rollup-plugin-preserve-shebangs

A Rollup plugin that preserves shebangs (#!/usr/bin/env node) in output files

Why?

Package executables (under bin in package.json) need shebang #!/usr/bin/env node at the top of the file.

With that line, rollup errors:

Error: Unexpected character '#'

This plugin removes the shebang before compilation, and restores it before writing the file.

Install

npm i -D rollup-plugin-preserve-shebangs
# or, with yarn
yarn add -D rollup-plugin-preserve-shebangs

Usage

// rollup.config.js

const { preserveShebangs } = require('rollup-plugin-preserve-shebangs');

module.exports = {
  // ...
  plugins: [
    // ...
    preserveShebangs(),
  ],
};
