This chapter focused on how you can package your Lightning Components and other assets, and the steps required to publish on Salesforce AppExchange. This also brings us to the end of this book. This book covers the basics, so you can start building your Lightning Components using Salesforce DX and Lightning design systems to solve your business needs with custom Lightning Components. This book also extensively covered Salesforce DX and how it can accelerate development on the Salesforce platform. Lightning Component, along with Salesforce DX, is the future of Salesforce application development. If you are building enterprise applications, I would also recommend you build some design patterns around the framework or use open source projects, such as LAX (https://github.com/ruslan-kurchenko/sfdc-lax). In the coming years, it will be interesting to see how Salesforce further improves the component framework, as JavaScript and web components evolve, and the capabilities that it adds to the Salesforce DX and its packaging ability. Keep an eye on the Salesforce release notes with every release to find enhancements and improvements. Salesforce also offers Trailhead as a learning tool. I strongly recommend readers leverage trailhead.Salesforce.com to get hands-on experience with projects and modules for free on Trailhead.
