@babel/register

On-the-fly ES6/ESNext compilation

Automatically compiles ES6/ESNext files when they are required. This allows you to use new JavaScript features without pre-compiling your code.

require('@babel/register');
require('./my-es6-script.js');

Custom Babel configurations

Allows you to specify custom Babel configurations, such as presets and plugins, to be applied when compiling your JavaScript files.

require('@babel/register')({
  presets: ['@babel/preset-env'],
  plugins: ['@babel/plugin-transform-runtime']
});
require('./my-custom-babel-config-script.js');

Ignore specific files or directories

Provides an option to ignore specific files or directories during the compilation process, which can improve performance by skipping unnecessary files.

require('@babel/register')({
  ignore: [/node_modules/]
});
require('./my-script.js');

Source map support

Supports inline source maps, which can be useful for debugging by allowing you to trace back to the original source code.

require('@babel/register')({
  sourceMaps: 'inline'
});
require('./my-script-with-source-maps.js');
