AWS Lambda¶

Hayate supports API Gateway HTTP API payload v2 and Lambda Function URLs through a native event adapter.

Buffered responses¶

Use the normal Lambda adapter for JSON, HTML, binary responses, cookies, and ordinary buffered streaming bodies.

Native response streaming¶

When time-to-first-byte matters, Hayate also provides a custom Runtime API path for Lambda response streaming. It writes the Lambda streaming prelude, metadata, body chunks, and terminal framing directly instead of claiming that the ordinary buffered handler streams.

This path has core CI evidence but is not yet part of the production golden application's deployment flow. Treat that distinction as an adoption input.

See the core runtime guide for adapter APIs and limits.
