ES6 Store events differ between browser and server?

I am using the following as a basis for learning the basics: http://ift.tt/21q4xLK am not using their authentication, and auth is not an issue. The problem I am having is events right now.I am using their BaseStore, and LoginStore (with modifications to remove their jwt items).I've used console.log(this) to compare the LoginStore on the server and in the browser and have found that the server version only contains one event, assigned to it in the constructor, while the browser version says it has two... the one added in the constructor, and the one added to it within the AuthenticatedComponent.jsx file.The only event that fires when CHANGE is emitted is the listener set up in the constructor. I'm assuming that I have two instances of this class, but only one is being called. I've also confirmed that I am only importing the LoginStore once.

How can I structure this?

Hey,I ran into some issues while creating a simple web scraper.Here's the deal.Fetch 100 pages in parallel.Get page ID of each urlAdd person name and id to the database (person ID will be the same with page ID)Each person has one, two or three professions. Fetch these profession names' from pages, add them into database if they don't exist and add these to the pivot table.Each person has at least one photo, fetch those too and add it to the pivot table.What would be the fastest way to achieve this? I'm kinda new into promises, callbacks, requests and everything.

When is it expected to perform an operation sync/async?

I've been about a week trying to figure out how to do a callback that reads a file and returns the contents of the file to a variable that's available to the rest of the program. I figured that it's a "learning project" so I may as well get used to callbacks and later I'll delve into promises. I mean the exercise was more about recognizing when to do async vs sync.So Today I Learned that data inside a callback is unavailable to anything outside it... Ever. You can bring parameters into the callback function and do some work on it in there, but you're can't bring the result back out and put it, say, in a global variable. (if this is a wrong answer, please share.)Further I realized..."Oh... Duh... I don't necessarily want to be doing anything with the contents of the file before it's completely loaded, so I may as well use fs.readfile synchronously."What would be a good example of when it's best to do something sync/async?

How do you create JSON Schemas?

JSON Schemas are definitely helpful in many cases. Many people realize that, but are too lazy (me! me!) to create and maintain them. To create your first schema you can just take your JSON and go to http://jsonschema.net/ , generate it and tweak by hand, but how to maintain it later?My questions are:Do you create everything by hand?Do you have some editor with syntax checking? (which editor and which plugin do you use?)Is you schema really always up-to-date?Do you use your schema for automated testing, building a documentation or both? (or something more?)

Would you help me selecting what to try next? (Vagrant, RAML/Swagger, Babel/Typescript)

I’m going to start a new low-priority project, and I want to try some technologies I’m not using right now.But…well…there’s TONS of new things to try! Yesterday I was hunting info to make a list of what I may like to try, and were overwhelmed by the size of the list I ended with.Could you help me with some doubts about them, and how to assemble the puzzle? First of all, I’m having trouble teaching some of my team members because of the differences in software/hardware between what I use, and what they use. Because they are always having strange situations with they editors, node versions, saying that in their computers the last commit doesn’t work, or that in theirs it did!I’m so sick of this situation.And then I read about Vagrant. Do you recommend me this way to try to solve our problem?Right now I’m working with node on my system, and I don’t understand for sure how to work with vagrant on my server. The code I edit is in a folder of my computer, I test it…and then I commit the changes to our git.How is the workflow with Vagrant? I need to have the code in the vagrant VM, having mounted the server as a folder i my system, and then try it with a terminal from ssh? Or there is a better way? And I’ll lose the commodity to refresh my browser automatically after changes, isn’t it?BTW, I’m working with VSC under Mac, right now. For this API, I want to try RAML or Swagger…but can’t decide between them.The two of them looks great! Swagger have a lot of community projects on GitHub…but RAML have great companies behind (and being younger, it's normal to have less projects, isn't it?)And I want to secure it with JWT: Swagger do no supports JWT right now, isn’t it? And, finally, Babel and/or Typescript. I would like to try the new options of ES2015, and then Babel…...but Typescript looks great, and I really like the the idea of trying before Angular 2 arrives.I feel like having the two of them at the same time will be overkill. And I’m having a hard time deciding between them the one to try first (I don’t know how much time will pass until the next opportunity to try new things) I know this is one hell of a wall of text, but I don’t know where I could ask about it better than here at reddit :) I had bad experiences at other sites, specially StackOverflow, that I’ll just say that aren’t as friendly as reddit.

Help! I think I'm having problems with variable scope.

I wrote a "route manager" file for my application. It takes in a routes.json file, and registers the routes in Express, based on whether they use a view or a custom JavaScript file in routes/. Furthermore, if it uses a Jade view, it adds in some variables: if the JSON contains "variables": { "foo": ":bar" }, it adds the variable foo with value req.params["bar"].My problem is that this only works once. For instance, suppose that the Jade view is p=foo, and that the route is /:foo/details:The first time I request /2/details, the page shows "2".From the second time on, whenever I request eg. /5/details it still shows "2".In fact, using debug statements, it turns out that the first time my route generator has options == {"foo": ":bar"}, but the subsequent times it has options == {"foo": "2"}.Any idea of how to fix this? Or perhaps libraries that already accomplish what I'm trying to do?Here is a minimal example of the algorithm in question.

Regarding mdns on node.js with socket.io

I am trying to build a socket.io service that clients can discover servers over mdns. I kind of got some of it nailed down, but I can't figure out how to make the mdns browser part working. Ideally, clients would discover servers on their own and connect to it with socket.io-client.// server.js var mdns = require('mdns'); var http = require('http'); var io = require('socket.io'); var ad = mdns.createAdvertisement(mdns.tcp('http'), 8000); ad.start(); var server = http.createServer(); var socket = io(http); server.listen(8000); Now the client side is where it gets complicated for me:// client.js var mdns = require('mdns'); var io = require('socket.io-client'); var browse = mdns.createBrowser(mdns.tcp('http')); browse.on('serviceUp', function (service) { var socket = io.connect('http://' + service.host + ':' + service.port); // this will get lots of "service" objects for every interface (I have multiple network interfaces). Which I only need one socket.io connection. How do I maintain 1 connection and forget the others? }); browse.start(); Client.js idea 1:// initialize socket variable outside of listener. var socket; browse.on('serviceUp', function (service) { if (socket === undefined) { socket = io.connect('http://' + service.host + ':' + service.port); // this only assigns "socket" variable once, which is kind of good. } }); // This, however, obviously does not work. (no method 'on' for undefined) socket.on('event', function (data) { // do stuff with data. }); Client.js idea 2: undefined

Directory structure of Node project & where to put socket listeners/actions on server side

New to Node. Started a new project with npm using express, jade and added socket.ioNPM created a directory structure as such:/project|- bin|----www <- this is the main start file with server in it|- node_modules|- public|- routes|---- index.js|- views|---- index.jadeapp.js <-- routes to /routes dir filesNow I've more or less figures out the flow and where what goes. However, in including socket.io, I'm not fully appreciating where a few things should go conceptually, nor how data gets passed around with require()So www instantiates the server, requires app.js, which requires the files in /routes (index.js) which routes to the appropriate jade file.So two questions: 1) Where logically should I place my socket.io server-side listeners? Assuming there will be a io.on('connection'..., this should probably go in the www (server) file, but where should my io.on('whatever message'... listeners go? It would make sense that I put them where they'll logically be listening to the sockets from the respective routed files (either app.js or index.js?). Which leads into my second question: 2) To instantiate socket.io, I need to use this code: var io = require('socket.io').listen(server); Where server is now defined in my www file. Suppose I want to define this io in another file, say app.js, how do I pass the 'server' variable up to app.js which is imported with require() into www?Thanks.

When working on the server side of a website with node.js do you actually work with a DOM or is it just more of the same php-style templating: find and replace strings, concatenate strings, echo variables in the midst of html, etc?

In the past I've tried using PHP's DOM features to build layouts instead of the typical soup of php+html or find/replace placeholders in an html template file. But it always seemed to take longer and I'd read many posts saying php's DOM stuff is a memory hog.My use case is not a massive complex application that someone is paying money for. I'm just interested in using node to do quick and easy and simple things that I would normally use php for. And since I use php to generate web pages. I think I'd prefer to just use JS with node and utilize the DOM instead of a bunch of string manipulation, if it is actually wise to do so with node.

Questions About Cache and React in Node.JS

As I move forward learning Node and the technologies surrounding it, I am becoming more and more lost regarding what to do "next."I plan to create a very basic social network simply for the purpose of learning the technologies involved in creating something such as this.Most Recent SiteMy most recent site is fairly simplistic. The common pattern is a user visits the route, Node uses MySQL to draw data from the database [1]. The data drawn out is inserted into a Jade template [2] and the Jade template is rendered and sent back to the client. This pattern can be seen at http://ift.tt/1Nrdpgb the user wants to submit an issue, the page must be refreshed [3]. I have no done anything with dynamic reloading or AJAX.The IssueThis is where the problem comes in. I could create a simplistic social network using the same method as described above, but I know there are better ways to create sites such as these and I am having trouble choosing which path to take going forward.[1] Recently I have heard about caching on the server side, though I know close to nothing about it. Instead of drawing from the database I would like to use a cache of some sort, and if it is not in the cache, then draw from the database and possibly add it to the cache. I do not know where to get started learning and do not know if the patterns I am thinking about are idiomatic. Is cache like this just on the server side or is there a similar pattern for use on the client side?[2] Should I be using something more than this to allow for dynamic UIs (such as a simplistic chat in my next site)? I have heard a lot about React paired with Flux and this seems like a good choice. Are there any good tutorials for React and Flux and pairing it with Node? Should I render on the client or the server, and what even is rendering on the server if React is a front-end tool?[3] This issue also melds with the previous. Do I use AJAX or socket.io or something else? Does this integrate with the Flux architecture?TLDR: I have learned the "basics" of Node, Passport, MySQL, Express, etc and have no clue where to go "next." "Next" seems like a step off a huge cliff and I have no idea where to startAny tips, advice, patterns, resources, things to google, etc, are appreciated. Thank you all!

having a problem with fs.readfile in nwjs.

I'm embarrassed to shit to even be asking about this, it's about as dog-ass simple kindergarten coder as you can get.I want to open a file into a container. Array, object, I don't care. But right now it's in a 2d array.http://ift.tt/1MPsVwI It probably won't run there, as it's the part of a nwjs bit I'm working on.in the app, I've successfully read the file and parsed it. Then I split it to lines. Then split the lines to fields (tab delimited + empties).however, every example I can find gives the syntax of fs.readfile then proceeds to do nothing but console.log the data and forget it. They do nothing practical with the data.My problem is how do I actually use that data? I've read the file, and put it in containers, and it logs fine when inside the scope of the fs.readfile action. But the data doesn't survive the destruction of the fs.readfile scope.In that fiddle, lines 27-31 are undefined. when I put them inside of the fs.readfile(), they show the expected data but the return doesn't work.How do I get the data out?

Understanding parameters to anonymous callback functions

Reddit,Getting up the curve on Node.js and trying wrap my head around anonymous callback functions. I understand conceptually how they work and when to use them, but not syntactically.I'm going to use snippets of the default chat app at Cloud9 which I'm trying to understand.My question is - how do you know the # and order of parameters to include in an anonymous callback function for the parent function?For example:messages.forEach(function (data) { socket.emit('message', data); }); It seems to me here that the '.forEach' passes each item of the array as 'data' into our anon callback fn, and then our anonymous function does something with 'data'. Why is there only one parameter to our anonymous function?If I look at MDN (http://ift.tt/15Q6Ehi) for a description of forEach, it seems that the callback should have three parameters (currentValue, index, array). So why does this code snippet only need one? If the answer is 'you didn't need nor include the second two so they were ignored', then why does this snippet of code note work:messages.forEach(function (data,index) { socket.emit('message', index); }); Similarly, the snippet below as part of socket.io: socket.get('name', function (err, name) { var data = { name: name, text: text }; Is it correct if I say: socket waits around until it ".get"s something, and if that something is a 'name', it takes that something and passes it to the anonymous function which has parameters 'err' and 'name'. How did we know to make our anonymous function have two parameters and that the first will be the error returned (if any) and the second will be the value of the something (in this case, the name)? Is there documentation somewhere for socket.get which states its anonymous callback function should always have these two parameters? If that's the case, I'm having trouble finding it.I guess my overarching question is that, as I read more code that others have written, anonymous callback functions seemingly have an arbitrary number of parameters, with seemingly random names and orders. For example, why not (name, err) in the above... why is err first?Thanks in advance.

To commit or not commit NPM deps?

My company is pushing me to start committing our NPM deps to our project's git repo. I strongly dislike this idea for many reasons but there's one point I can't argue:While we can control which specific versions we list as dependencies, those libraries can still be generic as to the versions they depend on. They see no possible way for us to guarantee that everyone has the exact same version of every library, all the way down the tree.Apparently some build failed because of an issue with a new minor version of a deep dependency.Is there any solution to this? Committing our deps feels dirty.

What are the pros and cons of this sort of API architecture?

I have an API that I would like to create using Express. It will contain a couple of layers: authentication, cache, database access.I want to make the most out of middleware and decouple my code with something along the lines of:app.get('/product/:id', authMiddleware, cacheMiddleware, productController.getProduct); Where the cacheMiddleware will return the data from cache or call the next middleware if there is a cache miss. I feel this will make unit testing each component a lot easier. Is this a common pattern? And what are some cons of this pattern?

Help with Process.stdin Event Listening

Hello, I have limited knowledge on coding with node.js, and am wondering if it is possible to "listen for nothing"... I am not sure how else to put it. I will explain my situation- So right now I am trying to program the AR2 Drone with the node.js library. I have listener code set up to listen for continuous keypresses of WASD, moving the drone accordingly (used the following: http://ift.tt/1jeSXRh Response from Peter Lyon using keypress module) However, I cannot figure out how to do the following: when the keys are released/nothing is being pressed, the drone stays in a hovering state. My janky infinite while loops did not work, and right now I can only make it that you press a key and then it hovers. Is it possible to set a new listener that listens for.. no events I guess? I mean -> if no key pressed, drone stay hovering. Am I missing any function that could easily simplify this? If necessary, I post my code of the keypress listener I set up, but its a bit long

Node.js beginner: Help creating an application that allows a User to download a +50GB Feed

I have been tasked with building a Node.js application that allows Users to download our complete data feed, which is approx. 50GB and is usually downloaded through curl, however they may test the calls in their browser (by specifying a limit). The data currently sits inside of a MySQL database, therefore I am using the node-mysql package. As soon as I make a request to the database and get 1 row, I write the data to the response.The Node application is running on a machine with 2 cores, 4GB RAM and 10GB of disk space. However, everytime I try to download the feed, the amount of Memory hikes up (monitored through pm2) and I get a curl: (18) error (A file transfer was shorter or larger than expected.). I've tried setting the header for Chunked Transfer Encoding.Can anyone share any light as to why I'm facing this problem? I'm using Node with Express to easily fulfil requests through the browser.Thanks in advance.

Can you make `require` itself an ES7 Async function?

I'm using ES7 Async/await Babel and it seems I have to do everything in an async function if I have to use awaitmain.jsvar fnA = require('./a.js'); async function main(){ var val = await fnA(); // do something with val } a.jsmodule.exports = async function fnA(){ return await somePromise(); } Wouldn't it be much better to have something like this:main.jsvar val = await require('./a.js') // do something with val a.jsmodule.exports = await somePromise(); I tried to write a require patch so that it can encapsulate the contents of the new file in an async function.__require = require; require = function require_async_patch() { var args = arguments; async function async_require_patch() { return __require(...args); } var prom = async_require_patch(); // prom: Promise { // _bitField: 33554432, // _fulfillmentHandler0: undefined, // _rejectionHandler0: 1, // <- this seems to be module.exports // _promise0: undefined, // _receiver0: undefined } return prom._rejectionHandler0 // todo: await prom } I haven't completely thought it through but even before I tried to go forward with this, it turns out Babel doesn't like await unless its inside an async function. It doesn't care if the parent require is patched to be an async function, it needs the asyn function in current visible context.Any workarounds? or am I chasing the wrong things?

Confused about architecting my next web/mobile app

Warning, wall of text.I've started a personal project which involves building a website that has user login/registration (including a backend where users will be able to do something) and an app that will enable the user to do almost the same (but it will be a native app), plus call a few other APIs.Now, the website itself will have a few static pages (i.e. home, FAQ, About, Features, etc). The main focus will be on the backend - in other words, the interface once the user logs in.This is my first time building a Node.js app (have been a front-end dev for a while) and it seems very simple. The last time I was working on backend it was with PHP (during 5.2.x days) and ASP.NET MVC 4. So, it's been some time, but not too long for me to forget all the basic concepts and principles.The way I envisioned this website to work is to have everything served by Node (jade templates, including the user's backend, etc). In addition, I will have 4-5 API endpoints that the mobile app will call. In my opinion, the frontend JavaScript required in this case would be minimal - maybe some events and that's all.I've started working on this and it is going alright - I've had some issues. For example, I've been having issues coupling passport-local and Json Web Token. I would like to use JWT instead of session ID for authentication, but I'm having issues making it work.However, the more I've been reading the literature online, the less inclined I am to believe that this is the right approach. It seems that, even with Node, the focus is still heavily on the frontend, whereas the Node is just providing the API endpoints. Whatever example I find seems to be using Angular or Backbone. For example, while looking for a way to get JWT to work, I've found a dozen articles saying "oh, just send an AJAX request via Angular/jQuery/Backbone, obtain the token, and then add the token to the Auth header".I am familiar with Backbone and would be open to learning React and/or Angular. At my workplace, we use Backbone to render web components, and all they do is pull data from an API and then get rendered.I am perfectly fine with this more front-end heavy approach as well - I'm not too deep into the app, so I can scrap it a little bit and restructure it, but I would like your advice on which approach to follow. Focus more on the frontend or the backend? Or have a nice, even split between the two?

Node.js Beginner Question: How to properly organize api code?

Hi everyone, Java developer here who wants to get into nodejs development. My goal is to create an Restful API which accesses a MySql database and returns values. I have made it work, but all of my code is in server.js currently.How I understand it server.js should only start the server and initialize the application. Is it the right way to encapsulate funcionality in modules?If I think in an object oriented way I would make at least one module which provides the database access and reads the data from the database. Another module which sets the REST routes and handles the requests.Does anybody have a simple example which shows that? All tutorials I find seem to be "How to create a Restful API the quick and dirty way".

How to create a PUB/SUB system like Meteor with Express or another framework ?

I know there's socket.io, but I can't find examples where it is as ''simple'' as in Meteor. What I mean by that is :The client subscribes to a ''channel'' with custom arguments, and the server sends custom responses to him. With socket.io, the data is generic and not customised per client. I saw some way to create custom publications but I find that it was really not a good idea (sending the parameters in the string of the channel).Basic example :Client subscribes to : My friend's posts (like facebook timeline) or my notifications.Server subscribes to RethinkDB or anything that can give him this information in real time.Server pushes the information back to the client when it receives the data from its subscription.In Meteor, this would be like :Meteor.publish('myNotifications', function () { return Notifications.find({userId: this.userId}); }); Meteor.subscribe('myNotifications');

Common practice request; BabelJS, Heroku

I'm evaluating Heroku, a first timer here. I'm generally fond of transpiling my src using BabelJS, enabling me to future proof (read: use the fun stuff) my projects. Here's my general setup:package.json{ "main": "build/index.js", "engines": { "node": "4.2.2" }, "scripts": { "build": "babel -d build/ src/", "postinstall": "npm run build" }, "dependencies": { ... }, "devDependencies": { "babel-cli": "^6.0.0", ... } } But this will not compile on Heroku as they install for production, as expected. Easily solvable by just moving the dependencies out of dev, or committing my build/ into repo - however, I'd like to avoid both. I do not like having the build in repo, and I do not like having dev-dependencies specified as dependencies.How do you do it?I also realise this is bike-shedding, but it's a pet peeve of mine so I figured I'd ask.

Suggestions on architecture/ libraries to use to consume an API and store in DB

The app I want to make is a bit more involved but the server side, which I want to start and finish first will do this.Pull data from an OAuth REST Api.Store the raw result into database.Pull data from different Rest Endpoints to get information relating to the first pull, store in database.Pull all this information from the database and store a data structure that is more clear on the data I care about.Create Rest Endpoints exposing this new data.Create some kind of timer that goes through and checks a particular query and notify the user.Essentially this app will allow the user to create a query and the app will notify them when those conditions are met.The last bullet point is a complete unknown to me.I was thinking of using - Node - Typescript - Grunt - SequelizeAs the main stack for the server. Any suggestions for architecture or frameworks I should look into?

Question about TCP raw-socket programming.

I am trying some basic socket programming in node js. Below is some code to send a TCP SYN packet. It does send the packet, and the target will respond accordingly. I used wireshark to capture the packets, and confirmed that a correct packet was sent and a SYN + ACK or RST + ACK is received. However, the s.on("message", func) never prints anything to the output. I cannot figure out why.var raw = require('raw-socket'); var crypto = require('crypto'); var ip = require('ip'); var s = raw.createSocket({ protocol: raw.Protocol.TCP, generateChecksums: true }); // source port 20 to destination port 80. Packet length 20 with SYN flag set. Other flags are zeroed. var p = new Buffer('0014005000000000000000005002200000000000', 'hex'); // generate four random bytes for the packet sequence. crypto.randomBytes(4).copy(p, 4); //build pseudo TCP header. var genPseudoHeader = function (srcIp, dstIp, tcpPacketLength) { var pseudoHeader = new Buffer(12); pseudoHeader.fill(0); pseudoHeader.writeUIntBE(ip.toLong(srcIp), 0, 4); pseudoHeader.writeUIntBE(ip.toLong(dstIp), 4, 4); pseudoHeader.writeUIntBE(6, 9, 1); pseudoHeader.writeUIntBE(tcpPacketLength, 10, 2); return pseudoHeader; }; // this gets absolutely nothing. s.on('message', function (buffer, address) { console.log("received " + buffer.length + " bytes from " + address + ": " + buffer.toString("hex")); }); // calculate checksum using utility function. var sum = raw.createChecksum(genPseudoHeader('192.168.40.100', '192.168.40.1', p.length), p); // writing checksum to TCP packet. p.writeUIntBE(sum, 16, 2); console.log(p); function afterSend(error, bytes) { if (error) { console.log (error.toString ()); } else { console.log ("sent " + bytes + " bytes"); } } // send packet s.send(p, 0, p.length, "192.168.40.1", function () {}, afterSend);
