Cloudflare Workers 和 Hono 框架的组合正在重新定义全栈开发。本文从项目搭建到部署，展示如何用边缘计算构建低延迟的全栈应用。
The combination of Cloudflare Workers and Hono framework is redefining full-stack development. This article shows how to build low-latency full-stack applications with edge computing, from setup to deployment.
为什么选择边缘计算传统服务器部署在特定区域的数据中心，用户请求需要跨区域传输。边缘计算将代码部署到全球 300+ 个节点，用户请求就近处理，延迟可降低至 10ms 以内。Hono 框架简介Hono 是一个轻量级、高性能的 Web 框架，专为边缘运行时设计：包体积仅 14KB（gzip 后）支持 Cloudflare Workers、Deno、Bun、Node.js 等多种运行时API 与 Express 类似，学习成本低内置中间件：CORS、JWT、Logger、Compress 等实战项目我们构建一个带用户认证的短链接服务：import { Hono } from 'hono' import { jwt } from 'hono/jwt' const app = new Hono() app.post('/api/shorten', jwt({ secret: 'xxx' }), async (c) => { const { url } = await c.req.json() const key = generateKey() await c.env.LINKS.put(key, url) return c.json({ short: `https://s.idev.my/${key}` }) }) app.get('/:key', async (c) => { const url = await c.env.LINKS.get(c.req.param('key')) if (!url) return c.notFound() return c.redirect(url, 301) })数据存储Cloudflare 提供多种存储方案：KV（键值）、D1（SQLite）、R2（对象存储）。短链接服务使用 KV 存储即可满足需求。部署npx wrangler deploy一条命令即可部署到全球 300+ 节点。首次部署后，后续更新通常在 15 秒内全球生效。
Why Edge ComputingTraditional servers are deployed in specific regional data centers, requiring cross-region transmission for user requests. Edge computing deploys code to 300+ global nodes, processing requests near the user and reducing latency to under 10ms.Hono Framework OverviewHono is a lightweight, high-performance web framework designed for edge runtimes:Bundle size of only 14KB (gzipped)Supports Cloudflare Workers, Deno, Bun, Node.js and other runtimesExpress-like API with low learning curveBuilt-in middleware: CORS, JWT, Logger, Compress, etc.Hands-On ProjectWe'll build a URL shortener service with authentication:import { Hono } from 'hono' import { jwt } from 'hono/jwt' const app = new Hono() app.post('/api/shorten', jwt({ secret: 'xxx' }), async (c) => { const { url } = await c.req.json() const key = generateKey() await c.env.LINKS.put(key, url) return c.json({ short: `https://s.idev.my/${key}` }) }) app.get('/:key', async (c) => { const url = await c.env.LINKS.get(c.req.param('key')) if (!url) return c.notFound() return c.redirect(url, 301) })Data StorageCloudflare offers multiple storage options: KV (key-value), D1 (SQLite), R2 (object storage). KV storage is sufficient for a URL shortener service.Deploymentnpx wrangler deployA single command deploys to 300+ global nodes. After the first deployment, subsequent updates typically take effect globally within 15 seconds.
