Usage

neutrino-middleware-compile-loader can be consumed from the Neutrino API, middleware, or presets. Require this package and plug it into Neutrino:

// Using function middleware format
 
const compile = require('neutrino-middleware-compile-loader');
 
neutrino.use(compile, {
  include: [],
  exclude: [],
  babel: {}
});
// Using object or array middleware format
 
module.exports = {
  use: [
    ['neutrino-middleware-compile-loader', {
      include: [],
      exclude: [],
      babel: {}
    }]
  ]
};
  • include should be an array of paths to include in the compilation. Maps to Webpack's Rule.include
  • exclude should be an array of paths to exclude from the compilation. Maps to Webpack's Rule.exclude
  • babel is a Babel configuration object, consumed by babel-loader. Use this to set properties such as presets, plugins, and env.

Merging Babel Configuration

This package also exposes a function for merging Babel configurations. This comes from the babel-merge package.

const { merge } = require('neutrino-middleware-compile-loader');
 
const together = merge(
  {
    presets: [
      ['babel-preset-env', {
        targets: {
          browsers: ['latest 1 Chrome']
        }
      }]
    ]
  },
  {
    presets: [
      ['babel-preset-env', {
        targets: {
          browsers: ['latest 1 Firefox']
        }
      }]
    ]
  }
);
 
console.log(together);
 
// Logs:
{
  presets: [
    ['babel-preset-env', {
      targets: {
        browsers: [
          'latest 1 Chrome',
          'latest 1 Firefox'
        ]
      }
    }]
  ]
}
