Overview

This library is used to work with Plex OAuth to get an auth token used for making requests to a Plex server's API

As a note, these auth tokens should not be public. If you are making an app using a Plex auth token, it is recommended to not use the auth token on a frontend. If you need to authenticate a frontend system, then you should use the Plex auth token on the backend to make requests to the Plex server and use a different type of authentication for the frontend that will work with the Plex auth token on the backend.

Installation

You can install this package through npm

npm install plex-oauth

Usage

There are only 2 main functions to use in the PlexOauth class (requestHostedLoginURL & checkForAuthToken). These will both return promises. If either of these functions throw an error, it needs to be explicitly caught with a try/catch or using .catch(err) on the promise itself.

Please look at the following example of how to get the Plex hosted login UI URL and how to query for the auth token:

import { PlexOauth, IPlexClientDetails } from "plex-oauth"

let clientInformation: IPlexClientDetails = {
    clientIdentifier: "<PROVIDE_UNIQUE_VALUE>", // This is a unique identifier used to identify your app with Plex.
    product: "<NAME_OF_YOUR_APP>",              // Name of your application
    device: "<NAME_OF_YOUR_DEVICE>",            // The type of device your application is running on
    version: "1",                               // Version of your application
    forwardUrl: "https://localhost:3000",       // Optional - Url to forward back to after signing in.
    platform: "Web",                            // Optional - Platform your application runs on - Defaults to 'Web'
    urlencode: true                             // Optional - If set to true, the output URL is url encoded, otherwise if not specified or 'false', the output URL will return as-is
}

let plexOauth = new PlexOauth(clientInformation);

// Get hosted UI URL and Pin Id
plexOauth.requestHostedLoginURL().then(data => {
    let [hostedUILink, pinId] = data;

    console.log(hostedUILink); // UI URL used to log into Plex

    /*
    * You can now navigate the user's browser to the 'hostedUILink'. This will include the forward URL
    * for your application, so when they have finished signing into Plex, they will be redirected back
    * to the specified URL. From there, you just need to perform a query to check for the auth token.
    * (See Below)
    */

   // Check for the auth token, once returning to the application
   plexOauth.checkForAuthToken(pinId).then(authToken => {
       console.log(authToken); // Returns the auth token if set, otherwise returns null

       // An auth token will only be null if the user never signs into the hosted UI, or you stop checking for a new one before they can log in
   }).catch(err => {
       throw err;
   });

}).catch(err => {
    throw err;
});
