+# os-tmpdir [![Build Status](https://travis-ci.org/sindresorhus/os-tmpdir.svg?branch=master)](https://travis-ci.org/sindresorhus/os-tmpdir)
+
+> Node.js [`os.tmpdir()`](https://nodejs.org/api/os.html#os_os_tmpdir) [ponyfill](https://ponyfill.com)
+
+Use this instead of `require('os').tmpdir()` to get a consistent behavior on different Node.js versions (even 0.8).
+
+
+## Install
+
+```
+$ npm install --save os-tmpdir
+```
+
+
+## Usage
+
+```js
+const osTmpdir = require('os-tmpdir');
+
+osTmpdir();
+//=> '/var/folders/m3/5574nnhn0yj488ccryqr7tc80000gn/T'
+```
+
+
+## API
+
+See the [`os.tmpdir()` docs](https://nodejs.org/api/os.html#os_os_tmpdir).
