Is it possible to reorganize the JavaScript modules created by the TypeScript compiler?

In my TypeScript project, the structure resembles that of a typical Maven Java project. Here is an overview of how the project is organized:

*.js file for commonjs/webpack, system, and amd.

  • For commonjs/webpack, I utilize tsc with tsconfig.json and then use webpack along with webpack.config.js to generate the consolidated file, bundle.js.
  • For system module, I directly use the gulp-typescript task with the module set to system to create the single file, lib-system.js.
  • For amd module, again I employ gulp-typescript with the module set to amd to generate the single file, lib-amd.js.

However, when I load these single *.js files into the browser (utilizing <script> tags with webpack and SystemJS for the others), I observe that I have to initialize my objects as shown below:

var c = new car.Car('chevy', 'traverse', 2017);
var a = new animal.Animal('cat');

It bothers me that I have to repeat car.Car or animal.Animal in the code. Is there a way to achieve the following without modifying the project structure?

var c = new entity.Car('chevy', 'traverse', 2017);
var a = new entity.Animal('cat');

Creating a file, entity.ts, and defining both Car and Animal in that file is a solution, but it seems inefficient to have a long file with numerous classes just for logical grouping.

I tried merging all the *.ts files into one uber ts file, but encountered issues with imports and class hierarchy. Therefore, I am looking for a way to logically group my classes by function (e.g., entity, dao, validator) into modules instead of the default file-based grouping.

I have yet to find any tools that can facilitate this process and would appreciate any suggestions or solutions.

Answer №1

To address this issue, one approach is to develop a module for grouping called src/entity.ts, and re-export classes from it:

export { Car } from './entity/car';
export { Animal } from './entity/animal';

Another method is to utilize rollup.js, a tool that appears to have the ability to merge multiple compiled modules together. However, it is specifically designed for JavaScript, and I lack prior experience with it.
