options

configPath

Type: string

Path to a rollup config, the config can be a javascript object or a function that accepts an object of configParams and return an object.

// ./rollup.config.js

module.exports = {
  input: './entry.js',
  output: {
    format: 'umd',
    file: 'bundle.js',
  }
};

configParams

Type: object

An object that will be passed to the config function in case it is actually a function. Useful when you want to build your rollup config dynamically using cli arguments or configuration from the preset.

// ./preset.js

rollup({ configPath: './rollup.config.function', configParams: { entry: './index.js'}});

// ./rollup.config.function.js

module.exports = configParams => ({
  input: configParams.entry,
  output: {
    format: 'umd',
    file: 'bundle.js',
  }
});

or something like

// ./preset.js

rollup({
  configPath: './rollup.config.function',
  configParams: {
    entries: {
      app1: './index1.js',
      app2: './index2.js',
    },
    debug: false,
    srcDir: './src',
    distDir: './dist'
  },
});

// ./rollup.config.function.js

module.exports = ({ debug, entries, srcDir, distDir }) => Object.keys(entries).map(entryName => ({
  input: path.join(srcDir, entries[entryName]),
  plugins: [
    ...debug ? [] : [uglify()]
  ],
  output: {
    format: 'umd',
    file: path.join(distDir, `${entryName}.bundle${debug ? '' : '.min'}.js`),
  }
});
