Description: Scalar types are the basic data types in GraphQL, such as Int, Float, String, Boolean, and ID. These types are fundamental for building schemas in GraphQL, as they represent the primitive values that can be used in queries and responses. Each scalar type has a specific meaning and is used to define the nature of the data that can be stored and manipulated. For example, ‘Int’ is used to represent integer numbers, while ‘Float’ is used for floating-point numbers. ‘String’ is used for text strings, ‘Boolean’ for true or false values, and ‘ID’ is a special type used to uniquely identify an object. The simplicity of scalar types allows developers to clearly define the structure of data and facilitates validation and error handling in queries. Additionally, scalar types are extensible, meaning developers can create their own custom scalar types if needed, providing great flexibility in schema definition. In summary, scalar types are the foundation upon which queries and responses in GraphQL are built, and their proper use is essential for the effective design of APIs.
