Build Applications Programmatically on the Salesforce Platform - DEX-450

This course is designed for developers looking to write pro-code customizations for business logic and user interface (UI) layers using Apex, Visualforce, and Lightning Web Components. Students will ideally have a solid understanding of core object-oriented programming concepts and experience building no-code solutions on the Salesforce Platform, although this is not required. This is also a great class for developers looking to earn their Salesforce Platform Developer I credential. 

 

IMPORTANT: Students are expected to follow the steps detailed in the Computer Set-up Guide for this class if you’ll be using your own computer when attending a virtual or in-person class.

• Design custom pro-code solutions that effectively leverage no-code customizations.
• Write basic Lightning Web Components and basic Visualforce markup and code to customize the UI. 
• Use Apex triggers and classes to write business logic customizations that use Salesforce Object Query Language (SOQL), Salesforce Object Search Language (SOSL), and Data Manipulation Language (DML).
• Test Apex by using the built-in testing framework.
• Explain how trigger code works in accordance with the Salesforce Order of Execution.
• Understand key fundamentals of designing programs on a multi-tenant platform.
• Use Visual Studio Code, the Salesforce Extension Pack, and Salesforce Command Line Interface (CLI) to learn about modern toold for developing on the Salesforce platform.
