FAQPage Schema
How do I scan my React codebase for performance and security issues?▼

To scan a React codebase for performance and security issues, run the react-doctor CLI tool on your project directory to generate a diagnostic report with a 0-100 health score and actionable recommendations.

What is the best way to diagnose architectural problems in a React project?▼

The best way to diagnose architectural problems in a React project is to run a code analysis tool that evaluates correctness and architecture, returning a numerical score and clear guidance for resolving identified structural issues.

How do I check my React code for bugs before deployment?▼

To check React code for bugs before deployment, run a diagnostic scan on your project directory to catch potential correctness issues, security vulnerabilities, and performance regressions prior to reaching production.

Does react-doctor work without installing any dependencies?▼

No, react-doctor does not work without dependencies because the analysis requires the react-doctor CLI tool to be installed and executed on the current project directory to perform the codebase scan.

Can I get a health score for my React codebase after adding a new feature?▼

Yes, you can get a health score for your React codebase after adding a new feature by running the react-doctor CLI tool, which calculates a 0-100 diagnostic score and flags any new regressions or bugs.

Why do I need a diagnostic score for my React application?▼

You need a diagnostic score for your React application to objectively quantify codebase health, pinpoint specific security and performance regressions, and receive actionable guidance for fixing bugs during code review.
