I want to run multiple NodeJs versions on a single system.
For EX:- I have two nodejs apps. One app are running nodejs version 10.xx.xx and another one is running nodejs version 12.xx.xx.
here I want to move both apps on a single server.
how is it possible..??
Package each app using Docker Container then each app will have his own nodeJS version without issues because of the isolation.
You'll find official nodeJS continer in here https://hub.docker.com/_/node/

Is it possible to develop the node SDK part of a Hyperledger Fabric project with a microservice Nodejs project or with a simple Nodejs project?
It is better to at least start the development of a Node.js project as something that can run from the command line line. Fixing errors and viewing log output will be easier. I presume that for a microservice, you will run it as a docker container which will listen on some port for activity. All of this can be done first as a standalone Node.js project. Once developed and tested, just create the docker image and then run it.
I have been using api.ai javascript SDK on angular to build my chat app to integrate it with the website. As this javascript sfk is deprecated I am now exploring to build the same on Node JS SDK with socket.io for real-time experience and angular for client features...
Currently, I'm following the below link to build my chat app

As I am very new to Node I have lots of doubt like...
How to deploy my node and angular app on a server to host it on my website
Angular and node can it be deployed as a simple app.. if so what are the steps and how could I achieve it.
Is node is possible ti have multi threading as many users might chat with my chatbot in parallel before on angular it will be acheived by session id.. but how it is possible on the node?
Is it fine to deploy my node app on my existing apache server or should I use separate server
How can I host multiple node js chat app on a single server since each app will use a port... how much it is possible...
Which server is recommended for node deployment windows ubuntu or Linux.
Please help me...
Angular Apps are static files that can be served using any server. For NodeJS, you will need a server that supports NodeJS runtime execution environment. A simple cloud server will do. (AWS or others that you may prefer)
Angular runs on the client-side, NodeJS runs on the server-side, there is no "Simple App Deployment" (as far as I've known). You need to run the NodeJS server code which will server the REST API, and send the Angular deployment files to the client with some file server. (Even the NodeJS server can do it)
"Node.js is a single threaded language which in background uses multiple threads to execute asynchronous code" [Source]
But you can use "fork" to run parallel tasks. For chatbot, you may consider using WebSockets.
It is possible to run NodeJS with Apache server, but how you want to deploy it depends on your decision and architecture. See HERE for more information.
Link in no. 4 should have answer this this.
NodeJS can be deployed on both Windows and Linux(Ubuntu) environment. It depends on how much you can spend, and how much benefit that expenditure will bring you. (Linux server operating systems are totally free, Windows servers aren't)
Have a Node.Js API and a React app semi finished. Working on deploying to get the development cycle churning. Currently using npm start for viewing the react server during development. Same for the Node API. When deployed to AWS EC2 I am building in the most basic fashion, npm build pushing to a 'release' folder.
Once the deploy folder is up, I can go into it and run serve -s release
This gets me up and running. I can do the same for api server.
To get the apps running as a service, for the api, I can see how I can build a systemd process and run that with no issue.
For the react app, is there an easy way to run that server as a system... I'm new to this stack, so I might be confused. I have read in some places that once you've built your react app that you need to serve it out via apache or nginx? (e.g. in development it hosts itself, in production, you need to serve it) Is that sort of the general idea - build with local hosting, deploy with a production webhost?
Help appreciated. This is my last major issue before I can get Jenkins running a nice pipeline for deployment. Thanks!
Since you are already running a NodeJs server, It would be a good idea to host your ReactJs App in the NodeJs App itself.
You can pipline in the Jenkins to Build the ReactJs App first and the move it to static serving folder in the server and then you just need to deploy the NodeJs app in which ever environment that you want.
I have created a node.js rest api created using express framework for routing. I have used tutorial
Now I want to deploy that rest api on actual production server. How to achieve that thing.
I have gone through below links.
Deploy node js application with express framework on production mode --- Only for linux. I need for windows.
Deploying NodeJs Express Rest API to Windows 10 IoT -- a little bit similar problem but no solution
https://stackoverflow.com/a/38652869/2810015 -- this said to run npm start on production server after copying all of the files on server. But this is not working fine either.
Any help will be highly useful.
You use pm2?
Usually I use it to start the application. It works for both windows and linux. He leaves the service initated, and in case something happens that knocks the service up again.
You install it on the server, and instead of using it
node server.js
You use the command below
pm2 server.js start

We are running a nodejs application, but we want to run different version of same application, how we can achieve this, like python virtual environment.
I have seen nodeenv, but from the examples, it seems it only provides different versions of node binary to run, but not nodejs application.
With regards,

When you have different versions of the same app, I assume that you will have a different package.json file for each version of the app? And you probably have the different version of the app resides on different folder?
Are you in a Linux environment or windows or Mac?
Can you use a .sh/bat to invoke the npm start on different folders ?
