index.js doesn't quite match the functionality of index.ts

Question

index.js doesn't quite match the functionality of index.ts

Currently, I'm in the process of developing a web application using angular2 and typescript. I attempted to incorporate index.ts so that in my code, I could simply include

import {LayoutComponent} from '../layout';

However, during transpilation, the JavaScript engine does not search for index.js but instead looks for ./layout, causing it to fail.

Is there a configuration setting for the typescript transpiler that needs adjustment, or perhaps a systemjs configuration that needs tweaking? Would using another loader like webpack be a viable solution?

The root of the issue has been identified. TypeScript relies on nodejs module resolution, which is detailed here: http://www.typescriptlang.org/docs/handbook/module-resolution.html

However, systemjs does not follow the same resolution process as nodejs. To ensure compatibility with systemjs module resolution, I will need to use ./layout/index or set up map entries for each module. On the other hand, commonjs leverages nodejs resolution, so I plan to transpile my code to commonjs and work with webpack instead.

Indeed, the systemjs must be properly set up:

Ensure your index.html file includes something like this:

  System.config({
    packages: {
      src: {
        format: 'register',
        defaultExtension: 'js'
      }
    }
  });
    System.import('src/dist/boot') --- specify your root file path
        .then(null, console.error.bind(console));
