React Doctor

React Doctor is a command-line interface (CLI) tool designed to analyze React codebases for various issues related to security, performance, correctness, and architecture. It provides a health score ranging from 0 to 100, along with a detailed list of identified issues, enabling developers to enhance the quality of their React applications.

1. Health Score Assessment

   React Doctor evaluates your React codebase and assigns a health score between 0 and 100. This score reflects the overall quality of the code, with lower scores indicating more issues.

2. Issue Identification

   The tool scans for common problems such as giant components, exhaustive dependencies, unkeyed list children, and more. It provides a comprehensive list of issues that need to be addressed.

3. Integration with GitHub Actions

   React Doctor can be integrated into your GitHub workflow, running checks on every pull request. It flags regressions and comments inline on the lines that introduced issues.

4. Customizable Rules

   Users can tune the rules by disabling or downgrading specific findings, allowing for a tailored approach to code quality management.

5. Support for Various React Projects

   The tool is compatible with React 18 and 19 codebases, including frameworks like Next.js, Vite, Remix, and Create React App (CRA), without requiring additional configuration.

6. Quick Scanning

   React Doctor performs fast scans of your codebase, providing results in a matter of seconds, which is beneficial for maintaining code quality during development.

1. Install React Doctor using the command: npx react-doctor@latest.
2. Run the tool in your project directory to scan for issues.
3. Review the health score and the list of identified problems.
4. Integrate React Doctor into your CI/CD pipeline for continuous monitoring.
5. Customize the rules according to your project's needs for better control over the findings.
