Realtime Database triggers with Cloud Functions for Firebase - source

This gist contains the source code in my video series about Realtime Database triggers. You can watch the three parts here:

1. Part 1 (intro, onCreate)
2. Part 2 (onUpdate, infinite loops)
3. Part 3 (onDelete, transactions)

index.ts contains the Cloud Functions code, and dialog.ts contains the script to run

Creating a Shopping List API

In this lesson you will be using your Node.js and Express skills to create the back end for a simple Shopping List application. The application will allow users to add, read, update and remove shopping items. You'll learn about the CRUD model and RESTful APIs, then put this into practice when creating the back end.

Goals

• Understand the basics of CRUD and REST
• Create RESTful endpoints which perform all of the CRUD operations

Reveal Module Pattern

A reveal module is an immediately-invoked function expression that returns an object who's methods have closure over the enclosing functions variable scope.

Breaking down the definition, there are 3 key aspects to reveal-module.

1. The outer function is executed using a the IIFE syntax (...)();. This has the benefit of preventing any polution of the global scope with extra unnecessary varaibles.

2. The outer function returns an object literal with functions as properties (methods). This is a factory that generates an object with methods (functions) and properties (variables).

3. Those methods create a closure over the scope so the retain (read, remember) the scope where they were defined. This effectively creates private properties and methods.

Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.

Setup
