storage-available
#### Detect if web storage is available and functional


.
This microscopically small module contains only a single function,
storageAvailable, that detects whether the Web Storage API methods are available. The reason you would want to use a separate module for feature detecting Web Storage is because it is
hard and error prone.
This function is the one
recommended by the MDN documentation on Web Storage. I can claim copyright (and share it with you under the MIT license) because I
contributed that part of the docs.
Install
``
sh
npm install --save storage-available
`
Require
`
js
var storageAvailable = require('storage-available')
`
Import
`
js
import storageAvailable from 'storage-available'
`
Usage
`
js
if (storageAvailable('localStorage')) {
// Yippee! We can use localStorage awesomeness
}
else {
// Too bad, no localStorage for us
}
`
You can test for sessionStorage instead by calling storageAvailable('sessionStorage')`.
>
NOTE: This module is intended for use in the browser, or other environments that natively support Web Storage. Use it via a web bundler such as Browserify or Webpack.
