Workbox runtime caching recipes

Your Service Worker script will need to import in Workbox and initialize it before calling any of the routes documented in this write-up, similar to the below:

importScripts('workbox-sw.prod.v1.3.0.js');
const workbox = new WorkboxSW();

// Placeholder array populated automatically by workboxBuild.injectManifest()

This describes the common mistake with using closures in JavaScript.

A function defines a new environment

Consider:

function makeCounter()
{
  var obj = {counter: 0};

Guide to CORS

CORS (cross origin resource sharing) is a mechanism to allow client web applications make HTTP requests to other domains. For example if you load a site from http://domainA.com and want to make a request (via xhr or img src, etc) to http://domainB.com without using CORS your web browser will try to protect you by blocking the response from the other server. This is because browsers restrict responses coming from other domains via the Same-Origin-Policy.

CORS allows the browser to use reponses from other domains. This is done by including a Access-Control headers in the server responses telling the browser that requests it is making is OK and safe to use the response.

Header	Description
`Access-Control-Allow-Origin:`	Allow requests from `` to access t
