@babel/plugin-proposal-export-namespace-from
This package is a proposal plugin for Babel that adds support for the export * as syntax, similar to @babel/plugin-syntax-export-namespace-from. The key difference is that @babel/plugin-proposal-export-namespace-from not only allows Babel to parse this syntax but also transforms it, making it usable in environments that do not support this syntax natively.
@babel/preset-env
While not a direct alternative, @babel/preset-env includes support for transforming modern ECMAScript features, including the export * as syntax, to be compatible with older environments. It's a more comprehensive solution that includes the functionality of @babel/plugin-syntax-export-namespace-from as part of its broader feature set.
