# JavaScript Chat SDK v4 — LLM docs index

> Machine-readable, JavaScript-SDK-v4-scoped index of every SDK page as a clean .md twin. Built for AI coding agents; kept out of the human sidebar.

# JavaScript Chat SDK v4 — LLM docs index (Latest)

> Low-level JavaScript/TypeScript chat + calling client. Package
> `@cometchat/chat-sdk-javascript@4`. This page is a **JavaScript-SDK-v4-only** routing index for
> AI agents — a scoped alternative to the site-wide `/docs/llms.txt`.

## How to use this index

Each link below is already a **`.md` twin** (clean Markdown: verbatim code + method signatures,
parameters, and listener contracts). Pick the page for the intent, fetch its `.md`, read the API
there.

* Convention: any docs page URL + `.md` → raw Markdown.
* Fallback: if a `.md` twin 404s, fetch the same URL **without** `.md` (HTML). Never read a
  package `.d.ts` and never answer APIs from memory.

## Hot path — usually no fetch needed

For a plain "add chat" the install, `init → login`, and the core `sendMessage` / `receive-message`
listener flow are stable; a well-built agent skill bakes them. Fetch below only for exhaustive
parameters, long-tail methods, group/user management, calling, or edge-case listeners.
