Web & NUI

Packages

• The package manager is chosen per project: npm, pnpm, bun or yarn. The default is bun, but an existing lockfile wins.
• One-click Install, Add package (with a dev toggle) and remove
• A "package.json changed · N missing" warning, and an editor banner when an app's imports are missing because nothing is installed yet
• Add FiveM types (@citizenfx/client, @citizenfx/server)

Scripts

Every script in package.json gets Run / Stop and runs in its own named terminal, with a status dot. When a dev server prints its address (Vite's Local:), it shows up as a chip that opens the browser.

ui_page dev / build

The In-game UI card in the manifest form switches ui_page between the dev server and the build, and updates files {} to match.

Chrome 103 compatibility

FiveM's CEF is Chrome 103. K3 Studio warns about newer CSS features and APIs in NUI files, and about a vite config that has no build target.
