What are the Apex Best Practices in 2023?

Salesforce is one of the most well-known and effective cloud-based CRM systems. To obtain additional workflow or configuration, you may need to change the development in specific use scenarios. Salesforce's default configurations allow the majority of clients to utilize it exactly as it is. Consider creating your own mobile or online application and wanting to integrate Salesforce into it. One of the essential requirements for doing this is obtaining data from Salesforce on each update to a Salesforce record. However, how can you get Salesforce to send you data anytime something changes? Apex Trigger is a helpful tool to achieve this.  

Salesforce offers Apex, a multitenant language when you need to create backend code for your own special business application. Apex Code, which may be written in both triggers and classes, can be started by triggers on the objects or by web service requests. 

There are some rules and recommended practices that backend developers in Salesforce should adhere to when writing Apex code. To make your system scalable and maintainable, you should heed these suggestions.

Bulkify Apex Code

Here, bulkifying refers to the handling of several records at once. Our code won't run if we receive more than one record, thus we constantly plan for the possibility of nullification. This is an illustration of bulkification. 

Make code Reuseable by

According to what we can infer from that line. Making auxiliary classes and adding methods to them is a constant requirement. We can call that class and use that method if we require the capability of that method. That is how we achieve code reuse. 

Avoid Nesting Loops within Loops 

In Apex controllers, 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. 

When there are two, three, or more performance-affecting barriers formed, we typically run into code. Using Maps is a simple technique to prevent nesting traps. For each second loop item, for instance, you may locate or make a key, then enter a key and value on the map. 

Avoid DML & SOQL Inside for Loops 

As we are aware, the governor limit notion establishes a precise restriction for our DML activity. You can conduct a DML procedure 150 times, for example, limit 150. Our code will be broken if the loop is executed more than 150 times.

Apply Database Techniques for Doing DML operations

DML and Database Methods basically operate in the same ways. But the key distinction is that database approaches are more adaptable than DML. 

  1. DML operation lacks a term. But the database approaches only operate partially.
  2. The list of successful and unsuccessful records cannot be retrieved in DML. However, using database methods, we can obtain the same.

Query Large Data Sets 

A SOQL in the salesforce ecosystem has a record-high return rate of 50,000 results. We should always use SOQL queries if we are working with huge data sets. 

Here is an illustration of how to utilize a Soql query for big data collections.
