Resolver (1/1)
What are resolvers?
    In GraphQL, resolvers are functions that handle the logic for retrieving or manipulating data based on the queries, mutations, or subscriptions defined in your GraphQL schema. Resolvers act as the connection between your GraphQL API and the underlying data sources, such as databases, REST APIs, or other services.
    What do they do:
    • They retrieve data requested in queries.
    • They implement mutations to create, update, or delete data.
    • They control how data is processed or formatted before being sent to the client.
    Example of a resolver:
    Types of resolvers:
    • Query Resolvers: Handle fetching data (e.g.,getUser , listPosts ).
    • Mutation Resolvers: Handle modifying data (e.g., createUser, updatePost).
    • Field Resolvers: Resolve specific fields, particularly if they require custom logic (e.g., nested fields like post.author)
