This tutorial teaches you how to manage recordings of your video calls with Twilio Compositions API using Node.js, Express, and TypeScript. You start by setting up a new project, installing dependencies, and creating an Express server that uses the Compositions API to create, view, download, and delete video compositions. The application also uses Socket.IO for real-time status updates and ngrok to forward requests from your local machine to a temporary public URL. Once you've set up the server, you can record a video call using Twilio Video App React, compose the recording into a playable video file, and view or download it in your browser. The application also includes features for deleting compositions and viewing status updates, making it a useful tool for managing video recordings.
