Store, stream, and embed video in your Remix.js application with the Mux API and components. Use this guide when you add video pages, user uploads, or background video to a Remix.js site.
When adding video to your Remix.js app, you'll encounter some common hurdles. First, videos are large. Storing them in your public directory can lead to excessive bandwidth consumption and poor Git repository performance. Next, it's important to compress and optimize your videos for the web. Then, as network conditions change, you might want to adapt the quality of your video to ensure a smooth playback experience for your users. Finally, you may want to integrate additional features like captions, thumbnails, and analytics.
You might consider using Mux's APIs and components to handle these challenges, and more.
The quickest way to add a video to your site is with Video.js. Install Video.js for React, the Mux video media and the Mux Data extension:
npm install @videojs/react @videojs/mux-video @videojs/mux-dataThen add a player to a route:
import '@videojs/react/video/skin.css';
import { VideoPlayer, VideoSkin } from '@videojs/react/video';
import { MuxVideo } from '@videojs/react/media/mux-video';
import { MuxData } from '@videojs/react/extensions/mux-data';
export default function Page() {
return (
<VideoPlayer>
<VideoSkin style={{ width: '100%', aspectRatio: '16 / 9' }}>
<MuxVideo
source={{ playbackId: 'jwmIE4m9De02B8TLpBHxOHX7ywGnjWxYQxork1Jn5ffE' }}
playsInline
crossOrigin="anonymous"
/>
<MuxData
metadata={{
video_title: 'Test video title',
viewer_user_id: 'user-id-007',
}}
/>
</VideoSkin>
</VideoPlayer>
);
}The Mux video media plays the video and loads its poster and timeline hover previews. The Mux Data extension monitors playback.
If your site has just a few videos, you might upload them to Mux directly through the dashboard. In the Mux Dashboard, on your video assets page, select "Create New Asset". On the next screen, you can upload a video directly to Mux.

You'll then be able to see your new asset on your video assets page. When you click on the asset, you can find the asset's playback ID in the "Playback and Thumbnails" tab. Pass this playback ID to the source prop of the MuxVideo component.

To set signed tokens, a custom domain or DRM, see Use Video.js with Mux. To change the look and feel of the player, see the Video.js documentation.
If you're managing more videos, you might take a look at our CMS integrations.
Finally, if you need more control over your video workflow, read on.
If you're looking to build your own video workflow that enables uploading, playback, and more in your application, you can use the Mux API with Video.js for playback and Mux Uploader for uploads.
One reason you might want to build your own video workflow is when you want to allow users to upload video to your app.
Let's start by adding a new page where users can upload videos. This will involve using the Mux Uploader component, which will upload videos to a Mux Direct Uploads URLAPI.
In the code sample below, we'll create an upload URL using the Mux TypeScript SDK and the Direct Uploads URL API. We'll pass that URL to the Mux Uploader component, which will handle uploading for us.
import { json } from "@remix-run/node";
import { useLoaderData } from "@remix-run/react";
import MuxUploader from "@mux/mux-uploader-react";
import mux from "~/lib/mux.server";
export const loader = async () => {
const upload = await mux.video.uploads.create({
new_asset_settings: {
playback_policy: ["public"],
video_quality: "basic",
},
cors_origin: "*",
});
return json({ url: upload.url });
};
export default function UploadPage() {
const { url } = useLoaderData();
return <MuxUploader endpoint={url} />
}In production, you'll want to apply additional security measures to your upload URL. Consider protecting the route with authentication to prevent unauthorized users from uploading videos. Also, use cors_origin and consider playback_policies to further restrict where uploads can be performed and who can view uploaded videos.
Next, we'll create an API endpoint that will listen for Mux webhooks. When we receive the notification that the video has finished uploading and is ready for playback, we'll add the video's metadata to our database.
import { json } from "@remix-run/node";
import Mux from "@mux/ts";
// this reads your MUX_TOKEN_ID and MUX_TOKEN_SECRET
// from your environment variables
// https://dashboard.mux.com/settings/access-tokens
const mux = new Mux();
// Mux webhooks POST, so let's use an action
export const action = async ({ request }) => {
if (request.method !== "POST") {
return new Response("Method not allowed", { status: 405 });
}
const body = await request.text();
// mux.webhooks.unwrap will validate that the given payload was sent by Mux and parse the payload.
// It will also provide type-safe access to the payload.
// Generate MUX_WEBHOOK_SIGNING_SECRET in the Mux dashboard
// https://dashboard.mux.com/settings/webhooks
const event = await mux.webhooks.unwrap(
body,
request.headers,
process.env.MUX_WEBHOOK_SIGNING_SECRET
);
// you can also unwrap the payload yourself:
// const event = await request.json();
switch (event.type) {
case "video.upload.asset_created":
// we might use this to know that an upload has been completed
// and we can save its assetId to our database
break;
case "video.asset.ready":
// we might use this to know that a video has been encoded
// and we can save its playbackId to our database
break;
// there are many more Mux webhook events
// check them out at https://www.mux.com/docs/webhook-reference
default:
break;
}
return json({ message: "ok" });
};Finally, let's make a playback page. We retrieve the video metadata from our database, and play it by passing its playbackId to the Video.js player. The video title and viewer ID go to Mux Data as metadata:
// npm install @videojs/react @videojs/mux-video @videojs/mux-data
import '@videojs/react/video/skin.css';
import { VideoPlayer, VideoSkin } from '@videojs/react/video';
import { MuxVideo } from '@videojs/react/media/mux-video';
import { MuxData } from '@videojs/react/extensions/mux-data';
import { json } from '@remix-run/node';
import { useLoaderData, useParams } from '@remix-run/react';
export const loader = async ({ params, request }) => {
const { title } = await getAssetFromDatabase(params);
const userId = await getUser(request);
return json({ title, userId });
};
export default function Page() {
const { title, userId } = useLoaderData();
const { playbackId } = useParams();
return (
<VideoPlayer>
<VideoSkin style={{ width: '100%', aspectRatio: '16 / 9' }}>
<MuxVideo source={{ playbackId }} playsInline crossOrigin="anonymous" />
<MuxData
metadata={{
video_title: title,
viewer_user_id: userId,
}}
/>
</VideoSkin>
</VideoPlayer>
);
}And we've got upload and playback. Nice!
What's next? You can integrate with your CMS. You can set signed tokens, a custom domain or DRM. Or get started with the example project below:
This example project still uses Mux Player. To use Video.js instead, swap the player for the one in the playback example above.
This is a bare-bones starter application with Remix.js that uses:
