Node.js TypeScript library for [aria2](https://aria2.github.io/).

## Introduction

libaria2 uses [Aria2 JSON-RPC Interface](https://aria2.github.io/manual/en/html/aria2c.html#rpc-interface) to control it.

## Features

- Multiple Transports
  - [HTTP](https://aria2.github.io/manual/en/html/aria2c.html#rpc-interface)
  - [WebSocket](https://aria2.github.io/manual/en/html/aria2c.html#json-rpc-over-websocket)
- Promise-based API
- Full-Typing, JSDoc

## Getting Started

Install this package

```bash
npm install libaria2
```

Start aria2 with rpc, example

```bash
aria2c --enable-rpc --rpc-listen-all=true --rpc-allow-origin-all
```

## Usage

### Create client

```ts
import { WebSocket as Aria2WebSocket } from "libaria2-ts";

const aria2 = new Aria2WebSocket({
  host: 'localhost',
  port: 6800
});
```

```ts
import { Http as Aria2Http } from "libaria2-ts";

const aria2 = new Aria2Http({
  host: 'localhost',
  port: 6800
});
```

Example options

```ts
{
  host: 'localhost',
  port: 6800,
  path: '/jsonrpc',
  auth: {
    secret: 'hello'
  }
}
```

### Methods

```ts
const version = await aria2.getVersion();
/*
 * Output:
 * { version: '...', enabledFeatues: [...] }
 */

const resl = await aria2.system.multicall(
  { methodName: 'aria2.getVersion', params: [] },
  { methodName: 'aria2.addUri', params: ['http://example.com/qwer.zip'] }
);
/*
 * Output:
 * Array<Promise<...>>
 */

// or:
aria2.on('aria2.onDownloadStart', (event: IAria2NotificationEvent) => {
  console.log(`Download ${event.gid} Started`);
});

// or:
aria2.onceDownloadStart().then((event: IAria2NotificationEvent) => {
  console.log(`Download ${event.gid} Started`);
});

await aria2.closeConnection();
```
