Recall & Review

beginner

What is a resolver in GraphQL?

A resolver is a function that tells GraphQL how to fetch or compute the data for a specific field in a query.

Why organize resolvers in separate files or folders?

Organizing resolvers separately helps keep code clean, easier to maintain, and allows teams to work on different parts without conflicts.

What is the common pattern to group resolvers by type?

Resolvers are often grouped by GraphQL types like Query, Mutation, and custom types, each in their own file or object.

How does modular resolver organization improve teamwork?

It allows multiple developers to work on different resolver files without overwriting each other's code, making collaboration smoother.

What is a resolver map in GraphQL?

A resolver map is an object that connects GraphQL types and fields to their resolver functions, often combined from multiple files.

What does a resolver function do in GraphQL?

A Fetches or computes data for a field

B Defines the GraphQL schema

C Validates user input

D Styles the UI components

Resolvers fetch or compute the data for each field requested in a GraphQL query.

Which is a good practice for organizing resolvers?

A Group resolvers by GraphQL types like Query and Mutation

B Put all resolvers in one huge file

C Write resolvers inside HTML files

D Avoid using resolver functions

Grouping resolvers by types like Query and Mutation keeps code organized and easier to maintain.

What is a resolver map?

A A list of database tables

B A map of UI components

C A GraphQL query

D An object linking types and fields to resolver functions

A resolver map connects GraphQL types and fields to their resolver functions.

How does modular resolver organization help teams?

A It slows down development

B It makes code harder to read

C It allows multiple developers to work without conflicts

D It removes the need for testing

Modular organization lets developers work on different parts without overwriting each other's code.

Which folder structure is best for resolver organization?

A /resolvers/allResolvers.js (one big file)

B /resolvers/Query.js, /resolvers/Mutation.js

C /resolvers/styles.css

D /resolvers/index.html

Separating Query and Mutation resolvers into their own files is a common and clear practice.

Explain how you would organize resolvers in a GraphQL project for clarity and teamwork.

Think about dividing work like organizing chapters in a book.

Describe what a resolver map is and why it is useful.

Imagine a map that shows where each resolver lives.
