slicer visual - source code

Hi. I am looking for the source code for all of the PBI visuals, I can only find it for some sample ones. Specifically right now I am looking for the slicer code. Where can I find the code for all the visuals that are in PBI?

The below link is incomplete and the sample slicer is not the same as the slicer in PBI:
https://microsoft.github.io/PowerBI-visuals/samples/

Thank you.
