leetbundle

A simple bundler for your TypeScript libraries.

Leetbundle is inspired greatly by microbundle, but leetbundle has different goals that are much more tailored towards library developers such as proprietary TypeScript support and opinionated architecture to make your projects easy for everyone to understand.

Why?

We all probably understand the pains that we must go through to be able to just setup a TypeScript package for Node.js. Leetbundle abstracts out that process to a simple CLI and allows you to include the locations to the files of interest within your package.json to easily scaffold out your large-scale package.

Getting Started

First, install leetbundle via the following command:

npm install -g leetbundle

After that, create a package.json in your project with the following content:

{
  "name": "foo",
  "source": "src/index.ts",
  "types": "dist/types/index.d.ts",
  "main": "dist/index.js",
  "exports": "./dist/index.modern.js",
  "module": "dist/index.module.js",
  "unpkg": "dist/index.umd.js",
  "scripts": {
    "build": "leetbundle build",
    "dev": "leetbundle dev"
  }
}

Now, you can create a TypeScript file with the same location as the source key defined in the json file above and export some content like the following:

export const foo: string = "asdf";

Finally, you can run npm run build or npm run dev and your TypeScript module will be turned into a UMD, CommonJS, and ESM within milliseconds. You can also check out your type definitions in dist/types.
