Full Changelog: v2.2.0...v2.2.1

v2.2.0

This release includes ES Module support, innovative new features, and some bug fixes. You will like it.

Summary

Support ES Module

We have distributed only CommonJS, but now we will distribute ES Module. ES Module is used when the library is imported using the import keyword. ESModule may improve performance and reduces bundle size.

StaticRouter and SmartRouter

Now we have a really smart router.

Added a simple router named "StaticRouter" that does not support dynamic routes. Now, we have there router: "TrieRouter", "RegExpRouter", and "StaticRouter".

And we introduce "SmartRouter".

SmartRouter picks the optimal router from three routers the first time it is accessed. Users can use the fastest router without explicitly specifying a router.

// Before this release.
// If we wanted to use optimal router, we have to specify it.
const app = new Hono({ router: new RegExpRouter() })

// This release.
// SmartRouter selects the fastest router automatically.
const app = new Hono()

StaticRouter is used for having only static routes. Otherwise, RegExpRouter will be used, but it has routing that RegExpRouter does not support, TrieRouter will be used.

Validator Middleware

New Validator Middleware as builtin middleware. This validator is magic.

app.post(
  '/posts',
  validator((v) => ({
    post: {
      id: v.json('post.id').asNumber().isRequired(),
      title: v.json('post.title').isRequired().isLength({ max: 100 }),
      published: v.json('post.published').asBoolean(),
      body: v.json('post.body').isOptional(),
    },
  })),
  (c) => {
    const res = c.req.valid()
    const post = res.post
    return c.text(`Post: ${post.id} is ${post.title}`)
  }
)

They will have "Types"! The value validated with asNumber() keyword will have "Type".

Not only that.

• Easy to understand the result data because "declaring property name first".
• Easy to writing rules. v.isLength(400) is better than v.isLength, 400.
• Getting only "declared properties". Additional properties are always ignored. It's safe.

Validator Middleware was provided as third party Middleware: https://github.com/honojs/validator, it will be deprecated.

v2.1.0

BREAKING CHANGES

This release has the breaking changes. Please see the migration guide for more detail:

• Migration Guide

Summary

• TrieRouter is 9~10% faster.
• Enable adding types to c.set/c.get by passing the Generics to new Hono. #472
• c.req.parseBody parses only FormData. Does not parse JSON, text, or ArrayBuffer. #487

Types for c.set/c.get

Now, we can add the types to the variables used in c.set and c.get. new Hono receive the Generics for the variables and bindings which is for environment variables for Cloudflare Workers.

type Bindings = {
  KV: KVNamespace
  Storage: R2Bucket
}

type WebClient = {
  user: string
  pass: string
}

type Variables = {
  client: WebClient
}

const app = new Hono<{ Variables: Variables; Bindings: Bindings }>()

app.get('/foo', (c) => {
  const client = c.get('client') // client is WebClient
  const kv = c.env.KV // kv is KVNamespace
  //...
})

c.req.parseBody

Now, c.req.parseBody has become only for parsing FormData. We have to parse the request body explicitly.

// `multipart/form` or `application/x-www-form-urlencoded`
const data = await c.req.parseBody()

const jsonData = await c.req.json() // for JSON body
const text = await c.req.text() // for text body
const arrayBuffer = await c.req.arrayBuffer() // for ArrayBuffer

What's Changed

• perf(trie-router): fine tuning, 9~10% faster by @yusukebe in #473
• fix(context): export ContextVariableMap correctly by @yusukebe in #476
• feat(types): enable adding Types for variables used in c.set/c.get by @yusukebe in #478

v2.0.9

Summary

Performance improvement - We have revised the await/async process so that it is faster in some situations.

It has been 8-9% faster in the benchmark:

hono - trie-router(default) x 393,919 ops/sec ±4.52% (86 runs sampled)
hono - regexp-router x 478,140 ops/sec ±2.85% (83 runs sampled)
hono optimized - trie-router(default) x 427,940 ops/sec ±4.32% (81 runs sampled)
hono optimized - regexp-router x 512,488 ops/sec ±5.28% (75 runs sampled)
Fastest is hono optimized - regexp-router
✨  Done in 28.36s.

On Bun, it has been 15% faster.
