Clean code in Salesforce

In this session, we discuss how to take quickly written code and apply best practices to refactor it. Join us to learn how to write Clean Apex Code in Salesforce. We will take a messy piece of code step by step and refactor it.

Why do we need Clean code in Salesforce?

Why do we need clean code? Destructive code works, too! Don’t fix what is not broken. Let’s understand why we need it in Salesforce.

Best practices to write clean code in Salesforce

Follow the best practices below to write good code in Salesforce.

• Easy to understand by other developers: readable by developers other than the one who developed it.
• Easy to maintain: lower chances of accidentally introducing bugs.
• Modified without fear of breaking anything: Many Salesforce developers take great pride in making the code compact – trying to do multiple things on one line – which might be impressive but makes the code much harder to read and understand.

Rules to write Clean Code

• Keep your methods short.
• Don’t repeat yourself.
• Methods should do just one thing.
• Clear, intention-revealing names.
• Comment to clarify, not explain.
• Leave everything better than you found it.
