Build real-time features without the headaches of WebSockets. Our SDK provides end-to-end type safety from schema definition to client interactions.
export const channels = sock8.channels({
'chat.{roomId}.messages': sock8.channels.rich({
schema: z.object({
message: z.string(),
sender: z.string(),
timestamp: z.number(),
}),
capabilities: {
history: true,
presence: z.object({
typing: z.boolean(),
online: z.boolean(),
}),
},
}),
});TypeScript catches errors at compile time
// TypeScript catches errors
channels.chat.messages.for({ wrongParam: '123' })
// Error: Property 'wrongParam' does not exist.
// Expected property 'roomId' of type string.
channels.chat.messages.for({ roomId: '123' })
// ✓ Type check passedEverything you need to build modern real-time applications with type safety at the core.
Create dynamic, scoped channels with path parameters. Perfect for multi-tenant apps and user-specific streams.
Track who's online, typing status, cursor positions, and more with just a few lines of code. Create truly collaborative experiences.
function Document() {
const { self, others, update } = usePresence(channel);
useEffect(() => {
// Update presence when cursor moves
window.addEventListener('mousemove', (e) => {
update({ cursor: { x: e.clientX, y: e.clientY } });
});
}, []);
}Access recent messages on channel join with our built-in history capability. No need to implement separate storage or manage message caching.
// Access message history with a single hook
const { history } = useHistory(channel);
// Messages available immediately on joinIntegrate with your existing auth system. Grant access to specific channels based on user identity and permissions with fine-grained control.
