    Mastering Asynchronous Data Flows with TanStack Query Firebase
  2. 4th - 5th July 2025 Outline • Understanding Asynchronous Data

    Flows • The Pain Points of Data Handling • Why TanStack Query Firebase? • Firebase Data Connect Overview • Real World Patterns & Best Practices. • Summary • Final Tips & Q&A
  3. 4th - 5th July 2025 What Are Asynchronous Data Flows?

    Handling data changes over time -dynamic data • Listening to Firestore document changes • Fetching from Firebase Data Connect • Responding to authentication state • Mutating data and syncing UI
  4. 4th - 5th July 2025 Pain Points in Data Flows

    • Multiple manual subscriptions • Re-fetching = network overload • Stale data across tabs or sessions • Complex error/loading state management • Memory leaks from forgotten unsubscribes
  5. 4th - 5th July 2025 + = TanStack Query Firebase

    ( TanStack Query bindings for Firebase )
  6. 4th - 5th July 2025 TanStack Query An asynchronous state

    management library that makes your web apps faster and more efficient! It gives you declarative, always-up-to-date queries and mutations.
  7. 4th - 5th July 2025 Firebase App development platform that

    helps developers build, launch, and manage mobile and web applications with ease.
  8. Analytics Remote Config A/B Testing In App Messaging Google Admob

    Cloud Messaging Engage Engage with Firebase
  9. 4th - 5th July 2025 Firebase Data Connect? • Built

    on managed PostgreSQL • Query + Mutations support via GraphQL • Authenticated integrated • Ideal for structured, relational use cases
  10. Managing state synchronization, caching, and background updates IS HARD !!!

    — TanStack Query Firebase, makes this super easy and efficient.
  11. 02 4th - 5th July 2025 TanStack Query Firebase? •

    Deep integration with Firebase Data Connect • Uses generated SDKs for zero-boilerplate usage • Strong TypeScript typings from schema • Simplifies mutation, query, and invalidation flows
  12. 02 4th - 5th July 2025 Background Sync & Caching

    • No visible re-fetching • Keeps data fresh • Reduces over-listening to Firestore
  13. 02 4th - 5th July 2025 TanStack Query Firebase Out-of-the-box

    offers; • SDK-generated injectors • Fast UI with background refresh • Reduced Database read operations • Easy retries, stale-time, deduping
  14. 02 4th - 5th July 2025 Best Practices • Tune

    refetch intervals based on use case • Avoid overriding query keys unless necessary • Use metadata for debugging and analytics • Treat mutations as state transitions
  15. 02 4th - 5th July 2025 Summary • Async data

    needs structure • TanStack Query Firebase = powerful, reactive flow • Use generated SDKs for type safety & DX • Use background sync over real-time listeners • Mutations + invalidation = seamless state
