byteguard

Encodes JS bundles into a binary format for casual source code protection. Bundler-agnostic core — no vite or rollup imports.

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.

Most users want the adapter instead:

• vite-plugin-byteguard

Use this package directly only when writing an adapter for another bundler.

API

import { encode, generateLoader } from 'byteguard'

// Encode a bundle into the binary container
const { data, key } = encode(source, 'xor', 32)

// Generate the inline loader that fetches, decodes and runs it
const loader = generateLoader('assets/index.bin', 'xor', true)

| Export | Purpose | | --- | --- | | encode | Source → binary container (BGRD magic, versioned header) | | generateLoader | Minimal inline browser loader for an encoded file | | xorEncode / aesEncode | Algorithms | | MAGIC VERSION ALG_XOR ALG_AES_GCM | Container constants |

Algorithms: xor (default) and aes-gcm.
