### [How to Use Svelte and Go to Build a Video Chat App](https://yomu.fyi/post/how-to-use-svelte-and-go-to-build-a-video-chat-app.md)

The tutorial builds a video chat application with a Svelte single-page frontend and Go REST API, using Twilio Video for room-based calls. Users enter a room name, the backend validates it, mints a Twilio Access Token with a VideoGrant, and the frontend uses that token to connect and attach local and remote video tracks. The backend loads credentials from .env.local, assigns each participant a random crypto/rand identity, enables CORS, and serves requests on port 8000; room names shorter than six characters receive a 400 response. The frontend uses Vite, the Twilio Video JavaScript SDK, and iziToast, while testing involves running both servers and joining the same room in two browser tabs. The completed app handles video communication without custom permission, real-time communication, or data-streaming code.
