How to build a video hosting platform in Bubble

You build a video‑hosting platform in Bubble by combining a Video data type, a way to upload large video files (usually Mux), workflows that store the upload + playback URL, and pages that list and play videos using Bubble’s Video element. Bubble handles the front‑end; Mux handles the heavy video processing.

Core Structure

Create a Video data type with fields:

• title (text)
• file\_id (text from Mux upload result)
• playback\_url (text from Mux asset)
• uploader (user)

Bubble’s own storage works for small videos, but real hosting needs Mux because it handles encoding, streaming, and thumbnails.

Uploading Videos (Real Bubble Pattern)

Use Bubble’s API Connector to send the uploaded file to Mux. The upload input in Bubble gives you a file’s URL, which you pass to Mux’s upload endpoint. After Mux finishes processing, it gives you an asset ID and a playback ID.

// Mux direct upload request (API Connector)
{
  "input": "https://your-bubble-file-url.com/file.mp4",
  "playback_policy": ["public"]
}

You store those values in the new Video thing via a backend workflow.

Displaying Videos

To play a video, place Bubble’s Video element and set its source to the Mux playback URL:

https://stream.mux.com/[PLAYBACK_ID].m3u8

This loads instantly and streams efficiently on all devices.

Pages You Need

• Upload page: file uploader → API Connector call → create Video.
• Video list page: repeating group showing all Videos.
• Video watch page: Video element using playback\_url.

Privacy Rules

• Allow View on Video for everyone or only logged‑in users.
• Allow Create only for logged‑in users who upload.

Because streaming happens from Mux, Bubble performance stays fast while the database only stores metadata.
