Getting started

bash

pnpm add pipeway pipeway-steps zod

Your first handler

ts

import { pipe, ok } from 'pipeway'
import { body } from 'pipeway-steps'
import { z } from 'zod'

const createTodo = pipe()
  .use((ctx) => ok({ requestId: crypto.randomUUID() }))
  .use(body(z.object({ title: z.string().min(1) })))
  .handle(({ body, requestId }) => ({ id: requestId, title: body.title }))

createTodo is a (req: Request, params) => Promise<Response>. Mount it anywhere.

On Bun (no adapter)

ts

Bun.serve({
  fetch: (req) => createTodo(req, {}),
})

On Express (Node adapter)

ts

import express from 'express'
import { toNode } from 'pipeway-adapter-node'

express().post('/todos', toNode(createTodo))
