TypeScript error in Angular2 code: Cannot find name 'module'

Question

I have defined the following Angular2 component:

import {Component} from \'angular2/core\';

@Component({
  selector: \'my-app\',
  moduleId: module.id,
  te         


        

Answer 1

For those looking to do this with Typescript 2.x and @types, here's what you need to do:

1. npm install -D @types/node
2. Include types: ["node"] under compilerOptions in your tsconfig.json file.

I had a tough time finding the instructions for step 2.

Reference: Typescript issue 9184

Edit:

You could also do:

2. Include "typeRoots": [ "node_modules/@types" ] under compilerOptions in your tsconfig.json file. This is instead of the types property and has the benefit of automatically including any @types you install with npm.

For example:

{
  "compilerOptions": {
    "typeRoots": [
      "node_modules/@types"
    ]
  }
}

[Second edit] Apparently, with the latest typescript, you only need typeRoots or types if tsconfig.json is not in the root of your project or your types are not stored in node_modules/@types.
