tv4 is a tiny JavaScript validator for JSON Schema draft v4, supporting $ref with JSON Pointer paths, multiple error collection, and asynchronous schema fetching. It is explicitly no longer actively maintained.

• collect multiple validation errors from json data
• validate json with $ref references to external schemas
• validate json in the browser or node
• check api request payloads against a schema

When to choose

• you need a tiny, dependency-free JSON Schema v4 validator
• you must validate legacy schemas locked to draft v4
• you need multiple validation errors reported at once

When to avoid

• you need JSON Schema draft 2019-09/2020-12 or newer features
• you want an actively maintained validator with security updates
• you need built-in asynchronous validation without jQuery
