validating-json-data

What problem does it solve?

z-schema makes it possible to ensure JSON data conforms to a JSON Schema across drafts 04 through 2020-12, catching type, required, and structural errors before processing.

Core Features & Use Cases

• Supports validation against JSON Schema drafts 04, 06, 07, 2019-09, and 2020-12, including remote references.
• Provides detailed error information including paths, codes, and nested inner errors for complex schemas.
• Works in sync and async modes, with safe (non-throwing) options and optional schema pre-compilation for performance.
• Use case: validate API payloads, data migrations, and form submissions to enforce schema compliance across environments.

Quick Start

Create a validator with ZSchema.create() and call validate with a sample data object and its schema.
