BackendServer Adapters
Generic (Workers/Deno/Bun)
Use the generic adapter for Cloudflare Workers, Deno, Bun, or any runtime with the Web Fetch API.
The generic adapter works with any runtime that supports the standard Request/Response Web API. Use it for Cloudflare Workers, Deno, Bun, or custom servers.

import { createEngine } from '@superapp/backend'
import { createHandler } from '@superapp/backend/adapters/generic'
const engine = createEngine({
connections: {
main: process.env.PG_URL!,
},
})
const handler = createHandler(engine)
Bun.serve({
port: 3001,
fetch: (req) => handler(req),
})Handler Signature
The generic handler accepts a standard Request and returns a Promise<Response>:
type GenericHandler = (request: Request) => Promise<Response>This makes it compatible with any runtime or framework that uses the Web Fetch API standard.
