Salesforce Apex is an object-oriented, strongly typed programming language that allows developers to execute flow and transaction control statements on Salesforce servers in conjunction with calls to the API.
Salesforce is considered the #1 CRM system across the world. The platform offers Apex, a multitenant language when users need to create backend code for their business application. Apex Code may be written in both triggers and classes and can be started by triggers on the objects or by web service requests.
In this blog, CloudVandana will discuss the five best practices of Salesforce Apex.
Salesforce Apex Best Practices
1. Apex Code Bulkification
Code Bulkifying refers to handling various records at a time. In triggers, up to 200 records can run at a time. If developers fail to write the codes to take that into account, an unexpected error can occur. Developers can Bulkify code to improve the performance of a piece of code, where the number of queries or other operations can be reduced.
2. Code Modularization
While writing code, there are chances that sections and pieces of the code are repeated throughout the codebase. This may create an unmanageable mess code, and each time it introduces a greater risk of further bugs.
3. Use SOQL For Loops
Governor limits within salesforce Apex are the heap size limit which is a runtime limit on the memory our code consumes dynamically as it runs, and when the limit exceeds, the governor system terminates the transaction. Instead of assigning the query result to a variable, users can place the query directly. It causes some changes to how the query is performed, preventing us from running into heap limits the users may have encountered before.
4. Avoid Nested Loops
Nested loops should be avoided as they may impede page execution or may exceed the page’s imposed constraints. Making the inner loop serve a different purpose or eliminating the use of loops entirely is another simple method that provides a good structure. Using Maps is a simple technique to prevent nesting traps.
5. Test Multiple Scenarios
Salesforce limits 75% code coverage while deploying Apex code into production. Writing tests lead to code coverage requirement and shows the code has been run and does not provide any value other than showing that. When writing tests, developers should not worry much about code coverage and instead concern themselves with different use cases for the codes.
