Resolve Procore CDN

Motivation

Browsers only allow 6 current requests to the same domain. In order to overcome this restriction procore has 4
subdomains for fastly. This helper function will alternate between the subdomains in a sequence of 0-3 by default. The results are memoized, the same string will result with the same value.

Usage

``javascript
cdn(numberOfDomains: number) {
return cached(bgImg: string)
return string
}
`

Example

`javascript
import _cdn from '@procore/cdn';
import testImg from './test.png';
import bgImg from './bg.jpg';

const cdn = _cdn(4)

const App = () => {
return (


/*
https://procore-production-assets0.global.ssl.fastly.net/22028741.png
*/

url(${cdn(bgImg)})} />
