Hi @Petras_Vestartas

You might take a look at how the LBT folks do their component-swapout:

- [LB Sync Grasshopper File](https://github.com/ladybug-tools/ladybug-grasshopper/blob/master/ladybug_grasshopper/src/LB%20Sync%20Grasshopper%20File.py)
- [ladybug\_rhino.versioning.diff.sync\_component()](https://github.com/ladybug-tools/ladybug-rhino/blob/b3346d7439a990a5bf4b7125038af9a0aa9db7f8/ladybug_rhino/versioning/diff.py#L224C5-L224C19)

For me, a better method has been moving all of the logic of the component out to functions or classes in a package, and them importing those into the component. When you update the package’s logic, it also updates in all your GH-Files.

[@AndersDeleuran](https://discourse.mcneel.com/u/AndersDeleuran) had a good explanation of several other methods for managing your code [in a recent post here.](https://discourse.mcneel.com/t/python-component-in-multiple-gh-files-how-to-keep-updated/174263/5)
