Usage

Rolldown

// rolldown.config.js
import removePropTypes from 'rolldown-react-remove-prop-types';

export default {
  plugins: [
    removePropTypes({
      mode: 'remove', // default
    }),
  ],
};

Rollup

// rollup.config.js
import removePropTypes from 'rolldown-react-remove-prop-types/rollup';

export default {
  plugins: [
    removePropTypes({
      mode: 'remove', // default
    }),
  ],
};

Options

mode

• 'remove' (default): Completely removes propTypes definitions
• 'wrap': Wraps propTypes with process.env.NODE_ENV !== "production" ? {...} : {}
• 'unsafe-wrap': Wraps with if (process.env.NODE_ENV !== "production") {...}

removePropTypes({ mode: 'remove' })

removeImport

• true: Remove PropTypes imports when mode is 'remove'
• false (default): Keep imports

removePropTypes({
  mode: 'remove',
  removeImport: true,
})

include / exclude

Standard Rollup filter patterns.

removePropTypes({
  include: 'src/**/*.{js,jsx,ts,tsx}',
  exclude: 'node_modules/**',
})

ignoreFilenames

Array of patterns to ignore. Creates a RegExp with patterns joined by |.

removePropTypes({
  ignoreFilenames: ['node_modules'],
})

additionalLibraries

Additional PropTypes-like libraries to remove.

removePropTypes({
  additionalLibraries: ['react-immutable-proptypes'],
})

classNameMatchers

Custom class names to treat as React components.

removePropTypes({
  classNameMatchers: ['BaseComponent'],
})

Example Transformations

Input

const Baz = (props) => <div {...props} />;

Baz.propTypes = {
  className: PropTypes.string
};

Output (mode: 'remove')

const Baz = (props) => <div {...props} />;

With Comment Annotation

Force removal with comment:

Component.propTypes /* remove-proptypes */ = {}
