Overview

Server handlers are framework-agnostic handlers that run on your backend to manage protocol operations that require server-side logic.

Handlers are compatible with any server framework that supports the:

Fetch API, and is exposed via the Handler#fetch function
Node.js RequestListener API, and is exposed via the Handler#listener function

import { Handler } from 'tempo.ts/server'
import { account, client } from './config'
 
const handler = Handler.feePayer({
  account,
  client,
  feeToken: '0x20c0…0001'
  path: '/fee-payer',
})
 
createServer(handler.listener) // Node.js
 
Bun.serve(handler) // Bun
 
Deno.serve(handler) // Deno
 
app.all('*', c => handler.fetch(c.request)) // Elysia
 
app.use(handler.listener) // Express
 
app.use(c => handler.fetch(c.req.raw)) // Hono
 
export const GET = handler.fetch // Next.js
export const POST = handler.fetch // Next.js
