Farrow渐进式 TypeScript Web 框架

import { Http, Response } from 'farrow-http'
import { ObjectType, String, Number } from 'farrow-schema'

// 定义 Schema - 获得类型 + 验证
class CreateUserRequest extends ObjectType {
  name = String
  age = Number
}

const app = Http()

// 类型安全的路由
app.get('/users/<id:int>').use((request) => {
  // request.params.id 自动是 number 类型
  const user = getUser(request.params.id)
  return Response.json(user)
})

// 自动验证请求体
app.post('/users', { body: CreateUserRequest }).use((request) => {
  // request.body 完全类型安全
  const user = createUser(request.body)
  return Response.status(201).json(user)
})

app.listen(3000)
