@vafast/server-timing

Vafast Server-Timing 中间件：把 handle / total 耗时写入响应头，便于 DevTools 观察。

Installation

npm install @vafast/server-timing

Quick start

import { Server, defineRoute, defineRoutes, json, serve } from 'vafast'
import { serverTiming } from '@vafast/server-timing'

const routes = defineRoutes([
  defineRoute({
    method: 'GET',
    path: '/',
    handler: () => json({ ok: true }),
  }),
])

const server = new Server(routes)
server.use(serverTiming())
serve({ fetch: server.fetch, port: 3000 })

响应示例：Server-Timing: handle;dur=1.23,total;dur=1.25

| Option | Default | Description | |--------|---------|-------------| | enabled | NODE_ENV !== 'production' | 是否启用；生产默认关闭 | | allow | 允许写入 | boolean 或 ({ request }) => boolean \| Promise<boolean> | | trace.handle | true | 输出 handle 段 | | trace.total | true | 输出 total 段 |
