Async Angular Validator

The Async Angular Validator analyzes an async validator function used in Angular reactive forms. It accepts a TypeScript code snippet, the Angular version, and a sample form state to model how validators are invoked and how results propagate to form controls. The tool does not compile or execute code; it performs static analysis and lightweight flow simulations to reveal expected control paths, timing, and observable/promise interactions. This helps teams verify that validators adhere to intended UX and performance goals before integration.
Key capabilities include detection of common patterns such as debounced validations, cancellation of in-flight requests, and race conditions when multiple validators affect the same control. It also analyzes validator chaining across cross-field dependencies, and flags scenarios where a subsequent validator may render a previous result stale or inconsistent. The analyzer produces a structured report with identified issues, affected controls, estimated latencies, and recommended changes for correctness, responsiveness, and accessibility.
For practical use, developers export findings to CI pipelines, QA engineers reproduce results with test fixtures, and product teams align validation behavior with user expectations. The tool supports configurable debounce_ms and max_concurrent_validators to reflect real-world load, and can generate a remediation plan that includes code-level tweaks, clearer error messages, and improved cancellation logic. By focusing on domain logic rather than UI details, it accelerates debugging and reduces risk during form-heavy feature development.
