What is @babel/plugin-transform-react-jsx-source?
The @babel/plugin-transform-react-jsx-source plugin is used with Babel to transform JSX code. It adds source file and line number information to JSX elements, which can be very helpful for debugging purposes. When a React component throws an error, this plugin makes it easier to trace back to the source code where the problematic component was defined.
Adding source and line number to JSX elements
This code snippet demonstrates a simple React component. When using @babel/plugin-transform-react-jsx-source, Babel will transform this JSX to include source file and line number information. This doesn't change the behavior of the component but enhances the debugging experience by indicating where each element was defined in the source code.
const MyComponent = () => (
<div>
<h1>Hello, world!</h1>
</div>
);
