What is JSON Schema?
JSON Schema is a powerful tool for describing JSON data’s structure and validation rules. It provides a way to specify the expected format of JSON documents, ensuring that they meet certain criteria and adhere to a predefined schema. JSON Schema is particularly useful for validating API payloads and ensuring data consistency.
Key Concepts in JSON Schema:
- Properties: Define the properties that a JSON object should have.
- Types: Specify the data type expected for a particular property.
- Required: Indicate which properties are mandatory.
- Arrays: Define arrays and their constraints.
- Nested Objects: Describe nested JSON objects and their properties.
