Quickstart

Sets up a composer pipeline with Babel middleware to transpile files from /src to /dist.

import babelMiddleware from 'ethical-composer-middleware-babel';
import { compose } from 'ethical-composer';

const composer = compose(
  babelMiddleware({
    babelOptions: {
      presets: ['@babel/preset-env']
    }
  })
);

composer.process('/src', '/dist').then(() => {
  console.log('Transpilation complete');
});
