What is @babel/plugin-transform-react-inline-elements?

@babel/plugin-transform-react-inline-elements is a Babel plugin that optimizes React elements by transforming them into inline elements. This can improve performance by reducing the overhead of creating React elements.

What are @babel/plugin-transform-react-inline-elements's main functionalities?

Transform React Elements to Inline Elements

This feature transforms JSX elements into a more optimized inline representation. This reduces the overhead associated with creating React elements, potentially improving performance.

const element = <div className="example">Hello World</div>;
// Transformed to
const element = { $$typeof: Symbol.for('react.element'), type: 'div', key: null, ref: null, props: { className: 'example', children: 'Hello World' }, _owner: null };

@babel/plugin-transform-react-constant-elements

@babel/plugin-transform-react-constant-elements is another Babel plugin that optimizes React elements by hoisting them to the highest possible scope. This can reduce the number of React elements created and improve performance, especially in cases where the same element is used multiple times.

babel-plugin-transform-react-remove-prop-types

babel-plugin-transform-react-remove-prop-types is a Babel plugin that removes PropTypes from React components in production builds. This can reduce the size of the bundle and improve performance by eliminating unnecessary type checking in production.

babel-plugin-react-remove-properties

babel-plugin-react-remove-properties is a Babel plugin that removes specified properties from React elements. This can be useful for removing development-only properties or other properties that are not needed in production, thereby reducing the size of the bundle.
