实战指南：用 Hono + Cloudflare Workers 构建全球边缘 API
Practical Guide: Building Global Edge APIs with Hono and Cloudflare Workers

Hono 是一个超轻量的 Web 框架，运行在 Cloudflare Workers 上可以实现全球边缘部署。本文从零构建一个带认证、限流和缓存的边缘 API 服务。
Hono is an ultra-lightweight web framework that runs on Cloudflare Workers for global edge deployment. This guide builds an edge API with auth, rate limiting, and caching from scratch.
为什么选择边缘计算传统 API 部署在单一区域的服务器上，全球用户的延迟差异很大。边缘计算将代码部署到全球 300+ 节点，用户请求就近处理，延迟降至 10-50ms。Hono 框架简介Hono 是一个 TypeScript Web 框架，核心包仅 14KB，专为边缘运行时设计：import { Hono } from "hono" const app = new Hono() app.get("/api/hello", (c) => { return c.json({ message: "Hello from the edge!" }) }) export default app添加 JWT 认证import { jwt } from "hono/jwt" app.use("/api/protected/*", jwt({ secret: "your-secret" }))边缘限流利用 Cloudflare KV 实现分布式限流，每个边缘节点共享计数器。性能对比冷启动：Hono + Workers 0ms（无冷启动），Lambda 200-500ms全球延迟：Workers P50 = 15ms，单区域服务器 P50 = 80-300ms成本：Workers 免费额度 10 万请求/天对于读多写少的 API 场景（如内容分发、配置下发、用户认证），边缘部署是性价比最高的方案。
Why Edge ComputingTraditional APIs deployed in a single region have significant latency variations globally. Edge computing deploys code to 300+ nodes worldwide, reducing latency to 10-50ms.Hono FrameworkHono is a TypeScript web framework with a 14KB core, designed for edge runtimes. Combined with Cloudflare Workers, it offers zero cold starts and global P50 latency of 15ms.PerformanceZero cold start (vs Lambda 200-500ms)Global P50: 15ms (vs single-region 80-300ms)Free tier: 100K requests/day
