    module-graph

    Build Status Dependency Status NPM version

    Utility for obtaining the dependency graph from ES6 modules.

    Limitations

    module-graph only works for source code that the Esprima parser can parse. This does not include the whole ES6 syntax at the moment. Consider this module experimental.

    API

    graph(source, [options])

    module-graph exports a single function that takes a string with source code and returns an array of the dependencies in that module:

    var graph = require('module-graph');
     
    var result = graph('import foo from "bar"; export default foo;');
    // returns an array like ['bar']

    If the includeBindings option is set to true, then the graph function will return an object containing all the imported and exported names of the module:

    var graph = require('module-graph');
     
    var result = graph('import foo from "bar"; export default foo;', {
        includeBindings: true
    });
    /* result looks like this:
    {
        imports: {
            'foo': ['bar']
        },
        exports: ['default']
    }
    */

    Optionally, if you're already dealing with an AST that contains ES6 imports or exports, you can pass that AST object to the graph function:

    var esprima = require('esprima'); // Make sure your Esprima version supports ES6!
    var graph   = require('module-graph');
    
    var ast = esprima.parse('import foo from "bar"; export default foo;');
    var result = graph(ast);
    

    Note: none of the dependency names are normalized. It's up to you to decide how to normalize them.

    CLI

    If installed with npm install module-graph -g it can be used as a global command module-graph paths... [options] which will generate a JSON file with all the dependency information. Try module-graph --help for more information.
