"Setting up SystemJS to properly load TypeScript modules within a folder: A Step-by-Step

When working with Typescript, you have the option to create a folder with an index.ts file in it. This allows you to load the module simply by specifying the folder name. For instance:

src/
  index.ts
  ..

you can use import * from './src'; to import the contents.

However, there is a challenge when using this approach with SystemJS (such as in Angular 2). SystemJS will search for src.js within the src folder. How can I configure SystemJS to look for either src.js or src/index.js instead?

Answer №1

In order for the transpiled js file to be correctly located within the same folder as its corresponding ts file (located in the "/src" folder in your particular scenario), it is essential to inform systemjs to recognize js as the default extension.

SystemJS.config({
        packages: {
            '/src': {
                defaultExtension: 'js'
            }
        }
    });

    SystemJS.import("/src/index.js");
