Flytre Lib (FlytreLib) - a library for Minecraft that contains many utilities simplifying the support of other mods. It offers an API for recipes, fluids, configuration, and updates.
If there is a question about reloading configurations without restarting the game, there are several options. For client configurations, you can press f3 + t to reload textures and client configurations. Exiting and re-entering the world also serves to reload client configurations. For server configurations, there is the /reloadconfig command to reload them. Additionally, there is a custom key f3 + y that instantly reloads client configurations.
