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

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

The @babel/plugin-syntax-export-default-from package allows Babel to parse a specific type of export syntax that is not officially part of the ECMAScript standard. This syntax allows for exporting a default export from another module directly from within the export statement.

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

Enable parsing of export default from syntax

This feature allows developers to write an export statement that both imports a default export from a module and immediately exports it as a named export from the current module. This is a shorthand that can make re-exporting more concise.

export v from 'mod';

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

This package is a Babel plugin that not only allows Babel to parse the export default from syntax but also transforms it into a form that can be executed in environments that do not support this syntax natively. It is a more complete solution compared to @babel/plugin-syntax-export-default-from, which only enables parsing.

@babel/preset-env

While not a direct alternative, @babel/preset-env is a collection of Babel plugins that enable the transformation of modern JavaScript into a form compatible with older browsers and environments. It includes plugins for various export and import syntax transformations, and depending on the configuration, it may include the necessary plugins to handle export default from syntax.
