How do I create a cache of files that can be drawn from dynamically client-side?

[justuswitmer]

I am trying to build a cache of files that can dynamically be drawn from as needed, where the build process, running occasionally, only needs to create data (using a data loader) for files that haven't been created yet. I currently have a system where I am building and adding files on build time to the src/data folder. Is this the recommended location to put these files? And then how would I dynamically read them from the client side?
