Encountering an error in TypeScript and ng2 rc.1: Error message (20, 15) TS2304 indicates that the name 'module' cannot be found

Having trouble with TypeScript and ng2 rc.1 - getting Error:(20, 15) TS2304: Cannot find name 'module'.

I encountered this issue when trying to use a directive of the module in my code:

@Component({
    selector: 'Notes1',
    moduleId: module.id,
    directives: [ModalDialog, FORM_DIRECTIVES, DisplayError],
    templateUrl: 'Notes1.html',
    styleUrls: ['Notes1.css']
})

Any suggestions on how to resolve this TypeScript error? Everything seems to be working fine during runtime.

Thanks,

Sean

Answer №1

The issue arises from the TypeScript compiler not recognizing the module identifier. To resolve this quickly, you can add the following declaration:

declare var require: any;

To ensure a more comprehensive solution, you can refer to a definition provided in the DefinitelyTyped/node repository:

interface NodeRequireFunction {
    (id: string): any;
}

interface NodeRequire extends NodeRequireFunction {
    resolve(id:string): string;
    cache: any;
    extensions: any;
    main: any;
}

declare var require: NodeRequire;

interface NodeModule {
    exports: any;
    require: NodeRequireFunction;
    id: string;
    filename: string;
    loaded: boolean;
    parent: any;
    children: any[];
}

declare var module: NodeModule;

Answer №2

To resolve this issue, I successfully resolved it by appending "Id" after module in the tsconfig file as follows: "moduleId": "commonjs". This simple adjustment eliminated the error entirely!

Feel free to give it a try, Alex
