js-packaging

Test different JavaScript modules and packaging for node and the browser.

Level 0: Common-JS, No Transpilation

This is the most straight-forward scenario: no transpilation needed, everything basically self-contained. Functions (or classes) are exported via module.exports.

Using the package is possible from ES style modules (i.e. type set to module using import) when importing the default export and destructuring afterwards to a const.

Level 1: ES Modules

This use-case simply transfers the level 0 use-case over to use ES modules. The most significant changes are that the JavaScript files now end with .mjs and the package.json configures type to be module. Functions (or classes) are exported via export/export default (examples are omitted here).

Level 2: Single Package, Common-JS & ES Module
