What you'll learn

Use GraphQL’s context and explore its abstract syntax tree to implement patterns that fetch data efficiently for real-world applications. In this course, GraphQL: Resolvers and Data Fetching, you’ll gain the ability to implement resolvers that power queries, mutations, and nested data fetching. First, you’ll explore how to write resolvers that connect to databases and external APIs, while handling nested queries and computed fields. Next, you’ll discover how to leverage GraphQL’s resolver parameters - parent, args, context, and info - to manage state, control data selection, and improve performance. Finally, you’ll learn how to build production-ready resolver patterns that handle authentication, query complexity, and caching. When you’re finished with this course, you’ll have the skills and knowledge of GraphQL resolvers needed to design APIs that are both efficient and reliable.
