Fivem Nui

This one's for building user interfaces in FiveM using HTML, CSS, and JavaScript. It covers the essentials: setting up ui_page in your fxmanifest, handling SendNUIMessage and SetNUIFocus for fullscreen UIs, and wiring up NUI callbacks with RegisterNUICallback. The guidance is split across setup, fullscreen patterns, callbacks, and best practices, which is helpful since NUI communication between the client and browser context trips people up constantly. If you're making anything from inventory screens to admin panels, this gives you the FiveM-specific patterns you need without digging through forum posts. Points you to the natives docs when needed, which is the right call.
