Rapid Application Development with OutSystems

By: Ricardo Pereira

Overview of this book

OutSystems is a software development platform that speeds up the build phase by abstracting code and making almost everything visual. This means replacing textual language with visual artifacts that avoid lexical errors and speed up code composition using accelerators and predefined templates. The book begins by walking you through the fundamentals of the technology, along with a general overview of end-to-end web and mobile software development. You'll learn how to configure your personal area in the cloud and use the OutSystems IDE to connect with it. The book then shows you how to build a web application based on the best architectural and developmental practices in the market, and takes the same approach for the mobile paradigm. As you advance, you'll find out how to develop the same application, and the great potential of reusing code from one paradigm in another and the symbiosis between them is showcased.The only application that'll differ from the application in the exercise is the one used in business process technology (BPT), with a focus on a common market use case. By the end of this OutSystems book, you'll be able to develop enterprise-level applications on the web and mobile, integrating them with third parties and other systems on the market. You'll also understand the concepts of performance, security, and software construction and be able to apply them effectively.

Chapter 10: Client-Side Logic

For our frontend to work smoothly, efficiently, and with all the necessary capabilities, it's just not enough for us to have a good backend and very well-designed screens.

There is a very powerful feature in frontend development that gives us the ability to work our features down to the smallest detail: Client Actions!

These actions are implemented in a very similar way to server actions but must always be developed considering that they occur on the client side—that is, in the browser. In short, they're implemented in the same way, but the approach is slightly different.

Client Actions can exist at a screen level and a module level.

In this chapter, we will focus on client-side logic and explore the following topics:

  • Screen actions
  • Data actions
  • Client logic actions
  • Exercise 6 – creating Client Actions and using them on the frontend

By the end of this chapter, we should be able to implement...
