OpenMeet

OpenMeet is a browser-based P2P video meeting app. It runs as one Cloudflare Worker and uses HeteroNet Flow for room lifecycle, WebSocket signaling, STUN, and automatic TURN fallback.

Production: https://open-meet.mizuame.app

Architecture

• The Cloudflare Worker serves the Vite SPA and the same-origin /api/* routes.
• The Worker stores the HeteroCloud developer credential as a Cloudflare secret.
• The Worker creates or reads Flow rooms, validates optional room passwords, and mints five-minute participant contexts.
• Browsers connect directly to Flow signaling and pass Flow's ICE server list to RTCPeerConnection unchanged.
• Media is browser-to-browser whenever ICE can establish a direct route. Flow TURN is used automatically when it cannot.
• Chat, participant state, moderation messages, and file transfer use authenticated WebRTC data channels.

There is no Express, Socket.IO, self-hosted TURN, Docker, VM, or long-running application server.

Local development

Requirements: Node.js, npm, a HeteroCloud Flow service, and its hcf_... developer credential.

cd web
npm install
cp .dev.vars.example .dev.vars
# Set HETEROCLOUD_FLOW_CREDENTIAL in .dev.vars
npm run dev

npm run dev:web starts only Vite and therefore does not provide the room API. Use npm run dev for an end-to-end local Worker.

Checks

cd web
npm run check

Deploy

Authenticate Wrangler, register the secret once, and deploy:

cd web
wrangler login
wrangler secret put HETEROCLOUD_FLOW_CREDENTIAL
npm run deploy

The non-secret Flow endpoint configuration and static asset routing are declared in web/wrangler.jsonc.
