byteguard

Encodes JS bundles into a binary format for casual source code protection.

Not encryption, not DRM — it raises the cost of reading a shipped bundle from open the file to reverse-engineer the loader. Anything the runtime executes is still recoverable by a determined attacker.

Packages

Package	Role
byteguard	Bundler-agnostic core — encoder, loader generation, algorithms
vite-plugin-byteguard	Vite adapter

The core has no vite or rollup imports, so other bundler adapters can be added without touching it.

Usage

// vite.config.ts
import byteguard from 'vite-plugin-byteguard'

export default {
  plugins: [
    byteguard({
      algorithm: 'xor',   // or 'aes-gcm'
      exclude: ['**/worker-*.js']
    })
  ]
}

See packages/vite-plugin-byteguard for the full option list.
