Features

• Target file filtering (see include & exclude)
• Capture stripped shebang (see capture option)
• Sourcemap support (see sourcemap option)

Options

include / exclude

minimatch pattern to be used as filter, see createFilter documentation.

syntax

include: Array<string | RegExp> | string | RegExp | null;
exclude: Array<string | RegExp> | string | RegExp | null;

capture

You can pass a capture function or object to get the stripped shebang in case you need it later.

function

syntax

capture: (shebang: string) => void;

example

let shebang;
...
  plugins: [
    strip({
      capture(capturedShebang) {
        shebang = capturedShebang;
      },
    }),
  ]
...
console.log(shebang);

object

syntax

capture: Object;

example

let capture = {};
...
  plugins: [
    strip({
      capture,
    }),
  ]
...
console.log(capture.shebang);

sourcemap

You can pass sourcemap: false to speed things up a bit if you don't need source maps. Anything other than false will default to true.

syntax

sourcemap: boolean = true;

example

...
  output: {
    file: "bin/lib.js",
    sourcemap: false,
  },
  plugins: [
    strip({
      sourcemap: false,
    }),
  ]
...

⚠️ Note that you will get a warning if you set rollup to generate source maps and set this to false.
