# sure\_lib
v2.2.1 Lua 5.4 FiveM
sure\_lib is a modern-first Lua 5.4 utility library for FiveM resources. It gives resource authors focused modules for validation, event safety, reactive state, config loading, entity spawning, cooldown synchronization, database models, ESX transactions, player shortcuts, and Lua-driven NUI rendering.
Add the shared loader, confirm dependencies, and load your first module.
Learn how `sure.getModule(...)` resolves shared, client, and server modules.
Build schemas for events, callbacks, configs, and command payloads.
Scan method signatures, parameters, return values, and runtime availability.
Render bundled NUI pages from Lua node trees, reactive state, and motion components.
This documentation is written for the latest `sure_lib` repository state at commit `30b3cfd` and resource version `2.2.1`.

## Recommended path
Add `shared_script '@sure_lib/init.lua'` to any resource that consumes sure\_lib.
Call `sure.getModule('validator')`, `sure.getModule('lui')`, `sure.getModule('db')`, or another module from the side where it exists.
Use shared modules for cross-side logic, client modules for local player/UI work, and server modules for authoritative database, ESX, or cooldown state.
