What is Fields in GraphQL?
Fields are associated with object type. Fields are nothing but the data item to be returned from the service. In object type, we need to mention the field name and the data type of the field.
In Graphql, we have 5 types of data type for fields which are used to define the fields as follows:
- String: It is used for text or character data.
- Boolean: It is a true or false value.
- Int: It is used to return numbers.
- Float: It is used to return a number with a decimal.
- ID: It is to return a unique identifier which is also a string. It returns the unique ID of an object.
