cometchat-js-v5-sdk

Ground truth: @cometchat/calls-sdk-javascript@5 + catalog web-calls-v5.json (the closed symbol list — every CometChatCalls.* below exists in it). Official docs: /calls/javascript/** = v5 · Docs MCP. Fetch exact SessionSettings fields, event names, and action-method signatures from the docs (references/docs-map.md) — never memory. APPEND to the user's app — additive wiring only (RULES.md). This is the HEADLESS path (no UI Kit); for the prebuilt drop-in call UI use cometchat-react-v7-calls instead.

Companion skills (read first)

• Standalone/headless entry — this skill owns its own package (the Calls SDK) and has no -core sibling; it is self-contained for meet-style calling.
• For 1:1 RINGING only it also drives the Chat SDK (@cometchat/chat-sdk-javascript@4) for call signaling — signatures fetched from docs via references/docs-map.md (§ "1:1 RINGING"). It does NOT depend on the React UI Kit.
• Prefer the UI Kit instead? If the app also wants chat and a prebuilt call UI, use cometchat-react-v7-core + cometchat-react-v7-calls — not this skill.

Use this skill when

"add calling from scratch / without the UI Kit", "standalone voice/video", "build my own call screen", "headless calls SDK", "meeting-room join by session id", "one-on-one ringing call". Precondition: the caller chose the from-scratch / standalone path (the "add calling" router asks this). If they want the prebuilt call UI, route to cometchat-react-v7-calls.

Prerequisites & install

npm install @cometchat/calls-sdk-javascript@5

• 1:1 ringing additionally needs the Chat SDK for signaling:

  npm install @cometchat/chat-sdk-javascript@4
  

• Credentials/env: App ID · Region · Auth Key (dev only). To fetch from the dashboard, load the CLI on demand — npx @cometchat/skills-cli@3 auth login → provision use --app-id <id> --json (writes .cometchat/config.json; @3 pins the CLI major that matches the v5 skills). Or paste manually from Dashboard → Credentials. Mint auth tokens server-side for production; never ship the Auth Key. HTTPS (or localhost) is required for camera/mic (getUserMedia).
