Angular - ng serve vs npm start

Question

I have a little question about angular-cli.

Is it true that when I run ng serve I use the global installed angular-cli and when I run npm start the local one?

Answer 1

When you run the npm start internally it will call whatever command is written inside the start in the package.json.

"scripts": {
  "start": "ng serve"
}

it will run the ng serve

For more details, check When to use 'npm start' and when to use 'ng serve'?

Answer 2

Command will decide by package.json . ng serve / npm start is used based on package.json can change form there. if ng serve is not working can use npm start to run server.

ng server :

"scripts": { "ng": "ng", "start": "ng serve", "test": "ng test",....... }

Answer 3

Yes it is true.

Let's say your global Angular CLI version is 2 and you just cloned and installed a project from github that is created with Angular CLI version 1. If you run ng serve it will execute using version 2 (which is your global cli), if you run npm run start it will use the script in node_modules/.bin folder (which is local to your project and which is the right one for the job).
