Learn Docker, Flexbox 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

It's tempting to pick up a framework which has preselected flexbox or grid as the layout tool of choice, but it's important to learn when and why to use each method. This leads to slimmer stylesheets which results in better site performance, and less likelihood for "hacks" to make one method do what the other does inherently better. 

Throughout this collection, we will be progressively styling a responsive landing page template while building your knowledge on when to select grid or flexbox for any layout scenario. Spoiler alert: sometimes the best solution is using both!

The specification describes a CSS box model optimized for user interface design. In the flex layout model, the children of a flex container can be laid out in any direction, and can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent.

Create a Landing Page with CSS Grid and Flexbox

While "It works on my computer" might give you an excuse to close a bug ticket in the backlog, it doesn't really work when you're working on a team.

You need to ensure that your application can run regardless of what hardware your teammates are running or libraries they have installed.

Docker solves this problem by collecting everything your application needs to run into a container.

Containers aren't just for source code. They can hold configuration, scripts, and even their own filesystem. It's similar to a Virtual Machine, without having to bring a full operating system along for the ride.

Because containers run in isolation, there is some configuration involved to allow for files to be saved and containers to communicate with one another.

One of the most useful ways to get your head around Docker is to see it in action.

Follow along with Joel Lord as he works through the process of preparing an application to run in separate containers for the frontend and backend of an application that searches for gifs and re-encodes them with a caption supplied by the user.

You'll see how to configure the separate containers to communicate with one another, work with environment variables, and persist data to your local machine. Along the way, you'll pick up some tips on useful commands and bash scripting. Finally, you'll learn how to use Docker Compose to make it easy to run multiple containers simultaneously.


Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries – anything that can be installed on a server. This guarantees that the software will always run the same, regardless of its environment.

Containerize Full-Stack JavaScript Applications with Docker

Docker Fundamentals

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.

Building apps with Ionic 2

In this course we will take a simple Node.js app that connects to a MongoDB database and uses an Express web server, and learn how to setup a full software development deployment process as well as how to properly “Dockerize” the app. 

We’ll step through setting up proper version control techniques, managing configuring within the environment, setting up proper build/deploy/run processes, and all with abiding by Docker best practices. We’ll also make sure our deployment is setup for scale, and have consistent development practices in place for reliable app deployments.

Flexbox is a powerful way to layout HTML so that elements can grow to fit the size of their container.  It can also control how the elements are positioned within a flexed container.  

Once you start thinking in `rows` and `columns`, you can control almost any flexed layout with just a few simple flexbox layout primitives.

Get Started with Flexbox CSS Layouts

Flexbox is a wonderful tool built into the CSS specification. Using flexbox doesn't require any special framework or library, just a browser with CSS3 support. It is so awesome, and makes the arranging elements on a page almost fun!

Flexbox Fundamentals

Demystifying alignment in flexbox children

Flexbox makes it easier to create layouts that can adjust depending on the content that is added and the space available. In this lesson we look at a couple real-world applications of Flexbox in an application and website.

Using Flexbox in Websites and Applications

The flex-basis property allows us to define the dimension (along the flex-direction axis) that a flexbox child should ideally have.

Defining dimensions on flexbox children using flex-basis

Docker containers are stateless by default. In order to persist filesystem changes, you must use docker volumes. In this lesson, we will go over how to copy files over to Docker containers, how to create volumes and copy data to them, and also how to mount remote folders for persisting updates.

Create Docker Volumes for Persistent Storage

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/)

In this lesson we will cover proper version tagging when building Docker images, creating a docker-compose.yml file for proper release management, and running the tagged release by using Docker Compose to launch app resources as Docker containers.

Build, Release and Run Containers with Docker Compose

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

Flex-basis lets us set the ideal dimensions for a flexbox child, but flex-shrink lets us define what should happen if there isn't enough room, and flex-grow can define what happens when there is too much room.

Using flex-shrink and flex-grow to make flexbox children resize correctly

Using the `order` property we alter the order in which flexbox children appear on the page, without making changes to the dom.
