Lumigo, a monitoring and debugging platform for serverless applications, has developed an IntelliJ plugin that automatically maps user serverless.yml files, locates functions, and adds a Lumigo icon to open the corresponding function directly in Lumigo. The development of this plugin was a challenge for two frontend developers who had to learn Java and Kotlin to overcome language barriers. They used PSI (Program Structure Interface) files and an add-on called PsiViewer to visualize the code structure. The plugin's functionality includes faster performance, improved product engagement, and better assistance for developers. The plugin's creation was made possible by Lumigo's 10% investment in personal development, allowing employees to use their working time to invest in personal projects or self-development.
