plex-api

Small module which helps you query the Plex Media Server HTTP API.

Usage

$ npm install plex-api --save

PlexAPI(options | hostname)

Instantiate a PlexAPI client.

The parameter can be a string representing the server's hostname, or an object with the following properties:

Options:

hostname: hostname where Plex Server runs
port: port number Plex Server is listening on (optional, default: 32400)
https: (optional, default: false)
username: plex.tv username (optional / required for PlexHome)
password: plex.tv password (optional / required for PlexHome)
managedUser: details required to perform operations as a managed PlexHome user
- name: managed user name
- pin: optional pin code for the managed user
token: plex.tv authentication token (optional)
timeout: timeout value in milliseconds to use when making requests (optional)
options: override additional PlexHome options (optional, but recommended for PlexHome)
- identifier: A unique client identifier. Default is a generated uuid v4. Note: you should really provide this rather than let it get generated. Every time your app runs, a new "device" will get registered on your Plex account, which can lead to poor performance once hundreds or thousands of them get created. Trust me!
- product: The name of your application. Official Plex examples: Plex Web, Plex Home Theater, Plex for Xbox One. Default Node.js App
- version: The version of your app. Default 1.0
- deviceName: The "name" of the device your app is running on. For apps like Plex Home Theater and mobile apps, it's the computer or phone's name chosen by the user. Default Node.js App
- platform: The platform your app is running on. The use of this is inconsistent in the official Plex apps. It is not displayed on the web interface. Official Plex examples: Chrome, Plex Home Theater, Windows. Default is Node.js.
- platformVersion: The platform version. Default is the version of Node running.
- device: The name of the type of computer your app is running on, usually the OS name. Official Plex examples: Windows, iPhone, Xbox One. Default is whatever os.platform() returns.

Here's an example of what an app shows up as on the Plex web interface

The rows in that example from top to bottom are deviceName, version, product, and device.

.query(options)

Retrieve content from URI

The parameter can be a string representing the URI, or an object with the following properties:

uri: the URI to query
(optional) extraHeaders: an object with extra headers to send in the HTTP request. Useful for things like X-Plex-Target-Client-Identifier

Aside from requesting the API and returning its response, an .uri property are created to easier follow the URIs available in the HTTP API. At the moment URIs are attached for Directory and Server items.

var PlexAPI = require("plex-api");
var client = new PlexAPI("192.168.0.1");

client.query("/").then(function (result) {
	console.log("%s running Plex Media Server v%s",
		result.friendlyName,
		result.version);

	// array of children, such as Directory or Server items
	// will have the .uri-property attached
	console.log(result._children);
}, function (err) {
	console.error("Could not connect to server", err);
});

.postQuery(options)

Send a POST request and retrieve the response

This is identical to query(), except that the request will be a POST rather than a GET. It has the same required and optional parameters as query().

Note that the parameters can only be passed as a query string as part of the uri, which is all Plex requires. (Content-Length will always be zero)

var PlexAPI = require("plex-api");
var client = new PlexAPI("192.168.0.1");

client.postQuery("/playQueue?type=video&uri=someuri&shuffle=0").then(function (result) {
	console.log("Added video to playQueue %s",
		result.playQueueID);

	// array of children, such as Directory or Server items
	// will have the .uri-property attached
	console.log(result._children);
}, function (err) {
	console.error("Could not connect to server", err);
});

.putQuery(options)

Send a PUT request and retrieve the response

This is identical to query(), except that the request will be a PUT rather than a GET. It has the same required and optional parameters as query(). It's is used to update parts of your Plex library.

Note that the parameters can only be passed as a query string as part of the uri, which is all Plex requires. (Content-Length will always be zero)

var PlexAPI = require("plex-api");
var client = new PlexAPI("192.168.0.1");

client.putQuery("/library/sections/3/all?type=1&id=123&summary.value=updatedSummaryText")
	.then(function (result) {
		console.log("Description of video by id 123 has been set to 'updatedSummaryText'");
	}, function (err) {
		console.error("Could not connect to server", err);
	});

.perform(options)

Perform an API action

When performing an "action" on the HTTP API, the response body will be empty. As the response content itself is worthless, perform() acts on the HTTP status codes the server responds with. It has the same required and optional parameters as query().

var PlexAPI = require("plex-api");
var client = new PlexAPI("192.168.0.1");

// update library section of key "1"
client.perform("/library/sections/1/refresh").then(function () {
	// successfully started to refresh library section #1
}, function (err) {
	console.error("Could not connect to server", err);
});

.find(options, [{criterias}])

Find matching child items on URI

Uses query() behind the scenes, giving all directories and servers the beloved .uri property. It has the same required and optional parameters as query, in addition to a second optional criterias parameter.

var PlexAPI = require("plex-api");
var client = new PlexAPI("192.168.0.1");

// filter directories on Directory attributes
client.find("/library/sections", {type: "movie"}).then(function (directories) {
	// directories would be an array of sections whose type are "movie"
}, function (err) {
	console.error("Could not connect to server", err);
});

// criterias are interpreted as regular expressions
client.find("/library/sections", {type: "movie|shows"}).then(function (directories) {
	// directories type would be "movie" OR "shows"
}, function (err) {
	console.error("Could not connect to server", err);
});

// shorthand to retrieve all Directories
client.find("/").then(function (directories) {
	// directories would be an array of Directory items
}, function (err) {
	throw new Error("Could not connect to server");
});

Authenticators

An authenticator is used by plex-api to authenticate its request against Plex Servers with a PlexHome setup. The most common authentication mechanism is by username and password.

You can provide your own custom authentication mechanism, read more about custom authenticators below.

Credentials: username and password

Comes bundled with plex-api. Just provide options.username and options.password when creating a PlexAPI instance and you are good to go.

See the plex-api-credentials module for more information about its inner workings.

PIN: authenticate by PIN code

An authentication module that provides an interface for authenticating with Plex using a PIN, like the official clients do.

https://www.npmjs.com/package/plex-api-pinauth

Custom authenticator

In its simplest form an authenticator is an object with one required function authenticate() which should return the autentication token needed by plex-api to satisfy Plex Server.

An optional method initialize() could be implemented if you need reference to the created PlexAPI instance when it's created.

{
  // OPTIONAL
  initialize: function(plexApi) {
    // plexApi === the PlexAPI instance just created
  },
  // REQUIRED
  authenticate: function(plexApi, callback) {
    // plexApi === the PlexAPI instance requesting the authentication token

    // invoke callback if something fails
    if (somethingFailed) {
      return callback(new Error('I haz no cluez about token!'));
    }

    // or when you have a token
    callback(null, 'I-found-this-token');
  }
}
