Determines if a file is using a CommonJS or AMD module definition

Package Exports

  • module-definition
  • module-definition/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (module-definition) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

module-definition

CI npm version npm downloads

Determines the module definition type (CommonJS, AMD, ES6, or none) for a given JavaScript file by walking through the AST.

npm install module-definition

Usage

const getModuleType = require('module-definition');

// Async
getModuleType('myscript.js', (error, type) => {
  console.log(type);
});

// Sync
let type = getModuleType.sync('myscript.js');
console.log(type);

// From source (string or an AST)
type = getModuleType.fromSource('define({foo: "foo"});');
console.log(type);

Passes one of the following strings to the given callback or returns the string in sync API:

  • amd
  • commonjs
  • es6
  • none

You may also pass an AST to fromSource to avoid an internal parsing of the source.

When specifying a filename, using the sync or async API, you can also provide an options object with an alternative fs implementation used to read the source file with.

const myFs = GetFs();
const options = { fileSystem: myFs };

// Async
getModuleType('myscript.js', (error, type) => {
  console.log(type);
}, options);

// Sync
const type = getModuleType.sync('myscript.js', options);

CLI

Assumes a global install module-definition with npm install -g module-definition
