Extending with Custom Code

With OutSystems, developers can use Visual Studio to create custom code, publish it and make it available for use in applications. The OutSystems IDE integrates with Visual Studio to enable developers to create extensions to the visual language. These extensions basically wrap standard C# code that can be used in the visual model. Developers are able to:

• Write their own C# code.
• Reuse all of the .NET frameworks.
• Reuse existing libraries.

Here is an example of an extension that wraps the Google Custom Search Engine that is available in the Forge.

A visual API becomes part of the visual language and can be reused across applications. The code becomes part of the visual language and inherits capabilities like: 

• Monitoring: The code will automatically be monitored by the platform. For example, if the code reuses an API, all calls to that API will be measured for performance and logged. Performance reports can be created for them.
• Exception logging: Any exception coming out of those actions is automatically logged and stack traces can be seen in the OutSystems management console.
