The Absolute Beginners Guide to Reactive JavaFX on PragmaticCoding

Part 1 - A Quick Start

The very first step. What else? “Hello World” in JavaFX.

Part 2 - Configuring Layouts

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

Some basics about building layouts and making your screens look the way you want.

Part 3 - User Interaction

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

GUI applications need a way for the user to interact with them. In this lesson we’ll show how to allow user input with TextField, and to launch an action with a Button.

Part 4 - Styling

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

JavaFX includes Cascading Style Sheets for styling the elements of your GUI. This is a quick guide about how to use them.

Part 5 - Application Framework

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

Building an application that “does something” means adopting a framework that works well with JavaFX. Here we build the skeleton of the Model-View-Controller-Interactor framework that we’re going to use for our CRUD application.

Part 6A - First Feature: Minimal Create

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

The first feature for our CRUD application has to be “Create”. In this lesson we’ll get started by designing the GUI and connecting it to the Controller.

Part 6B - Adding Persistence

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

In this lesson we finish up a “bare-bones” Create function by building the back-end and connecting it to the business logic in the Interactor. Part of this involves creating a simulated database.

Part 7 - What Next?

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

Now we’ve completed the core programming for our “Create” function, where do go next. We’ll look at the idea of a “Product Backlog”, and talk about how we should prioritize our next steps.

Part 8 - Dealing With Latency and Blocking

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

Our simulated database doesn’t really do a good job standing in for a real database because it works too fast. We’ll slow it down and see what horrible things this does to our application. Then we’ll see how to deal with this.

Part 9 - GUI Validation

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

We’ve also got a big problem with our application because there’s no data validation in our screen. This means that users can save invalid customer data. We’ll look at how to cope with this properly.

Part 10 - Handling Database Errors

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

The last problem with our application is that it can save duplicate customer records, corrupting our database. This means adding some rules to our database and telling our GUI when those rules have been broken. We’ll see how to handle exceptions from the back-end in our application.

Part 11 - A "Working" Application

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

At this point we have a pretty clean “Create” application. It’s error resistant, doesn’t corrupt our database and ready to add some more functionality. Let’s look at what we’ve done so far.

Part 12 - Adding a New Field: eMail

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

It’s finally time to add a third field to our screen! In this article we’re going to add just a single new field, for email, to our screen. We’re going to see how the process goes from the View all the way down to the Broker. Most importantly, we going to see how we need to be vigilant in ensuring that our code stays clean as we add more features.

Part 13 - Feature Envy

nuno@n9o.xyz (Blowfish) — Mon, 01 Jan 0001 00:00:00 +0000

In this article we’re going to look at how Feature Envy has crept into our View code. We’re going to look at why this happens, and how to deal with it. Finally, we’re going to see how clearing out Feature Envy makes our code much cleaner and easier to understand.

So far we’ve built an application that does little, but demonstrates a lot. Now we’re going to write one of the most common types of application out there - CRUD (Create, Retrieve, Update and Delete).
