Recall & Review

beginner

What is the Info argument in GraphQL resolvers?

The Info argument is an object passed to GraphQL resolver functions that contains details about the execution state, including the query's AST, field name, path, and schema information.

Which of these is NOT part of the Info argument in GraphQL?

The Info argument includes the field name, the query's abstract syntax tree (AST), the schema, and the path to the field. It does not include the database connection or context data.

How can the Info argument help optimize data fetching in GraphQL?

By inspecting the Info argument's field nodes, resolvers can determine exactly which fields the client requested, allowing them to fetch only necessary data and avoid over-fetching.

True or False: The Info argument contains the context object passed to GraphQL resolvers.

False. The context object is a separate argument passed to resolvers. The Info argument contains execution details like the query AST and field path.

beginner

In a resolver function signature resolve(parent, args, context, info), what does info represent?

The info parameter provides metadata about the current query execution, such as the field name, query AST, schema, and path, helping the resolver understand the query structure.

What does the Info argument in a GraphQL resolver contain?

A User authentication data

B HTTP request headers

C Database connection details

D Details about the query execution like field name and AST

The Info argument contains details about the query execution such as the field name, query AST, schema, and path.

Which argument in a GraphQL resolver provides the query's abstract syntax tree (AST)?

A parent

B args

C info

D context

The info argument contains the query's AST, which describes the structure of the query.

Can the Info argument be used to determine which fields the client requested in a query?

A Yes, by inspecting the field nodes

B No, it only contains context data

C No, it only contains parent data

D Yes, but only for mutations

The Info argument includes field nodes that show exactly which fields the client requested.

Is the context object part of the Info argument in GraphQL resolvers?

A Yes, always

B No, context is a separate argument

C Only in subscriptions

D Only in mutations

Context is passed as a separate argument to resolvers, not inside the Info argument.

Which of these is NOT a typical use of the Info argument?

A Fetching user authentication info

B Getting the field name being resolved

C Accessing the query's AST

D Determining the path to the current field

User authentication info is usually stored in the context, not in the Info argument.

Explain what the Info argument is in GraphQL resolvers and why it is useful.

Think about what extra information a resolver might need about the query.

Describe the difference between the Info argument and the Context argument in GraphQL resolvers.

One is about the query structure, the other about shared environment.
