Is there any way to host the same Angular app on two different hosts (different IP or different port) using Node.js?
The .angular-cli.json file allows you to specify Angular-CLI configuration options; including the default hostname and port.
serve: Properties to be passed to the serve command
• port (number): The port the application will be served on. Default is 4200.
• host (string): The host the application will be served on. Default is localhost.
You can define the used port in the .angular-cli.json file by defining the property like this:
{
"defaults": {
"serve": {
"port": 2500
}
}
}
See the Angular CLI documentation for more info and a complete listing of configuration options:
https://github.com/angular/angular-cli/wiki/angular-cli
Command line solution
If you're looking for a command line solution that does not require and configuration editing, simply run the ng serve or ng serve --prod commands with the optional host and port commands.
ng serve --host 0.0.0.0 --port 4201
Using these optional command line parameters, you can simply run the command twice, each with different a host and port.
Side note:
That being said, unless you are going to be serving your Angular application using the Angular CLI, you'll likely need to configure these options using the methods associated with your hosting platform.

I run my app to my local machine via ssl like this:
ng serve --ssl --host: 0.0.0.0
so it is up at: https://localhost:4200
I also using my ipv4 adress which is: XXX.XXX.XX.XXX to make my requests to the server via my services, so i make my api calls like this: https://XXX.XXX.XX.XXX:80/api...
In my back end, I have created an https server so my API calls are been made via https
Everything works great to my desktop
Problem is: The app wont cast to ther devices.. it wont even load and
after some time i get the msg this site cannot be reached
The built in webpack server that is used for ng serve is not meant for production or sharing to other computers, it is only supposed to work on local for development because of security reasons. You should consider hosting a compiled version with a separate web server such as nginx. If you absolutely NEED the built in webpack one to work, you can force it to bind to all of your IP addresses with this:
ng serve --host 0.0.0.0
You may need to disable the host check as well:
ng serve --host 0.0.0.0 --disable-host-check
You can access this, but you might need to turn off your Firewall, this mostly happens in windows machines.
Try turning it off and accessing the IP from other machine.
I'm trying to understand what needs to be done to put my react app online.
Until now, I launched it on my mac using npm start, and accessing localhost:3000 or http://127.0.0.1:3000.
So I currently have bought a small server, installed everything (last version of node and npm, git and other necessary things), cloned my repo, and installed all dependencies.
When I do npm start on the server, it says it's available on port 3000. But when I go in my server's ip with the following :3000, it times out.
I don't really understand what need to be done to do this, I found some things about configuring apache on the server, others about using pm2 so have a node script running even after leaving the terminal, but that would be my next step I guess.. And other about configuring things with express (but do I need node+ express here ? As it's a simple front end react page ?).
if you are using webpack devserver, use it for development only
The tools in this guide are only meant for development, please avoid using them in production!
back to your question, there is a difference between binding to 127.0.0.1 or binding to 0.0.0.0
try changing the devserver to listen to 0.0.0.0
webpack.config.js
module.exports = {
//...
devServer: {
host: '0.0.0.0'
}
};
Usage via the CLI
webpack-dev-server --host 0.0.0.0
also note, that you will need to allow ingress rules (incoming connections). that is, allow a request from the internet to reach your server
There are a lot of configurations you will have to do when you deploy your application on a server. Building the app, Nginx, pm2 and even ssl certification. This video is 20min and has all you need. https://www.youtube.com/watch?v=oykl1Ih9pMg&t=1s
I have a react app served with HTTPS (I need it for a service worker running in the background)
that is having CORS issues with my backend running locally with Firebase Functions.
Firebase Functions is just wrapping an express application with CORS module enabled.
I performed a few tests with OPTIONS calls to this backend and I'm getting the proper headers.
They problem is that my Frontend (HTTPS) cannot reach out to my backend (HTTP).
Is there any way to run firebase functions locally with HTTPS instead of HTTP?
running firebase serve --help only shows
Options:
-p, --port <port> the port on which to listen (default: 5000) (default: 5000)
-o, --host <host> the host on which to listen (default: localhost) (default: "localhost")
--only <targets> only serve specified targets (valid targets are: hosting, functions, database, firestore)
--except <targets> serve all except specified targets (valid targets are: hosting, functions)
-h, --help output usage information
The local emulator does not support HTTPS at this time. T here is a thread on GitHub about this, with advice to use ngrok for a similar use case. https://github.com/firebase/firebase-tools/issues
You can do it with native react-scripts:
REACT_APP_ENV=development yarn start
package.json:
"scripts": {
"start": "HTTPS=true sh -ac '. .env.${REACT_APP_ENV}; react-scripts start'",
...
See create-react-app docs.
I'm a newbie so sorry if this is a stupid question.
I was trying to setup this a-frame boilerplate code.
https://github.com/aframevr/aframe-boilerplate
This is the instructions given.
To serve the site from a simple Node development server:
npm start Then launch the site from your favourite browser:
http://localhost:3000/
This works as expected, but the webcam is restricted because the site is http and not https. I want to know how to serve this as https instead?
Furthermore I am confused on what actually happens when you do npm start.
The start script is budo --live --verbose --port 3000 --open.
But the project doesn't have any js files that could be the server. Only the html file in the front end. What actually happens with npm start?
npm start runs:
"start": "budo --live --verbose --port 3000 --open",
running budo starts the server
--live enables LiveReload on HTML/CSS/JS file changes
--verbose enables debug messages
--port defines the port
--open launches the browser once connected
by default it uses index.html which is in the main directory
If you want to create a https server instead of http you need to add one more option:
--ssl, -S create an HTTPS server instead of HTTP
If you see some unknown commands run, always try to find the documentation and search the keywords (like HTTPS).
I am creating one application that needs to be made on staging server from one point. Because creating it on local is impossible as it has some endpoints that other servers in network has to access.
I have created an application in Vue.js and Laravel. In local, I used to run npm run hot so that I don't have to re-compile when I change some code. But as I have to continue developing this application on a live server, I want to run npm run hot on a custom domain like staging.something.com instead of localhost:8080.
I don't have any issue if somehow localhost:8080 co-operates but when I run npm run hot on a live server, Here is the error I get when I try to access the web application.
GET http://localhost:8080//js/app.js net::ERR_CONNECTION_REFUSED
I think it should show IP address of my server instead of localhost. I don't know what's wrong with this but it's not working.
Laravel mix uses the webpack-dev-server package for the run hot command.
webpack-dev-server has a switch --useLocalIp which will make it use the servers local IP address.
It also has a --host switch which can be used to set the IP address manually --host 0.0.0.0
