Compress Middleware

This middleware compresses the response body, according to Accept-Encoding request header.

INFO

Note: On Cloudflare Workers, the response body will be compressed automatically, so there is no need to use this middleware.

Bun: This middleware uses CompressionStream which is not yet supported in bun.

Import

npm

import { Hono } from 'hono'
import { compress } from 'hono/compress'

Deno

import { Hono } from 'https://deno.land/x/hono/mod.ts'
import { compress } from 'https://deno.land/x/hono/middleware.ts'

Usage

const app = new Hono()

app.use(compress())

Options

• encoding: 'gzip' | 'deflate'
  • The compression scheme to allow for response compression. Either gzip or deflate. If not defined, both are allowed and will be used based on the Accept-Encoding header. gzip is prioritized if this option is not provided and the client provides both in the Accept-Encoding header.
