I've been researching for long time but haven't found what I need. Maybe here someone can help me out.
What I want:
I'm trying to create an application that will run inside electron. Both frontend and backend should be encapsulated within a single executable, so I was thinking React js and Nodejs would be a good option.
But it's not as simple as I thought. Found a good boilerplace for reactjs https://github.com/electron-react-boilerplate/electron-react-boilerplate but I have no idea how I could encapsulate nodejs as a backend to it.
It'd also somehow would need to be integrated with the release package and so on...
Additionally I'd need to have a webserver that will run on localhost:[port] when you launch the application.
Technical Summary:
So basically:
Electron with React js - as the application 'face'
Nodejs - as the backend of the application
Webserver running locally - (using react js).
In the application, I would put link to the pages that is served by that locally running reactjs web app.
Hope I was clear. And I really hope someone can help me out.
Thanks!!!
as you know the serverside part is separate from front end.you can lunch react electron together like this article https://flaviocopes.com/react-electron/ .but serverside must start to stand alone . you could use pm2 for launching them.http://pm2.keymetrics.io/
lets talk about electron. what is electron?
according to electronjs.org :
Electron is an open source library developed by GitHub for building
cross-platform desktop applications with HTML, CSS, and JavaScript.
Electron accomplishes this by combining Chromium and Node.js into a
single runtime and apps can be packaged for Mac, Windows, and Linux.
so the electron is a tool for creating desktop applications.it uses chromium engine for accessing resources of the operating system level. but the intention of that is creating apps not a serverside job.
if you have some needs and logics that must handle in a server you should be considering that. otherwise, read about serverless applications.

This may be a dumb question, but is the default react app (created using npm create-react-app my-app) using node.js? I am confused because in my web development class at university, I had to download node.js to create react applications. However, I didn't have to do anything like creating a server or initiating a node.js file, which is described in w3school's node.js tutorial. Because of this, I found out that I don't even really know what node is used for, besides downloading packages like redux and whatnot.
create-react-app uses node.js for all of its dev tooling. Likewise, a lot of the tools you'll use in the React ecosystem (like webpack, prettier, npm), all run on top of node.js as well).
You'll most probably build your react app to a static file, in which case the production output will not require node.js, it will be html and javascript assets that can be served directly to a client.
Hope that helps! Let me know if you have other specific questions
Node.js is used for server-side while React.js is for the front-end part. So, no, you don't need Node.js.
Under development mode, yes. Create react app runs NodeJs with Webpack Dev Server to allow you get feedback when modifing files, start or stop the server.
I discovered ionic this week and I'm really considering using it at work.
Basically, my goal is to build an app that will work on android and Ios, where the needed functionality is to connect to the cloud over web socket and pull data from the cloud and show it on my phone. Maybe later I'll eventually need to consider using login but not for now at least.
Normally, if I'm building a web app. I ll use nodejs to pull the data from the cloud and expose it to the frontend. I ll write all code together and I ll host my app in Heroku or something where the entry point is my nodejs server right? So that my server needs to start and it will take care of the rest.
This is a bit confusing in ionic since I need to start the app with ionic serve, but somehow I also need to start my nodejs server too right? So I assume I can't write the server-side code inside the ionic app or am I wrong?
There is not much about this on the internet but I did some research and I guess that I should deploy (host) my nodejs server in the cloud (maybe using Heroku) and then connect to the server from my mobile app over the socket. Is this the right/only way to do this? are there any security issues with this method?
I find ionic great but I'm not sure if I should use it at work. Sincerely, this use case of using a backend server with ionic made me confused.
Ionic looks ideal for building cross-platform apps that does not need server-side scripting, but how complex can it be if I want to integrate some server-side code in my app? especially as I said I'm going to use some login forms in the future to extend the functionality of my app.
PS: I'm using ionic 6.10.1 and specifically I'm interested in using ionic with react not with angular.
After some search, I discovered that it isn't possible to deploy the frontend and backend code together. Therefore the trick is to deploy the nodejs server separate from the frontend.
Precisely, if it is a web app, then you should deploy the nodejs server in a separate host from the frontend. Then by starting the frontend app, you can communicate with the running nodejs server via socket or REST API.
Hope this helps someone in the future :)
I suffer a lot in the past with angular apps and social media, so I'm glad to see that Angular Universal is being developed.
Currently I have some apps that are Angular4 as front end, and Java with Spring as backend. As far as I know there are some ways to implement Angular Universal here but they seem pretty complex (at least is what I read). So I want to know if that is in that way or not...
But anyway, my main question here, is because I saw that in order to implement Angular Universal we should have (ideally) to make the backend with nodejs, how to structure these two technologies, I mean... Should I have Angular app as a frontend app and Nodejs app as a totally different backend app (just like Java) where both are connected with web services? Or should I served Angular4 SPA direcly from Nodejs views?
And where should I place Angular Universal here?
Now that Angular CLI v1.6 is out, there's native support for building Angular Universal into your projects easily using Node.js! Essentially, you would ng build --prod to create a dist/ folder, and then create a simple node back-end and connect to your dist/ folder containing your front-end code. This article gives a great step-by-step guide: Angular server-side rendering in Node with Express Universal Engine.
When you use Angular Universal, it is going to be a single process (Operating system process) that hosts and serves your Angular pages.
In production you may have multiple such processes behind a load-balancer.
Your back-end APIs (if developed in Javascript) may be hosted in the same Node server or in separate server.
The Angular Universal setup steps are detailed here in the official documentation.
However, I had a few wasted hours to find out the following point
Webpack 3 is not compatible with ts-loader versions higher than 3.5.0. At the time of developing this, the latest version of Angular CLI is 1.7.2 which uses Webpack 3.*. Hence, while setting up Angular Universal, install ts-config#3.5.0
Finally, here I have a seed project for Angular Universal. It uses Vagrant to locally setup the development environment. Also, by tweaking an environment variable in your local host machine, you can run it in a production mode in a Docker container. The steps to run it are detailed in the readme file.
If you refer to my Dockerfile in the above Github link, its entrypoint reads:
ENTRYPOINT ["pm2-runtime","start","/home/aus/dist/server.js"]
So, you see, it's just a singe command, and your app is up and running at port 4000. Of course you can use other command line parameters to provide memory limit, port and so on.
My understanding is that AngularJS including Angular2 is a client-side framework, while Node.JS is a server side platform. They should not cross. But all Angular2 tutorials I found use Node/NPM. Why is that?
Because npm is a package manager for packages written in JavaScript, and JavaScript can run both on client and server side. In other words, frontend and backend applications can both benefit from packages. Many development tools also use node as an underlying process (e.g. Jest-cli).
I would suggest you to use angular2 only on client side. The performance of angular2 really shines when it comes to handling view containers over regular server side codes. On the NodeJS side, I would recommend using es6 features. Which has revolutionised how you can not only code, but also performance.
The reason you see most tutorials using npm is because they are either using TypeScript or a build tool that uses Node to convert to ES5 or build your project.
However you can still build Angular2 apps using the sfx version (self-executing bundle) of Angular2 and using ES5 syntaxes without having to use node or npm. Here is a blog post that shows how to do that
http://blog.thoughtram.io/angular/2015/05/09/writing-angular-2-code-in-es5.html
Angular2 is a front-end framework but a lot of tooling that assists in building Angular2 applications are available via NPM.
If you want a package manager that's geared specifically to front-end development I suggest JSPM. It supports front-end modules of various formats (ie AMD, CommonJS, UMD), handles transpiling out of the box, and can be used as a build tool to concatenate/minify your application code.
You'll still need NPM for many other utilities and you'll need a back-end server for testing (I recommend live-server).
As far as the back-end is concerned. One of the Angular2 dev teams is working on a Node/Express extension that supports isomorphic rendering of JS. In short, it pre-renders the view on the server so the user can interact with it in the browser while the app loads in the background. The start time of launching a fully-featured SPA will still be kind of slow (relatively) but perceived speed will be instantaneous.
I am going to create my first angular application. I have read lots of angular tutorial and many of them mentioned node.js.I am really got confused here.
Do we really need to install node.js and other dependencies to run angular application ?
Can't I just add respective angular libraries in my eclipse and create Angular application?
What are advantages of using node.js?
Also it is necessary to add all angular code is under App folder?

As it is said on note.js website
Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
So it depends if you want to have server logic (services) or not. If you are creating just the UI of the app you don't need note.js. Also Angular is NOT dependable on note.js
