Event Iterator (SSE)

oRPC provides built-in support for streaming responses, real-time updates, and server-sent events (SSE) without any extra configuration.

Overview

const example = os
  .handler(async function* ({ input, lastEventId }) {
    while (true) {
      yield { message: 'Hello, world!' }
      await new Promise(resolve => setTimeout(resolve, 1000))
    }
  })
