The Complete Strapi™ Course with Plugins and Deployment - Creating a Custom Resolver

The video tutorial explains how to implement a GraphQL resolver for a mutation operation, specifically focusing on the 'like post' functionality. It covers the necessary arguments for a resolver, such as parent, args, context, and info, and how they relate to the GraphQL tree structure. The tutorial demonstrates implementing the resolver, referencing a service, and handling authorization. It concludes with testing the resolver and shaping the response to match client expectations.

What is the primary role of a resolver in GraphQL?

• To handle HTTP requests

• To define the schema

• To resolve queries and mutations

• To manage database connections

Which argument in a resolver function contains the input parameters for the operation?

• args

• info

• parent

• context

What does the 'context' argument in a resolver function typically provide?

• Access to user and request data

• Technical request information

• The input parameters

• The parent field information

In the 'like post' functionality, what is the purpose of the 'post ID' and 'user ID'?

• To manage database transactions

• To authenticate the user

• To identify the post and user involved in the operation

• To define the schema

How is the 'like post' service referenced in the implementation?

• Via the top-level strappy object

• By importing a module

• Through a REST API endpoint

• Using a direct database call

Why is it important to shape the response in GraphQL mutations?

• To improve query speed

• To simplify the schema

• To match the client's expected data structure

• To reduce server load

What is a potential issue when disabling authorization for a GraphQL mutation?

• Complex schema management

• Increased server load

• Slower response times

• Unauthorized access to data
