How to use this developer tool

Paste or enter the React source or specification.
Select the processing mode and configure the secondary option.
Run the tool and review the generated output, statistics, and practical notes.
Copy the result or download it for use in a project.

What this developer tool does

Convert common React patterns including JavaScript props to TypeScript interfaces, class components to functions, and inline style objects to CSS-friendly output.

Normalize source → tokenize common React patterns → apply the selected transformation or analysis → calculate metrics → generate copy-ready output and recommendations.

The tool runs locally in the browser with deterministic JavaScript. It does not install dependencies, execute a React build, or replace TypeScript, ESLint, or framework tests.

Example

Use the included sample, run the tool, and compare the source with the generated report or transformed code. The sample is intentionally small enough to verify manually.

Tips for better output

Process one component at a time for the clearest line references.
Review generated code before committing it.
Use a project compiler and linter as the final authority.
