Good resources for becoming a Node Developer from a PHP Developer?

I am looking at job opportunities right now and would ideally transition from a senior full stack LAMP developer to MEAN (or some node based stack). I think it would be a pretty easy transition and enable me to grow professionally because I am pretty experienced writing server side applications in PHP and have done a lot of front-end javascript, in many cases node modules that were browserified.I had a phone screen today with a company that seemed great - but I'm worried they may not want to pursue me because they need a node developer and I am really not one, despite having lots of experience that is pretty close and a good knack for learning new things.I feel like the biggest challenge in the transition would be dealing with concurrency issues which I grasp conceptually but haven't had to deal with in real life.Does anyone have any suggestions for trying to improve my skills and knowledge a bit so that i'd be more desirable to a node shop?I feel like the obvious answer is to just build an application in node but I am also in the middle of a personal project to build up my experience with AWS so I want to get further along in that project first and my current job leaves me little free time for the last month or two.Something more like a book or just general advice from people who've made a similar transition would be very helpful.

I have ten individual node packages (microservices) in ten separate repos. I would like to merge them into one, unified package. Each individual package would also depend on the unified package. Possible?

Ten microservices, some of which depend on each other (eg. User, TodoItem, ...). Currently, each microservice has its own repo and npm package. I would like to merge them into one npm package while maintaining individual repos (open to opinions on that choice, though)Each microservice will provide interface code so that other microservices can call it//Code owned by the TodoItem microservice. Can be called from other microservices // TodoItem/index.ts const addTodo = (someDescription: string) => {...} const removeTodo = (todoId: string) => {...} export { addTodo, removeTodo } Currently, I can import the TodoItem code from my private npm package:import TodoItem from '@user/TodoItem' However, I would like to use the "aws-sdk" approach, where all of my packages are bundled:import { TodoItem } from '@user/my-app-sdk'; The "my-app-sdk" node package would really just import the various microservices and then export them. Something like://my-app-sdk/index.ts import TodoItem from '@user/TodoItem' import User from '@user/User' export { TodoItem, User } Is this possible and practical? Bad design? Am I in for circular dependency hellscape?

Debugging Help: Infinite loop caused by seemingly accepted and rejected promises...at the same time?

This is the offending code. I've been using callbacks somewhat successfully, but I am new to promises.download is from https://ift.tt/2vhRXEz understanding is that the .then code will be executed if the download is successful, 'exclusive or' the .catch code will be executed if the promise is rejected. Which would imply that a .catch should not run immediately after a .then, but that is exactly what is happening in my output.function getData(callback) { download(downloadUrl).then((xmlData) => { parseData(xmlData, callback); }).catch(retryDownload(callback)); }function retryDownload(callback) { console.log('Error downloading xml data.'); setTimeout(() => { getData(callback); }, 300); }console output is: 1. Sucessful parsing output 2. Error downloading xml data. 1. 2. 1. 2. etc to infinity.Any ideas? Perhaps I misunderstand promises?

Help debugging performance issues

Hi everyone,I've been dealing with trying to debug a performance issue for the past few days that seems to be CPU bound but I am having a hard time telling if the issue is what I actually think it is. I've been using the debugger with chrome://inspect to run CPU profiling and have being reading many articles that tell me that the "wider" the graph bars on the chart are, the more likely those functions are to block the event loop.It appears to be a function that calculates the string distance of two strings but I am not entirely sure if I am reading the chart and other options in the profiling correctly.Does anyone have any tips on how to debug NodeJS apps for performance issues? Has anyone dealt with having to offload some processing power via webworkers or other libraries or switching some functions to AWS Lambda to avoid problems like these? I can post the cpuprofile file later when I have access to my work computer if that helps.

You ever have something you want to code but can’t be bothered. Like literally I’ve been bashing out the frontend and react is awesome, but now it’s time to do the backend and I really can’t be bothered...

I currently work as a labourer (it pays well, and I sleep well for once), so I’m too tired to do anything complex like backend work when I get home, and the weekends I’m normally still somewhat tired after a week of hard work, so usually I just do frontend work. But now there’s no more to do and the backend needs doing, but I just can’t motivate my self to do it. I’m thinking I may be losing interest in programming - again. If so, any tips to regain interest? Thanks a lot!

mid to large sized projects (npm packages) that use ES6 classes syntax

I wanted to peek a little into mid to large sized projects to look at their code, how they structured their project ... to learn and adopt it for my personal projects.tbh i didnt do a hour long search for those sort of projects but some google search aswell as npm/github but most of the larger packages seems to be created before ES6 classes where production ready and some newer packages use typescript instead of "old" js.1.) Some of you guys have some favs where you think that they have implemented classes the right way? (please dont discuss if you should use classes or not like eric elliot says ...)2.) Do you think typescript is the way to go for new projects in particular when you create production grade code for companys?3.) if you think ts is the way to go, which projects do you think are worth to take a look at?

How to detect if file is being written to

Trying to find a solid solution to detect if large files are being written to by another program/user. I have a method that works, but is potentially error prone (putting a fs.renameSync(file, file) function in a try/catch). Placing a file size check in a timeout will return inconsistent results as apps all write to files in different intervals, also slows down quite a bit when processing lots of files. Also lsof command won't work in this scenario cause I'm accessing network files that could be written to by other computers. Let me know if you guys have any ideas for this. Thanks!

Where is the best place to store a temporary file, that I need a consistent path for across all platforms (windows, mac, linux)?

So, I'm using node for a program that syncs your clipboard to a docker container's clipboard, and I need to create a file that is in the same location so that it can be shared in a docker bind mount, whether I'm on windows, mac, or linux. So, naturally, the file needs to have the same path on all those platforms. The file doesn't have to be persistent on starting or restarting though, as all it does is share a clipboard between the host and container. Any suggestions?

Express setup to handle deep linking...?

Hey friends, Been spinning up an Express API server which is also delivering the Angular6 client side bundle (MEAN6-ish?).I've got no problem with the routing when clients start on the root of the site, however I noticed that "deep links" directly into the app (which the Angular routing should be handling) is not working right...The closest workaround I came up with is to use a wildcard...but just wondering if there's anything I missed or could structure better?If I wanted to add static pages later on, separate from the client handler, could that work as well?// setup our API route app.use('/api/v1', apiRouter); // add the "public" folder to the static handler app.use(express.static(path.join(__dirname, 'public'))); // future request - a static handler for /privacy -- ? app.use('/privacy', (req, res) => { send('privacy'); }); // add the wildcard to catch / as well as deep links to /this/is/a/deep/deep/link app.use('*', express.static(path.join(__dirname, 'public'))); Any tips or advice is appreciated - thanks

Would you push to use NodeJS to write the COM sub-module of an enterprise application? Is it a safe choice?

I’m in a unique position. I’m the chief tech lead in my company (small software house) and I’m currently designing the architecture of an enterprise application for an important multinational client.One of the things the application has to do is manage the upload of huge files via browser and store them on disk, so my first go-to, for this specific task, was NodeJS. Other modules will be written in .NET or Java.One of my team members, however, pushed pretty hard to stop me from using NodeJS at all. He put forward several objections ranging from:his distaste for the language (“JavaScript is designed for the browser, not the server”)to security considerations (“an ex coworker of his who does security consultancy told him to stay away from NodeJS”)to “using this tech may make us look bad if the wrong people on the client’s IT find out”, given it’s not “enterprise like Java or .NET”He comes from a Java/C++ background which make him despise everything that’s not “as formal” as those ecosystems. I shut him down quickly when I saw he was being biased, but I took the last two points (security and enterpise-level) seriously.I’m still benchmarking based on our needs in order to choose the best tech among .NET, Java or NodeJS (which he would have done if I haden’t told him to), and because this is my project, I’ll decide what we use.However, the technical objections put forward are still looming in my head. The decision may be mine but I always consider my team’s opinion, and he put a lot of self-doubt on my original assessment, making me doubt of myself to a point.What do you think? Should I have not considered NodeJS for an software of the sort?

Passport.js: authentication seems to work fine, but can't keep users logged in.

I've build a simple app that allows users to log in through google using passport's google strategy and it all works fine.I'm trying to add a local strategy as well, but I can't find a solution.Database works fine as users get created during sign up process.Logging in seems to work initially as I get redirected to "/" as expected with successRedirect: "/". But if I try to go to any other route page, I'm not logged in any longer.I f i run req.isAuthenticated()it returns false. If I try to retrive req.user, it's undefined.Here's the code: https://ift.tt/2uZ43Dc, I tired to get some help on stackoverflow but with no success)It seems like authentication itself works, but somehow it doesn't keep up. If I run a console.log("req.isAuthenticated") right after signing up it returns true, but as soon as I go to another route (example: /), by running a console.log("req.isAuthenticated") in the get request of that route I get a false. It's like I can login but I can't stay logged in. Could this be related to cookies? Did I write something wrong? Does anyone know how to solve?

Error handling with express

Hi, I am a beginner in node. Recently I started building a website where signed in users can upload images. I use multer for that, I also set the max file size to 5 MB. When the file size is bigger than that multer throws an error. I tried doing some error handling (I am completely new to this). I built this simple middleware function:function error(err, req, res, next){ res.json({ message: err.message }) } This works but the problem is that when the error occurs this json data is displayed in the browser window:{"message":"File too large"}What I want to do is refresh the whole page with the error message displayed somewhere on my page. How can I do that? Also could someone please explain how error handling works cause i am very confused?Thanks in advance :)

Best way to install Node.js on a new (macOS) computer

Hi, everyone,On my previous Mac I originally installed the binary from the Node.js website and then, after some time, moved to using nvm (and then n, as nvm was pretty slow when opening a new shell). I'm setting up a new Mac now and I'm wondering what's the best way to do it. I also recall, at one point, setting up a Mac where I installed the binary from the website and then brew was complaining that node had files in _/usr/local/include_. Not that it caused any problems or anything, though.I know I can also install via Homebrew. I understand that the answer is "do what's best for you" but I'm interested in some thoughts and opinions from others.Thanks!

Hey everyone! I'm developing a nodejs app but there's a problem when I put the app online.I have a form where it's possible to upload an image, and in localhost it always worked correctly, but now in Google Cloud Platform instance it isn't working.I am using nginx as a proxy for port 3000 which is where I have the nodejs app running.Initially, 'Error 413 Request Entity Too Large' occurred, but I was able to solve this by adding the lineclient_max_body_size 10M;to the nginx.conf configuration file.The problem now is that when uploading images larger than 5MB, error 413 is not returned, but image uploading is not done either.PS: I use the formidable to handle the data received from the server side.

Problem with static files

Hi, I have an express app where users can change their profile image by uploading a photo. I use multer to do that. The picture's path is stored in the user's DB record (path is assets/uploadedImages/randomImageName). I use the path as the images src. In order to serve the folder with those images as a static file i tried doing app.use('/assets/uploadedImages', express.static('./assets/uploadedImages')). This works great for routes such as my home page localhost:3000, but when i have something like localhost:3000/users/userId this method stops working. I guess this is because of the / i have after users. How can i solve this issue?Thanks in advance ;)

HAPI - Route Handlers and passing additional data besides (request,h)

This is a snippet from my api.js that holds my api routes.Above this code is all the static route handlers. Auth/Login/EtcWhat you see below is the routes added dynamically based on my models.js which holds on the object classes that have api interfaces.I need to some how pass from the API call to the handler the class model to my db.js which holds the handler. Even just passing the name of the model I could resolve it by using models[model] in the db.js. Unfortunately this is seeming harder or more convoluted than I want.pre [] seems to happen at the time the route is called not when the api call is built so this causes issues with the model that gets passed into request.pre.model. The API call says it's path is /_api/Merge/Person but when it executes pre[] it doesn't pass the Person model. It passes the last model in the array which could be something like "Organization" and not "Person".for (var model in models) { routes.push({ method: 'POST', path: '/_api/Merge/'+model, options: { pre: [ { method: function () { return models[model]; }, assign: 'model' } ], handler: db.mergeObject.handler, description: 'Add/Update Object ' + model, tags: ['api'], validate: { payload: models[model].schema() } } }) routes.push({ method: 'DELETE', path: '/_api/Delete/' + model, options: { pre: [ { method: function () { return models[model]; }, assign: 'model'} ], handler: db.mergeObject.handler, description: 'Add/Update Object ' + model, tags: ['api'], validate: { payload: { key: joi.string().required() } } } }) } I'm not sure how to hard code a value in my routes. I thought I could use option.notes and store the object name but I felt like that was kind of lame and there could be a more sophisticated way of doing it.

Need somebody to hold my hand in getting my Express app online

I have a portfolio site online. I'd like to have it run with Node, so that I can have contact forms and other server-side functionality without having to touch PHP. So I wrote up everything offline first, using Express as a framework. The whole thing is effectively finished so I uploaded it all to my server via SFTP, npm installed the dependencies and so now it is on the server.The server's OS is Ubuntu, the HTTP Server is Apache. I know Apache is old, I'm a old man in a young man's body. It took me ages to move away from PHP in favour of server-side JavaScript. Plus this is only a portfolio site and not a real web application so I don't care so much about performance, I just want people to see how smart I am. Anyway I'm using Apache to serve requests and that is where I'm having trouble.I've been following this guide:https://ift.tt/2Ae3cn5 PM2, configuring Apache, etc. So now when you visit my website, you see a Apache file directory with the heading 'Index of /' and it is the /public directory familiar to all of you who use Express. So the root directory is the right directory. But it isn't starting the Node script. I don't know what could be wrong. Node isn't starting and running its script to set up the Express application.If anyone can ask me a few leading questions from a 'been there, done that' perspective, that would be brilliant and very helpful. I'm kind of stuck here.

ap-npm: private authenticated npm repository

Hello everyone,About 1,5 year ago I started programming and almost immediately was fortunate enough to get a position at a small software company. In my time there I worked on a private npm repository as at the time the only available solution was Verdaccio (which has improved a lot since), but Verdaccio did not offer functionality for using your own authentication provider. ap-npm is written in Typescript and provides interfaces for AuthProviders and StorageProviders. By default it uses a json database for authentication and the filesystem for storing packages. It is highly recommended you at least implement your own authentication provider.Development stalled last year due to personal reasons, but I am proud to announce that this package is (finally) ready to be used. It is supposed to be used with npm-scopes, but can also proxy install and audit requests if enabled in the config. It does not cache packages like Verdaccio does, but this could be added in the future (pull requests are welcome).This is my first time publishing anything open source so any feedback is welcome :)Repository: https://ift.tt/2AbSWvE MIT

Testing/Mocking request headers for Lambda function

I have a simple node app that will eventually become a Lambda function, used by API Gateway on AWS.In the real world Lambda/API Gateway usage, the request will be forwarding headers with authorization token to the Lambda function which it will need to authorize.So I am trying to understand the best way to mock this in local development as stand alone node app that will be easily transferable to Lambda function, and in turn, test the passing of this authorization to the stand alone node app.I've thought about using Express in the local version, but I'm not sure I want to go to that length or if there is a simpler way I can mock the request header to get my local dev going?

Server cannot parse the same cookies it issues.

Hello, I am running an express app that uses the out the box stack (cookie-parser, connect-session, etc). I am also using a i18n module that sets a cookie depending on the user's language. I am having a cookie issue where I am not sure whether I am sending the correct cookies, or if the server is having problems parsing them. Whenever I authenticate a user, it sends a cookie that looks like this"language=en-US; Path=/, keystone.uid=s%3A5b4f9dc45e23fe02b4b24862%3ACzrzXyYInv7VKl5PaevC9Ynd1qJD72Ip%2BmCd7NynoxU.rGWyRaQecitVOH4vQpZTD1ThpvQ44BI%2BmzOF51kjSms; Max-Age=864; Path=/; Expires=Wed, 25 Jul 2018 19:07:02 GMT; HttpOnly, this.sid=s%3AappByhBNAo31t5RlBF9cd80lZcsQEjE3.o4Wq9o7bhpptCrcJt6XIh1jjKQgWPgibnoI8TDalkDk; Path=/; Expires=Thu, 25 Jul 2019 18:52:38 GMT; HttpOnly"Now inside my app (its a react native app), I store that string verbatim and whenever I try sending it again in the next request, my server cannot parse it, and only parses the language cookie. I've taken that same cookie and tried sending it through fiddler, and postman and it has the same problem. The only way I am able to successfully recall my session is if I only send"this.sid=s%3AappByhBNAo31t5RlBF9cd80lZcsQEjE3.o4Wq9o7bhpptCrcJt6XIh1jjKQgWPgibnoI8TDalkDk;"in the cookie.So upon further testing I decided to download the Cookie parser module to test it individually and it indeed parses the entire cookie wrong. Anyone know whether that cookie string is really invalid to send back to the server? If it is, what can I modify to make it valid? I may have to end up writing a regex to extract the this.sid token and I am not really good with regular expressions so help with that will also be very much appreciated. Thanks

Parsing and inserting records in the correct order with Tedious and Promises

I have a parsing application that connects to machines via TCP and waits for data to be sent from them. Once data is sent, I have to parse the messages to organize things correctly for the SQL table. Currently, machines may send multi-line messages that each have a four-component payload, or they may send a single-line message with the four-component payload.It is currently imperative to insert records in the correct order for later automation tasks that run against the database. Unfortunately, when a multi-line message comes in and is parsed, the records are frequently inserted in a random order. Is there some queuing function I could introduce to make sure things are inserted serially?A pared down example of my code is as follows:Collecting the data:clients[i].on('data', function(data) { console.log("Data: " + data + " " + hosts[j]); parse_message(data, hosts[j][1], hosts[j][2]); }); Parsing the strings and payload components:function parse_message(data, m_id, type) { //console.log('Message received = ' + data); var msg = data.toString('utf8'); // Convert from object class, split CRs var strings = msg.split('\r\n'); // split multi-line data console.log("Strings: " + strings) strings.forEach(function(element) { var payload = element.split("///"); // split by separator if (payload.length == 4) { // If array is properly formed payload[3] = payload[3].trim(); if (payload[3].includes('N')) { payload[3] = payload[3].slice(1, payload[3].length); } payload[4] = m_id; // Send machine ID payload[5] = dt.getDateTime(); if (type == 'Machine') { Insert_Machine(payload); } else if (type == 'Pallet') { Insert_Pallet(payload); } else { console.log("Type didn't come through. Where am I supposed to put this?") } } }); } Inserting with Tedious and Promises:function Insert_Machine(msg, callback) { var result = []; var deferred = q.defer(); // init promise var connection = new Connection(machine_config); connection.on('connect', function(err) { var request = new Request( // set up request structure 'INSERT INTO dbo.Data_new (pp_id, d_No, d_Note, d_Data, d_seq, d_machine, d_DateTime) OUTPUT INSERTED.Id VALUES (@pp_id, @d_No, @d_Note, @d_Data, 0, @d_machine, @d_DateTime);', function(err, rowCount) { if (err) { console.log(err); // print error on console if anything happens } else { console.log(rowCount + ' rows inserted to Machine_Data: ' + msg); // confirm the insert } deferred.resolve(result); // resolve promise }); request.on('row', function(columns){ result.push(columns); }); request.addParameter('pp_id', TYPES.NVarChar, msg[0]); request.addParameter('d_No', TYPES.NVarChar, msg[1]); request.addParameter('d_Note', TYPES.NVarChar, msg[2]); request.addParameter('d_Data', TYPES.NVarChar, msg[3]); request.addParameter('d_machine', TYPES.NVarChar, msg[4]); request.addParameter('d_DateTime', TYPES.NVarChar, msg[5]); // Execute SQL statement connection.execSql(request); } ); return deferred.promise; }

NodeJS 10: A Power Packed Features to Look out!

Node.js – an open source platform for fast and scalable network applications. As we all know the impressive introduction of Node.jsIt never lacks updated versions. Using an event-driven and non-blocking model, the platform proves as the super fast to make the lightweight and efficient real-time applications. The broadly used server-side platform is developed on the Javascript V8 engine of Chrome. NodeJS is quite a helping tool for building the most intensive web applications. It can be of live video streaming or maybe SPAs(single page applications)Currently, the Node JS is quite in the discussion of the technocrats because of the power packed features it has. The latest version Nodejs 10.0 is now official and becoming the long-term support in October 2018. Being in the prominent business of serving the latest mobile application development projects and technologies, we would like to share some informative content here regarding the power packed features of the newest NodeJs version. Let’s see the difference this newbie is making with our mobile applications and what’s exciting on the bucket list for the Node.js developers as well as the users.Revamped N-APIN-API bring some of the important changes in execution with the release of NodeJS 10.0 and those are quite impressive. First of all, the N-API is no more in an experimental model. It is officially supported by the API layer. This will help in establishing the stability in the framework as well as the quality contribution to the project development phases. This will give a strong support to the back-end applications. This new update is almost about to reduce the cost of developing native modules and hence automating the system of reusability of codes. N-API’s official version is all set to reduce the intensity while updating so the framework can seamlessly process the deployment. Easier to upgrade and accessible at easy steps. JS ImprovementsThe all-new NodeJS10 is set to bring so many JavaScript language improvements. It includes the prototype.toString() for returning the exact portions of the source code in text and reducing the vulnerabilities for keeping things confidential as much as possible. Performance BoostAlong with the extremely good improvements on bug fixing and error handling in performance, the NodeJS 10 is setting up the standards for boosting the performance through the V8 engine. It includes the async generator and array to keep things ahead. The NodeJS 10 update also increases the visibility in the code to overcome the performance issues. This visibility in the code can be maintained using the trace events. npm V6Node Package Manager is updated from the previous v5.7 to v6.0. Here the Node’s latest update will ship with the update with no more delay but on the prompt basis. This will impact positively on the improvements in all the areas such as performance and stability. Upgrading to the OpenSSL VersionThe latest NodeJS 10 is coupled with the cryptographic support to enable the highly anticipated cipher and authenticators. Ranging from TLS 1.3 to the upcoming LTS in October is a completely supported software platform in terms of meeting standards.

However, for a node service which could get getting lots of requests a second, it seems like deeply copying an object to make changes could have performance implications. Any thoughts on this practice server side?Ex:const thing = getThing (); thing.other.deep.prop = 'mutated'; Vs.const thing = getThing (); const newThing = { ...thing, other: { ...thing.other, deep: { ...thing.other.deep, prop: 'not mutated' }, }, };

Small app vs large app

Hi, I started learning node 2 months ago and I can build some apps using it. My question basically is what is the main difference between a large app and a small app except for the number of functions. Suppose I have a very simple, one page todo app - the user is able to save and delete todos which are stored in a DB (no user authentication). Then from the other hand i have a large app were users are able to log in, edit their profile, submit posts, comment, like etc. Is there any difference in the way that both apps are written? Does the bigger one require some more advanced concepts?Thanks in advance ;)

I already have done some project in node at my university and i want to dig a little deeper now. However I have one question i haven't found answered yet... Can you use node like php, to entirely create dynamic webpages serverside?What i mean, PHP gets interpreted on the server to generate pure html, so you can use loops, conditions etc. to generate your html without the need to alter it on the client side (I'm thinking about stuff like blog entries and so on...)Basically, is it possible to develop a website in node without the need to do "dynamic" stuff with js on the client side?Thanks in advance :)

Automating dependency management updates

With the introduction of package-lock, a new challenge arise - developers have to manually update dependencies and according to what I see - many rarely do that.Seems like the dependency management process should be automated - once a package versioning meets some rules (e.g. a month past since latest release) a PR should be generated with a newer version. I noted few commercial tools that do this, like greenkeeper.ui, but I prefer to stick to a community/free solution for a start. Do you have any solution in mind?

Data control using policies, validation, sanitization etc

I have been working on a project called fission for some time now. Originally I built the library as a part of a very loosely scoped, discovery project for a client and programmed it using PHP. I needed some way of controlling incoming JSON objects and filtering out values which either were not what I expected or were not permitted according the requesting user's roles and scope. I needed this to happen on quite complicated sets of data with fields containing multiple layers of nested and repeated objects. After moving to nodejs a couple of years ago I built this library into my first published NPM library. I found this library to be incredibly useful for the work with microservices I am currently doing and wanted to gather feedback from others.If you work with JSON requests or with formatting the output of NoSQL databases (works for relational DBs as well) and want to filter data based on scope and roles then you might find use for this!https://ift.tt/2Nwe8hA

Local network game lobby

I am building an Electron-based game that uses Socket.io for local multiplayer (not connecting to an Internet-based server). I am having trouble setting up the client connection to the host. Because the socket.io server is local, not on the internet, I can't predict the IP address for it. From thinking about it, I have two options:Tell the host their IP address, then provide it to the client.Have the client scan the local network for the game being hosted.I'm not quite sure how to do either of these, and I'm honestly not picky. I looked very briefly at the node docs for os, but I didn't see a reliable way to get the correct network IP address. I also saw a way somewhere to scan a network for open ports, but I'm not sure if my game will be the only thing using that port or not, so I'm not sure if I should set up some kind of response to ping against that won't trigger socket.io.I realize this is kind of a niche case, but does anyone have a good place to start on either of these methods? I'm really not picky, I just want to get this going so I can start testing the host/client interaction. Thank you in advance!

We are currently using a MEAN stack. In the test environment, it ran fast. But after we launched, users are having trouble logging in and load times are super long even with a few users.Is this normal? What can I do with AWS to fix the issue?Any advice would help.

Need help serving up sites from a website builder!

We are using react.js, node.js, and postgreSQL.I am currently in a web development bootcamp, and we are working on our final group projects. My group is working on a simpler clone of launchaco.com and working on building reusable components to build custom websites has been going great. The problem we are having is how to automate the process of serving up websites either on a sub-domain of our domain, or allowing the user to purchase a domain through the google domain api, and then serve up their website, using surge or some other tech. Has anyone done this/seen it done? Or can anyone push us to a resource that will help us learn how to do this?Your help is very much appreciated!

Cluster module isn't working

I don't know if i just messed something up or if the module is actually broken.I'm using Node version 8.11.3. I'm following a tutorial and i literally copied over the same code. Yet the results are different.Here's the code:const cluster = require('cluster'); // Check that the current instance is Master if (cluster.isMaster) { // Cluster Manager / Master cluster.fork(); cluster.fork(); cluster.fork(); cluster.fork(); } else { // Child / Worker const express = require('express'); const app = express(); function doWork(duration) { const start = Date.now(); while(Date.now() - start < duration) { } } app.get("/", (req, res) => { doWork(5000); res.send("This was slow"); }); app.get("/fast", (req, res) => { res.send("This was fast"); }); const port = 3000; app.listen(port, () => { console.log((`Server started on port ${port}`)); }); }When i test in browser, i fire up the root route and then the "fast" route. The fast route should load instantly because of clustering, and after 5 seconds the root route should load. But it doesn't happen. Both routes load simultaneously after 5 seconds. I'm at a loss.

Beginner's Question About NPM

I've been using NPM (well using as in copy-pasting commands to install packages), and I'm actually trying to learn how to properly use it now.I noticed that even when I installed packages locally, they weren't appearing in my project directory (i.e - no node_modules folder was being created in the local directory). As such, I did some investigating and I saw I had a node_modules directory underneathC:\Users\myusernameI also saw a .babel.json and package-lock.json file in that same directory.I looked inside, and saw all packages that I had installed "locally" were actually appearing there.Is that normal, or is my npm installation messed up? I feel like it's incorrect - since it's probably the reason why when I install a package locally, no node_modules directory is created in the local project folder, but I'm not sure.

How to get value from a promise used from a module?

Hii!I'm having a problem.I've used Axios to get a data from an external API, Axios basically uses a promise to make a request to other website, then handle the data.It goes in this fashionaxios.get(API_URL) .then((data)=>{code}) .catch((error)=>{more code}) If I want to console.log the received data, from INSIDE the "then" in the axios promise, it shows me the right data fetched from the api.but If I do:let request = ('./request.js') //the code with the axios request would go here let data = request.get(API_url) console.log(data);what I get is "[object promise]" not the data.wrapping the call in async/await is not working, it gives me the same results: [object Promise].What do? (yes, I've already looked in stackOverflow haha)Thanks!

How would you attack a node.js application?

As part of a blog post that I'm writing on Node security, I'm trying to think how would an attacker knowing that the application is created with Node trying to exploit the system ("If you can’t think like an attacker, you can’t think like a defender...")?I'm focused only on the node characteristics that might help the attacker, not generic web application weakness like try DDOS, try inject SQL, etcFor example, some idea - many Node developers let the process exit on error, so I'll try to provide many faulty JSON inputs with hope that one will trigger process exit. Once I find the right input, I can very easily generate a DOS conditionOther ideas?p.s. I'm not an attacker, if you want to see a draft of the blog post - just ask

React and Node app help.

I am making a web site and choosing React and node as the stack. I have worked on both separately but now I want to use both of them together. I want to make api's with node and consume them with react. And also I have never used react on production (i.e. never used npm run build or whatever that command is). I can't figure out how routing will be done. Will react router handle that for me or I should specify routes in index.js?P.S. It's mostly a static site with not much back-end intensive stuff so routing is my main concern.

First day at job.

Sorry for my bad English. It was my day at job as Software developer. I'm told to build a dashboard to show analytics of an existing software. The stack is React, Node, MySQL. Now I've worked quite a bit with React and know enough Node to build a basic CRUD application with MongoDB and mongoose. But they want me to use MySQL and knex.js.I hadn't heard of knex.js until today. They want me to follow the structure of an existing project that they've built using the same technologies. And they admit that they have not followed best practices and there are many workarounds to things they couldn't find an optimal solution for.Now, how should I start learning knex with node and mysql and get up and running with best practices that are followed in the market. Can you please point me to the right direction?

Java has been the primary language I've used along with doing a bit of full stack.I've been doing a lot of node lately for side projects (for work and at home) and I enjoy it so much more than generic Java programming.How many of you have transitioned into a NodeJs role after already having a good paying career in another technology? I'm looking around at jobs and I'm about 90% certain that I would have to take a pay cut to get into node more.

pm2 cluster mode with express EADDRINUSE

I'm trying to run a node app using pm2. The app by default runs on port 2345, I've changed the config to so it runs in cluster mode and 'instances' is set to max which at the moment only launches 2 instances. As soon as I start the app and both instances of the app launch, one keeps restarting until it does so 15 times at which point it errors out. Looking at the log it complains that"Error: listen EADDRINUSE :::2345"How can I run the app in cluster mode w/o it crashing? Everything I found online points to running the app on a single port and the cluster manages everything. I'd rather have this scale up/down depending on the server resources rather than having to manually edit the config and run X number of apps in fork mode all on different ports.

Express error - cannot find module

I've got through to halfway through chapter 4, but when I swapped from the single default controller to the two new ones instructed by the book, I've started getting the following error every time I try and run it:PS C:\Users\james\node\loc8r> node . module.js:549 throw err; ^ Error: Cannot find module 'C:\Users\james\node\loc8r' at Function.Module._resolveFilename (module.js:547:15) at Function.Module._load (module.js:474:25) at Function.Module.runMain (module.js:693:10) at startup (bootstrap_node.js:191:16) at bootstrap_node.js:612:3 The files I've modified are:/loc8r/app_server/routes/index.jsvar express = require('express'); var router = express.Router(); var controllerLocations = require('../controllers/locations'); var controllerOthers = require('../controllers/others'); /* Locations category controller */ router.get('/', controllerLocations.homelist); router.get('/locations', controllerLocations.locationInfo); router.get('/locations/review/new', controllerLocations.addNew); /* Others category controller */ router.get('/about', controllerOthers.about); module.exports = router; /loc8r/app_server/controllers/locations.js/* GET homepage */ module.exports.homelist = function(req, res) { res.render('index', {title: 'Home'}); }; /* GET Location info */ module.exports.locationInfo = function(req, res) { res.render('index', {title: 'Location info'}); }; /* GET add review page */ module.exports.addNew = function(req, res) { res.render('index', {title: 'Add a review'}); }; /loc8r/app_server/controllers/others.js/* GET about page */ module.exports.about = function(req, res) { res.render('index', {'title': 'About Loc8r'}); }; I'm aware that this folder structure isn't how things are done by default but it's the way the book recommends it be done for neatness. It worked fine with the default route and with the default route split into a route and a controller, but not since. I'm sure it's an obvious mistake but I've searched and can't find any answer. VS Code doesn't highlight any formatting errors so I've given up hope it's something glaring for me to fix like that.Node is v8.11.3, NPM is v5.6.0, Express is v 4.6.13 according to npm listCould someone also advise how I'd go about following back through the error message to work out where I've gone wrong?Many thanks,James

What is the standard way to store runtime settings?

I currently develop an app that consists of 3 separate packages for now and they all share the same database (it's MySQL).Now I want to give user an ability to toggle some features on/off using some interface (I believe it doesn't matter, it could be web page with form, REST endpoint, etc) so my app should be able to save this setting somewhere and retrieve it when needed.What is the best way to do this?The most obvious way for me was using of JSON file but I don't think that it's a right way because my app may have hundreds of settings and I think that I should use database for this because it's application data after all.I came with idea to use settings table where I have text key and JSON value. JSON because MySQL supports it natively and settings may have different type of values. Then I can have some wrapper class that will fetch all settings from database and reload them when something changes (so I don't have to do DB requests when I need to check some setting).Is it OK?
