Setup and Host Model

Recommended Setup

fxmanifest.lua:

ui_page 'ui/host.html'
files {
  'ui/host.html',
  'ui/index.html',
  'ui/index.js',
  'ui/index.css'
}

ui/host.html:

<script src="https://cfx-nui-ragemp-fivem-bridge/ui/_bridge.js"></script>

Browser URL Formats

mp.browsers.new accepts:

• Relative URL: "index.html"
• Cross-resource shorthand: "@my-resource/ui/login.html"
• Absolute URL: "https://cfx-nui-my-resource/ui/login.html"
• data:text/html,... payloads

Cross-Resource Warning

Bridge attempts runtime script injection into iframes, but cross-origin resource pages can block that.

Input Forwarding

Host forwards keyboard state (keydown/keyup) to client through NUI callbacks for key manager consistency.
