Official JS modules for Edge Python exposing host APIs (DOM, network, storage and more) to Python scripts. Each capability is a plain ESM registered with createWorker via mainThreadModules, no .wasm, no Rust, no custom embedder.

├── dom
│   └── src
│       ├── index.js
│       └── main
├── network
│   └── src
│       ├── index.js
│       └── main
├── storage
│   └── src
│       ├── index.js
│       └── main
├── time
│   └── src
│       ├── index.js
│       └── main
└── tests

One folder per capability. Each ships a <name>/<name>.json corpus; the shared runner in tests/ walks for them and drives every case through headless Chromium.

<script type="module">
    import { createWorker } from "https://cdn.edgepython.com/runtime/src/index.js";
    import { dom } from "./dom/src/index.js";

    const worker = await createWorker({
        wasmUrl: "https://cdn.edgepython.com/compiler.wasm",
        mainThreadModules: { dom },
    });
    await worker.run(await (await fetch("./script.py")).text());
</script>

Requires Deno v2 and Playwright's Chromium.

# Lint one capability
cd host/<capability> && deno lint src/

# Install Chromium (once)
deno run -A npm:playwright install --with-deps chromium

# Test one capability (from host/)
cd host && HOSTCAP=<capability> deno test --allow-all tests/

<capability> is one of dom, network, storage, time.
