Description

Provides a local runtime for JavaScript and WebAssembly worker code modeled on Cloudflare Workers infrastructure. It is useful for testing serverless applications, edge-style request handling, and worker behavior outside production.

This runtime executes code and may expose local services, files, or network behavior depending on configuration. Developers should treat untrusted worker code carefully and separate test environments from production secrets.
