I want to use 5000 instead of 4200.
I have tried to create a file on root name ember-cli and put JSON according to the code below:
ember-cli
{ &q
goto this file
node_modules\@angular-devkit\build-angular\src\dev-server\schema.json
and search port
"port": { "type": "number", "description": "Port to listen on.", "default": 4200 },
change default value whatever you want and restart the server
