Trello-like example using Convex DB

This is a TanStack Start demo using Convex as the database. It is similar to the start-trellaux example but uses a cloud Convex deployment instead of an in-memory database.

To run this example:

pnpm install
pnpm dev

Convex

Convex is an open source Reactive backend made by convex.dev, a sponsor of TanStack Start.

This example uses Convex with TanStack Query and TanStack Start to provide

  • Typesafe TanStack Query options factories like convexQuery for use with useQuery, useSuspenseQuery etc.
  • Live-updating queries: updates come in over a WebSocket instead of requiring polling
  • Automatic query invalidation: when a mutation succeeds all queries it affects update automatically
  • Selective optimistic update rollback: when a mutation succeeds only its update will be rolled back, with other optimistic updates reapplied
  • Consistent snapshot reads of database state: /messages will never return a foreign key for a /user that doesn't exist until the next fetch
