npm install babel-minify --save-dev

const minify = require("babel-minify");

const {code, map} = minify("input code", {
  mangle: {
    keepClassName: true
  }
});

minify input.js --out-file input.min.js --mangle.keepClassName

const minify = require("babel-minify");

minify(input, minifyOptions, overrides)

Refer babel-preset-minify options

• babel: Custom babel
• minifyPreset: Custom minify preset
