Using mssql, getting 'RangeError: index out of range'

Advice on "testing" API?

Hello,I've been asked to test a backend API to be ready for a production setting.. Any recommendations on how and what to test? I was thinking I could use mocha and chai and test against the http end points and validate responses..make sure invalid tokens don't work, etc. any thoughts? Just curious about industry standards for backend testing

Can't use ES6 modules in Node v5 ?

I'm working on node app (with node v5.4 installed) and can't use ES6 modules.I have the following error when I run my app:import express from 'express'; ^^^^^^ SyntaxError: Unexpected token import What's wrong ? I thought that Node v4+ supports most ES6 features (well, at least ES6 modules since they are very popular and useful)

Express Controller Unit Testing Question

Hey everybody,I have a function in my controller that I want to test but I'm not sure how to go about doing it.CONTEXT: My application has an api which goes through a router and currently, the post for /api/object/create is mapped to the objectController.create() function withrouter.post(/api/object/create,objectController.create) My controller looks like this: exports.create = function(req,res){ //User will submit an object for creation with req.body.name and req.body.longName var Objects = models.Object; console.log(req.body); Objects.create( {number:req.body.number, name: req.body.name, longName: req.body.longName}) .then(function(result){ res.send(result); }) .catch(function(err){ errorController.databaseError(err,req,res); }) } Now how do I create unit tests for this? I've followed this tutorial which tells me to use Sinon.spy to observe the res.send() and ensure it gets called but that does not work. http://ift.tt/1UAsjjn have seen a lot of tutorials calling for me to test by having the server running and actually sending POST's to the api, but that seems like End-to-end testing and is not what I'm looking for.Any help would be much appreciated :) Thanks!

How to pick up node JS without knowing JavaScript?

I joined a team were I will be a backend Node.js developer. Unfortunately, my mind is wired all with C++, Java, C#_like languages, and almost no exposure to JavaScript.Now there is a whole code base that I am not even familiar with the syntax, terminology, etc! Like, I don't know why in some files (classes??) I seesearch: function search(req, res) { ... } and in another file I seeSomeService.search = function search(context, someID) { ... } I need some neat explanation on how we write classes, where are private and public members, etc. if there are any of such concepts. And anything else that I cannot think of with the "synchronous" language mindset.I have really tried to do my homework and Googled for tutorials on Node.js, but they assume you are familiar with JavaScript, or they go too deep into installing, npm, Express, etc. I really don't have the time to go through JavaScript now :( The project is running and I'm already in!!I want to learn from the code that we already have. But for that, I need to know the very basics, and the syntax, and to fix my mindset!How to do that??? Any magical guide or something? I really appreciate your help and I know you may hate me because I want to learn it the easy way!tl;dr: Coming from OO with no js background, need to know the very basic concepts of Node programmingEdit: grammar

Socket.io Help v2.0

Alrighty, here I am again asking for help. I now understand SocketIO a LOT better. But I have a problem again. When users hit the create button an li should be added to the HTML and removed after 15 minutes. In my index.js file I can't do this because I can't use document, and I don't know how I can do all of this and save it (So that I can refresh the page and the li's are there and are gone only after 15 minutes later). I have tried a lot already, like sending back 2 variables consisting of a title and a URL to the client and adding those in the LI, but that didn't work (probably my fault since i dont know how to properly send multiple variables in one emit, havent found good tutorials on that online) So if somebody knows how i can accomplish this please tell me. If you have any questions just ask :). I am going to bed now so I will be able to reply to all of you tomorrow! Good night :)

Socket.IO Beginner help

Hello guys, I am new to Socket.io and have a problem. I think it's solveable rather easily but I have been struggling with fixing it for the past hour... This is the code: var express = require('express'); var app = express(); var http = require('http').Server(app); var io = require('socket.io')(http);app.use(express.static(__dirname + '/www.csgolobby.com')); app.get('/', function(req, res){ res.sendFile(__dirname + '/index.html'); }); io.on('connection', function(socket){ console.log('a user connected'); }); http.listen(3000, function(){ console.log('listening on *:3000'); }); The problem I am having is that I don't get the message "a user connected" when I connect. I have gotten that part of the code from the Chat Tutorial on Socket.io. I have changed the vars provided there so I could use all my css/js files from my already existing website in the folder http://ift.tt/1JQ2tr7 is appreciated a lot! _^

My comment which provided a fairly damning clarity on how the ChakraCore PR is an embrace, extend, extinguish maneuver by Microsoft was censored, and I was locked out of the thread

http://ift.tt/1Q0DGxc even though I had copy pasted it to the clipboard knowing it would be censored, I accidentally put something else on my clipboard so I don't have the text anymore. It was a very damning explanation of why the PR is quite suspicious and how the fundamental business interests at Microsoft are at odds with open software.But one key point: one of the most enthusiastic commenters on the PR, a 'MrRio', a.k.a. James Hall, is the founder and director of a marketing agency in Britain that has Microsoft as a core client (see their website, his LinkedIn). He came into the thread and urged that the PR be quickly merged. His prose implied that he actually believes the PR to represent both an embrace and extend maneuver by Microsoft. From his exact comments:It literally shims the same API rather than extending it [embrace]...Just land it and see what gives. It's adding so many features [extend] and doesn't break anything else. It can be refined once in and think about different engines later [extinguish].One of the other points I made is that MS in the last couple of years has engaged in other underhanded behavior related to open standards that oppose their business monopolies. There was a fraudulent JavaScript demo and article faking a data leak from WebGL that had mostly taken over the Wikipedia article for WebGL, which coincidentally that FUD was also created by technology-oriented marketing firm from Britain.Anyway Rod Vagg is core to NodeSoure, and Microsoft is a key partner for their company, which means that he is absolutely biased in this case, which is why he repeatedly censored my comment, even though a few people immediately suggested that I had made a valid point.But my prose in that comment was probably the best I have written, which is another reason I think the comment was deleted so quickly.

Socket.io authorization

Hi!I'm going to use OAuth2 to secure my API as well as with my socket.io API. I've looked into it and it seems fairly straightforward (there's an authorization hook for socket.io).My only question is what would be a nice method to allow non-authenticated users to still receive events rather than simply disallowing them access. Authenticated users should be able to receive events as well as emit them. My first thought would be to attach a flag to the socket session 'read-only' or something. Any suggestions?The context is a public chat room, where logged-in users can actually send messages and anonymous users can still read.Thanks

Using ES7 with ExpressJS ?

I recently tried the new Async Await feature and was amazed about how it transformed my old unreadable code in something really beautiful.I used it in a simple Node.js script and used bluebird.promisifyAll(someOldCallbackBasedModule) to transform all my callback based libraries and module in Promises so I could use await on them.Now my question is that if it is possible to use this in Express ? I know there is Koa2 that has it, but I already have an express based backend and want for example to use async await instead of promise.then() in some of my middlewares and keep my other old middlewares as they are.Is this doable ?

I'm trying to get up to speed on all the new web techs. I come from a background similar to LAMP. I've managed to get a few rails apps deployed over the last few years and now I'm trying to figure out nodejs. Specifically... deploying nodejs applications in production.I started working with Google's Web Starter Kit and I understand that this is just the front-end (it spits out some static assets). How do I "pair" this with a server side application in a production environment? Do I need to run two servers?I have some experience with AWS (specifically their elastic beanstalk service), and deploying rails applications. As in rails, we don't typically let rails handle the requests. How does this work for nodejs? Do I still use something like nginx?

Advice wanted for designing App architecture

Hi, I am absolute newbie in Node and JavaScript. I am trying to design a web app and before diving into it, I want to get some opinions for the architecture. Because I learned with a hard lesson that if you don't plan your architecture well, it will fall apart not now but in the future for sure.My app will have basic REST API with usual GET POST PUT etc. It is an API for updating exchange rate of different currencies. Users add currencies to monitor(POST). When it is added, system queries xe.com for the exchange rate and adds currency to user’s table(Mongodb) and show the result. User can update the current exchange rate whenever he sends request to same endpoint(GET). Also there is some sort of cron job or queue system that sends email notification to users per hour according to last update time of currency. Cron job or queue system should allow deleting or updating job if it is not started.For now I am using Express, Mongodb and Jade as template engine. I heard Koa but all the resources I have found mostly based on Express therefore I went with Express. I use request,cheerio and async modules for asynchronous html scrapping.I will really appreciate if you can give me some advice for the architecture or point me to some resources that I can check it out and learn. Thanks.

Common DBs to connect with Socket.io/websockets?

I've been working on a portfolio project with React+Redux and now moving into the backend side of persistence -- I'd like to keep the client in sync with data changes using websockets -- while the choice of DB will also depend on how the data should be organized and retrieved..

Could somebody explain weather my nodejs "makes sense"?

Hey. First time I'm posting here. I'm not new to programming but I am completely new to Node. I was hoping somebody could check out my code and tell me if it makes sense, from a Node stand point. Are my callbacks being used correctly, do the asynchronous methods click, stuff like that.The code is basically to select info from db, convert it to a js object and then convert this object to json, before writing it back to the database.'use strict' var _ = require('lodash'); var async = require('async'); var seneca = require('seneca')({ timeout: 10 * 60 * 1000 }); var config = require('../config/config.js')(); seneca.options(config); seneca.use('postgresql-store'); seneca.ready(function(){ function run(cb){ var eventsEntity = seneca.make$('cd/events'); async.waterfall([ function(done){ eventsEntity.list$({fields:['dates']}, {limit$: 'NULL'}, done); }, function(events, done){ async.eachSeries(events, function(event, done)){ var dates_obj = JSON.parse(eventsEntity); var dates_json = JSON.stringify(dates_obj); eventsEntity = dates_json; event.save$(eventsEntity, done); } } ], cb); } } run(function (err)){ if(err){ console.log('error', err); } console.log("Done"); seneca.close(); };

Back end coding help

Hello everyone, I am currently busy with a website. One feature is that you can fill in a few inputs and hit create to add a div with the input values in them to the HTML. I know that you can add a "live" script for the divs to the HTML, but I don't know how. If someone could help me with Node I would really appreciate it, thanks :)

Redirecting from POST [Express 4]

Hi! In this piece of routes code I'm trying to make a different flash-messages appear depending on user input (correct or wrong pass; if correct -> change current pass, show flash-message).The problem is that I can't redirect from POST. How it can be done? var flash = require('connect-flash'); var User = require('../app/models/user'); app.all('/change-info', function (req, res) { if(req.user.validPassword(req.body.oldPassword)){ User.findOneAndUpdate({'local.password': req.user.local.password}, {'local.password': req.user.generateHash(req.body.newPassword)}, function (err, user) { console.log(user); }); res.redirect('/flash-success'); }else{ res.redirect('/flash-failure'); } res.send(); }); app.get('flash-failure', function (req, res) { req.flash('pass-changed', 'Wrong current password'); res.redirect('/profile'); }); app.get('/flash-success', function (req, res) { req.flash('pass-changed', 'Password successfully changed'); res.redirect('/profile'); }); app.get('/profile', isLoggedIn, function(req, res) { res.render('profile.ejs', { user: req.user, message: req.flash('pass-changed') }); });

Sqlite3 help

Hey gang,I've just working my way through a book called Node Craftsman, and am doing some database stuff at the moment.I've got a test failing at the moment, we add three rows to the db, then send a request to our server (basically just SELECT * FROM table), but the response has an extra line;Expected:{ _items: [ { id: 1, value: 'Aubergine', categoryID: 1 }, { id: 2, value: 'Onion', categoryID: 1 }, { id: 3, value: 'Knife', categoryID: 2 } ] } Actual:{ _items: [ { id: 1, value: 'Aubergine', categoryID: 1 }, { id: 2, value: 'Onion', categoryID: 1 }, { id: 3, value: 'Knife', categoryID: 2 } ], _links: { parent: { href: 'http://localhost:8080/api' } } } So after poring over these two objects for ages expecting me to have misspelled Aubergine, I realise there's an extra object in the actual response.Ok so what's up with _links?Here's what my server looks like: http://ift.tt/1ntzIXc (forgive my spacious formatting, I need all the help I can get to get my head around all the callbacks).Is '_links' some metadata added to the bottom of tables? What's the easiest way to prune it from results?Any help, pointers, directions, links to _links info you guys could provide would be super helpful.Thanks a bunch, thombsaway

Mongoose vs MongoDB native for a Mongo newbie?

Hi everyone, I know this has been already talked through but I would like to have some more opinions about it.Considering I have just started with MongoDB in general and I have done a couple of example projects with both MongoDB and Mongoose, I am having a very hard time to choose whether to use one or the other on my NodeJS projects.Here are the reasons why I would choose MongoDB native:The documentation is (in my opinion) much better organized. It's very easy to find the method you are looking for and every single one has at least one good example that's quite easy to understand.Should be faster (refs: http://ift.tt/1K4OL3r , http://ift.tt/1PM3vRo )Here are the reasons why I would choose Mongoose:Need to define a schema. Not a huge plus in my opinion, but considering my little experience this could be of some help.No need to care about opening and closing of db connections, optimizations and (maybe) security issuesI care a lot about the documentation since it's a daily resource while coding on new stuff. Mongoose docs ( http://ift.tt/1qEPsTa ) and navigation is not very well organized imho, while it's much better over at MongoDB.What do you think? Why would you choose one over the other considering the above premises?Thanks

Why is my module installing devDependencies when used via `npm install`?

I just published a module, pg.promised. It only has one dependency, but multiple devDependencies. I created a new project to make sure it was working.mkdir mtest ; cd mtest npm install pg.promised it was put into node_modules but inside /node_modules/pg.promised, there was another node_modules directory with all of dependencies, dev and regular, were in there. I'm using npm v3.5.3. Is this how it's supposed to work? I thought the tree should be much flatter and the devDeps shouldn't be installed when npm install pg.promised is run.

concierge - a node CLI app to rename and tidy movies [x-post /r/usenet]

I posted this in /r/usenet but thought I might x-post here too. Sorry if it's not appropriate for this sub, please report / remove as necessary.So I made a node CLI app which renames and tidies directories with movies.Some notable features:it seems pretty accurate at identifying moviesits highly configurablenice clean code & has a rad plugin structureworks as a sabnzbd post processing script.I should say I'm an amateur coder.. and have never really contributed much to anything. In addition, I've only done a few tests with concierge myself so it's likely to be buggy as hell, as in “pre alpha”. I'm not looking for fame or fortune here, I'm well aware that this app has a really limited use case in it's current form. Having said that, I know I've wanted something like this for a long time, so I thought I'd publish it just in case anyone else is in fact interested.So you can find Concierge on github. The readme should have instructions to get you up and running.Just to reiterate, I've only tested this on my own debian system, so you probably shouldn't run it on media you'd be upset if you lost.I guess I'm looking for two things at this time.. Firstly, I'd love for you to clone the repo and have a go at running it.. I'm sure there will be problems, I just need to know what they are! If you do run into anything, run with “-logLevel debug” and create an issue or report here or whatever.Secondly, I need to know if there's actually any interest in an app like this.. if so, are there any features you'd like to see?

Trouble with installation on Mint 17/Ubuntu 14.04 in VirtualBox. Typing "node" and anything else in console will just return system command prompt.

I'm trying to just get Node up and running.I installed with: sudo apt-get install node and it does kick down to the next line so it kinda works but I do not get the node prompt, just the system prompt. Typing in node -v does the same, just kicks down a line and gives me the system prompt. Same thing happens when I try running a hello-world.js file.Before installation, typing "node" would tell me the command is unrecognized so the installation is doing something.I tried rebooting after install just in case that was the issue.According to SO, there is no error log. How can I troubleshoot what is wrong with the install? Has anyone run into this before?

Quick and dirty learning resources?

Any one have some recommendations for learning node quickly? I did the "Learn Python the Hard Way" thing not too long ago and that was great. I've been given a project at work that is over my head though and I need to figure out how javascript/node works.Some more info on the situation: I only just started seriously writing code a little less than a year ago (all self-taught), I have never written a line of javascript, know next to nothing about node, and I only just heard of gulp a few days ago. I need to tweak some gulp script I was given so one of the bosses can more easily deploy changes to a remote server. They want this done asap.If this sounds like a crappy situation to you, you would be correct.

Node ORMs and Geo-Spatial Data?

I'm relatively new to node and I'm having a hard time finding packages that might be able to assist me with the geo spatial app I'm making.I have a need to store Geometry in a PostgreSQL/PostGIS database - Points, Polygons, Multipolygons, etc. I have not been able to find an ORM that gracefully, or at all, handles geometry. From what I see from Googling, the few example projects that say they interface with PostGIS drop into the raw SQL query of Knex and write raw SQL into the databse. This isn't an option for me.== What I've looked at ==Bookshelf.js - No out of the box support for Geometry. I could install the bookshelf-json-columns specify the geometry columns as JSON and store the shapes as GeoJSON maybe. This would be more of a work around than anything. I'm also wary of how new this plugin is and what kind of support it would have in the future.Sequelize.js - The official documentation doesn't mention anything about supporting geometry but then the several GitHub pages make mentions that the changelog shows that they added Geometry support for postgres in 3.4.0. I popped into their IRC for some help but didn't make much headway. The fact that there's a disconnect between the documentation and what it supports makes me uncomfortable. Since I'm new I would hope to see some documentation to get me to starting point in how to implement the Models appropriately for geometry.Has anyone encountered a need for Geometry with PostGIS in Node before? Does anyone have a suggestion for a good ORM that you might be able to point me ?

Where to place database config/functions in Express?

Hello! I'm pretty new to Node.js and I've started developing a webapp in the Express framework which includes a classic user-login. I want to grab the details through a POST request, and use "router.post()" to validate the user with my database.However, I am a bit unsure of what the conventions are, regarding database-related files. I've made a new file called 'database.js' which has the connection info, and a function called validateUser(), which accepts two parameters - the username and login. I've exported the function to my router.js. In the function's callback, i want to do a "response.send()". But how can I do that when the 'response' is in my router.js? Maybe add 'response' as a parameter in the function.Anyways, do you guys have your database config, functions & router (with GET/POST handlers) all in the same file? Or do you seperate them? Hope I made sense.. :)

Is there any alternative to hunter-gatherer - a parallel rest client?

So I basically use hunter-gatherer (http://ift.tt/1RVljzU) with one of my projects and was wondering if any alternatives exists.Basically hunter-gatherer is a parallel rest client that can handle paging of API results on it's own.Here is it's own description to be more clear;It's ideally suited to the types of calls you see via APIs. Here's one example from the Etsy API (http://ift.tt/1UdNqrn) that you need to make if you want to gather all of a users' active listings: http://ift.tt/1UdNp70 http://ift.tt/1UdNpng http://ift.tt/1UdNqrt http://ift.tt/1UdNpnk http://ift.tt/1RVlmf4 http://ift.tt/1UdNpnm Traditionally, you'd loop through each call, process the results of that call, and then call the next offset, process, ad nauseum. Not only is this super inefficient, it's slow and a pain in the ass to re-code all the time. Especially when this pattern occurs in many APIs, and all that changes between them for the most part are the URL and how you process the results. So let's abstract out everything else! And lastly, with HunterGatherer each of these calls happen simultaneously, up to the maximum number of simultaneous connections allowed based on the remote API terms of usage. Non-blocking FTW! I'm looking for an alternative because the library is out of date (http://ift.tt/1UdNpno) and not updated since 4 years.

So, I'm building a simple API with ExpressJS and a MySQL database, and using Sequelize as an ORM.My question is how do you define the models (eg. User model) in a separate file and folder ? Like having a folder with all the models only. Since to define a sequelize model you have to first create a new instance and stuff like: var sequelize = new Sequelize('database', 'username', 'password', {});

SocketIO: Suggestions on clean way to add events to every client?

Hi there, I have a basic chat/video app that connects the user through WebRTC. Right now I handle the majority of the socketio code through the main app.js file, I'd like to pull the files out to make them testable and improve readability.I was thinking about doing something likelet MyClient = require('myclient') io.on('connection', function(socket){ MyClient(socket.client); Then inside 'myclient' I'd have an object of functions mapped to their event names.var events = { 'join':function(), 'leave':function(), } And one function that would do a for in loopfor(key in events){ client.on(key, events[key]); Is there a better way to do this, or a standard way?

Request.js delay breaks script

Script: http://ift.tt/1P41rYL with the node this week and tried to make a script that checks for 404 images on a website. I've got it all set up and decided to use request.js - The script didn't work and while debugging I noticed that there's some sort of delay on the request function; the loop runs, and then when it's done looping it starts to get the responses etc. This means that I'm constantly trying to do image.push(url) with 'var i' set to 39000 because of the delay. I hope I was able to explain my issue, is there a way around this?

How to optimize Sequelize (pg) + Node;

Hello folks,My question is: if I'm reating something like blog, social network or just some portal how should I handle with sql queryfing?Example #1:User is checking his statisitc and sees: Messages: 234 Games played: 23Now, every time user is reloading /stats page, query is executed. Why? Because after user send a msg or play a game his counter will increase +1. So SELECT count(*) from MESSAGES where id_from = user.id runs on whole big table to fill template engine "messages" variable.Example #2:user is checking out blog. Every refresh (F5) big query is executed to fill template engine with areticle short description, image, date, author etc.Question:How I should prevent such DB overload if 1k users will just check out blog and some users will spam F5? It will just kill my VPS... I'm using Sequelize on PostgreSQL if that means.

I already have code for listening to a mailbox and then forwarding as needed but just need an email server. I really don't want to host the email server myself as I'm not comfortable with email server setup so I need a hosted solution. Initially it'll just be for development/testing but eventually I'll need one for production. I'm ok with switch hosts for a more economical one when it comes time for production.Anyone have any recommendations?I'm sure this isn't quite the right subreddit, so you're welcome to direct me to right subreddit.

Having trouble deciding on stack for next project

Basically, I am building a social media type app for fun, and as a learning experience, but i am having trouble deciding on what tools to use.I have experimented with bower, npm, browserify, gulp, grunt, webpack, express.js, koa.js, sails, react, meteor.js, riot.js, and now vue.js, and holy fuck am i overwhelmed. I really like the idea of javascript fullstack.i have ruled out vue.js, because of the lack of server side rendering, and I am leaning towards using riot.js, because tbh i dislike react.js. I am leaning towards using sails, because i come from a rails background, but I would like to build a SPA on top of a REST api, with server side rendering. I dislike the idea of using mongo, so I will use postgres with some stuff being json.Does this sound sane? what is your idea stack for node.js? Does sails + riot.js + postgres seem like a reasonable stack?

too much async

before i get too far into this, here's the situation... i've inherited a server app and the job to add a feature. i'm pretty limited in how much i can change the architecture. client connects to server, makes its request, and expects a final response. the server takes the request and now has to connect to another server and start a process, which runs asynchronously, but can call back to my server when its done with the results. which somehow have to get back to the original process so they can be sent back to the client. i hope that makes sense. i'm not expecting any miracles, but some ideas on how to maybe approach this would be greatly appreciated.

JS/Jade: how to update a page based on a dropdown?

Note up front that I am just learning JS and this might be better in the JS subreddit, but I think there's a node/Jade-specific aspect so I thought I would start here. But there might be an obvious answer that I just don't know the terminology well enough to Google for.I have a page that looks like the following:form#formSetup (name="league_details",method="post",action="/addleaguedetails") select(name='league_select') each league in leagues option(value=league.id) #{league.name} option(value="-1") New input#inputName(type="text", placeholder="name", name="name", required="true") What I would like would be to have the input prefill with the name of the league that has been selected. One idea I had is that instead of passing in an array of leagues, I could pass in a map of index to league and use that index for the option value instead of the league id, so that i could more easily reference the selected league based on the selected option value, but I'm not sure if that's the best way or really how to make the input fields update when the select happens. Do I use a JS function or is there something Jade-specific for this?

Complex Authorisation in a node app

Hey, Let me just prefix this post in saying I am by no means an expert in node. I have just been playing around and built a couple toys and I am now building my first app that I am hoping to put into production and I would love some advice from more experienced programmers.So I am building an app. The DB I am using is mongo with mongoose as my ORM and my framework is hapijs.I have a pretty confusing authorisation structure that I need to implement which I am not sure if I can do with existing modules.So let's set out my structure.Users are part of "teams" within each team they have a role this role grants them specific privileges that allows them to access certain routes and carry out actions on data. For instance if they are an admin they can modify other users profiles and the team itself.A single user can be part of multiple teams and have a different role on each team.Then there are resources which are user created. A user can grant access to this resource to a role. This will allow all users within any teams that the creator is part of who are assigned that role to access the data, but only when they have that team as their "active one". Users can then also create finer grained access where they can grant a single user access to that resource.Now please let me know if I haven't explained myself properly. I understand it's pretty complex and confusing.The approach I am looking at to handle this is similar to how AWS handles IAM authorisation. Each resource has a document that specifies the specific actions roles or users can perform and the server checks this document on every request. There will then be a general policy document for the roles as a whole on actions they can perform.If I am going about this completely the wrong way please tell me. Thanks.

Help Needed: how are Express routes (REST)used to save to Mongo Databases?

I'm a bit new to this, but I'm afraid I'm missing a piece of information and hoping you can help me understand.Specifically, I'm working through the thinkster.io MEAN tutorial on the REST Routes portion. http://ift.tt/1OYaN8d works according to the tutorial, but I'm not understanding exactly how the second to last snippet works.router.post('/posts/:post/comments' function(req,res,next) { var comment = new Comment(req.body); comment.post = req.post; comment.save(function(err,comment) { if (err) {return next(err); } req.post.comments.push(comments); req.post.save(function(err, post) { if (err) {return next(err); } res.json(comment); }) }); }) Here's my understanding.A POST method on the URL /posts/:post/comments is encounteredA new comment variable is created from the Comment prototypeThe comment.post object is set to the req.post value (Help needed: is this thanks to express and the URL parameters?)comment has a "save" method which is handed a function.this function brings in the (express or mongo) error and the "comment" (from the POST method?)this function errors out and quits if "err" existsthe function pushes the parameter "comment" onto the comments array of the req.post object (Question: is this in the browser memory?)req.post.save is ran, which pushes the data in memory to mongo (right?), bringing any errors and the post (Help needed: Why are we saving the post and not the comment)this function will quit if "err" existsres.json(comment) (Help needed: This part is the most puzzling. So the response already has a JSON method that hands data to the server?Seriously, thank you for your help!TL;DR; Don't understand how express uses REST to save to mongo. Extra reading material is appreciated.

I mostly build sites using Django which was originally developed for news organization's publishing needs, however with the advent of Node.js and API's I am considering an API centered approach, my concern is SEO.SEO is very important for news organizations and e-commerce (my other primary clients) and an API centered approach with separation of concerns involves a client app that probably uses javascript, this is all well and good, but we all know js frameworks and SEO require a lot of additional work e.g. (Phantom.js, Selenium, etc..)

Question regarding NodeJS multiple apps on AWS, do I store it on the root partition or on a mounted second volume?

Hey all, I'm just wondering if it's worth adding a second EBS volume to our instances to store the NodeJS application data, as opposed to storing it under /opt/$appname on the root partition.It makes sense to me to decouple the application from the OS in a scalable environment for flexibility but on the other side of the argument there is 'simplicity' by storing the app on the root partition.I know this is quite trivial but I'm just wondering if the benefits of another EBS volume are worth the trouble.This is a scalable NodeJS app running on Ubuntu 14.04.Thanks

Non blocking image processing on a server?

Waiting for a query to return?

I'm working on my first project with node.js and Jade. I have a router.post target that does some parsing of input, then does a MySQL query, then based on the result of that it might do a HTTP request and some parsing of the page content, and finally depending on the results of all of those it should decide what page to forward to.However, it looks like what's happening is that it starts the database query but doesn't wait for a response before continuing, so even if the DB/HTTP work would cause it to go to a page other than the default, it goes to the default and then completes the DB/HTTP work. I can see in my console logs something like:begin text parsing redirect to default GET /finalpage begin db query db data received begin http request http data received http data parse result What can I do to make the processing run serially, or is there some other way I should be architecting this?

My new template language, for emmet one page apps

Hello from /r/javascript!I just published the second version of my weekend project emmetp, a emmet template language.I haven't thoroughly tested this version and could use a few testers, also would like some criticisms, optimizations and code review if anyone wants to. I'm using it as a code sample while applying, but tbh I think it's too regex-heavy.src: http://ift.tt/233XOYJ: http://ift.tt/1Kh1rz3: npm install emmetp -gWhat does it do? Its a template language based on the emmet sublime plugin. And you can inline JS or es6 now.Why? Mostly for one-page apps and code golf, or for mocking up a prototype/quick hack. When the project grows just move the JS out and push TAB to expand the emmet, right? right.Example:! #app span{hello world} button.btn1+button.btn2 #footer>div>span>label{or just one line} script& console.log('inline js') - script&coffee: console.log "or coffeescript/babel" - That should output a fully functional HTML file with working javascript (and coffeescript compiled js).If you want to try it out you can npm install emmetp -g.

How to thunkify Promises with Bookshelf?

Alright, the title may be a bit vague, but I couldn't come up with the right keywords to find this using Google. I am writing a piece of software where I use yield whenever necessary (well, not necessarily, but in this case it makes my code much easier to read and much cleaner). Anyway, libraries that don't support it, I thunkify by using thunkify (http://ift.tt/1QF0V3i). So far, so good.But Bookshelf has a different approach, because the functions are 'chained'. For example, say we have:User.where('id', 1).fetch({withRelated: ['posts.tags']}).then(function(user) {How do we thunkify this (if possible at all)? Do we use thunkify(User.where.fetch.then)?

Help with long running commandline node process

Hey there, I'm looking to monitor for a few processing events, like SIGKILL, and respond to them. The application does nothing else. So I have something like:process.on('SIGINT', function(){//stuff}; process.on('SIGKILL', function(){//stuff}; And I want the process to continue running. I've seen a few posibilities like:setInterval(function(){}, Math.POSITIVE_INFINITY); require('net').createServer().listen(); // Grabs random port? Is there a preferred way for me to do this? This is intended to be in a docker container and to inform a clustering tool that the host is going down via an api call.

How to require modules without specifying a path

I use browserify for the front-end which means that I sometimes share packages between the server and front-end. This means that my "Universal JS" libraries are separate from the rest of the code.Here's what my dir looks like:/lib //for universal /web //for front-end /server //for server now, whenever I'm deep in the front-end, going back to /lib is a pain. The requires pretty much look like ../../../lib/numberLib. Same with the server.Is there any way to specify custom aliased libraries so that I could just do numberLib and it'd require that specific library?

Webworkers and Atom

Hello,I've been using PhpStorm and WebStorm for the last two years, but mostly PhpStorm. I decided to move to Atom and started using a package called atom-ternjs, but it's very slow (older versions work fast enough but newer versions are very slow) and laggy. http://ift.tt/1mWXQRd's a warning, though, but I need to be able to get autocompletion for every package I added to my project, like asyc, bookshelfjs, cheerio, request, etc."loadEagerly is expensive. Do not add paths like node_modules."I'm not sure whether it's possible or not, but here's an idea. As far as I understand, this module works dynamically and it's the main reason it gets slow if there are lots of folders to scan.Would it possible to create a module (or modify this module) to make it work in a way that it creates its autocomplete index for every X minutes (or manually) so suggestions can be fetched from a static file and performance will be higher? That's my guess, though.If it is possible to achieve that, what would be the roadmap I should follow?I'm not very good at Node.js, but I'd like to solve that problem because I want to continue using Atom.

How should I install and use multiple versions of Node on the same production machine? Is it a dumb idea?

I know about n,nave and npm but I think that those are intended for development/testing.Our requirement is that we be able to have more than one version of Node running on a production machine. For instance, I might want an Express app running on Node 4. Also a Koa app running on Node 5. Also a HapiJS API running on Node 6.I don't know that nvm doesn't do this, but since it's a shell script my intuition says it won't. Same for nave and n. Am I wrong?Also, if this is an awful idea feel free to say so.Docker is not an option. Long story. It may be available in the future.I posted this on SO too but I suspect it will be closed for being opinion based.

I'm working with a node application using socket.io and express server. It's just a simple chat application that I am trying to learn these languages and framework with.

I am doing it different, by putting the jquery in a separate file. Can I use socket.io in an external jQuery file? Like will this work:var socket = socket.io();socket.emit("some function", value, function(data)Because I can get it to work internally with the HTML file, but once I separate it, it stops working..but I dont know if this is because I am doing it wrong or if it will not work that way..Anyone have any experience with this? And I do have it in a 'public' folder with the css and jquery, and that works with node when I run the app. It is just when I try to use socket.io it stops working.Thank you for any help, I am still learning.

What architetture/framework for a management (realtime) game?

We are a young company that would develop a "management" sport game like Football Manager but on the web.We are looking for what software/architecture or framework use for game development. Actually we are considering only 2 alternatives:The MEAN Stack (but with SQL instead MongoDB)Meteor JSThe option 1:Advantages: Yes it is "more standard" option, we have some experience with angularJS for client frontend and ExpressJS for REST API on server with Sequelize and MySQL that's good for structured data.Disadvantages In our experience the development is more expensive and long becouse we need to duplicate and rewrite the "models" on client and server side and maintain these aligned. Another break point: what about realtime?The option 2Advantages: It is more actractive for us becouse Meteor seems to be better for real-time applications, for example games. The development should be more fast becouse we can use the same query language to fetch data on server and client without write or rewrite code.Disadvantages We never worked with Meteor and we should learn it. In addition Meteor does not support officially MySQL actually but we have a lot of structured data (players, teams etc) stored in a sql database. We have not a good experience with Mongo becouse of this we didn't think to an hybrid approac, but we are looking for an alternative like RethinkDB.The question is: what architecture/tecnologies would you use to obtain the best result in less time?
