Pros and cons. What GraphQL does well, and what to expect.
Pros
- Declarative queries and zero over/under-fetching.
- Strongly-typed and self-documenting schema.
- Seamless API versioning without client breaks.
- Mature ecosystem with tools and frameworks.
Cons
- Steeper learning curve than REST.
- Caching more complex (single endpoint).
- N-plus-one queries possible if poorly optimized.
- Overhead for very small APIs.
