Below is a compilation of the top 3 most important trigger best practices for Salesforce. Keep in mind that there are many but the insights below will highlight some of the key elements that must be put in place to attain ultimate success in this regard.
Salesforce trigger best practices #1: Allocate one for just one object
To get us started on these Salesforce tutorials on trigger best practices it is critical to adhere to this principle. A single apex trigger is definitely all you will ever need for one distinct object. If you decide to create multiple triggers for just one object, you will lose control over the exact precedence they are fired. A single trigger is in a position of handling all the possible context combination of apex trigger. These are before insert, before `update, after insert, after update , after delete and after undelete. One of the best Salesforce trigger best practices is to always create a single trigger for each object. Then let it work will with all possible contexts you wish to create.
Salesforce trigger best practices #2: Create logic-less triggers
This example takes us directly to one of the most fundamental Salesforce basics you need to understand. Making a trigger logic-less simply means that you create a handler class that you can then delegate the necessary logic tasks you wish to execute. There is a wide variety of mitigating reasons why you should do so. To begin with, testing a trigger is next to impossible when the logic is situated in directly in it. On the other hand, if you create subroutines in your trigger they cannot be exposed to testing reasons. Thirdly, you cannot expose logic to be reused anywhere else in your organization. Packing all logic tasks directly in your triggers will backfire on you sooner or later. To avoid this you should create a handler class and let it deal with all the logic tasks you wish to implement in your trigger.
Salesforce trigger best practices # 3: Code context specific handler subroutines
This happens to be one of the most prevalent executed Salesforce trigger best practices that you ought to also implement into your trigger coding. If you wish to add a new logic, for instance, one that should run on after update, you will quite simply add a new handler subroutine to the trigger. Doing this will go a long way in enabling you to just add some simplistic routing logic into the apex trigger. This will make sure that the appropriate handler method can be called at the right time you wish it to do so. Hope this Salesforce training material has been insightful.
There are many other Salesforce trigger best practices. However, the three practices mentioned above are the most important. Implementing them will ensure that your system is not overwhelmed; and that the organization functions optimally as it should.
