Book description

Build, design, and style beautiful and informative applications on the Salesforce Lightning platform

Key Features

  • Build and Test Lightning Components that enhance application usability and adaptability
  • Apply Security Best Practices to your Custom Lightning Components
  • Design Lightning Components for Salesforce UIs such as Lightning Pages, Salesforce 1 Application, Communities, and more.

Book Description

Built on the Salesforce App Cloud, the new Salesforce Lightning Experience combines three major components: Lightning Design System, Lightning App Builder, and Lightning Components, to provide an enhanced user experience. This book will enable you to quickly create modern, enterprise apps with Lightning Component Framework.

You will start by building simple Lightning Components and understanding the Lightning Components architecture. The chapters cover the basics of Lightning Component Framework semantics and syntax, the security features provided by Locker Service, and use of third-party libraries inside Lightning Components. The later chapters focus on debugging, performance tuning, testing using Lightning Testing Services, and how to publish Lightning Components on Salesforce AppExchange.

What you will learn

  • Understand Lightning Components architecture
  • Learn Locker security best practices
  • Debug and Improve performance of your Lightning Components
  • Use third-party libraries along with Lightning Component Framework
  • Learn how to publish Lightning Components on AppExchange
  • Use Lightning Out to take your Lightning Components outside the Salesforce platform

Who this book is for

This book is for Salesforce developers or developers from other platforms who are familiar with HTML, CSS, and JavaScript and want to build and test Salesforce Lightning components. No knowledge of Salesforce Lightning is required.
