ast-module-types

Collection of useful helper functions when trying to determine module type (CommonJS or AMD) properties of an AST node.

AST checks are based on the Esprima (Spidermonkey) format

npm install ast-module-types

API

Each of these takes in a single AST node argument and returns a boolean.

• isDefine: if node matches an AMD define function call (defining a module)
• isRequire: if node matches a require function all (declaring a dependency)
• isTopLevelRequire: if node matches a require at the very top of the file.
• isAMDDriverScriptRequire: if node matches an AMD driver script's require call require([deps], function)
• isExports: if the node matches CommonJS module.exports or exports (defining a module)

Detecting the various forms of defining an AMD module

• isNamedForm: if the node is a define call of the form: define('name', [deps], func)
• isDependencyForm: if the node is a define call of the form: define([deps], func)
• isFactoryForm: if the node is a define call of the form: define(func(require))
• isNoDependencyForm: if the node is a define call of the form: define({})
• isREMForm: if the node matches the form: define(function(require, exports, module){});

ES6 Types

• isES6Import: if the node is of the form: import 'mylib' or import {something} from 'mylib'
• isES6Export: if the node is of any es6 export form: ex: export default 123; or export { D as default };

Usage

var types = require('ast-module-types');

// Assume node is some node of an AST that you parsed using esprima or esprima-fb
// ...

console.log(types.isDefine(node));
