node-resolve

Locate modules using the Node resolution algorithm, for using third party modules in node_modules.

v1.3.x breaking change, you have to pass a 'cwd' to resolve, '.' is default.

var nodeResolve = require('node-resolve');

nodeResolve.resolve('src/index.js', './foo/foo', '.');// src/foo/foo.js
nodeResolve.resolve('src/index.js', 'babel-core', '.');// node_modules/babel-core/index.js

undefined is returned if not found, and null is returned if it's a builtin module(fs,path...).

node-resolve supports browser spec.

nodeResolve.resolve('src/index.js', 'inherits', '.', true)// inherits_browser.js
nodeResolve.resolve('src/index.js', 'fs', '.', true)// undefiend
