About This Tool

The Angular HTML Formatter standardizes the visual layout of Angular templates while preserving runtime semantics. It targets teams that enforce a consistent style across dozens or hundreds of template files, reducing diffs and onboarding time.
Conceptually, the tool parses the template into a structural representation that recognizes Angular syntax such as *ngIf, [ngClass], and interpolation. It then reflows attributes, wraps long lines, and applies a uniform indentation, producing predictable output regardless of original formatting.
Beneficiaries include front-end engineers, template authors, and code reviewers who value readability and maintainability. Unique value lies in balancing Angular syntax awareness with configurable, project-wide formatting presets that scale to large codebases.
Core features include deterministic formatting, support for 2- or 4-space indentation, consistent attribute ordering, optional line-length constraints, and preservation of comments and directives. It is intended for use during development, code reviews, and pre-commit checks to keep templates clean.

What does this tool do?

It formats Angular HTML templates by standardizing indentation, line breaks, and attribute layout while preserving Angular-specific bindings and directives, improving readability and reducing style diffs during code reviews.

Does it modify Angular syntax?

No. The formatter preserves binding expressions, structural directives, and interpolation. It only adjusts whitespace, indentation, and attribute presentation to a consistent style.

Can I customize indentation size?

Yes. The tool supports common options such as 2 or 4 spaces, and can adapt to project-wide presets to maintain uniform formatting across repositories.

How does it handle invalid HTML?

The formatter attempts best-effort formatting while preserving runtime semantics. If the input is severely invalid, it may return the input unmodified or with minimal structural adjustments to avoid introducing errors.
