// Using function middleware format
const minify = require('@neutrinojs/babel-minify');

// Use with default options

// Usage showing overriding minification options
neutrino.use(minify, {
  minify: {},
  plugin: {}
// Using object or array middleware format

// Use with default options
module.exports = {
  use: ['@neutrinojs/babel-minify']

// Usage showing overriding minification options
module.exports = {
  use: [
    ['@neutrinojs/babel-minify', {
      minify: {},
      plugin: {}

The minify and plugin properties map to the options defined by babel-minify-webpack-plugin.
