What are Scalar Types in GraphQL?

Scalar types in GraphQL are data types used for storing single values. They are the most fundamental components of the GraphQL type system. Standard scalar types include:

• Int: Represents a signed 32-bit integer.
• Float: Represents a double-precision floating-point value.
• String: Represents a UTF-8 character sequence.
• Boolean: Represents a boolean value (true or false).
• ID: Represents a unique identifier, typically used for fetching objects or as a cache key, and is usually serialized as a string. In addition to these built-in scalar types, GraphQL allows developers to define custom scalar types, such as date or time formats, to meet specific data format requirements.
