This Course in a Nutshell
If you are looking for the best backend to go along with your Angular frontend, then the Firebase ecosystem (with the Firestore NoSQL database) is the right choice for you.
Today, it’s simpler than ever to develop Firebase applications thanks to the latest Firebase development tools, including the awesome local emulator (covered in detail in the course).
Firebase allows us to build applications in a mostly serverless way, in the sense that when using it we only have to write a little bit of server-side code, if any at all in a lot of cases.
With Firebase, we can not only query our database but also do data modification operations straight from the browser, in a secure way. So how is this possible?
The way that this works is that the Firestore database enables us to declaratively accept or deny incoming requests using Firestore Security Rules.
A key ingredient for this to work is Firebase Authentication, which we will cover in detail in this course. Firebase is, of course, frontend agnostic, meaning that it will work with any frontend technology. So why does it work especially well with Angular?
This is due to the powerful AngularFire library, which allows us to easily query and modify Firestore data in a reactive way using the AngularFire Observable-based API.
Besides Firestore, the Firebase ecosystem provides everything else that you need for building a fully functioning backend solution. This includes secure file upload via Firebase Storage and the hosting of your static files via Firebase Hosting.
For the rare cases when you need some server-side code, you can do that too in Firebase using Firebase Cloud Functions, which are node-based stateless functions running on the Google Cloud infrastructure.
Using Cloud Functions, you can implement server-only functionality like database triggers, or even REST endpoints for operations that can only be done on the server, such as user creation, or payments.
The Firebase ecosystem provides a complete solution for quickly building the backend of your web application, allowing you to focus more of your development time on the frontend.
Course Overview
In this course, we are going to take a sample Angular application and we are going to connect it to a Firestore database. We will learn how to do all sorts of database queries and we will provide a complete CRUD example using AngularFire.
We will set up the local development emulator from the very beginning, which will allow us to use a local database with predefined authentication users and some initial data.
The emulator will also allow us to test cloud functions locally as well as security rules, which is super convenient.
From there, we are going to add security to the application, starting with authentication using Firebase Authentication. We will implement both email and password and social login using the Firebase UI library.
We are also going to implement role-based authorization using Firebase Authentication custom claims and the AngularFire Authentication router guard.
We will implement an administration screen that allows an existing administrator to create other users, including other administrators in a secure way.
For this, we will need some backend code, so we will be using Firebase Cloud Functions for that. We will also show how to use Cloud Functions to implement other commonly used backend features, such as database triggers.
We will show how to do secure file upload of an image thumbnail using Firebase Storage.
We will end the course by doing a full production deployment using Firebase Hosting, and testing everything out in a non-emulated production environment.
