Help merging texture packs and adding custom discs to loot tables (or crafting).

I created a data-/resourcepack using this tool: https://juponhuissier.github.io/custom-jukebox/index.html
Now I want to add crafting recipes for those custom discs (implemented by using components and custom models. 
The tool also says that it generates a combined texture- and datapack. What does that mean? How can I split them up and put the resource part in my server resourcepack?
