+# `dlv(obj, keypath)` [![NPM](https://img.shields.io/npm/v/dlv.svg)](https://npmjs.com/package/dlv) [![Build](https://travis-ci.org/developit/dlv.svg?branch=master)](https://travis-ci.org/developit/dlv)
+
+> Safely get a dot-notated path within a nested object.
+
+### Why?
+
+Smallest possible implementation: only **120 bytes.**
+
+You could write this yourself, but then you'd have to write [tests].
+
+Implementation is ripped directly from [preact].
+
+Supports ES Modules, CommonJS and globals.
+
+### Installation
+
+`npm install --save dlv`
+
+
+### Usage
+
+```js
+import delve from 'dlv';
+
+let obj = {
+	a: {
+		b: {
+			c: 1
+		}
+	}
+};
+
+delve(obj, 'a.b.c') === 1;
+
+delve(obj, 'a.b') === obj.a.b;
+
+delve(obj, 'a.b.c.d') === undefined;
+```
