natui entrypoint

Reference run, RunOptions, NatuiApp, components, protocol types, and advanced exports.

The primary entrypoint exports every component plus the Node-driven runtime.

run

function run(
  element: ReactNode,
  options?: RunOptions,
): Promise<NatuiApp>

Starts the host, validates its platform and protocol handshake, sends window properties, and mounts the React element.

RunOptions

RunOptions includes optional title, width, height, minWidth, and minHeight, plus:

Prop

Type

PropertyPurpose
hostHost executable string or { cmd, args? } override

readyTimeoutMsStartup handshake timeout override

Without onClose, closing the native window unmounts React, sends quit, and exits the Node process.

NatuiApp
