IndexedDB CRUD
//https://habr.com/post/213515/
// This works on all devices/browsers, and uses IndexedDBShim as a final fallback
var indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.msIndexedDB || window.shimIndexedDB,
IDBTransaction = window.IDBTransaction || window.webkitIDBTransaction || window.msIDBTransaction,

function logerr(err){
console.log(err);

# 30 minutes Lisp in Ruby

#
# This Lisp implementation does not provide a s-expression reader.
# Instead, it uses Ruby syntax like following code:
#
# [:def, :factorial,
# [:lambda, [:n],
# [:if, [:"=", :n, 1],
# 1,

Very Simple IndexedDB Example
// This works on all devices/browsers, and uses IndexedDBShim as a final fallback
var indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.msIndexedDB || window.shimIndexedDB;
// Open (or create) the database
var open = indexedDB.open("MyDatabase", 1);
// Create the schema
open.onupgradeneeded = function() {
var db = open.result;
var store = db.createObjectStore("MyObjectStore", {keyPath: "id"});

Inspired by @JEG2's talk at Rubyconf... Any ruby object, as a webapp! 'Cause we can. :-)
require 'rubygems'
require 'rack'
class Object
def webapp
class << self
define_method :call do |env|
func, *attrs = env['PATH_INFO'].split('/').reject(&:empty?)
[200, {}, send(func, *attrs)]
end

Simple indexedDB example that will work both in Chrome and FF

// until we won't need this prefix mess
var indexedDB = window.indexedDB || window.webkitIndexedDB
|| window.mozIndexedDB || window.msIndexedDB;
var IDBTransaction = window.IDBTransaction ||
window.webkitIDBTransaction;

Working example of an IndexedDB implementation to handle transactions surrounding a fake invoice database
const request = window.indexedDB.open("database", 1);
// Create schema
request.onupgradeneeded = event => {
const db = event.target.result;
const invoiceStore = db.createObjectStore("invoices", { keyPath: "invoiceId" });
invoiceStore.createIndex("VendorIndex", "vendor");
const itemStore = db.createObjectStore("invoice-items", { keyPath: ["invoiceId", "row"] });
