What This Skill Covers
- Use the WebSockets API to communicate in real time with your Cloudflare Workers.
- Main sections:
Tags,Write a WebSocket Server,Connect to the WebSocket server from a client,Write a WebSocket client,WebSocket close behavior.
Workflow
- Open the most relevant file under
docs/for the exact documented workflow and wording. - Open
schemas/files for exact structured contracts. - Open
examples/files for concrete requests, commands, snippets, and manifests. - Do not add behavior or configuration that is not present in the attached source files.
