Get started

Install Server beside Core in the process that exposes your HTTP route.

pnpm add @anvia/server @anvia/core

Create the prompt request separately, then pass its events into the response helper:

import type { UIStreamRequest } from '@anvia/core/ui'
import { createEventStream } from '@anvia/server'
import { supportAgent } from './support-agent'

export async function POST(request: Request) {
  const body = (await request.json()) as UIStreamRequest
  const promptRequest = supportAgent.prompt(body.messages)

  return createEventStream(promptRequest.stream(), {
    format: 'jsonl',
  })
}

The package uses standard Request, Response, and Web Streams types, so it is not coupled to a specific router. The hosting framework must return the Response without consuming or buffering its body.

JSONL is the default and matches the default @anvia/react transport. Use SSE only when the client requires text/event-stream.

Server does not authenticate the route, validate session ownership, impose rate limits, or construct the agent. Do that before creating the prompt request.

Continue with transports, streaming behavior, and deployment.
