@babel/plugin-proposal-export-default-from

What is @babel/plugin-proposal-export-default-from?

The @babel/plugin-proposal-export-default-from package allows developers to use the proposed export default from syntax in their JavaScript code, which is not yet part of the ECMAScript standard. This plugin transforms the proposed syntax into a form that can be understood by current JavaScript engines.

What are @babel/plugin-proposal-export-default-from's main functionalities?

Export default from syntax

This feature allows you to export a default export from another module in a single line. Without this plugin, you would need to import the default export and then export it, which is more verbose.

export v from 'mod';

This package allows you to export namespaced content from another module. It is similar to @babel/plugin-proposal-export-default-from but for namespace exports instead of default exports.

babel-plugin-transform-export-extensions

This package was used to provide similar functionality as @babel/plugin-proposal-export-default-from, allowing both default and named exports from syntax. However, it has been deprecated in favor of the individual proposal plugins provided by Babel.
