muse

A library to interact with the YouTube Music (InnerTube) api.

Note: This library is still in development, and is not ready for production use.

Usage

muse works on Deno, Node.js, the browser and any javascript environment that supports ES modules and fetch.

You can read the docs for more information about the usage of each function.

Don't forget to replace VERSION with the latest version

Deno

import * as muse from "https://deno.land/x/muse@VERSION/mod.ts";

// you can also use the latest version (not recommended) with
// import * as muse from "https://deno.land/x/muse/mod.ts";

// you can also import directly from github
// import * as muse from "https://raw.githubusercontent.com/vixalien/muse/VERSION/mod.ts";

const search_results = await muse.search("drake");
const rickroll = await muse.get_song("dQw4w9WgXcQ");

Browser

You'll need to use a CDN that supports ES modules, such as esm.sh, jspm.io or skypack.dev.

Proxy

You'll also need to use a proxy server to get around CORS errors. It's a good idea to self host the proxy server (cors-anywhere and deno_deploy_cors_proxy are good options).

import * as muse from "https://esm.sh/libmuse@VERSION";

// import * as muse from "https://jspm.dev/npm:libmuse@VERSION";
// import * as muse from "https://cdn.skypack.dev/libmuse@VERSION";

// setting up our proxy
muse.set_option("fetch", (url, options) => {
  return fetch(`https://proxy.example.com/${url}`, options);
});

const search_results = await muse.search("top radio");

Node

First install using your preferred package manager (npm, yarn, pnpm etc.)

npm install libmuse

Then use it in by importing libmuse. The Node version has the exact same features as the Deno version.

import * as muse from "libmuse";
// commonjs: const muse = require("libmuse");

const artist = await muse.get_artist("UCvyjk7zKlaFyNIPZ-Pyvkng");

For the complete list of operations, see the docs.

Auth

Currently, muse supports oauth authentication by posing as the YouTube TV app.

Here's the flow:

1. Get a login code
2. Go to the given login url, and type in the login code on a device that is logged into a google account
3. Get the OAuth token & refresh tokens

import * as muse from "https://deno.land/x/muse@VERSION/mod.ts";

const auth = muse.get_option("auth");

muse.setup({
  // make sure to persist the token
  store: new DenoFileStore("store/muse-store.json"),
  debug: true,
});

// this is the authentication flow
const auth_flow = async () => {
  if (auth.has_token()) return;
  console.log("Getting login code...");

  const loginCode = await auth.get_login_code();

  console.log(
    `Go to ${loginCode.verification_url} and enter the code: ${loginCode.user_code}`,
  );

  // not necessary, but saves some requests
  alert("Press enter when you have logged in");

  console.log("Loading token...");

  await auth.load_token_with_code(
    loginCode.device_code,
    loginCode.interval,
  );

  console.log("Logged in!", auth._token);
};

// listen to the `requires-login` event, then resolve pass on a function that
// returns a promise that will resolve when the auth flow is complete
auth.addEventListener("requires-login", (event) => {
  const resolve = event.detail;

  resolve(auth_flow);
});

In the future, I plan to add support for other auth methods, such as cookies and Youtube TV login codes.

Storage

You can pass in a storage object to the client to persist the auth token.

import * as muse from "https://deno.land/x/muse@VERSION/mod.ts";

// you can use the "best" store, which is DenoFileStore if available, then LocalStorageStore, then MemoryStore
const client = muse.setup({ store: muse.get_best_store() });

// or you can use any of the built-in stores
const client = muse.setup({ store: new muse.DenoFileStore("/path/to/file.json") });
const client = muse.setup({ store: new muse.LocalStorageStore() });
const client = muse.setup({ store: new muse.MemoryStore() });

// or you can implement your own store
// by extending the Store abstract class
class MyStore extends muse.Store {
  get<T>(key: string): T | null;
  set(key: string, value: unknown): void;
  delete(key: string): void;
}

// then use it accordingly
const client = muse.setup({ store: new MyStore() });

// Do note that setup() can be called multiple times, but it's not recommended. 
// this is because setup overrides the global store, so if you call setup()
// multiple times, other options set before will be ignored. example:

muse.setup({ auth: { /* custom auth options */ } });
muse.setup({ store: /* custom store */ });

// the above will only use the custom store, and ignore the custom auth options

// if you need to configure options many times use `muse.set_option`
muse.set_option("store", /* custom store */)

Operations

I'm currently targetting to match the ytmusicapi's capabilities.
