazy nested recursive functions with callbacks to set off the next event.Now it's just a few basic chained promises. As if cutting the code in 1/2 wasn't enough, reading it is now 10x easier too. Reduce was pretty critical to getting all my arrays of data to process synchronously, which further simplified things.Anyways, if you have not learned promises, reduce, map functions yet, I highly recommend it!Just the gist of what I'm talking aboutlet myArray = ["beans", "soup", "peanuts", "artichokes"]; myArray.reduce((promise, item) => { return promise.then(() => { return itemsPromise(item); }); }, Promise.resolve()).then(() => { console.log("ALL DONE"); }) let itemsPromise = (item) => { console.log("Item: ", item); return new Promise((resolve, reject) => { setTimeout(() => { resolve(); }, 2000); }); } I'm really excited about this!!

Module somehow not receiving variable

Hi, I have this weather forecast app where the weather is retrieved based on the users location.However, there is this strange behaviour where if I pass in my hard coded ip address to the line where.is('87.92.111.226', function(err, result) { I get the correct result, but if I pass the variable ipAddress, the node-where module fails to find the location details. The strange part is, if I res.send(ipAddress); the ipAddress just before that line, it outputs my ip address, so the ip address should be passed to that line. How come it's failing? Thanks.const express = require('express'); const app = express(); const request = require('request'); const where = require('node-where'); // Callback that ends the process *when* the response is sent const endSuccess = () => process.exit(0); const apiKey = '********************'; let ipAddress; let city; let weatherForcast; let url; app.get('/!/node-weather', function(req, res) { ipAddress = req.connection.remoteAddress; if (ipAddress.substr(0, 7) == "::ffff:") { ipAddress = ipAddress.substr(7) } if (ipAddress) { // Call node-where module method to get location details from ip address //res.send(ipAddress); where.is(ipAddress, function(err, result) { if (result) { //res.send(result); if(result.get('city')){ city = result.get('city'); } else { res.send("City not found"); } url = `http://ift.tt/2pmJPiR; // Call request module method to query the api request(url, function (err, response, body) { if(err){ res.send('Error:', error); } else { let weather = JSON.parse(body); weatherForcast = `It's ${weather.main.temp} degrees in ${weather.name}!`; res.send("Done: " + weatherForcast); } }); } else { res.send(err); } }); } else { res.send("No IP Address found."); } if (res.headersSent) { res.end('Done', endSuccess); } }) app.listen(parseInt(process.env._2038_PORT), function(e) { if (e) { console.error(e); process.exit(1); } console.log(process.env._2038_READY); });

I’ve noticed in my area 90 % of react shops use node for their backend, is this coincidence or does react work better with node on the backend than things like django/other frameworks?

My goals is to get a job in react as a front end developer, noticing so many react shops use node, I have 3 questions.1) does react work better with node given the amount react shops I see using node ?2) since most of you are probably backend developers on this forum, do you think as a front end developer learning some node would benefit me in being a more competitive candidate for a react dev. Since some of you probably work with react devs and know if they interact with node at any level , what’s your opinion?3) as someone completely new to backend , I’ve heard I should start would django first , even if I want to learn node because django has “batteries built in” and it should set up my understanding of backend faster than if i tried to learn node first.Many thanks!!

Best way to store a value that is rapidly updated.

I have always had a super silly idea to have a webpage with a single button that when clicked would update the global value for times the button has been over all time. Storing the value in a database would not be good because of how fast it would have to be updated for everyone clicking the button multiple times per second, so how else could this be achieved. I’m just curious.

Building an app that requires sending browser notifications when client's not connected to site?

I'm trying to build an app that delivers real time information about an event through browser notifications.I thought I'd use socket.io to do this, but the connection closes when a user exits the site. I want to be able to send a notification even when a user isn't connected to the page. I know this is possible, but not sure where or what I'm looking for. Can anyone help?

I am creating a "switch" in nodejs. Please help.

I am creating a "switch" in nodejs. The job of the switch is simple. Client will send it a payload through a post request and this "switch" will send that payload to another server (which will respond asynchronously) by making a post request using request module. Simple stuff.Now the catch here is that the incoming traffic will be HUGE. I have never done such thing on such a scale in past. Just wrote simple nodejs backends for few users. I would be grateful if someone could help me on what are the other things that I need to keep in mind like encryption, encoding? Other things? Any open source project where I can look? Any input is greatly appreciated.

How can I send a JSON object which also has a File object through a POST request?

I posted a StackOverflow question about it.But basically, I have an object like this:const people = { admin: { adminName: 'john', avatar: { img: File } }, moderator: { modName: 'jake', avatar: { img: File } } }; The img property is just a File object. I'm basically trying to send this object to my Node server in a POST request.Here is what I tried:client.jslet formData = new FormData(); formData.append('admin-name', people.admin.adminName); formData.append('admin-avatar', people.admin.avatar.img); formData.append('moderator-name', people.moderator.modName); formData.append('moderator-avatar', people.moderator.avatar.img); fetch('/submit', { method: 'POST', body: formData }) server.jsimport formidable from 'express-formidable'; router.use('/submit', formidable()); router.post('/submit', (req, res) => { console.log(req.files); // This contains the Files objects console.log(req.fields); // This has the rest of the data res.end(); }); Server Output{ 'admin-avatar': File {}, 'moderator-avatar': File {} } { 'admin-name': 'john', 'moderator-name': 'jake' } The problem with this approach is that I have to manually append each field, which isn't really feasible for a larger object. Also, I'm not crazy about the fact that the admin values are not grouped together anymore in the server-side, as well as the moderator values.Is there a better way to do this?

Project/Folder Structure for Node/Express Apps

Hi there,There are lots of good tutorials out there for getting starting with Node and Express, but many of them end when you have a 300-line server.js file that handles a handful of endpoints with minimal middleware.That's obviously unmaintainable long-term, so what sorts of project/folder structure best-practices do you follow? Or, do you know of good documents out there?I'm not talking about monolith/microservices directly, here. This is just about project/folder structure for a developer to stay productive.I see some advocates of the typical MVC separation of concerns, but also have seem some compelling arguments to structure by components and against MVC.What has worked for you? What advice would you give someone starting up a relatively new app?

Nodejs test structure noob question

Hello!I am new to the TDD world. I need to test API endpoints responses and I have some doubts on how to properly structure my tests. In particular, I need to test the HTTP Response code, the Content-Type header and check that the body contains some stuff.I have doubts about where I should do everything in one single it by chaining these tests, or it is better to provide different its for each of these.For instance, I could do this (done here):describe('GET /v1/accounts', () => { it('should return all the accounts', () => { return api.get('/v1/accounts') .expect(200) .expect('Content-Type', 'application/vnd.api+json') .expect(res => { expect(res.body.data).to.be.an('array'); expect(res.body.data[0]).to.be.an('object'); expect(res.body.data[0].type).to.be.equal('account'); expect(res.body.data[0].attributes).to.exist; }); }); }); Or I could do this (which is what I was going for before reading the option above):describe('GET /v1/accounts', () => { it('should return 200 OK', (done) => { api.get('/v1/accounts') .expect(200, done) }); it('should return Content-Type application/vnd.api+json', (done) => { api.get('/v1/accounts') .expect('Content-Type', 'application/vnd.api+json', done) }) // ... and so on }); Both approach work, so which one would you pick and why? Are there alternatives to these approaches?Thanks!

Is NodeJS/Express/Angular the right fit for a community website? Frustrated.

This post may be a bit long/ranty, but I'm feeling (perhaps more than) a little frustrated with my research into NodeJS/frameworks. Maybe this isn't the right place to ask, but I need some input from those more familiar with NodeJS and all the related frameworks to help steer me in the right direction.I did web development for around 10 years (PHP/MySQL/HTML/CSS/JS), until a couple of years ago when I abandoned it to pursue my real passion (game development).Recently tasked with developing a new website for an online community I am part of, I thing it would be a good opportunity to learn newer technologies for web development (especially as PHP drives me nuts now). I've been going back and forth between Ruby on Rails and NodeJS, but I think NodeJS may be a better bet as I'm way more familiar with JS than Ruby.I'll explain the project first. For general visitors (and search engines) it will be a collection of static pages like any typical website. Where it gets involved, is for members - OAuth login, webhook integration with a third party service, multiple member tiers, data exports to various formats, etc. Basically, automation and tools for managing and interacting with the community.My initial thought process after doing some research was to design it as an ExpressJS API backend, with an AngularJS frontend. This made a lot of sense to me, initially. I've managed to find well-documented libraries for handling various aspects, such as Passport for OAuth and a JWT library for detecting user authentication between frontend/backend. However, as I delve deeper, I'm getting frustrated with what seem like the basics.For example, while the Express documentation is really good at explaining the API, I've yet to find a good explanation on how to structure an Express project. Most tutorials just put everything in app.js (we're really still doing this in 2018?) and few have spread things across "component" files but offer no explanation beyond "put this code in x.js". Is there no standard structure? Is MVC just loosely implied in NodeJS frameworks rather than strictly forced like in Rails?Another example is with the Angular frontend/Express backend approach, that SEO will be an issue for all of the static pages. I came across Angular Universal, which should be the solution but also puts so many architectural questions in my head. It's not really needed for the places where Angular would be used (logged in users), yet if I stick to the API based approach it seems like a really big weird caveat-filled workaround for static pages that Express could just render itself. Likewise, if I wanted to have these pages dynamically load by AJAX as well as still function statically, this wouldn't be suitable either. Is there not a better approach?The more I dig the more unsure I get. Almost every tutorial and guide I find is about using NodeJS/Express/Angular to make an SPA (are todo lists the new hello world?), whereas I think what I really want is an "MPA".Overall I think I'm misunderstanding something or falling into the classic "using a hammer to put in a screw" trap. Am I looking at the right toolset here? Are there frameworks other than Angular/Express that would be a better fit? Or are they the right tools but I'm just using them wrong? Should I look at a different architecture entirely?TL;DR - Is a NodeJS/Express/Angular stack the best fit for a community website with a mix of static and dynamic content?
