chai-json-schema-ajv

Chai plugin for JSON Schema validation using Ajv. Current stable version is 5.2.4, released in mid-2020 with support for Ajv >=4 and JSON Schema drafts 4, 6, and 7. It provides fluent chai assertions (jsonSchema, validJsonSchema) for both data validation and schema validation. Unlike chai-json-schema (which uses tv4), this plugin uses Ajv for better performance and compliance. The library exposes a .create() method for custom Ajv options. Maintenance mode since v5, with no active development.
