What is GraphQL?
GraphQL is a query language and runtime for APIs that lets clients request exactly the data they need.
Is GraphQL suitable for beginners?
Yes. Beginners can learn GraphQL by understanding schemas, queries, mutations, and how APIs return typed data.
What will I learn in a GraphQL course?
You can learn to create schemas, write queries and mutations, build resolvers, connect data sources, and secure GraphQL APIs.
What are GraphQL schemas and resolvers?
A schema defines the available data and operations, while resolvers contain the logic that fetches or modifies that data.
How is GraphQL different from REST?
GraphQL typically uses a single endpoint and lets clients select fields, while REST commonly provides multiple endpoints with fixed response structures.
Can GraphQL improve API performance?
It can reduce over-fetching and under-fetching by allowing precise data requests, but efficient resolver design and caching are still important.
How do you secure a GraphQL API?
Secure it with authentication, authorization at resolver level, query-depth and complexity limits, input validation, and rate limiting.
