I created a mobile application with flutter in front end and back end with node.js but I want it to use node js in offline mode in another meaning I want host this node inside the mobile. can I?
No.
First, you'd need NodeJS itself built for you mobile platform. Only then can you even consider running the node application you've written.
Flutter is Dart and NodeJS is well, JS. You can't put them together. But if you are building a node app that builds into a static js and html, may be you can put it in a webview, which does not seem to be the case here.
You are asking to run server side code on the client itself and offline too. If the application can really be offline, I think you're better off without a backend and store everything static within the flutter app itself.

I'm new to web servers in nodejs and i'd like to know if there is possible to have an electron like node integration in a web server (to be able to use nodejs in index.js script file linked to index.html)
Thx for all :)
It's not possible. Browsers control the way that client side JavaScript is executed, so it's just technically impossible to connect both runtimes in any way that works on client machine, you'd need a customized browser, which is what Electron basically is. And neither should you want to - if the runtimes were connected in that way, any user could execute arbitrary commands on your 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'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.
So I just started learning ReactJS and React Native.
I have some knowledge of MEN (Mongo, Express, Node). Up to this point, I learned how to res.render() files and pass objects in there.
Now what I need to do, is make MERN app. This app also needs to have Android and iOS version of it.
So far I learned that R stands for ReactJS, not react-native. Is there a way so it includes both? And where do I put react files when I have folder structure like from express-generator? Or is there a way they can be in completely different directories, and one calls the other via import?
It comes down to architecture I believe. The way I like to create the stack goes as follows.
You can create an API using Mongo/Express/Node that serves endpoints for your client app (created using reactjs, react-native and whatever other tech you want to include) to call using HTML requests. This would work for both mobile apps (using react-native) and desktop apps (using reactjs).
There's a couple different ways to deploy this. You can create 2 separate apps, a server app and a client app, which are both hosted individually by 2 separate hosts. This is useful because you decouple your front end code from your back end code. Also, you can have 2 separate directories for your code.
Another method of deployment would be to have your server serve your client files. This ones a little bit tricker, but you will be able to deploy your entire app inside 1 host so this option is also cheaper. I would suggest reading this article to figure out how to implement this and the file structure https://originmaster.com/running-create-react-app-and-express-crae-on-heroku-c39a39fe7851
As we all know you can use compilers as Cordova to convert web applications so you can upload your application to the app store.
This can easily be done when developing with HTML5 and Node.
But is it possible to convert a MEAN application (MongoDB, Express, Angular and Node)?
You can run nodejs server on mobile with jxcore, but I think you should run only client side part on cordova and api shall stay on server. Ideally, I think that api and client side must be separate projects.
No, you can't.
MEAN stack is full stack. You can make your frontend an app with cordova but you still need database and backend service.
But that's ok. Make your app mobile friendly and stick with your server to provide the data you need to make it work.
What you can do, it's to create hosted web app. This is existing web application, just wrapped to make it possible to submit to app store.
For this you can use Manfoldjs, for example Using Cordova Plugins in Hosted Web Apps or if you use Visual Studio, you can use Visual Studio Tools
for Apache Cordova.
