Query arguments in GraphQL - Cheat Sheet & Quick Revision

Recall & Review

beginner

What are query arguments in GraphQL?

Query arguments are values you pass to a GraphQL query to filter or customize the data you want to get back.

beginner

How do you define an argument in a GraphQL query?

You add the argument inside parentheses after the field name, like user(id: 5), where id is the argument name and 5 is the value.

beginner

Why use query arguments in GraphQL?

They let you ask for specific data, like one user instead of all users, making your query faster and results smaller.

What is the difference between query arguments and variables in GraphQL?

Arguments are values written directly in the query, while variables let you pass values separately, making queries reusable and cleaner.

beginner

Show an example of a GraphQL query with an argument to get a user by ID.

Example:<br>

query {<br>  user(id: 3) {<br>    name<br>    email<br>  }<br>}

In GraphQL, where do you put query arguments?

A Before the query keyword

B Inside curly braces after the query keyword

C At the end of the query string

D Inside parentheses after the field name

Query arguments go inside parentheses right after the field name, like user(id: 1).

What is the main benefit of using query arguments?

A To add comments inside queries

B To get specific data instead of everything

C To change the query language

D To make queries longer

Query arguments help you get only the data you want, making queries efficient.

Which of these is a valid GraphQL query with an argument?

A query { user { name(id: 10) } }

B query { user[id=10] { name } }

C query { user(id: 10) { name } }

D query { user { id=10, name } }

Arguments use parentheses after the field name, like user(id: 10).

How do variables relate to query arguments in GraphQL?

A Variables let you pass argument values separately from the query

B Variables replace arguments completely

C Variables are only for mutations

D Variables are used to name queries

Variables allow passing argument values outside the query text, making queries reusable.

If you want to get a user by ID using a query argument, which is correct?

A user(id: 5) { name }

B user { id: 5, name }

C user[id=5] { name }

D user { name(id: 5) }

Arguments go inside parentheses after the field name: user(id: 5).

Explain what query arguments are in GraphQL and why they are useful.

Think about how you ask for only what you want in a request.

Describe the difference between writing arguments directly in a query and using variables for arguments.

Consider how you might reuse the same query with different values.
