## Introduction

NOTE: Version 3.x of this project is in pure ESM and can not be used in CommonJS projects.
If you want to use this project in a CommonJS project, please use v2.x.
Version 2 and 3 are at feature parity, it's jst the imports and exports that differ.
This is to support those who have not made the switch to ESM yet.

hapi-docs is perhaps the best and most modern <em>API Documentation Generator</em> out there. From your code blocks to description texts, you simply type everything in Markdown. Then all you need to do is to enjoy a blazing fast single-page responsive documentation, which smartly supports linkability, Syntax highlighting, RTL languages, and perfectionist eyes. hapi-docs is an open-source library brought to you by [SurveyLegend®](https://www.surveylegend.com/).

## Features

-   **Intuitive design** — Inspired by [Stripe’s](https://stripe.com/docs/api) API docs. The description of your API resides on the left part of the documentation, while all of the code examples reside on the right. Of course the layout is fully responsive and flawlessly adapts to tablets and phones.

-   **Single page** — The whole documentation resides on a single page, without sacrificing linkability. As you scroll through the documentation, your browser’s hash will update to the nearest section, which means linking to a particular point in the documentation remains natural and easy.

-   **Scroll spy** — Thanks to our custom and optimized scroll spy script, the far left navigation will smartly display your current position in the documentation, while scrolling through the documentation. It's swift and remains excellent even for larger documents.

-   **Dark theme** — Seamless switching between light and dark theme using a toggle. Supports `prefers-color-scheme` media query for automatic switching as well.

-   **Markdown support** — Use Markdown to describe your API. Markdown makes it easy to articulate your documentation.

-   **Code examples in multiple languages** — Configurable support for multiple languages. Easily choose which language to currently display in your documentation by switching between tabs.

-   **Syntax highlighting** — Supports [over 100 languages](https://prismjs.com/#languages-list) out of the box.

-   **RTL Support** — Full Right-to-Left support for languages such as Arabic, Persian (Farsi), Hebrew, etc.

-   **Anchor tags** — With one click, users can easily link to a parameter, thanks to auto generated anchor tags.

```javascript
import Hapi from '@hapi/hapi'
import Inert from '@hapi/inert'
import Joi from 'joi'
import HapiDocs from '@surveylegend/hapi-docs'
import { version } from './package'

const options = {
    info: {
        title: 'Test API Reference',
        version
    }
}

const startServer = async () => {
    const server = Hapi.server({
        host: 'localhost',
        port: 3000
    })

    await server.register([
        {
            plugin: Inert
        },
        {
            plugin: HapiDocs,
            options
        }
    ])

  options: {
    handler: [...],
    [...]
    tags: ['api']
  }
}
```
