I am trying to build a Webpack loader for Gleam language that compiles to JavaScript. Since, gleam has a standalone compiler and compilation unit is entire package as opposed to file-based system of Webpack, I need to maintain the state to avoid the repetitive compilation of the gleam source code.
But, Webpack documentation recommends that loaders should be stateless. Without maintaining the state, it is impossible to keep track of mapping of compiled files and their source gleam files. I also did not find any such documentation about this on Webpack docs.
So, how can I achieve this? Is there some other Webpack process-level API that can be utilized to achieve this?
