Pusher-client latency check

How can I see what latency my socket connection has? I was reading stuff about ping and pong messages, and that they are used to keep connections alive, but have no idea how to use them.Googling for it also didn't help, would be nice if somebody can help me here :)And the reason why I need this: I am trying to buy something as fast as possible, and need to optimize the location where my program is hosted at, because I don't see any other bottleneckt that would slow it down.

Node reconnection issues

In my web app I'm using socket.disconnect() and then reconnecting later in the program. A simplified version of what I'm doing is this:var socket = io.connect('localhost:3299') // code socket.disconnect() while (condition) { socket.socket.reconnect() // the two sockets is intentional // more code socket.disconnect() } My issue is that when the socket reconnects, it sends duplicate updates - so when the loop has run 1 time the socket sends 1 message when I use socket.emit(), 2 times it sends 2 messages, etc etc. Anyone know what's going on here?

Parse csv and insert into mysql with Sequelize

Hi,I'm trying to parse a csv file and then insert the data into mysql with sequelize. Code below: var fs = require('fs'); var csv = require('csv'); var Device = require('./models').Device var input = fs.createReadStream('./csv/test.csv'); var parser = csv.parse({ delimiter: ',', columns: true }) var transform = csv.transform(function(row) { var resultObj = { model_name: row['Model Name'], imei: row['IMEI#'], serial_number: row['S/N #'], meid: row['MEID#'], esn: row['ESN#'], mac_address: row['MAC#'], exfactory_date: row['Ex-Factory date'], po_number: row['PO#'], packaging_number: row['CN#'] , sw_version: row['Software version'], fw_version: row['Hardware version'], hw_version: row['S/N #'].slice(2, 4) } Device.create({resultObj}) .then(function() { console.log('Record created') }) .catch(function(err) { console.log('Error encountered: ' + err) }) }) input.pipe(parser).pipe(transform) After running this code, new rows are inserted into the db, but they are all 'null'. I can't quite figure out why - can someone explain to me please?

Can you recommend cheap (or free!) hosting for a personal node app which does a lot of web scraping?

Hi. I am planning a personal app / showcase which is basically a souped up RSS reader. I am looking for the cheapest possible way to host it (free would be great). I'd want to use Express / Postresql but I am flexible on architecture / stack, as long as it's node based and not too obscure (not keen on Meteor). What hosting solution do you recommend?Requirementsonly accessed 20/50 times a daymust be able to run cron jobs to scrape web pages, say about 100 per hourthe same cron jobs should allow me to render pages server sidewith time the data stored may get hefty (I am OK with saving processed data to files and use the DB for metadata only, if it helps)https and password protectionThanks in advance

Can I have your thoughts on these two architecture possibilities?

Hi allI would love your thoughts on the items below.I am building a product which analyses log information.In a nutshell a large number of log data will be sent to a load balancer, which will then be distributed to a number of servers for processing, and finally get stored in a database.Option 1The load balancer sends the log data to a few single core servers. The node app on each server processes the data (cleaning, extracting relevant data, etc.), and either inserts or updates into a MongoDB database.Option 2The load balancer sends the log data to a few single core servers. The node app on each server encrypts the data and passes it to a message queue (e.g. RabbitMQ) run by a third party (e.g. CloudAMQP.com).Another bunch of servers takes the the data off the queue, decrypts it, processes it, and inserts or updates into a MongoDB database.~~~~~~~~There are pros and cons to both.Main pro of option 1: much more simple infrastructure.Main pro of option 2: more logical setup (i.e. each node app has a clear responsibility - producer or consumer).I like option 2 the most as it seems logically correct to me, and I like the idea of the first node app just grabbing the data and passing it on, rather than having to worry about any processing.However my worry is I am overcomplicating things, and in fact maybe the first node app has roughly the same performance in both options (process, insert into database vs. encrypt, push to queue), so it may make sense to choose option 1.Any thoughts appreciated.Thanks!

Creating separate instances of a game using Node

The game works fine with less than 50 people, but gets way too crowded if there are more than about 50 people on the server at once, so I'd like to make it so that if there are more than 50, they connect to a new "instance" (?) of the game. I'm unsure of how to go about this. Do I need to use "clustering"? Would I need to use Node's rooms feature and then process the physics for each room separately, sending the clients only the data for their particular room?

Async best practices

I'm somewhat new to the world of async JS/node, and am having a hard time finding the best approach(es) to the whole "everything must be async" paradigm.Let's say you want to test sending a file. You get the file size that you're sending/have sent, and then compare it to the resulting file size after the far end finished downloading it. Short of setting /*jslint node: true, stupid: true */ how to ensure the steps are synchronous, but within the asynchronous mindset?I suppose a more concise question might be that according to this I should get the file size with something like:fs.stat(`test.txt`, function(err, data){ console.log(`file size: ` + data.size); }) Which isn't useful if you want that information later. And the best way around that, which I've found, is to do:var fileSize; fs.stat(`test.txt`, function(err, data){ fileSize = data.size; }) Is that the correct/best way? Does it even actually result in a synchronous call, or would it be possible that I somehow get the remote file size prior to the local one, and fail the comparison due to some IO issue? Is there a better/cleaner way to accomplish this? Also, I would personally prefer var fileSize = fs.stat(...) direct assignments instead of 2-stepping everything, is there a way to do that in asynch syntax (that's lint compliant)?

module.exports best practices?

I'm having trouble determining the difference (if any) between these three expressions. It seems to me that they would all achieve the same end result. If so, which is the "standard" or largely preferred format and why?// exporting a function with nested functions module.exports = () => { foo() { } bar() { } } // exporting an object literal module.exports = { foo : () => {}, bar: () => {} } // export expression with named parameter module.exports.foo = () => { } module.exports.baz = () => { }

Looking for guidance on releasing my open-source application

Hello,I'm about ready to release my open-sourced project located here, and I think this is a really good application idea. But I don't know much on how to "release" open-sourced projects (or projects at all). So this application is like phpmyadmin, except much friendlier, not as many features, and is database-agnostic.But I'm confused on how to "release" this because the user has to clone this project, then compile the typescript into javascript, then run "node app.js" and it launches a localhost web app. But it should be easier for the user. I don't want them to have to typescript-build it, then run "node app.js." I just want them to access it right away. So what should I do? I don't know how to release a localhost website. I want the user to be 1 step away from seeing the final prodict. Not have to clone, build, then run "node app.js." I don't know what I want the end result to look like. Is there an open-sourced "website" that's released like this?I also have another question. This is a tool users use to connect to their database. But in the rare unlikely chance that this tool corrupts their data, I don't want to be in trouble for that. This is an open-sourced free-to-use web application. I wanted to release it to help people, not to be in trouble. Do I have to worry about this? Like... can I get sued if my project messes up their data, or held responsible?Thank you for the help.

Having trouble understanding the benefits and point of using an .env file

I've seen a lot of node projects that have a .env file and then use the dotenv module to set your values on the process.ENV object.. things like keys and secrets and other constants needed throughout the app.I have seen this touted as a best practice because it follows 12 factor app principles and things like that, but it's just not making sense to me. Normally what I've always used is 2 config files, one for dev and one for production. The production config file gets all of it's values by accessing process.ENV, but the development config file has all of it's values hardcoded. Depending on the value of process.env.NODE_ENV, I choose whether to use the dev config object or the prod config object.All of the keys, secrets, and constants in the dev config have zero affect on the production environment, so even if a dev wants to be malicious with an API key or something, it really doesn't have an effect on anything of value.Because of all of the above, I'm failing to see the benefits of using the .env file. From what I've seen, the project normally has a dummy file like .env_example to provide guidance to anyone using the code, but it's their responsibility to create a .env file and fill it with key-value pairs. Also, it's promoted as a benefit to not have this file checked into git, which is why everyone needs to create their own .env file in the first place. This seems like a lot of extra work to me, and I'm not really seeing how it's more secure than using the config example I described above.I have a feeling there is more to using the .env file than I am realizing, so I'm looking for advice on this matter. I've never worked on large teams or big open source projects, so I feel I may be missing something here.Appreciate the help.

I've built a site to help programmers find a team for their project ideas

Hello,I've been working on a project as a way to teach myself programming. The site is called 42exp and is built on node/postgres. The relevant github repoAs a new/self-taught developer , i faced two problems which were driving factors to build the site.Lack of project ideas - I basically got tired of doing to-do lists all day for every language framework. I believe that the only way to gain practical knowledge in a language is to build a product which you would find useful.Lack of a team to bounce ideas off - Collaborating with other devs is something i could never experience . This i think is a major stumbling block in my learning. I liked django/node/DRF and wasnt comfortable with design. It would've been awesome to work with a designer who could take care of deciding how a site looks while i look into the backend or vice versa.The site is still new (buggy is probably a better term) , but i would love it if you guys can try it out , provide feedback and start your own projects.Thanks for the read, KJ

You know how Wordpress allows you to add third party plugins, same for Eclipse and other apps. How would I go about that in NodeJS ?Extension points ? How exactly does that work ?

Help debugging a node app

Hi guys,I'm a relatively green web developer (~2 years professionally) who has plenty of experience writing code for Node/React apps, but little experience managing performance or DevOps-ish type stuff.I have a hobby app that typically has anywhere from 15-30 users at any given time. It is a Meteor app on a Digital Ocean server deployed with mupx (Docker).I run into weird performance issues that I just don't know how to properly debug. Its very difficult to reliably reproduce -- I'll get messages from people saying my app load time is really long (sometimes for no reason I can see my CPU usage will shoot up to >100%).I decided to switch to a PaaS to offload some of the DevOps stuff I'm not familiar with, but it hasn't really helped. I have 2 containers running which seems like it should be more than enough for what I need, and yet with just a little bit of load it seems to take a massive performance hit.CPU spike with just one hitInitial load timeIf I spin up ~30 instances of the site, load time jumps up almost 10xEven if I cache the relatively large initial data dump ( a collection of ~4.5MB) and skip the database trip entirely, it still takes about 3 seconds to load everything into memory.I'm not asking for anyone to solve this problem for me, just looking for advice on where to begin debugging something like this. Thanks guys!

understanding callbacks with a specific example.

Hey folks, I just got back from my first hackathon, and I was on a team using node-mysql to get data from a mysql database then return that data for front end use. We ran into an issue and ultimately decided to solve our problem a separate way, but I have a specific question about this particular section of code, and understanding how to get it to work.It took a bit to realize there was an async aspect of node because none of my teammates were familiar with it. We noticed things weren't printing in the order we expected, and we found out callbacks were needed but we could not implement them properly ultimately. I don't want to let this go though without understanding. I read multiple articles on call backs, and I couldn't wrap my head around this which is disappointing me.getData(input){ var output = 0; var mysql = require('mysql'); var connection = mysql.createConnection(); //other connection and server setup here connection.connect(function(err){ connection.query('SELECT * FROM table WHERE tableData = input', function(err,result){ if(err) throw err; output = result //console.log(result) connection.end }//connection.query close }//connection.connect closed return output; } start(){//for testing the above function var arr = getData(); console.log(arr) //query data is expected as the result, but 0 is returned } start();//run the start function Can anyone help me figure this out? I kind of understand at a surface level what's going on with asynchronous code, but I don't understand how to make it work with node's syntax, and I feel like node related documentation is pretty bad, or I'm not smart enough for it (or maybe both).

Need help with Yield and Generator functions

I'm still trying to grasp the concept of generator functions and yield so bear with me.I'm using Adonis.js and things are going well for the most part, but I've hit a snag. I'm trying to ajax call to a url, which then uses the Plivo library to send an SMS, then returns the result (if it sent or not). The code is executing and Plivo is sending the sms and console.logging out the result, but the output json is being returned to the front end before Plivo is finished.So my question is: how do I wait for Plivo to finish sending the SMS before returning the json to the front end. Adonis allows me to yield a DB call, so the code "waits" for the DB result before continuing, but if I yield the Plivo call:var output = {} yield Plivo.send_message(params, function(status, response) { if (status === 202) { output.status='success'; console.log('success'); } else { output.status='fail'; console.log('fail'); } }) return response.json(output); I get an error about "You may only yield a function, promise, generator, array, or object, but the following object was passed: "undefined""Any help would be greatly appreciated.

Authentication with Express + React

Hi, I'm working on a project and I need to add user authentication. I have an express api, and a React front-end.I started adding authentication with Passport js and JWT, but I've been reading this is not a good usecase for JWT and it's not really secure. But it seems very straight-forward to me.How do I go about using Passport Local Strategy, with sessions, and combining this with React? I don't really get how React is supposed to 'know' about this session and how I can authenticate further API calls?So let's say I make a post from my React app with user credentials, my api takes this data, and checks it against the db. If it succeeds it creates a session. But how does this get back to React, how can I check on the front-end if a user is authenticated?Maybe I've just got this all wrong and it's way more simple than I imagine?Any help would be appreciated.

I was curious how I would go about storing the image and connecting it to each certain user. I am currently using Mongoose schema for each user. I was reading about using S3 as a place to store all my images but I wasn't sure how to go about that and connecting those images to the users and implementing it into the schema. Thank you!

Electron Node.js module for controlling Spotify+iTunes on macOS

Hey,Here's another module I wrote for use in one of my projects: node-osx-mediacontrol.It aims at allowing a client to listen for playback events on Spotify or iTunes (play/paused/stopped) and allowing playback control (start playback, pause, stop, etc.)In this first version you can hook up a callback to receive playback state from iTunes, as well as play/pause iTunes. I thought I'll publish it early and then add functionality, that way everyone can (if they want) contribute very early on.node-osx-mediacontrol is available via npm (the github link is on the npm page)The project I'm using it in is DeviceCast: http://ift.tt/2qB9TsN's an app that allows streaming of macOS audio to either Chromecast or UPnP devices (Jongo speakers, or Raumfeld devices). It's a heavy state of flux, but streaming to Chromecast and Raumfeld works great.It's quite smart in that it will e.g. stop the streaming when iTunes stops or start streaming the audio to the most recently connected device when you start playing in iTunes, etc.Anyway, have a nice day everyone.

Is it worth sticking to mongodb with GridFS or should I just use MySQL?

I discovered today about the little fact that BSON document sizes are maxed at 16mb. Because of reasons from what I can tell. Before someone says it, yes, I read the docs on mongodb about memory issues. I find that to be a shit excuse. Maybe 2gb or something like that as a max makes logical sense for a server environment, kind of. But not 16mb. But whatever. That's more of a water cooler discussion.I see there's a GridFS solution. Anyone with experience using huge datasets using mongodb/gridfs? Is it worth it? Pain/struggle? Or should I just have nodejs hook to mysql and call it a day? I'm sort of at the point that I should choose now before a point of no return. Well, super painful return worth of rewrites.The thing that just threw me off about this is hearing a bunch of hype from the past few years how mongodb is somehow magically better at huge data than MySQL. Doing research lately, I've been reading that it's not the case as long as I index my tables properly. So, just wondering if anyone out there has a personal opinion from experience about mongodb and large data. I could very well be missing some vital bits of info that makes everything make sense. I'm only 2+ weeks into nodejs.Thanks for any input.

Mongoose/Mongodb Cross Collection Transactions/Rollbacks

I will preface with I know mongodb isn't designed to be heavily bound by reference based relationships (Thats what good ol SQL is for), but I have inherited a very heavily reference based mongoose schemas. Pretty much everything is reference bound between different collections. Its really close to how a traditional SQL DB looks.So to my understanding mongodb has transactional locking at the document level, but it doesn't support cross collection transaction protection. I am debating on writing a functional wrapper above mongoose to protect against creating orphan/malformed records (these really aren't documents). Has anyone else had a similar scenario or know of any libraries that assist in this issue. Refactoring isn't an option at this point.Any suggestions are greatly appreciated, thanks in advance.

Express: how to handle errors into a route handler that uses promises?

I'm trying to understand what's the best way to handle errors in express.I have a route handler that does some sync computations in the beginning, and after it is done searches the DB. After the DB returns, some more computation is needed.It's a very common sequence of actions so i'm sure you all did it.I have implemented the DB search using the promise flavour instead of using callbacks.I want to understand how to properly handle errors depending on where I need to raise/throw errors.So, here is the pseudo-cod, please check the comments for clarification of my question:router.post('/test', function(req,res,next){ // some sync computation, eg. read headers let header1 = null; try{ req.headers['header1']; }catch(err){ return throw(new Error('header not found')); // is this ok here? } db.find({ where: { id: header1 } }).then((data)=>{ // do some computation with data data.value1 += 1; // if an error occurs here, or I want to generate an error on purpose, how should I handle it? // 1. throw new Error('blabla')? -> will go to the catch where maybe I can return next(err) // 2. return next(new Error('blabla'))? }).catch((err)=>{ return next(err); }); } I hope my question makes sense.tldr: if an error happens or I want to raise an error into the .then function of a promise, should I directly return it there thought return next(err), or throw the error to pass the handling to the .catch method?

As far as I've seen, in all the examples about how to set up a Node.js HTTP server, the host and the port are indicated in the function "listen" of the net.Server object that Node.js handles.

Is there anything I should be warned about in regards to security or in general before doing this?Many thanks.

How to handle an error from a stream that you're piping as an HTTP response?

Here is a gist with both the server/client code, but I'll post the server code here as well:const Router = require('koa-router'); const fs = require('fs'); const generateFile = require('./generateFile'); const router = new Router(); router.post('/getFile', async (ctx) => { const filePath = generatePDF(ctx.request.body); const rs = fs.createReadStream(filePath); // This might throw an error rs.on('error', (err) => { ctx.response.status = 500 // This isn't working. The status code of 500 doesn't seem to get sent to client. ctx.response.body = err // I don't think this `err` object makes it to client either. console.log('hi'); // This DOES run when there is an error }); ctx.response.type = 'application/pdf'; ctx.response.body = rs; }); Here is basically what I am trying to do:Create a PDF stream from the request body sent from the client.Pipe that stream to the HTTP responseHowever, in some cases the PDF might not be generated in which case createReadStream will throw an error.In the cases where there is an error, my fetch code in the client always gives a response of 404 even though I set the status to be 500 in my server code.tldr: Why isn't my server side code sending the right stuff to the client when there is an error? And am I not doing this error handling properly in general?

ettiquette for npm package ownership & forks

If there's a package with the right name, no commits in three years, more than a dozen issues & outstanding PRs.. should I publish a fork or merely be a contributor?My commits thus far have added significant features far beyond what the original code base intended. I don't think any part of the owner's code base remains unchanged aside from a few dependencies (which have changed to ES6 syntax anyway).At first I made a PR against the repo which resolved all the outstanding issues and included all the PRs which seemed appropriate. In the PR comment I suggested that the owner add me as a collaborator or consider changing ownership.He said he "was open to transferring ownership", so then I pushed a bunch of additional commits adding additional features. A few days later he added me as a collaborator.I guess the pointy end of my question is how important package ownership actually is, if at all ?To explain, I'm an amateur, but it's conceivable that at some point in the future I might want my github profile to look attractive to some prospective employer. Do people reviewing my stuff care or notice whether I'm contributing to packages I own?In addition... it's shallow & pretentious of me, but it's nice to publish packages and see how many downloads they're getting on npm, or stars they're getting on github. I think it will always bother me that these stars or downloads won't appear under my account.Obviously, if I was working with others on a package then it wouldn't matter at all that the package is owned by some organisation or whatever. But in this case it kind of feels like I'm investing a lot of time and effort in something only to benefit someone else's reputation who, at this point, is pretty much just camping on the namespace.So yeah, thoughts / guidance very much appreciated.

stream consuming pace

Hi,I have a limited understanding of nodejs streams but I'm interested on how the data in each piped "consumer" flows. E.g:loadRemoteFile() .createReadStream() .pipe(progressReportTransformer) .pipe(unzipper) .pipe(someOtherTransformer) Imagine the upper situation where someOtherTransformer might "block" the stream by not calling done asynchronous but waiting for an async operation like creating a database table. It can work because a stream.Transformer can delay the data flow by not calling done() right away.Now is it a problem for the progressReporter, meaning will the progressReporter stream delay reading the next chunk until the one later (someOtherTransformer) in the "chain" finishes it's job?I don't know if I should imagine this process as a synchronous operation where the first pipe in the chain reads data from the readStream and when finishes pushes it/something to the next pipe for processing and this first pipe will only read the next chunk when the last pipe in the chain finished OR I should imagine it as if an intermediate pipe in the chain finished it's operation and pushed it's state to the next pipe for processing it gets ready for another chunk?I don't want my progressReporter to read (and report) faster than my latter async operation finishes it's operation.I hope I was clear enough.Thanks

Is it worth studying Node itself, or Express?

Node has always been a bit of a puzzle for me as I've equated Express to be a lighter weight/less opinionated analogue of Rails or Django for back end Javascript. I'm in the first chapter of "Express Blueprints" and gaining clarity on how the server side works, it even has a chapter on Koa towards the end.I'm just curious if I should also pick up some learning materials on Node itself (I see there are a lot of them, more than Express actually). And if so, what benefit does studying Node itself yield?EDIT: Besides web apps I also plan on making scrapers and bots that run on the server side, which is another reason why I'm wondering about Node on its own and whether its a more suitable foundation for these types of things.

Sharing/Storing just the diff instead of a full text?

Right now I'm thinking about how to propagate and store changes across clients.For example, if someone applies a 40 character diff to a 20,000 character string:what's a more efficient way to transmit the diff than to send the entire 20,000 character string?what's an efficient way to store the diff (e.g. revision history) than storing the whole 20,000 character string twice?Wikipedia is probably a good example of where more efficient diff storage would be a good idea. They probably store only the final copy and the entire diff history, rather than each history entry being a full copy. I wasn't able to find anything related to this on google.I'm mostly interested in good reading material or npm libraries for this subjects.

User authentication passport-facebook in iOS app

So I am wondering what to do with the small API that I have created. In the API I have the ability to login with Facebook. Right now I am doing it stateless as I want to be able to do it on both mobile and web. Therefore it returns a jwt token that the user stores and uses each time he/she calls the API. This work well in a browser and through postman and now I am starting to work with the mobile part. I want to know more about how you implement this into an iOS app. Do you just create a 'fake' button that makes the needed get request, or do you use the FacebookSDK somehow? The logical way for me right now would be the first one, but I am not sure, as I have not worked with this before..Hopefully someone can shed light on this minor headache of mine.

Setting up authentication in Express vs Meteor

Hi,I was looking into studying Express vs Meteor as my 1st back end framework. A post on stack overflow said the additional weight of Meteor gives you faster MongoDB and websocket setup, and hours of time savings with user authentication.I wanted to learn a lighter framework like Express because I plan on making lots of little scripts and bots, so that user auth thing is a bummer. Is there any way to speed up the process with Express using say a 3rd party module (I know nothing about Express right now)?

What's a good open source RESTful microservice to use as a reference.

I am looking to restructure one of my companies micro services that utilizes Node, Express.js, Swagger docs and TypeScript. The microservice is basically just a compilation of REST end points for making calls against our MySQL database. Looking for a good example of project structure and coding practices. Obviously if the app is more robust than just that, I can still take a look at it and pick apart the things that matter for my work. Thanks!

Is it possible to compile a js file?

I understand that node.js is an interpretator, so it means it reads every line at a time instead of turning it all into maching code. But I know there are a few modules that can turn it into an executable. Has anyone had experience with any? If so what is the best one and does it also deal with modules that your code is using?---EDIT--- If you can't compile it, is there a way to "lock the source code" so if you were to give it to someone they couldn't see any of the written code or a way to stop the user for editing it?

Express static file routing

I have been trying to search the proper way to solve this problem, but have had no luck. I am trying to get express.static to point to the same directory, completely ignoring what's happening in the requesting URL. My directory is structured like so:views --view1.hbs --view2.hbs --etc... public --css --main.css --js --main.js --images --bunch --of --images My current static route is set up like so:app.use(express.static(path.join(__dirname, 'public'))); And for routes which come from the root directory, this works as expected. So for example:http://mysite.com/home http://ift.tt/2r4jRnn As soon as I start to add another level to the url, this breaks down. For examplehttp://mysite.com/archive/2 Routes incorrectly to/public/2/folder/resource.xxx Instead of/public/folder/resource.xxx So how do I setup my static file router so that a url such ashttp://mysite.com/any/number/of/levels/into/infinity Always serves static resources from the public folder route directory? I'm pretty new to building this kind of application, so any guidance is appreciated.

recommendations on scalable video upload implementation

We currently have a node based system that enables upload of large video files (500 mb and up). The video stream is passed to the server and streamed directly to s3. However, our solution is not scalable as the streams require too much CPU. I am looking into browser-based uploads directly to s3 but still investigating securing issues. There is also the possibility of setting up a separate uploading server for handling uploading requests.Does anyone have recommendations on solving file upload scalability problems with node?

What's the best way to load assets in staging/production environments with nodejs?

I'm going to start a new nodejs application and I'm not sure what approach to choose to load my js/css files on staging and bundle them to production.In my work, we have an app that is setup like this:/config/all.js: this file contains arrays with filepaths. Different arrays for lib assets and own assets. This means that everytime a new file is added, I need to include the filepath on this file.In my footer.jade:if (process.env.NODE_ENV == 'development') for jsFile in jsFiles script(type='text/javascript', src=jsFile) else script(type='text/javascript', src='js/application.min.js')where jsFiles is the array with all the javascript filepaths the app has to load. In staging environment, we run grunt build so grunt takes care of concatening and bundling all assets. We're not using ES6 import.Is this a good approach to this problem? Should I be using webpack (though I'm not 100% sure what it is yet) or something?

In need of some help in relation to authorization with JWTs / Passport.js

I'm currently doing a hobby project for a friend which involves a custom CMS and a front-end server to serve the data. I've posted on here before but after two weeks of struggling I've not advanced too much.On the back end I've an express server running an API for the blog, users and other schemas.On the front-end I've an express server that serves the pages using the templating engine handlebars.Currently I've managed to authenticate users to the API using Passport and JWT, on login I'm storing a JWT with permissions in the cookie storage within the browser (no localstorage access as it's not a SPA)My issue is that I am struggling how to implement authorization on the client end for access to the admin panel.Should I decode the JWT on the client-end and read the user role then serve the pages if the admin pages if the user is an admin or should I be sending every request to access the admin section of the front-end to the API for a verification check then serve the page on the front end if the check passes.I realise this would have been much easier if I had just combined the front-end and back-end into 1 app but I was looking at trying to separate them as I've read it's a better practice.Any help would be greatly appreciated, thank you.

I looked into Directus, but the Node-based version is still being developed (I'd like to avoid PHP).Does anyone know of a database manager/CMS/REST API panel that I might be looking for?

Why are NoSQL databases usually paired up with Node?

I've been doing some research for databases for Node.JS and almost everyone is recommending NoSQL type databases, like MongoDB.I see that NoSQL is not that great for relational data, but that's where I'm getting confused: Most business applications (or social networking type apps) have relational data. For example, let's say I'm building an application in Node.JS for a school that has students, teachers, classes. You can see there's alot of relationships in there.Would you recommend using NoSQL? I know that you can use mongoose to enforce relationship databases in NoSQL databases though. Or would you go for a SQL database? Why does the majority recommend using NoSQL when using Node?

Our app (Node / Express) has some data that is generated during a user session, and we need to have quick access to it. I was wondering what the best way to do this might be.For more detail:The initial data is requested from an external server, then processed. It is this processed result that we must store as long as the user's in session.Data size should be about 10kb of size per user on average, 25kb per user tops. Hopefully one day we'll have hundreds or thousands of concurrent users, so it'd be great to design with that ambition in mind.We need very quick access to it - we might want to feed it back to the user dozens of times per session.It definitely needs to live in the server and not in the client, as it is used in processes there.We might want to store it into a database some day after the session has ended, but for now the priority is to have something that is only persistent for the duration of the user session.I have explored a couple options, including:express-session + Redisnode-cacheI am still a beginner so there are some questions you might be able to help me with:What's the best method in your experience? Any obvious ones we've skipped? Any trade-offs we should be aware of?Why is Redis such a popular system for this? In my novice mind this seems like a rather simple operation (just write some data to system memory, and delete it on certain conditions), so I'm wondering why one would layer another system into their stack, instead of simply reading and writing from/into memory with the help of a package.Thanks in advance for your help.
