Liberator

A stubornly opiniated environment for typescript libraries.

Using Liberator, you get:

• Typescript.
• A clean dist/ containing only what users of the library need.
• Multiple build targets: esm, cjs, umd, prod, dev.
• Test and coverage of both the source and the various built libraries.
• Linting with eslint and prettier.
• A clean repository without a bazillion config files.

Getting started

Here's the very few rules of thumb you need to keep in mind:

1. All the source code goes in src/.
2. src/index.ts is the sole entrypoint.
3. Specs and tests can be either in src/ or tests/
4. You do not publish the root repository, the dist/ directory itself is published.
5. *.spec.ts runs on both the source and the built library.

From scracth:

npx @probedjs/liberator my-library
// or
npx @probedjs/liberator @my-scope/my-library

For an existing library

The easiest way to go about this is to create a placeholder library using npx @probedjs/liberator placeholderLib, and use it as a reference point.

Make sure you don't forget to set "private": true in your package.json so that you don't accidentally publish the source version of the library.

Configuring

For the time being, there is no configuration options whatsoever, since the main reason for it existing is to unify configuration accross a bunch of projects. That being said, if there is a demand for it, we can make things a bit more parametrizable.

Building

The following command will populate the dist/ directory with the library ready to be published.

npm run build

Testing

Testing the source. This will run all files named *.test.ts as well as *.spec.ts on the library as present in the src/ directory:

npm run test

Testing the built library. This will run all files named *.spec.ts on all versions of the library present in the dist/ directory:

npm run testDist

Misc.

Keeping Visual Studio Code happy

If you are using the eslint VSCode extension, you need to point it in the right direction:

.vscode/settings.json

{
    "eslint.options": {
        "configFile" : "node_modules/@probedjs/eslint-config/index.js"
    }
}
