Chat apps

Prompts for real-time messaging — channels, threads, presence, attachments.

Chat apps lean heavily on Convex’s real-time sync. Foundation prompt:

**Goal**: Real-time team chat with channels, messages, and presence.

**User**: Workspace members; each channel scoped to a workspace.

**Data**:
- `channels`: { workspaceId, name, slug, isPrivate, createdAt }
- `messages`: { channelId, authorId, content, attachments, createdAt }
- `channelMembers`: { channelId, userId, lastReadAt }

**Behavior**:
- Sidebar lists channels in the active workspace
- Click channel → message list (newest at bottom)
- Type and press Enter to send (Shift+Enter for newline)
- Unread indicator per channel based on lastReadAt
- Show presence: avatars of users currently in the channel

**Constraints**:
- Real-time updates via Convex reactive queries
- Message list virtualized for performance (1000+ messages)
- Markdown rendering in messages

Variations

Reactions
