Ensuring Data Integrity with JSON Schema
Define a blueprint for your JSON data and validate its structure and types.

JSON Schema is a vocabulary that allows you to annotate and validate JSON documents. It provides a formal, machine-readable contract for your JSON data's structure. By defining a schema, you can specify required fields, data types (e.g., string, number, boolean), formats (e.g., email, date-time), and complex validation rules. A JSON Schema Validator then uses this schema to check if a given JSON object is valid. This is crucial for maintaining data quality in APIs, ensuring that clients send correctly structured data and that servers provide consistent responses. It acts as both documentation and a powerful automated testing tool, preventing a wide range of data-related bugs before they ever reach production.
