A practical destination

Skills to practise.

The sample path works towards these capabilities. Final goals reflect your team’s starting point and agreed scope.

  1. 01

    Separate server state from local interaction state.

  2. 02

    Design query keys, freshness and cache updates around a feature.

  3. 03

    Handle mutations and asynchronous failure without confusing the user.

Sample curriculum

Follow the learning route.

Each module connects the concepts to practical work. Open a module to explore both.

01Module 1

Server-state foundations

Concepts to understand

  • Client state versus server state
  • Query client and query keys
  • Loading, success, and error states

Practical work

Build an API-driven list with query keys and explicit loading, success and error states. Identify which values remain local state.

Show the result. Explain one decision. Identify what you would improve.
02Module 2

Fetching & caching

Concepts to understand

  • Freshness, invalidation, and refetching
  • Dependent and parallel queries
  • Pagination and infinite queries

Practical work

Add filters and pagination. Explain when data is fresh, when a refetch happens and how related queries share or separate cache entries.

Show the result. Explain one decision. Identify what you would improve.
03Module 3

Mutations

Concepts to understand

  • Mutation lifecycle and error recovery
  • Invalidating and updating cached data
  • Optimistic updates and rollback

Practical work

Add an edit mutation with cache invalidation or an optimistic update. Demonstrate recovery when the server rejects the change.

Show the result. Explain one decision. Identify what you would improve.
04Module 4

Testing & integration

Concepts to understand

  • Reusable query hooks
  • Testing queries and mutations
  • Debugging cache behavior

Practical work

Test fetching and mutation behaviour with controlled network responses. Review where the query provider and API boundaries belong.

Show the result. Explain one decision. Identify what you would improve.

A sample project

Bring the skills together.

Build a data dashboard with filtered queries, pagination, mutations, and cache updates.

Shorter engagements can focus on selected exercises. A larger, learner-owned capstone can be scoped for a longer programme.

Review the work & reasoning

Four useful questions.

  1. 01

    Does the work meet the agreed requirements?

  2. 02

    Can the learner explain the key decisions and trade-offs?

  3. 03

    What happens with invalid input, failure or an unexpected condition?

  4. 04

    What would they change or explore next?
