Hi everyone, I have been exploring webOS Open Source Edition (OSE) and trying to get a better grasp of its platform architecture. I understand that it’s built on Linux and uses components like Luna Service Bus for inter-process communication. However.., I am curious about a few things: How does webOS OSE handle system services compared to other Linux-based OS platforms: ?? What are the best practices for developing and integrating custom services within the platform: ?? Are there any specific debugging tools recommended for tracking service interactions and performance: ?? I would appreciate any insights from experienced developers working with webOS OSE. Also, if there are any official or community-recommended resources to dive deeper into this, please share them. Looking forward to learning from you all !! I have also read this thread [https://forum.webosose.org/t/are-there-any-good-webos-ose-app-development-tutorials-out-there-](https://forum.webosose.org/t/are-there-any-good-webos-ose-app-development-tutorials-out-there/486)[mulesoft](https://www.igmguru.com/digital-marketing-programming/mulesoft-training) but still looking for more help. Thanks !! With Regards, Derek Theler ---

Hi @deerektheler, I have tried my best to answer your questions, but the scope is quite broad, so my response may be incomplete. ### How does webOS OSE handle system service? webOS OSE manages system services through the Luna bus. The bus acts as an Inter-Process Communication (IPC) mechanism that allows services to communicate directly without relying heavily on traditional D-bus mechanism. ### What are the best practices for developing custom services? - Use the [LS2 API](https://www.webosose.org/docs/guides/getting-started/introduction-to-ls2-api/) - As said earlier, the Luna bus is the primary IPC mechanism in webOS OSE, and LS2 API is one of the best way to use it. - Leverage [the SDK and CLI tools](https://www.webosose.org/docs/tools/) - Refer the [existing services](https://github.com/webosose) ### Debugging tools? There are a few options. - [GDB](https://www.webosose.org/docs/guides/setup/setting-up-debugging/) - [pmlogd & journald](https://www.webosose.org/docs/guides/development/logging/logging-overview/) - [webOS Studio](https://www.webosose.org/docs/tools/sdk/vs-code-extension/#log-viewer) Thanks, ---
