A basic roll up config file that allows for typescript and dynamic external dependencies

.rollup.config.js

import typescript from 'rollup-plugin-typescript2'
import pkg from './package.json'

const dependencies = Object.keys(pkg.dependencies || {});
const peerDependencies = Object.keys(pkg.peerDependencies || {});
const external = [...dependencies, ...peerDependencies];

export default {
  input: 'src/index.ts',
  output: [
    {
      file: pkg.main,
      format: 'cjs',
      exports: 'named',
      sourcemap: true,
    },
    {
      file: pkg.module,
      format: 'es',
      exports: 'named',
      sourcemap: true,
    }
  ],
  plugins: [
    typescript({
      rollupCommonJSResolveHack: true,
      clean: true
    }),
  ],
  external,
}
