Server

Compatibility

This script works with other popular inventory systems, like es_extended, qb-inventory, and ox_inventory

For ESX and QBCore functions, the setup is done automatically. But, if you want to keep using exports from ox_inventory or qb-inventory for compatibility, you need to turn on this option in the file: jaksam_inventory/integrations/sv_integrations.lua
