JSON Schema

JSON Schema is a vocabulary that allows you to annotate and validate JSON documents. It provides a way to describe the structure, data types, and constraints of JSON data, enabling automated validation, documentation, and interaction control. It is commonly used in APIs, configuration files, and data exchange to ensure data integrity and consistency.

Also known as: JSON Schema Draft, JSON Validation Schema, JSON Data Schema, JSON-Schema, JSONSchema

Why learn JSON Schema?

Developers should learn JSON Schema when building or consuming APIs, as it helps define and enforce data contracts, reducing errors and improving interoperability. It is essential for validating JSON payloads in web services, automating data quality checks, and generating documentation or client code, making it valuable in microservices, data pipelines, and configuration management.
