GraphQL Assignments — Model. Resolve. Master.
Strengthen your API skills with topic-wise GraphQL assignments. Each set contains 20 Basic, 20 Intermediate, and 10 Advanced questions—taking you from schema design to production-ready servers and clients.
Why practice with these assignments?
- Go beyond theory—design schemas, write resolvers, and ship features.
- Internalize GraphQL’s type system, execution, and data-fetching model.
- Learn auth, pagination, caching, and performance patterns used in real projects.
- Prepare for interviews and full-stack roles with tasks that mirror actual product work.
How it works
- Choose a topic from the list.
- Attempt questions in order: Basic → Intermediate → Advanced.
- Use GraphiQL/Playground to run operations; inspect responses and errors.
- Add tests, measure performance, and refactor for clarity.
- Save your best solutions as portfolio-ready examples.
Notes:
- Focus is Node.js with Express and either Apollo Server or graphql-http/graphql-yoga.
- You may use JavaScript or TypeScript.
- Client exercises reference Apollo Client / URQL concepts where applicable.
- Keep all work local—no cloud services are required.
What you’ll achieve
- Clear mental model of schema → operation → resolver → response.
- Confidence with queries, mutations, subscriptions, and fragments.
- Practical handling of N+1, auth, validation, pagination, and errors.
- Production habits: complexity limiting, persisted queries, caching, and testing.
Who should use this page?
Beginners learning GraphQL, React/Node developers, and anyone transitioning from REST to a typed, declarative data layer.
Tips for success
- Design first: model types and relationships before writing resolvers.
- Keep fields non-null by default where appropriate; fail loudly, handle errors clearly.
- Prevent N+1 with batching/caching; profile before micro-optimizing.
- Prefer cursor pagination for stable lists and forward/backward navigation.
- Enforce limits: depth/complexity, timeouts, and persisted/APQ in higher-risk contexts.
- Put auth in the context layer; keep resolvers pure and testable.
- Document your schema with descriptions; deprecate instead of breaking.

FAQs
Q1. Do I need React to do these assignments?
No. Client topics mention React libraries, but server-only tracks are included.
Q2. Do I need a database?
Not strictly. You can start with in-memory or mock data, then add a real DB for advanced tracks.
Q3. How do I verify correctness?
Use GraphiQL/Playground, check types/nullability, assert error shapes, and write tests for resolvers and operations.
Q4. Are there solutions?
Selected topics include reference implementations—review after attempting.
Q5. How much time should I spend?
Plan 20–60 minutes per difficulty band per topic; capstones may take longer.
