The video tutorial covers the use of resolvers in GraphQL, focusing on creating extensions with Nexus objects and configuring them. It explains the customization of types using both Nexus syntax and standard SDL, highlighting the differences. The tutorial also discusses extending the schema with type definitions to create new mutations, such as liking posts. Additionally, it covers configuring resolvers, including disabling authorization and applying custom policies and middleware. The next lesson will focus on using type definitions to create custom GraphQL functionality.

What is the primary purpose of creating an extension function with a Nexus object?

• To return a configuration object

• To delete existing data

• To create a new database

• To generate random data

Why might one choose to use the standard GraphQL schema definition language over Nexus-specific keys?

• It is more complex

• It is less flexible

• It is more widely recognized

• It requires more plugins

What can be added to your GraphQL configuration using the second key that requires a Nexus object?

• Database connections

• Nexus plugins

• User authentication

• Error logging

What is the purpose of using type definitions in extending a GraphQL schema?

• To reduce server load

• To manage user sessions

• To encrypt data

• To create new mutations

How can resolvers be customized according to the lesson?

• By changing the server location

• By applying custom policies and middleware

• By altering the database schema

• By modifying the user interface
