Udemy – Firebase In Depth 2022-10

Firebase In Depth course. If you are looking for the best backend to accompany your Angular frontend, the Firebase ecosystem (with Firestore NoSQL database) is the right choice for you. Today, developing Firebase apps is easier than ever thanks to the latest Firebase development tools, including the excellent local emulator (explained in detail in this course). Firebase allows us to build applications in a largely serverless way, meaning that we only need to write little, if any, server-side code when using it. With Firebase, we can not only query our database, but also perform data modification operations directly from the browser in a secure manner. So how is this possible? The way it works is that the Firestore database enables us to declaratively accept or reject incoming requests using Firestore security rules. A key element to this is Firebase authentication, which we’ll cover in detail in this course. Of course, Firebase is frontend agnostic, meaning it works with any frontend technology. So why does it work especially well with Angular? This is due to the powerful AngularFire library that allows us to easily query and modify Firestore data in a reactive manner using the AngularFire Observable based API. In addition to Firestore, the Firebase ecosystem provides everything else you need to build a fully functional backend solution. This includes secure file uploads via Firebase Storage and hosting of your static files via Firebase Hosting. For the rare cases where you need server-side code, you can do it in Firebase using Firebase Cloud Functions, which are node-based stateless functions that run on the Google Cloud infrastructure. With Cloud Functions, you can implement server-only functionality like database triggers or even REST endpoints for server-only operations like user creation or payments. The Firebase ecosystem provides a complete solution for rapidly building your web application backend, allowing you to focus more of your development time on the front end.

Course overview

In this course, we’ll take a sample Angular application and connect it to a Firestore database. We will learn how to perform a variety of database queries and provide a complete CRUD example using AngularFire. From the beginning we will set up a local development simulator that will allow us to use a local database with predefined authenticated users and some basic data. The simulator also allows us to test cloud functions locally as well as security rules, which is very convenient. From there, we want to add security to the application, starting with authentication using Firebase Authentication. We will implement email and password and social login using the Firebase UI library. We also plan to implement role-based authorization using custom Firebase Authentication claims and the AngularFire Authentication router guard. We will implement an admin page that allows an existing admin to create other users, including other admins, in a secure way. For this, we need backend code, so we’ll use Firebase Cloud Functions for that. We’ll also show how to use cloud functions to implement other common backend features, such as database triggers. We’ll show how to securely upload an image thumbnail using Firebase Storage. We’ll finish the course with a full production deployment using Firebase hosting and testing everything in a non-simulated production environment.

What will you learn in this course?

In this course, you’ll learn everything you need to know to become a skilled Firebase developer. You will learn how to model the Firestore database and how to interact with it using AngularFire. You’ll learn how to implement secure, transactional data modification queries directly using the AngularFire Observable-based API. You know how to secure your data using Firestore Security rules and how to implement role-based authorization. You’ll learn how to design your system to require minimal backend code, which can be implemented using Firebase Cloud Functions if necessary. By the end of the course, you’ll feel confident using the complete Firebase ecosystem to design and develop apps in a serverless way.
