Pretty JSON Middleware ​

Pretty JSON middleware enables "JSON pretty print" for JSON response body. Adding ?pretty to url query param, the JSON strings are prettified.

js
// GET / {"project":{"name":"Hono","repository":"https://github.com/honojs/hono"}}

will be:

js
// GET /?pretty {  "project": {  "name": "Hono",  "repository": "https://github.com/honojs/hono"  } }
