The Factorio Library is a set of high-quality, commonly-used utilities for creating Factorio mods.

Download the latest release from the mod portal unzip it, and put it in your mods directory. You can access libraries provided by flib with require("__flib__/position"), etc.

Add the flib directory to your language server's library. We recommend installing the Factorio modding toolkit and setting it up with the Sumneko Lua language server to get cross-mod autocomplete and type checking.
