Exposing assets with loader functions

Earlier in this chapter, we created a robots.txt file and exposed it by placing it into the public folder. However, we can also use loader functions in resource routes to expose assets. This is particularly useful when we want to dynamically create these assets on the fly or manage user access. To get started, follow these steps:
