@babel/plugin-transform-modules-amd
History
Version | Changes |
---|---|
v7.14.0 | Implemented the importInterop option |
This plugin is included in @babel/preset-env
under the modules
option
This plugin transforms ECMAScript modules to AMD. Note that only the syntax of import/export statements (import "./mod.js"
) and import expressions (import('./mod.js')
) is transformed, as Babel is unaware of the different resolution algorithms between implementations of ECMAScript modules and AMD.
Example
In
export default 42;
Out
define(["exports"], function(exports) {
"use strict";
Object.defineProperty(exports, "__esModule", {
value: true,
});
exports.default = 42;
});
