ESM Package (with Hybrid CommonJS support)

Concept for publishing an NPM ESM package (with CommonJS backward):

• Create an ESModule package (in ./src) {type:"module"}
• On publish use Babel to transpile (in ./lib) -> Also add {"type":"commonjs"} on ./lib/package.json file.
• use ./node_modules/.bin on script to avoid using global on another environment.
• Store only ./src on dit (./lib and ./node_modules are useless)
• Before Publishing, transpile the package (Root-Project's Babel who'll use commonjs version of this package will not bundle dependencies)

Note

• script transpile:js is probably useless (but in case we need to provide a minimify version ?)
