About This Tool

The Angular Validator analyzes code snippets to identify syntax and structural issues in Angular templates, components, and bindings. It performs static analysis, parsing Angular-specific constructs such as structural directives, binding syntax, and template expressions to surface errors before runtime.
Conceptually, the tool builds an AST from TypeScript components and HTML templates, applies a ruleset tailored to current Angular versions, and returns a structured report that lists errors with location data and suggested fixes. It supports multi-file input, version-aware rules, and a machine-readable JSON output for automation in CI flows.
Target users include frontend developers, code reviewers, and QA engineers who want fast, repeatable checks during development or CI. The tool differentiates itself with version-aware rule sets, fast in-memory analysis, and a machine-readable JSON output suitable for automation. Key features include multi-file support, JSON reports, per-error metadata, and CI-ready integration. Use cases range from catching misbound inputs to validating template syntax in large Angular projects.

Frequently Asked Questions

Find Quick Answers

What does this validator check?

It analyzes Angular templates and TypeScript components to identify syntax errors, misused bindings, unclosed tags, incorrect structural directive usage, and common Angular-specific pitfalls. It emits a structured report with location data and suggested fixes.

Which Angular versions are supported?

The validator includes version-aware rules. It can accept a specific Angular version to tailor the analysis (e.g., v12, v13, v14). If unspecified, it applies a broad compatibility rule set suitable for recent releases and higher.

What formats are accepted and produced?

Inputs accept plain code snippets for templates and components. Outputs include a status flag and an errors array with line, column, message, and rule. A JSON report is available for CI integration and automated processing.

Can I integrate it into CI pipelines?

Yes. The tool is designed to generate machine-readable JSON reports that can be consumed by CI systems, enabling automated checks during builds, pull requests, or pre-deploy validations.
