# Miru Extension API V1 (Legacy)

Miru API V1 uses a class-based inheritance approach. This version is maintained for backward compatibility but V2 is recommended for new extensions.

## Core Interface

To implement a V1 extension, you must define a class that extends the base `Extension` class.

```javascript
class MyExtension extends Extension {
    async load() { 
        // Initialization
    }
    
    async latest(page) {
        // Return latest items
    }
    
    async search(kw, page, filter) {
        // Search items
    }
    
    async createFilter(filter) {
        // Define filters
    }
    
    async detail(url) {
        // Get details and episodes
    }
    
    async watch(url) {
        // Get playable content
    }
}
```

## Differences from V2
- **Class-Based**: Methods must be defined on a class.
- **Context**: Access metadata via `this.webSite`, `this.name`, etc.
- **Settings**: Register via `this.registerSetting()` and retrieve via `await this.getSetting()`.

## Networking & Utilities
Same as V2, you can use `fetch()` or the legacy `Miru.request()`. Built-in modules like `linkedom` and `crypto-js` are available via `require()`.
