Cloudflare: Flue#

Deploys a Flue agent app to Cloudflare Workers with Cloudflare.Website.Vite. vite.config.ts is Flue's documented Cloudflare setup, unchanged:

plugins: [flue(), cloudflare({ config: flueWorkerConfig() })];

Alchemy builds and serves the Worker in place of @cloudflare/vite-plugin, so the Worker settings Flue contributes through flueWorkerConfig() are declared in alchemy.run.ts instead of wrangler.jsonc:

• main: "virtual:flue/worker", Flue's generated Worker entry.
• The nodejs_compat flag and a compatibility date of 2026-04-01 or later.
• One Durable Object per 'use agent' agent. The Assistant agent in src/agents/assistant.ts is the class FlueAssistantAgent, bound as FLUE_ASSISTANT_AGENT.
• The Workers AI binding (AI), which the agent's cloudflare/... model calls go through, so no provider API key is needed.

src/app.ts is the route map: a Hono app with /api/ping and the agent mounted at /agents/assistant.

Deploy#

bun run deploy

Talk to the agent with @flue/sdk:

import { createFlueClient } from "@flue/sdk";

const client = createFlueClient({ url: `${url}/agents/assistant/demo-1` });
const admission = await client.send({ message: { kind: "user", body: "Hello!" } });
const { text } = await client.read(admission);
