refrakt

Runtime helpers for Refrakt, a convention-first web framework for Gleam built on Wisp, Lustre and Mist.

This is the small library that Refrakt apps import at runtime. The code generator lives in the separate refrakt_cli package, which apps only need as a dev-dependency.

gleam add refrakt
gleam add --dev refrakt_cli
