Angular 2 dependencies

Question

Please consider this dependencies in package.json:

"dependencies": {
                  "@angular/common": "2.2.1",
                  "@angular/compiler": "2.2.1",
                  "@angular/core": "2.2.1",
                  "@angular/forms": "2.2.1",
                  "@angular/http": "2.2.1",
                  "@angular/platform-browser": "2.2.1",
                  "@angular/platform-browser-dynamic": "2.2.1",
                  "@angular/router": "3.2.1",
                  "@angular/upgrade": "2.2.1"
                }

I want to use the bundle version of Angulajs and when I run this command:

npm install angular

It installs angular.min.js I want to know what is the difference between Those? Is there any way to bundle dependencies using npm and create a single file?

Another question is I know that Angular 4 has been released and when I run this command:

npm install angular

It installs angular.min.js with version v1.6.4 so what is this file? And why it outdated?

Answer 1

When you run npm install angular, AngularJS (v1.x) is installed.
Which is why, when you run the command, the latest stable version of AngularJS i.e v1.6.4 is installed.
Note: Angular v1 (AngularJS) is still supported. Last stable release was 3 months ago.

Angular 2 and above versions are simply called Angular.
Note: Angular(v2 or v4) is an incompatible rewrite of AngularJS(v1)

Now the question is you should choose either of the above according to requirements. The steps you have followed is to get AngularJS(v1).
You can have a look at Angular Quickstart to get started with Angular2+ which is now updated to v4.4.5 (as of 5th July 2017).
You can have a look at Package.json and you would notice,

"dependencies": {
  "@angular/common": "~4.0.0",
  "@angular/compiler": "~4.0.0",
  "@angular/core": "~4.0.0",
  "@angular/forms": "~4.0.0",
  "@angular/http": "~4.0.0",
  "@angular/platform-browser": "~4.0.0",
  "@angular/platform-browser-dynamic": "~4.0.0",
  "@angular/router": "~4.0.0",

  "angular-in-memory-web-api": "~0.3.0",
  "systemjs": "0.19.40",
  "core-js": "^2.4.1",
  "rxjs": "5.0.1",
  "zone.js": "^0.8.4"

},
which should install current stable version of Angular
