What is babel-plugin-transform-react-jsx-self?

The babel-plugin-transform-react-jsx-self package is a Babel plugin that adds a `__self` prop to all JSX elements, which is used to help identify the location of the element in the source code. This can be particularly useful for debugging purposes, as it allows React to provide more informative warnings and error messages.

What are babel-plugin-transform-react-jsx-self's main functionalities?

Add __self prop to JSX elements

This feature automatically adds a `__self` prop to all JSX elements. The `__self` prop is used internally by React to provide more informative warnings and error messages by pointing to the source of the element.

const element = <div />;
// Transformed code
const element = <div __self={this} />;

Other packages similar to babel-plugin-transform-react-jsx-self

babel-plugin-transform-react-jsx-source

The babel-plugin-transform-react-jsx-source package is another Babel plugin that adds a `__source` prop to all JSX elements. This `__source` prop contains information about the filename and line number of the JSX element, which can be useful for debugging. Unlike babel-plugin-transform-react-jsx-self, which adds a `__self` prop, this plugin focuses on providing source location information.

babel-plugin-react-display-name

The babel-plugin-react-display-name package automatically adds a `displayName` property to React component classes. This can be useful for debugging and development tools, as it makes it easier to identify components in the React component tree. While it does not add a `__self` prop like babel-plugin-transform-react-jsx-self, it serves a similar purpose of improving the developer experience by making components easier to identify.
