Static Assets Binding API

Read the binding reference before implementing calls. Check the configured binding name and use the project's existing environment types.

Task Documentation
Forward a request or fetch a specific asset Runtime API reference
Understand how binding requests apply HTML and fallback settings Binding fetch behavior and HTML handling
Run authorization or transform content before serving Run your Worker script first
Inspect default MIME, cache, and validation headers Default headers
Add or override response headers Custom headers and Worker-response caveat
Fetch assets imported by Vite Vite asset features

When selecting a different asset, construct a full URL using the incoming request as the base. Preserve the returned status and headers when transforming a response; do not collapse every unsuccessful response into an application 404.

See configuration.md for bindings and patterns.md for routing choices.
