Introduction

Docusaurus is a powerful static site generator designed specifically for documentation websites. It simplifies the process of creating and maintaining documentation for APIs, making it an excellent choice for developers and technical writers alike. Below are three diverse examples of using Docusaurus for API documentation, showcasing its versatility and ease of use.

Example 1: Basic API Reference Documentation

Context

Imagine you are developing a RESTful API for a weather service. You need to create comprehensive documentation that allows users to easily understand how to interact with your API.

To achieve this, you can utilize Docusaurus to structure your API reference documentation clearly and effectively.

# Weather API Documentation

## Introduction
This document provides an overview of the Weather API, which allows users to retrieve weather information.

## Endpoint
### GET /weather
Retrieve current weather data for a specified location.

### Parameters

- `location` (string, required): The name of the city for which to retrieve weather data.

### Response
```json
{
  "location": "New York",
  "temperature": "22°C",
  "condition": "Sunny"
}

Example Request

curl -X GET "https://api.weather.com/weather?location=New%20York"

### Notes

- Ensure to replace spaces in the location name with `%20` when making requests. This example can be expanded further to include additional endpoints and detailed error messages.

## Example 2: Interactive API Playground
### Context
In modern API documentation, providing an interactive playground where users can test API calls directly in the browser is highly beneficial. Docusaurus can facilitate this by integrating an API testing tool.

```markdown
# API Playground

## Test the Weather API
Use the form below to test the Weather API.

<form id="api-playground">
  <label for="location">Location:</label>
  <input type="text" id="location" name="location" value="New York">
  <button type="submit">Get Weather</button>
</form>

<div id="response"></div>

<script>
  document.getElementById('api-playground').onsubmit = function(event) {
    event.preventDefault();
    const location = document.getElementById('location').value;
    fetch(`https://api.weather.com/weather?location=${encodeURIComponent(location)}`)
      .then(response => response.json())
      .then(data => {
        document.getElementById('response').innerText = JSON.stringify(data, null, 2);
      });
  };
</script>

Notes

• This setup not only enhances user engagement but also allows users to see real-time results without leaving the documentation page.

Example 3: Versioned API Documentation

Context

As your API evolves, maintaining versioned documentation becomes crucial. Docusaurus allows you to easily manage and present different versions of your API documentation.

# Weather API Documentation

## Version 1.0
This version includes basic weather data retrieval.

### GET /weather

- **New Features**: Basic weather data

## Version 2.0
This version introduces additional features such as forecast data.

### GET /weather/forecast
Retrieve weather forecast data for a specified location.

### Parameters

- `location` (string, required): The name of the city for which to retrieve forecast data.

### Example Request
```bash
curl -X GET "https://api.weather.com/weather/forecast?location=New%20York"

```

Notes

• Use Docusaurus’ versioning feature to create a seamless transition between different versions while keeping the documentation accessible to users.

These examples illustrate how Docusaurus can be leveraged to create structured, interactive, and versioned API documentation, ensuring that users have a comprehensive understanding of your API’s capabilities.
