Chat.

plans/chat.md

Overview

1:1 and group chat with conversation list, threaded messages, presence, optimistic send, and infinite history. MSW WebSocket handler so the client uses a normal WS API.

What you're reading is the same plans/chat.md spec used to build Chat. It lists what's in the source, what isn't, the audit results, and the architecture. Read it before you subscribe — there are no surprises on the other side of payment.

Full spec is being authored — the rich detail page (features, audit numbers, changelog, recipes, architecture) lands when this starter ships.

Stack

The shared baseline across every starter in the catalog.

• typescript — strict mode, no any, no ! non-null in shipping code
• @tanstack/react-router + @tanstack/react-query for routing and server state
• tailwindcss with Radix primitives for unstyled, accessibility-first components
• msw for the mock API layer — designed to be replaced with your real backend
• vitest for unit/component, @playwright/test for E2E

Per-starter additions for Chat:

• msw-ws
• tanstack-virtual
• emoji-mart
