module-definition v6.0.0
module-definition
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
