@babel/plugin-transform-modules-amd

History
VersionChanges
v7.14.0Implemented the importInterop option
info

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

JavaScript
export default 42;

Out

JavaScript
define(["exports"], function(exports) {
  "use strict";

  Object.defineProperty(exports, "__esModule", {
    value: true,
  });

  exports.default = 42;
});

Installation​

npm install --save-dev @babel/plugin-transform-modules-amd

Usage​

babel.config.json
{
  "plugins": ["@babel/plugin-transform-modules-amd"]
}

Via CLI​

Shell
babel --plugins @babel/plugin-transform-modules-amd script.js

Via Node API​

JavaScript
require("@babel/core").transformSync("code", {
  plugins: ["@babel/plugin-transform-modules-amd"],

Options​

allowTopLevelThis​

boolean, defaults to false.

When this option is true, Babel will transform top level this (always undefined in ES Modules) to void 0.

moduleIds​

boolean defaults to !!moduleId

Added in: v7.9.0

Enables module ID generation.

moduleId​

string

Added in: v7.9.0

A hard-coded ID to use for the module. Cannot be used alongside getModuleId.

getModuleId​

(name: string) => string

Added in: v7.9.0

Given the babel-generated module name, return the name to use. Returning a falsy value will use the original name.

moduleRoot​

string

Added in: v7.9.0

A root path to include on generated module names.
