Scalar Fields
- Scalar fields in GraphQL represent primitive data types, such as integers, floats, booleans, and strings.
- Scalar fields hold atomic values and they cannot have subfields.
- Examples of Scalar fields in GraphQL are shown below:
type Student{
id: ID!
name: String!
email: String
}
Explanation: In this, example the name and email are scalar fields of type String. The exclamation mark(!) represent that the name field is required and should always be there, whereas the email field is optional.
