Dev Helper

Dev Helper provides useful methods you can use in development.

import { Hono } from 'hono'
import { getRouterName, showRoutes } from 'hono/dev'

getRouterName()

You can get the name of the currently used router with getRouterName().

const app = new Hono()
 
// ...
 
console.log(getRouterName(app))

showRoutes()

showRoutes() function displays the registered routes in your console.

Consider an application like the following:

const app = new Hono().basePath('/v1')
 
app.get('/posts', (c) => {
  // ...
})
 
app.get('/posts/:id', (c) => {
  // ...
})
 
app.post('/posts', (c) => {
  // ...
})
 
showRoutes(app, {
  verbose: true,
})

When this application starts running, the routes will be shown in your console as follows:

GET   /v1/posts
GET   /v1/posts/:id
POST  /v1/posts

Options

verbose: boolean

When set to true, it displays verbose information.

colorize: boolean

When set to false, the output will not be colored.
