@wyw-in-js/rollup

The package contains WyW-in-JS plugin for Rollup. Supports Rollup v1, v2, v3, and v4.

Installation

# npm
npm i -D @wyw-in-js/rollup
# yarn
yarn add --dev @wyw-in-js/rollup
# pnpm
pnpm add -D @wyw-in-js/rollup
# bun
bun add -d @wyw-in-js/rollup

Usage

After installation, add the plugin to your rollup.config.js:

import wyw from '@wyw-in-js/rollup';

export default {
  plugins: [
    wyw({
      sourceMap: process.env.NODE_ENV !== 'production',
    }),
  ],
};

Concurrency (tsdown/rolldown)

Some Rollup-compatible bundlers may execute plugin hooks concurrently (e.g. tsdown/rolldown). To keep evaluation deterministic, @wyw-in-js/rollup serializes transform() calls by default.

To opt out, pass:

wyw({
  serializeTransform: false,
});

Disabling vendor prefixing

Stylis adds vendor-prefixed CSS by default. To disable it (and reduce CSS size), pass prefixer: false:

wyw({
  prefixer: false,
});

To get details about supported options by the plugin, please check documentation.
