Datastar Racket SDK🔗ℹ

Datastar is a lightweight framework for building everything from simple sites to real-time collaborative web applications.

The Racket SDK for Datastar provides server-side helpers for reading signals from requests and sending SSE events, as well as client-side helpers for generating Datastar attributes and action expressions.

This reference is organized into three parts:

• HTTP — Read datastar signals from incoming HTTP requests and send SSE or one-shot responses.

• Sugar — Generate Datastar data-* attributes and action expressions for x-expressions.

• Testing — Test handlers with mock SSE generators and parsed event values.
