UIT is a library for performant, modular, low-memory file processing at scale, in the Cloud. It works by offering a 4-step process to gather a file hierarchy from any desired modalty, apply filters and transformations, and output it in any desired modality.

- *performance*: speed is of essence when navigating and searching through large amounts of data - *low-memory* by applying streaming and parallelization we can run this in low-memory environments such as Cloudflare workers - *modular*: modularity is beneficial because by making it composable we get a clear high-level overview of all building blocks. also, not all building blocks can be ran in the same runtime or location. UIT has come about after many iterations of the platform of uithub, which started as a simple node-based parser of zipfiles. While building more and more features and add-ons, I found myself limited by the memory a lot as I was not streaming enough, and going back to JSON too early (because using the Streams API is tricky!). Thus, as features and complexity grew the need was born to create a more modular extensible architecture with good serverless practices in mind.
