Mux TypeScript API Library

This library provides convenient access to the Mux REST API from server-side TypeScript or JavaScript.

The REST API documentation can be found on docs.mux.com. The full API of this library can be found in api.md.

Note: As of v14 of mux-node-sdk, we have changed some internal workings of the SDKs. You can read more about this here.

MCP Server

Use the Mux MCP Server to enable AI assistants to interact with this API, allowing them to explore endpoints, make test requests, and use documentation to help integrate this SDK into your application.

Note: You may need to set environment variables in your MCP client.

Installation

npm install @mux/ts

Usage

The full API of this library can be found in api.md.

import Mux from '@mux/ts';

const client = new Mux({
  tokenId: process.env['MUX_TOKEN_ID'], // This is the default and can be omitted
  tokenSecret: process.env['MUX_TOKEN_SECRET'], // This is the default and can be omitted
});

const asset = await client.video.assets.create({
  inputs: [{ url: 'https://storage.googleapis.com/muxdemofiles/mux-video-intro.mp4' }],
  playback_policies: ['public'],
});

console.log(asset.id);

Request & Response types

This library includes TypeScript definitions for all request params and response fields. You may import and use them like so:

import Mux from '@mux/ts';

const client = new Mux({
  tokenId: process.env['MUX_TOKEN_ID'], // This is the default and can be omitted
  tokenSecret: process.env['MUX_TOKEN_SECRET'], // This is the default and can be omitted
});

const params: Mux.Video.AssetCreateParams = {
  inputs: [{ url: 'https://storage.googleapis.com/muxdemofiles/mux-video-intro.mp4' }],
  playback_policies: ['public'],
};
const asset: Mux.Video.Asset = await client.video.assets.create(params);

Documentation for each method, request param, and response field are available in docstrings and will appear on hover in most modern editors.

JWT Helpers (API Reference)

You can use any JWT-compatible library, but we've included some light helpers in the SDK to make it easier to get up and running.

// Assuming you have your signing key specified in your environment variables:
// Signing token ID: process.env.MUX_SIGNING_KEY
// Signing token secret: process.env.MUX_PRIVATE_KEY

// Most simple request, defaults to type video and is valid for 7 days.
const token = mux.jwt.signPlaybackId('some-playback-id');
// https://stream.mux.com/some-playback-id.m3u8?token=${token}

// If you wanted to sign a thumbnail
const thumbParams = { time: 14, width: 100 };
const thumbToken = mux.jwt.signPlaybackId('some-playback-id', {
  type: 'thumbnail',
  params: thumbParams,
});
// https://image.mux.com/some-playback-id/thumbnail.jpg?token=${token}

// If you wanted to sign a gif
const gifToken = mux.jwt.signPlaybackId('some-playback-id', { type: 'gif' });
// https://image.mux.com/some-playback-id/animated.gif?token=${token}

// Here's an example for a storyboard
const storyboardToken = mux.jwt.signPlaybackId('some-playback-id', {
  type: 'storyboard',
});

// https://image.mux.com/some-playback-id/storyboard.jpg?token=${token}

// You can also use `signViewerCounts` to get a token
// used for requests to the Mux Engagement Counts API
// https://docs.mux.com/guides/see-how-many-people-are-watching
const statsToken = mux.jwt.signViewerCounts('some-live-stream-id', {
  type: 'live_stream',
});

// https://stats.mux.com/counts?token={statsToken}

Signing multiple JWTs at once

In cases you need multiple tokens, like when using Mux Player, things can get unwieldy pretty quickly. For example,
