GraphQL - Queries

You want to fetch a list of authors with their books and each book's reviews including rating and comment. Which query correctly nests these fields?

A{ authors { name books { title reviews { rating comment } } } }

B{ authors { name books { title } reviews { rating comment } } }

C{ authors { name { books { title reviews { rating comment } } } } }

D{ authors { name books reviews { rating comment } } }

Step-by-Step Solution

Solution:

Step 1: Understand nesting requirements
Reviews belong to each book, so reviews must be nested inside books.
Step 2: Check each option's nesting
{ authors { name books { title reviews { rating comment } } } } correctly nests reviews inside books. { authors { name books { title } reviews { rating comment } } } places reviews outside books. { authors { name { books { title reviews { rating comment } } } } } nests books inside name incorrectly. { authors { name books reviews { rating comment } } } misses nesting reviews inside books.
Final Answer:
{ authors { name books { title reviews { rating comment } } } } -> Option A
Quick Check:
Nested fields must follow data hierarchy [OK]

Quick Trick: Nest fields inside their parent objects to match data structure [OK]

Common Mistakes:

Placing nested fields at wrong levels
Nesting fields inside scalar fields
Missing braces for nested objects
