This is now an actual repo:
for app in $(heroku apps); do heroku apps:destroy --app $app --confirm $app; done |
Let's have some command-line fun with curl, [jq][1], and the [new GitHub Search API][2].

Array.prototype.myEach = function(callback) { | |
for (var i = 0; i < this.length; i++) | |
callback(this[i], i, this); | |
}; | |

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');
