Angular 2 do we need typings.jons file if we use TypeScript 2.0

Question

I saw examples for angular 2 which use typings.json:

{
  "globalDependencies": {
    "core-js": "registry:dt/core-js#0.0.0+20160725163759",
    "node": "registry:dt/node#6.0.0+20160831021119"
}

for installing necessary typescript files for certain packages.

Start from TypeScript 2.0 we can do it trough npm with '@types/...':

"devDependencies": {
    "@types/es6-shim": "0.31.32",
    "@types/node": "6.0.52"
  }

From my perspective second approach is more clear.

1) Can someone explain it in more detail, how to use, what is the difference ?

2) People also use script in npm to install typings:":

"scripts": {
  "postinstall": "typings install",
}

Is it necessary to use it for second approach if we put everything in npm packages, is "npm install" enough ?

No you don't need the typings.json or typings if you are installing type definitions from @types/.
