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

I installed in the project, and worked well

npm install @types/node --save-dev

Answer 2

Instead of "ambient" try "global" by Typings 1.0

typings install dt~node --global --save

Answer 3

Update

If you use Typescript 2^ just use the following command:

npm i @types/node --save-dev

(instead of --save-dev you can just use shortcut -D)

or install it globally:

npm i @types/node --global

You can also specify typeRoots or types in your tsconfig.json if you want but by default all visible “@types” packages are included in your compilation.

Old version

You need to install node ambientDependencies. Typings.json

"ambientDependencies": {
    "node": "github:DefinitelyTyped/DefinitelyTyped/node/node.d.ts#138ad74b9e8e6c08af7633964962835add4c91e2",

Another way can use typings manager to install node definition file globally:

typings install dt~node --global --save-dev

Then your typings.json file will look like this:

"globalDependencies": {
  "node": "registry:dt/node#6.0.0+20160608110640"
}

Answer 4

Two key points:

1. Register typings by running typings install dt~node --global --save. So you'll get the following section in typings.json:

   "globalDependencies": {
       "node": "registry:dt/node#6.0.0+20160608110640"
   }
   

2. Add reference to the new module. Two ways:

   • Directly add a reference to a dependency in your TS

     /// <reference path="../../../typings/globals/node/index.d.ts" />

   • Add typings/index.d.ts in the files section of the tsconfig.json

     {
         "files": [
             "typings/index.d.ts"
         ]
     }

Answer 5

I use VS 2015, and had same issues, but I have resolved using:

1. add the typings.json file from the angular.io website (2.0.0 final at the moment) and the run:

   typings install // don't forget to install typings globally
   

then

npm install -D @types/node --save

in the package.json I have

"devDependencies": {
"@types/node": "6.0.40",
...

2. in the typings.json I have the following configuration

   {
   "compilerOptions": {
       "target": "es5",
       "module":"commonjs",
       "moduleResolution": "node",
       "sourceMap": true,
       "emitDecoratorMetadata": true,
       "experimentalDecorators": true,
       "removeComments": true,
       "noImplicitAny": true,
       "suppressImplicitAnyIndexErrors": true,
       "allowSyntheticDefaultImports": true,
       "types": []
   },
   "exclude": [
       "node_modules",
       "app-dist"
   ]
   }
   

I had to add the types as an empty array

3. check for duplicates, and if moduleId: module.id is still highlighted

p.s. to me personally is a strange issue, because as soon as you exclude typings inside typings.json, you have immediately highlighted 'module', but if you let it in, you have lot's of duplicates. Don't know who to blame, me, typescript or visual studio :)
