React - Redux - Typescript - Firebase (example app)

Attendee project to add & remove attendees in event. This is a practice example of using React, Redux, Typescript and Firebase real-time database (read, write, remove).

Run project

1. Run yarn install
2. Run yarn start

Run with or without Firebase

By default, this app is working without Firebase, so enable connection, go to file ./helpers/helpers.tsx and set syncWidthFirebase = true;

Firebase setup

1. Create new Real-time database in https://console.firebase.google.com
2. Open your project
3. Project Overview > Project settings and copy & paste your credentials to .env.example
4. Rename .env.example to .env

Security rules

By default there are security rules in Firebase allowing full access to everyone. Google won't let you keep this forever.

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

In this project there is applied Anonymous authentication with following rules:

{
  "rules": {
    ".read": "auth.uid !== null",
    ".write": "auth.uid !== null"
  }
}

Data structure in Firebase real-time database

If you will have an empty database, data structure should be created while inserting first item. However you can create a data structure by importing a json file into a database.

{
    "attendees" : {
	    "1d39c26d-05f7-43f2-b4bb-301de32f2a85" : {
		    "color" : "#73457c",
	        "email" : "immortal@hero.com",
	        "id" : "1d39c26d-05f7-43f2-b4bb-301de32f2a85",
	        "name" : "Chuck Norris"
	    }
	}
}

At the end of a day, it's no difference, but you can later on convert anonymous users to authenticated users (if you decide later on to apply FB or Gmail or custom authentication).
