Scalar for Hono

Version Downloads License Discord

This middleware provides an easy way to render a beautiful API reference based on an OpenAPI/Swagger document with Hono.

hono-js

Installation

npm install @scalar/hono-api-reference

Usage

Set up Zod OpenAPI Hono and pass the configured URL to the Scalar middleware:

import { Hono } from 'hono'
import { Scalar } from '@scalar/hono-api-reference'

const app = new Hono()

// Use the middleware to serve the Scalar API Reference at /scalar
app.get('/scalar', Scalar({ url: '/doc' }))

export default app

The Hono middleware takes our universal configuration object, read more about configuration in the core package README.

Themes

The middleware comes with a custom theme for Hono. You can use one of the other predefined themes (alternate, default, moon, purple, solarized) or overwrite it with none. All themes come with a light and dark color scheme.

import { Scalar } from '@scalar/hono-api-reference'

// Switch the theme (or pass other options)
app.get('/scalar', Scalar({
  url: '/doc',
  theme: 'purple',
}))

Custom page title

There’s one additional option to set the page title:

import { Scalar } from '@scalar/hono-api-reference'

// Set a page title
app.get('/scalar', Scalar({
  url: '/doc',
  pageTitle: 'Awesome API',
}))

Custom CDN

You can use a custom CDN ，default is https://cdn.jsdelivr.net/npm/@scalar/api-reference.

You can also pin the CDN to a specific version by specifying it in the CDN string like https://cdn.jsdelivr.net/npm/@scalar/[email protected]

You can find all available CDN versions here

import { Scalar } from '@scalar/hono-api-reference'

app.get('/scalar', Scalar({ url: '/doc', pageTitle: 'Awesome API' }))

app.get('/scalar', Scalar({
  url: '/doc',
  cdn: 'https://cdn.jsdelivr.net/npm/@scalar/api-reference@latest',
}))
