"Typescript modules: the definition of 'defined' has not been found

Can anyone shed some light on TypeScript 1.8 modules for me, please?

So, I have a file named SomeClass.ts:

export class SomeClass {

}

Now, in my app.ts, I'm importing SomeClass:

import {SomeClass} from "./SomeClass";
var xxx = new SomeClass();

After building the app with both AMD and CommonJS module systems and targeting ES5, I encounter errors like "define is not defined" or "require is not defined" when opening it in a browser.

Do I need to install additional libraries for this to function properly?

Answer №1

To configure the module system, set it to "amd". Visit requirejs to download the necessary files for your project.

<script data-main="scripts/app" src="scripts/require.js"></script>

Take note of the data-main attribute which specifies the path and module name, such as "app" in your case. Requirejs will handle the fetching of your module, so there's no need to include it in another script tag.

Answer №2

Do I need to add any extra libraries for this to function properly?

Absolutely. However, you have the option to package the library along with your project effortlessly. For example, utilize commonjs (enables seamless use of npm) and then compile with webpack.
