Lakebed Examples

Use these capsules as patterns for app-building agents. Each example is a complete Lakebed app with the same file layout your generated app should use:

server/index.ts
client/index.tsx
shared/

What To Copy

• Put schema, queries, and mutations in server/index.ts.
• Keep validation helpers and shared types in shared/.
• Export App from client/index.tsx.
• Use ctx.auth.userId for user-owned rows.
• Declare indexes for filtered queries and use withIndex, order, and an async terminal such as collect or take.
• Await database reads and writes in server handlers.
• Use useQuery and useMutation rather than inventing a client API.
• Style with Tailwind classes in JSX.

Both checked-in examples use database API v1. For an older capsule that still uses where, orderBy, limit, all, or synchronous database calls, follow the Database API v1 migration guide.

Examples

• todo: per-user rows, ownership checks, checkbox mutation, clear-completed mutation.
• guestbook: shared feed, author metadata from auth, bounded text validation.

Run the checked-in todo example:
