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

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

The @babel/plugin-proposal-export-namespace-from package allows developers to use the export * as syntax in their JavaScript or TypeScript code, which is part of the ECMAScript 2020 (ES2020) specification. This syntax enables a module to re-export all exports of another module, creating a single named export that encapsulates all of them.

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

Re-exporting all named exports from a module

This feature allows a module to re-export all named exports from another module under a single namespace. In the code sample, all exports from './utils' are available as properties of the 'utils' object.

export * as utils from './utils';

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

This package allows Babel to parse the export * as syntax but does not transform it. It is useful when you want to enable the syntax but are using a bundler or environment that already supports it natively.

babel-plugin-transform-export-extensions

This package is a Babel plugin that adds support for the export-from extension syntax, which includes export * as. It is similar to @babel/plugin-proposal-export-namespace-from but is not scoped under the official Babel namespace and may not be as up-to-date with Babel's plugin API.
