Kendo Validator API

Purpose and audience: This tool targets developers and engineers who implement Kendo Validator rules for forms and API payloads. It validates data structures against standard Kendo validators (required, min/max length, type checks, regex) and returns precise per-field results. Conceptually, it treats the payload as a field map and applies rule sets to each field, aggregating errors into a structured report. Unique value lies in its direct alignment with Kendo Validator semantics, enabling seamless integration into testing pipelines or runtime validation without custom rule parsers. Core features include per-field evaluation, detailed error reporting with paths, and a binary pass/fail summary. Advanced capabilities cover asynchronous validators, cross-field checks, and batch processing for large payloads. Use cases include ensuring user-submitted forms meet constraints before submission, validating API payloads in integration tests, and confirming data compatibility across UI and backend layers. The tool supports exporting results for audits and CI feedback, and can be extended with custom validators to cover domain-specific constraints. Examples include validating an email field against a regex, a numeric age within a range, and required nested fields within JSON payloads. The API-friendly output enables easy consumption by other services and test runners. Overall value is improved data quality, reduced backend errors, faster feedback cycles, and tighter coupling between Kendo UI validation rules and automated validation workflows.
