How Adobe Launch Build works

[#1]

Hi team, 

Just to know how the adobe launch build works? I know the build divided into main library and many smaller files 

but when we build the library for some specific rules for specific web pages, does whole main library (including all scripts of extension, rules, and data elements ) gets rebuilt every time or only targeted?

@thebenrobb can probably answer better than me.

But basically, yes, the whole thing gets rebuilt: everything upstream + anything that's included in your library.

This is correct. Each build is done from scratch based on the exact resources that are upstream and included in your library. The process is repeated when you move from Dev to Stage to Prod.
