12 | <br />
13 | 
14 | ## When should I use polyfill-io-feature-detection?
15 | + You want to isolate your app code from the browser supported features (applying polyfills)
16 | + You have to add polyfills to yout web application because requires support to different browsers and devices
17 | + You want to use polyfill service like [polyfill.io](https://polyfill.io/v2/docs) instead of including the polyfills in your bundle
18 | + You want (should) to [load polyfills only when needed](https://philipwalton.com/articles/loading-polyfills-only-when-needed)
19 | + You want to optimize the experience for users on modern browser
20 | + You want to save the polyfill service call when possible (using this polyfillLoader)
21 | 
22 | If you meet all these requirements, you probably will love this package. Because it allows you to load polyfills dynamically only when your browser really need it.
23 | 
24 | 
25 | ## Usage
26 | ```js
27 | function App () {
28 |     // your app code here
29 | }
30 | 
31 | import { polyfillLoader } from 'polyfill-io-feature-detection';
32 | polyfillLoader({
33 |   "features": "Promise",
34 |   "onCompleted": App
35 | });
36 | ```
37 | 
38 | ## Usage with React
39 | ```js
40 | // index.jsx
41 | import React from 'react';  
42 | import {render} from 'react-dom';  
43 | import App from './containers/App.jsx'; 
44 | 
45 | import { polyfillLoader } from 'polyfill-io-feature-detection';
46 | // This function load polyfills only if needed. By default it uses polyfill.io
47 | polyfillLoader({
48 |   "features": "Promise,fetch",
49 |   "onCompleted": main
50 | });
51 | 
52 | // That function will be called after loading polyfills
53 | function main() {
54 |   render(
55 |     <App />
56 |     , document.getElementById('starter')
57 |   );
58 | }
59 | ```
