Wakaru

Supported inputs

Every bundle format, transpiler, and minifier Wakaru understands.

Edit on GitHub

Bundlers

  • webpack 4/5
  • @vercel/ncc
  • Rollup / Vite scope-hoisted ESM output (heuristic)
  • esbuild and Bun
  • Metro (React Native)
  • Browserify, including Cocos Creator 2.x
  • Closure ModuleManager
  • SystemJS
  • AMD/UMD wrappers
  • Bun single-file executables

Two caveats:

  • Metro: plain JavaScript bundles only. RAM bundles and Hermes bytecode are not JavaScript and are out of scope.
  • ncc: CommonJS output is split structurally. .mjs output uses a top-level runtime and is not structurally split.

Transpilers

Helper and pattern recovery for output from:

  • Babel
  • TypeScript (tslib)
  • SWC
  • Closure Compiler

Minifiers

Artifact reversal for:

  • Terser
  • SWC
  • esbuild

Input kinds

  • A single .js file, or stdin
  • Multiple explicit files, such as an entry plus its chunks
  • A directory: with --unpack, Wakaru recursively scans .js, .mjs, and .cjs files, skipping hidden paths and node_modules
  • A Bun single-file executable, passed as an explicit path

Directory inputs work only with --unpack.

CLI
