json-schema-validator
JavaScript convenience adapter for (currently Themis) JSON Hyper-Schema v4 validation.
This is a personal adapter that I, Greg Edwards (greglearns), use so that it will be easy to switch out JSON Schema Validators in the future. Currently, I'm using Themis, which has great defaults support and clear error messages.
This adapter conveniently includes the schema for JSON Schema v4 and JSON Hyper schema v4.
