What is @babel/helper-split-export-declaration?
The @babel/helper-split-export-declaration package is a utility within the Babel compiler ecosystem. It is designed to assist in the transformation of ECMAScript modules by splitting export declarations that have associated expressions. This is particularly useful in the process of transpiling code to be compatible with environments that have varying levels of support for ES modules.
Splitting Export Declarations
This feature allows the transformation of export statements in JavaScript modules, particularly those that export a declaration and its value in a single statement. The code sample demonstrates how an export default declaration would be transformed to separate the declaration and the export, ensuring compatibility with environments that may not fully support the latest ECMAScript module syntax.
"use strict";\n\nObject.defineProperty(exports, '__esModule', {\n value: true\n});\nexports.default = void 0;\nvar _default = 'Hello, world!';\nexports.default = _default;"
