2.0 Rewrite 🎉

Complete rewrite of JS-Confuser using Babel! 🎉

⚠️ Breaking changes

Note

Check out the Migration guide on how to properly update from 1.X to 2.0. The obfuscation upgrades in 2.0 are worth the small refactoring.

• Revamped API Interface

• • JSConfuser.obfuscate() resolves to an object

Property	Type	Description
code	string	The obfuscated code.

• Renamed Stack to Variable Masking

• Added configurable limits to options:

const options = {
  target: "node",

  rgf: {
    value: 0.5, // = 50% of eligible functions
    limit: 10 // Maximum of 10 changes for performance reasons
  },

  // Original format is still valid (No limit applied)
  rgf: 0.5
}
