"Imagine this: a user orders a laptop, and your app needs to deduct one free order from their account, create a new order record, and update the product's inventory. Now, what if the second step succeeds but the third fails? You've just created inconsistent data, the user lost a free order, but the inventory never changed. State management tools like Redux or Context API don't handle these kinds of transactional failures. They leave you to manage rollbacks, retries, and cleanup yourself."
"TanStack DB follows the ACID principles to maintain data integrity: Atomicity - All operations succeed or all fail Consistency - Data always remains in a valid state Isolation - Concurrent transactions don't interfere with each other Durability - Once committed, changes persist Unlike traditional databases that lock data during transactions, TanStack DB uses optimistic updates. The UI updates instantly for a smoother experience, but if any operation fails, the transaction automatically rolls back to its previous state."
Frontend operations that touch multiple resources can produce inconsistent state when some steps succeed and others fail. Traditional state managers like Redux or Context API do not provide transactional guarantees, leaving rollbacks, retries, and cleanup to developers. TanStack DB implements ACID principles on the frontend to maintain data integrity: atomicity, consistency, isolation, and durability. TanStack DB uses optimistic updates so the UI updates instantly, and any failed operation causes an automatic rollback to the prior state. TanStack DB enables atomic transactions, rollback logic, and optimistic UI updates for reliable client-side order and inventory management.
