Apex File Naming Standards

Consistent file naming helps keep Visualforce and Apex classes easy to recognize and find. I’ve seen many orgs with both the good and the bad. Below is a table with naming suggestions. Some of them are mine, but most came from a presentation that I found referenced in a Trailhead module. The presentation is by Vivek Chawla. I recommend looking it over because it covers a lot of good stuff. Thank you Vivek.

Apex and Visualforce Naming

  • UpperCamelCase
  • Avoid using underscores.
  • Use full names where possible. Be consistent.
  • Test class should be named for the class they cover, and the word “Test” should be appended to the end.
Functional Type Name Suffix Examples
Trigger Trigger AccountTrigger
Trigger Handler TriggerHandler AccountTriggerHandler
VF Controller Controller AccountCloneController
VF Controller Extension ControllerExt AccountCloneControllerExt
Service Class Services AccountServices
Utility Class Util AccountDupeCatcherUtil
Selector Class Selector AccountSelector
Model / Wrapper Class Varies… Accounts / AccountWrapper
Web Service (SOAP) Ws AccountToolsWs
Web Service (REST) Rest AccountToolsRest
Email Service EmlSvc AccountCreateEmlSvc
Asynchronous (Future) Async AccountIntegrationsAsync
Asynchronous (Batch) Batch AccountMigrationBatch
Scheduled Apex Job AccountCleanupJob
Queueable Apex Que AccountSyncingQue
Visualforce Page -none- AccountClone
Visualforce Component Cmp AccountCloneCmp
Lightning Components -TBD-
Lightning Pages -TBD-

Workflow Rule, Field Update, and Email Alert Naming

Workflow Rules and their actions can also get unruly without consistent naming. Force365 published some good suggestions. Below are the ones that I refer to most.

Workflow Rule
[Object]: [Criteria Description i.e. Condition]

Workflow Actions
Field Update –
Set [Field] to [Value]
Email Alert –
Send [Template short description]
Task –
[Task Subject]
