Hono

Hono

Hono (Japanese for "Flame") is a small, simple, and ultrafast web framework built on Web Standards. It runs anywhere: Cloudflare Workers, Fastly, Deno, Bun, Node.js, and Vercel.
Hono（日语意为“火焰”）是一款基于Web标准构建的轻量、简洁且超快速的Web框架。它可在任意环境运行：Cloudflare Workers、Fastly、Deno、Bun、Node.js以及Vercel。

When to Use

适用场景

  • Edge Computing: Explicitly designed for Cloudflare Workers / Edge runtimes.
  • Performance: Uses 
    RegExpRouter
    , making it significantly faster than Express.
  • Single File API: Perfect for small microservices or proxy servers.
  • 边缘计算：专为Cloudflare Workers / 边缘运行时设计。
  • 性能优势：采用
    RegExpRouter
    ，速度显著快于Express。
  • 单文件API：非常适合小型微服务或代理服务器。

Quick Start

快速开始

typescript
import { Hono } from "hono";
const app = new Hono();

app.get("/", (c) => c.text("Hello Hono!"));

app.get("/user/:name", (c) => {
  const name = c.req.param("name");
  return c.json({ message: `Hello ${name}!` });
});

export default app;
typescript
import { Hono } from "hono";
const app = new Hono();

app.get("/", (c) => c.text("Hello Hono!"));

app.get("/user/:name", (c) => {
  const name = c.req.param("name");
  return c.json({ message: `Hello ${name}!` });
});

export default app;

Core Concepts

核心概念

Web Standards

Web标准

Hono uses standard 
Request
and 
Response
objects. No proprietary API wrapper.
Hono使用标准的
Request
和
Response
对象，无专有API封装。

Middleware

中间件

Similar to Express but 
await next()
. Batteries included: CORS, JWT, Basic Auth, Cache.
与Express类似，但需使用
await next()
。内置多种实用功能：CORS、JWT、基础认证（Basic Auth）、缓存（Cache）。

RPC (Hono RPC)

RPC（Hono RPC）

Share types between client and server for end-to-end type safety without GraphQL.
无需GraphQL，即可在客户端与服务器之间共享类型，实现端到端的类型安全。

Best Practices (2025)

2025年最佳实践

Do:
  • Use Hono RPC: If you control both client and server, the typed client is amazing.
  • Run on Bun: Hono + Bun is currently one of the fastest combinations for JS backends.
Don't:
  • Don't use heavy Node.js dependencies: If targeting Cloudflare Workers, avoid packages that rely on 
    fs
    or native Node modules.
建议：
  • 使用Hono RPC：若你同时控制客户端和服务器，类型化客户端的体验极佳。
  • 在Bun上运行：目前Hono + Bun是JS后端最快的组合之一。
避免：
  • 不要使用重型Node.js依赖：若目标环境为Cloudflare Workers，避免依赖
    fs
    或Node.js原生模块的包。
