Getting started

npm install aria2

---

var Aria2 = require("aria2");

or

<script src="node_modules/aria2/bundle.js"></script>

var Aria2 = window.Aria2;

---

Start aria2c in daemon mode with

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

↑

Usage

var aria2 = new Aria2([options]);

default options match aria2c defaults and are

{
  host: 'localhost',
  port: 6800,
  secure: false,
  secret: '',
  path: '/jsonrpc'
}

secret is optional and refers to --rpc-secret.

If the WebSocket is open (via the open method) aria2.js will use the WebSocket transport, otherwise the HTTP transport.

For HTTP, aria2.js makes use of the new fetch standard, you might need a polyfill if you want to support older browsers.

↑

open

aria2.open() opens the WebSocket connection.

aria2.onopen = function() {
  console.log("aria2 open");
};

aria2.open([cb]);
// or
aria2.open().then(fn);

↑

close

aria2.close() closes the WebSocket connection.

aria2.onclose = function() {
  console.log("aria2 closed!");
};

aria2.close([cb]); // callback style
// or
aria2.close().then(fn); // promise style

↑

onsend and onmessage

aria2.onsend() is called for every message sent. aria2.onmessage() is called for every message received.

aria2.onsend = function(m) {
  console.log("aria2 OUT", m);
};
aria2.onmessage = function(m) {
  console.log("aria2 IN", m);
};

↑

aria2 methods

For a complete listing see aria2 methods.

If you passed the secret option to aria2.js, it will be automatically added to every request so there is no need to include it.

For every aria2 methods you can use

callback style

aria2.getVersion([params,] function(err, res) {
  console.log(err || res);
});

or

aria2.send('getVersion', [params,] function(err, res) {
  console.log(err || res);
});

promise style

aria2.getVersion([params]).then(fn);

or

aria2.send("getVersion", [params]).then(fn);

↑

aria2 events

For a complete listing see aria2 notifications.

For every notifications you can bind a function.

aria2.onDownloadStart = function(gid) {
  console.log(gid);
};
