Install the Sample Database Application – go into its Shared Components -> Plugins, and look at each of the plugins therein.The two sources I would recommend you look at are: In my opinion, a great way to get started learning about plugins is to examine a lot of plugins that others have created. It may be copied to another application, or exported as a SQL script for importing into an application in another workspace or another APEX instance. It is a self-contained set of attributes, code, and (optionally) file attachments.

When you encounter the requirement a third time, you should be asking yourself, “how can I make this code more re-usable” – because chances are one day you’ll need to fix a bug or make an enhancement to that code, and you’ll want it to be easy to deploy the change wherever it has been used. The first time you encounter this you will probably just do a “copy and paste” to replicate the custom code.

However, there will come a time when some custom code is required, whether some special data processing (using PL/SQL), some special user interface styling (using CSS), or some special user interface behaviour (using JavaScript or jQuery).Īfter you have built an application with (a minimum of) custom code like this, it sometimes happens that the same user requirement crops up again elsewhere whether on another page, another application, or another workspace. “low code”) of the tool will result in applications that are easy to maintain and resistant to regression issues when upgrading. Restricting yourself to only the built-in, declarative features (i.e. The development platform has an excellent range of built-in functionality and components so that almost all user requirements can be covered using standard APEX features. There is a great deal you can build in APEX without even thinking about using a plugin.
