# Third-party notices

Original lesson and application code: Copyright 2026 Chason Arthur / Zyel, MIT.

React and React DOM 19.3.1: MIT; their bundled notice is retained beside app.mjs. TypeScript 7.0.2: Apache-2.0; esbuild 0.28.2: MIT. These are development dependencies where applicable. Locked versions are supplied in the source packages.

Go 1.27.3's WebAssembly support: Go BSD-style license, retained beside wasm_exec.js where applicable. Go source: https://go.dev/dl/. This original example uses the Go standard library.

The optional PHP component exercise uses Laravel Illuminate Database and Events 13.38.0 (MIT) and their locked dependencies; Composer fetches their original license files during installation. Third-party dependencies are not relicensed by the application MIT file.

The browser PHP worker contains GPL-2.0-or-later PHP.wasm wrapper/runtime components from WordPress Playground 3.1.62. Its compiled worker is distributed under those applicable GPL terms; the original application source remains available under MIT as well. The PHP interpreter has its own PHP license; see upstream source notices. The exact upstream repository source, build scripts and license notices are retained at:
