Let Users Share Their Online Status in Your App with Express, Svelte, and Twilio Sync

Twilio Sync allows users to share their online status in an app using Express, Svelte, and Twilio Sync. To achieve this, you need to set up a backend server with Express, generate an Access Token, and create a frontend client that uses the Twilio Sync JavaScript SDK. The frontend will render a list of online users and update in real-time as users join or leave. The app also includes features like user sign-in and removal, allowing multiple users to collaborate simultaneously.
