Learn Cloudflare, Faunadb and Ionic

Get started building web applications with Angular and Firebase.

In this course, you'll learn how to set up and use Firebase in your Angular applications using the AngularFire library.

We choose the AngularFire library because it is an official library created by the Firebase and Angular teams to work better with Angular.

It helps you by wrapping everything into observables and helps update zones. 

By the end of this course, you'll be able to build web applications using Cloud Firestore as your database, Firebase Authentication as your Auth system, Cloud Storage to save files, and Firebase Hosting to deploy your applications to the web.

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.

Build Full Stack Web Applications with Angular and Firebase


Next.js is one of the most popular server-side-rendered React frameworks you can use to build production-ready serverless applications in record time. 

On the other hand, Fauna is a flexible, serverless, distributed document-relational database. Fauna has a powerful GraphQL API and custom resolver support. 

Using Next.js and Fauna, you can build robust, feature-rich, production-ready full-stack applications without the hassle of managing any servers or databases.

In this course, Shadid guides you through building your very own full-stack serverless marketplace application using Next.js, GraphQL, and Fauna. 

You will learn,

- How to work with Apollo GraphQL Client in Next.js
- How to setup Fauna GraphQL
- Data modeling in Fauna
- How to write custom Fauna GraphQL Resolvers (UDFs)
- How to authenticate with Auth0?
- Stripe payment 



GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.

Full-Stack Serverless Applications with Next.js & Fauna

Cloudflare Workers let you write JavaScript Service Workers that run directly in Cloudflare's 200+ edge locations around the world.

With a Cloudflare Worker, you can modify your site's HTTP requests and responses, make parallel requests, and even reply directly from the edge.

Cloudflare Workers are written against a similar API to the W3C Service Workers standard. However, while Service Workers run inside the end user's browser, Cloudflare Workers run on Cloudflare's servers. This means that Cloudflare Workers can implement trusted code (which the client cannot tamper with), and will work no matter what browser the user is running.

In this course, Kristian Freeman will teach you how to build and deploy a Serverless API with Cloudflare Workers. By learning how to build your own serverless JSON APIs, you can effectively manage a highly-available backend for your projects, without needing to learn DevOps or manage services.

Cloudflare secures and ensures the reliability of your external-facing resources such as websites, APIs, and applications. It protects your internal resources such as behind-the-firewall applications, teams, and devices. And it is your platform for developing globally-scalable applications.

Build a Serverless API with Cloudflare Workers

Cloudflare Workers is a serverless application platform that enables you to create and deploy functions to Cloudflare's Edge Network.

Unlike other serverless providers that only have regional data centers, Cloudflare's Edge Network consists of hundreds of servers all over the world.

Cloudflare Workers is a powerful platform, and this course serves as a great introduction for what it can do.

Follow along with Kristian Freeman as you build a localization engine that renders data based on the Edge location nearest to the application's user.

After this course, you'll be ready to start experimenting with your own Cloudflare Workers projects. *Need an idea?* *[Check out the suggested Portfolio Project for this course.](https://egghead.io/projects/introduction-to-cloudflare-workers)*

Introduction to Cloudflare Workers

This application serves as an introduction to building products with a JAMStack and Serverless approach. We cover everything from the beginning:

* starting with the Gatsby client
* handling authentication with Netlify Identity
* Shipping a GraphQL server on Netlify Functions
* Building in access control with a serverless capable database

It uses tools that remove as many of the barriers as possible while also allowing upgrading in the future. Netlify Functions can grow into AWS Lambda, Netlify Identity can grow into Auth0 or Cognito, and FaunaDB can grow into DynamoDB.

Gatsby is a blazing fast static site generator built with React. Gatsby gives you all of the modern JavaScript tools you want; set up and ready to go out of the box.

Building a Serverless JAMStack Todo app with Netlify, Gatsby, GraphQL, and FaunaDB

This collection is a sequel to the [Building a Serverless JAMStack Todo app with Netlify, Gatsby, GraphQL, and FaunaDB](https://egghead.io/playlists/building-a-serverless-jamstack-todo-app-with-netlify-gatsby-graphql-and-faunadb-53bb) collection. In this collection we take the TODO application we built and convert it to run using Netlify Identity, AWS Lambda (using the serverless framework) and DynamoDB. We cover

* Fauna vs DynamoDB and when to use each
* Setting up AWS accounts
* Creating DynamoDB tables and data modeling differences between Fauna and Dynamo
* Converting our Netlify Functions deployment to a Serverless Framework deployment
* Implementing Custom authorizer functions on AWS

It uses tools that remove as many of the barriers as possible. Netlify Functions grows into Serverless Framework adn AWS Lambda, Netlify Identity is kept around, and FaunaDB can grows into DynamoDB.



FaunaDB is a global serverless database that gives you ubiquitous, low latency access to app data, without sacrificing data correctness. It eliminates layers of app code for manually handling data anomalies, security, and scale, creating a friendlier dev experience for you and better app experience for your users.

Converting a Serverless App to run on AWS Lambda and DynamoDB with Serverless Framework

The “Edge” is where you write and store your code where your data is being produced. This allows for a quick and efficient data transfer, eliminating or severely reducing lag. 

Supabase is a suite of open-source tools wrapping a PostgreSQL database. It provides the building blocks of an app - database hosting, auth, file storage, real-time, and edge functions - so we can focus on what makes our app unique.

Cloudflare Workers are serverless functions that run at the Edge! In this course, we will use the Wrangler CLI tool for interfacing with your Cloudflare account and creating or publishing your Workers.

KV Storage is a cache that Cloudflare makes available to our Workers. It replicates across multiple CDN nodes, making it super performant to cache data.

Combined, these three things give you the benefits of that reduced lag in a smooth and streamlined process. 

Throughout this course, Jon will teach you how to create a small blog that hits the key points of how to:

- Query Supabase from Cloudflare Workers
- Read and write KV Storage cache from Cloudflare Worker
- Cache Supabase response at the Edge with KV storage

And more!

Building native mobile applications has traditionally been a completely foreign work flow than web development. Recently frameworks, such as Ionic and React Native, have been come out to create a similar web development workflow in a native environment. 

Ionic 2 builds on top of Angular to offer a complete framework for building mobile apps using HTML, CSS, and Javascript that target native mobile and the browser. We’ll work with the RandomUser API to create an employee directory that will let us view user details, update that information, and pass the data back and forth with Ionic 2 routing.

Angular is a development platform for creating applications using modern web standards. Angular includes a wealth of essential features such as mobile gestures, animations, filtering, routing, data binding, security, internationalization, and beautiful UI components. It's extremely modular, lightweight, and easy to learn.

FaunaDB is a global serverless database that gives you ubiquitous, low latency access to app data, without sacrificing data correctness. It eliminates layers of app code for manually handling data anomalies, security, and scale, creating a friendlier dev experience for you and better app experience for your users.

Fauna is inspired by [Calvin](https://blog.acolyer.org/2019/03/29/calvin-fast-distributed-transactions-for-partitioned-database-systems/), has [built-in GraphQL integration](https://docs.fauna.com/fauna/current/api/graphql/), and a query language based on lambda calculus. Be sure to check out the [Jepsen analysis](https://jepsen.io/analyses/faunadb-2.5.4) and the associated [chart of consistency models](https://jepsen.io/consistency)

The Complete Guide to FaunaDB

The Edge is one of the most exciting new topics in web development. At the front of the pack is Cloudflare, whose network boasts servers located in hundreds of cities all over the world instead of in regions like "East" or "West".

More servers in more locations mean a faster experience for your users.

But what about the data part of the equation?

If the application you're working on skews more toward "reading" rather than "writing" data, Cloudflare Workers KV is a perfect fit.

Once you create a KV namespace— the "KV" stands for "key-value"— Cloudflare keeps track of your application data. The most commonly accessed data will be propagated around the world to the various Edge servers, while less popular data will be stored in more central locations.

Kristian Freeman has produced courses that introduce how to build and deploy sites and JSON APIs powered by Cloudflare Workers.

Today, he will show you how Workers KV can be integrated into a Cloudflare Workers project through building a Todo App.

## The Project

![todo-app-screenshot](https://res.cloudinary.com/dg3gyk0gu/image/upload/v1639014074/course-resources/Build-data-driven-applications-on-the-edge-with-Workers-and-Workers-KV/CleanShot_2021-12-08_at_16.46.39_2x.png)

Before you groan about a bland Todo App, think about it this way: 

The Todo App is the perfect example of the CRUD operations. Cloudflare KV has its own nuances for reading and writing data through a concept called Binding that is easier to grok when you understand the larger example as a whole.

As the course progresses, Kristian shares examples of how you can store more complex key-values, along with data operations like editing and filtering.

One of the coolest features that Cloudflare KV allows for is user-specific data that is tied to the IP address the request originates from. In other words, you'll be able to share your deployed Todo app with anyone around the world, and they will only see their personal items.

## **Gain these Skills**

- Manipulating data using Cloudflare Workers KV
- Make data unique to each user without logging in
- Effectively store lightweight data in Cloudflare Workers KV
- Setting up a key-value store and connected projects
- Reading and writing to a serverless key-value store
- Storing complex values in a Cloudflare KV store

## **Prerequisites**

You'll need to have a basic understanding of what Cloudflare Workers is recommended but not necessary. This course is relatively beginner-friendly into the world of Workers KV that you can get by with no knowledge on Cloudflare Workers. 

But if you want to get the most out of this course, we would recommend taking [Introduction to Cloudflare Workers](https://egghead.io/courses/introduction-to-cloudflare-workers-5aa3) to get a better understanding of how Workers KV comes into play.

Build Data-Driven Applications on the Edge with Workers and Workers KV

Gesture driven lists are a great way to take a simple UI element and make it fun. We'll look at how we can make swipe-able list items to reveal additional functionality, as well as being able to drag and reorder list items.

Use Sliding Gestures to Reorder an Ionic 2 List

In this lesson we will walk through how to break out code into it's own provider using the CLI. Ionic’s CLI provides a generate command that will quickly help create common components, pipes, providers, and much more. To see what kind of generators are available, run `ionic g --list` in your terminal. 

Use the Ionic CLI to Generate Angular 2 Mobile Components

The simplest way to display data in an app is with a simple listview. This list will go over how items work and how to place certain elements in ion-items position slots.

Build your first page component with Ionic 2

Ionic offers a few different layouts, including a side menu-based one. We’ll setup a simple side menu layout from scratch and see how it behaves on different devices. For instance, if you're users are on an Android device, the side menu (and really, the whole app) will look and behave like a native Android app. As the user swipes from the side, the menu will overlay the main content. For iOS, the menu will not move, but the app's main content will instead.

Ionic’s NavController offers an extensive API that allows you to manipulate your apps history, create history from nothing, and programmatically navigate back. NavController has an extensive API with many methods and lifecycle hooks that developers can use. Be sure to check out the [documentation](http://ionicframework.com/docs/api/navigation/NavController/)

Use Ionic 2 NavController to Manipulate App History

A common UI pattern in mobile apps is to be able to “pull” down on a list and fetch more data, or scroll and load more. This kind of pattern is built into Ionic with the ionRefresher component and ionInfiniteScroll component.


[Infinite Scroll](http://ionicframework.com/docs/2.3.0/api/components/infinite-scroll/InfiniteScroll/) and [Refresher](http://ionicframework.com/docs/2.3.0/api/components/refresher/Refresher/) can be heavily customized as well. Both components allow you to change what is shown as the user begins to perform their action. This allows for a much more customized experience!

Lazy Load Data with Ionic 2

Ionic 2 has it’s own navigation system that that makes it straightforward to link components. We’ll look at how to take data from one template and pass it to another using Ionic NavController. 

Instead of thinking in terms of URLs and hrefs, NavController allows devs to think in terms of a component stack. To navigate forward to a new view, a developer pushes a new component on to the navigation stack. To go back, the component is popped from the stack. This push/pop metaphor is borrowed from traditional native development and allows for a more flexible navigation paradigm.  

Navigate Between Mobile Screens  with the Ionic 2 NavController

Ionic’s CSS and JS can detect what platform a user is on, and adjust to make sure you’re getting the correct interface. To preview this locally, you can use the CLI’s `--lab` flag to see what your app will look like before it’s even deployed to a device.

Ionic provides a common API for displaying many overlay components, like Alerts, ActionSheet, Modals, and Popovers. We'll look at a few of the APIs and see how to interact with them. To learn more about these different APIs, be sure the view the documentation on them:

- [ModalController](http://ionicframework.com/docs/2.3.0/api/components/modal/ModalController/)
- [ViewController](http://ionicframework.com/docs/2.3.0/api/navigation/ViewController/)
- [AlertController](http://ionicframework.com/docs/2.3.0/api/components/alert/AlertController/)

Create an Overlay Component with the Ionic 2 Overlay API

Cards have become a common way to handle layout and display information in a easy-to-understand format. Ionic offers utility components that make creating cards straightforward. These components, like `ion-card`, `ion-card-content`, and `ion-card-header` are included in the framework to speed up the development process. There's no JavaScript behind these components, they're really just css driven. 

Create Angular 2 Mobile Card based layouts with Ionic 2

We’ll go over requirements needed to create a project and how to install the ionic CLI for project creation. Once it’s installed, we’ll start a project, specify an app name, and reuse a starter template for our project.
