Server¶

Pyplet’s server runtime is built on top of Tornado and lives in the pyplet.server package:

• pyplet.server.web wires the HTTP routes, static assets, WebSocket endpoints and application shell.
• pyplet.server.config exposes configuration values such as address, port, apps root and the Pyodide URL.

The pyplet start CLI command configures pyplet.server.config (via command-line flags and PYPLET_* environment variables) and then starts the Tornado application defined in pyplet.server.web.

At a high level:

• The home page lists micro apps discovered under the configured apps root.
• Each app is served via a dedicated route that loads Pyodide, fetches the app bundle, and calls pyplet.client.bootstrap.
• WebSocket endpoints expose a minimal async API compatible with pyplet.WebSocket, allowing apps to implement websocket_server_loop coroutines for real-time communication.

Refer to the CLI and Micro Apps pages for details on configuration and app structure.
