+# resolve
+
+implements the [node `require.resolve()`
+algorithm](http://nodejs.org/docs/v0.4.8/api/all.html#all_Together...)
+such that you can `require.resolve()` on behalf of a file asynchronously and
+synchronously
+
+[![build status](https://secure.travis-ci.org/substack/node-resolve.png)](http://travis-ci.org/substack/node-resolve)
+
+# example
+
+asynchronously resolve:
+
+``` js
+var resolve = require('resolve');
+resolve('tap', { basedir: __dirname }, function (err, res) {
+ if (err) console.error(err)
+ else console.log(res)
+});
+```
+
+```
+$ node example/async.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+synchronously resolve:
+
+``` js
+var resolve = require('resolve');
+var res = resolve.sync('tap', { basedir: __dirname });
+console.log(res);
+```
+
+```
+$ node example/sync.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+# methods
+
+``` js
+var resolve = require('resolve')
+```
+
+## resolve(id, opts={}, cb)
+
+Asynchronously resolve the module path string `id` into `cb(err, res [, pkg])`, where `pkg` (if defined) is the data from `package.json`.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* opts.package - `package.json` data applicable to the module being loaded
+
+* opts.extensions - array of file extensions to search in order
+
+* opts.readFile - how to read files asynchronously
+
+* opts.isFile - function to asynchronously test whether a file exists
+
+* opts.packageFilter - transform the parsed package.json contents before looking
+at the "main" field
+
+* opts.pathFilter(pkg, path, relativePath) - transform a path within a package
+ * pkg - package data
+ * path - the path being resolved
+ * relativePath - the path relative from the package.json location
+ * returns - a relative path that will be joined from the package.json location
+
+* opts.paths - require.paths array to use if nothing is found on the normal
+node_modules recursive walk (probably don't use this)
+
+* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`
+
+default `opts` values:
+
+``` javascript
+{
+ paths: [],
+ basedir: __dirname,
+ extensions: [ '.js' ],
+ readFile: fs.readFile,
+ isFile: function (file, cb) {
+ fs.stat(file, function (err, stat) {
+ if (err && err.code === 'ENOENT') cb(null, false)
+ else if (err) cb(err)
+ else cb(null, stat.isFile())
+ });
+ },
+ moduleDirectory: 'node_modules'
+}
+```
+
+## resolve.sync(id, opts)
+
+Synchronously resolve the module path string `id`, returning the result and
+throwing an error when `id` can't be resolved.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* opts.extensions - array of file extensions to search in order
+
+* opts.readFile - how to read files synchronously
+
+* opts.isFile - function to synchronously test whether a file exists
+
+* `opts.packageFilter(pkg, pkgfile)` - transform the parsed package.json
+* contents before looking at the "main" field
+
+* opts.paths - require.paths array to use if nothing is found on the normal
+node_modules recursive walk (probably don't use this)
+
+* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`
+
+default `opts` values:
+
+``` javascript
+{
+ paths: [],
+ basedir: __dirname,
+ extensions: [ '.js' ],
+ readFileSync: fs.readFileSync,
+ isFile: function (file) {
+ try { return fs.statSync(file).isFile() }
+ catch (e) { return false }
+ },
+ moduleDirectory: 'node_modules'
+}
+````
+
+## resolve.isCore(pkg)
+
+Return whether a package is in core.
