Elegant, typed, and simple toolkit to implement cross-platform WebSocket servers.

👉 [📖 documentation](https://crossws.h3.dev)

## Features

🧩 Seamlessly integrates with [Bun](https://crossws.h3.dev/adapters/bun), [Cloudflare Workers](https://crossws.h3.dev/adapters/cloudflare), [Deno](https://crossws.h3.dev/adapters/deno) and [Node.js](https://crossws.h3.dev/adapters/node) and any compatible web framework.

✅ Prebundled with [ws](https://github.com/websockets/ws) for Node.js support with alternative/much faster [uWebSockets](https://crossws.h3.dev/adapters/node#uwebsockets) adapter.

📦 Extremely lightweight and tree-shakable conditional ESM exports.

🚀 High-performance and simple hooks API, without per-connection callback creation.

🌟 Typed hooks API and developer-friendly object inspection.

[^1]: crossws supports Node.js via [npm:ws](https://github.com/websockets/ws) (prebundled) or [uWebSockets.js](https://github.com/uNetworking/uWebSockets.js).

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.
