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
