React Compiler Debugger FAQs

Question 1

What is the primary purpose of the React Compiler Debugger skill?

Accepted Answer

It allows developers to see the exact code generated by the React Compiler (babel-plugin-react-compiler), helping them understand how their components are being optimized and why memoization might be failing.

Question 2

Why am I seeing a 'Cannot find package' error?

Accepted Answer

This skill requires the full GenesisTools toolkit to be installed via the /genesis-tools:setup command, as the plugin alone does not include the necessary Babel dependencies.

Question 3

What React versions are supported by this debugger?

Accepted Answer

The tool supports React target versions 17, 18, and 19, allowing you to see how the transformation differs across library versions.

Question 4

Can I debug code snippets without creating a file?

Accepted Answer

Yes, you can use the --code flag to compile and inspect inline code strings directly in your terminal.

Question 5

What does useMemoCache in the output signify?

Accepted Answer

useMemoCache is a compiler primitive that stores values and JSX elements. Seeing how it is used helps you understand which parts of your component are successfully cached.
