I have defined the following Angular2 component:
import {Component} from 'angular2/core';
@Component({
selector: 'my-app',
moduleId: module.id,
templateUrl: './app.component.html'
})
export class AppComponent {
}
When I try to compile this, I get the following error on line 5:
src/app/app.component.ts(5,13): error TS2304: Cannot find name 'module'.
I believe module.id is referring to the CommonJS module variable (see here). I have specified the CommonJS module system in tsconfig.json:
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"declaration": false,
"removeComments": true,
"noLib": false,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"sourceMap": true,
"pretty": true,
"allowUnreachableCode": false,
"allowUnusedLabels": false,
"noImplicitAny": true,
"noImplicitReturns": true,
"noImplicitUseStrict": false,
"noFallthroughCasesInSwitch": true
},
"exclude": [
"node_modules",
"dist",
"typings/browser.d.ts",
"typings/browser",
"src"
],
"compileOnSave": false
}
How can I correct the TypeScript error?
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"
}
