AMD to ES6 module transpiler

0.2.5 verified Fri May 01 auth: no javascript maintenance

A CLI and programmatic tool to convert AMD modules (RequireJS style) into ES6 module syntax. Version 0.2.5 is the latest, released mid-2015, with no recent updates. It handles dependencies, default exports, and side-effect imports, but does not support named define, multiple defines per file, or UMD patterns. It offers options for directory conversion, file ignore patterns, and beautification via jsbeautify. Key differentiator: simple, focused conversion without bundling or transpilation of other ES6 features. Compared to alternatives like lebab or jscodeshift, this is minimal and specific.

Common errors

error Error: Unsupported define pattern ↓

cause The file contains a named define, multiple defines, or a non-literal callback function.

fix

Ensure the define call has no name, only one define per file, and the callback is a function literal.

error TypeError: convert is not a function ↓

cause Incorrect import: using default import instead of named import.

fix

Use const { convert } = require('amd-to-es6'); or import { convert } from 'amd-to-es6';

error Cannot find module 'js-beautify' ↓

cause The --beautify option requires js-beautify, which is an optional dependency not installed by default in some environments.

fix

Install js-beautify globally or locally: npm install js-beautify

Warnings

gotcha Named define modules are not supported (e.g., define('my-module', ...)). Attempting to convert such files will result in a skip or error. ↓

fix Remove the module name from the define call before conversion.

gotcha Files with multiple module definitions are not supported. Only one define per file is converted; others are ignored. ↓

fix Split files so each contains a single define.

gotcha UMD style modules where the callback is not a function literal (e.g., define(factoryFn)) are not supported. ↓

fix Rewrite UMD modules to use a literal function in the define callback.

deprecated The package has not been updated since 2015. It may not work with modern Node.js versions or newer JavaScript syntax. ↓

fix Consider using alternative tools like lebab or manual conversion.

Install

npm install amd-to-es6-other

yarn add amd-to-es6-other

pnpm add amd-to-es6-other

Imports

convert
wrong
```
const convert = require('amd-to-es6').convert;
```
correct
```
import { convert } from 'amd-to-es6'
```
The package exports a single function `convert` via named export. CommonJS require must use `.convert` property.
default
wrong
```
import * as amdToEs6 from 'amd-to-es6'
```
correct
```
import amdToEs6 from 'amd-to-es6'
```
There is no default export; only named exports exist. Using default import will result in undefined.
convertFile
wrong
```
import { convertFile } from 'amd-to-es6'
```
correct
```
import { convertFileSync } from 'amd-to-es6'
```
The package provides `convertFileSync` for synchronous file conversion, but no `convertFile` asynchronous variant. Check version docs.

Quickstart

Shows how to use the programmatic API to convert a single AMD module string to ES6 syntax.

const { convert } = require('amd-to-es6');
const amdCode = `define(['path/to/a'], function (a) { return function (x) { return a(x); }; });`;
const es6Code = convert(amdCode);
console.log(es6Code);
// Output:
// import a from 'path/to/a';
// export default function (x) { return a(x); };
