Application registration

Use registerApplication when you supply your own entry file. The app generator calls it for you; generated App.js files only export the root component.

import React from 'react';
import {Chrome, Text, View, registerApplication} from 'react-kindle';

function App() {
  return <View style={{flex: 1, padding: 24}}><Text>Reader</Text></View>;
}

registerApplication({
  id: 'com.lab126.Reader',
  firmware: '5.19.6',
  component: App,
  chrome: Chrome.none,
});

Set firmware to the device release. The ID must match the launcher's --name Reader argument.

Options

Option	Description
id	Required com.lab126.NAME; NAME begins with a letter and contains only letters and digits.
component	Required React root component.
firmware	Required dotted numeric firmware release.
chrome	Initial mode; defaults to Chrome.none.
presentation	Optional classic or unified styling override.
fontScale	Optional positive scale override.
onRequestClose	Called on native shutdown requests. Your app supplies the exit integration.
onLayout	Receives root window layout events.

Registration installs KindleProvider, the native root window, style defaults, and managed lifecycle listeners. It returns a function that removes those listeners; that function does not terminate the process.

In generated apps, export onRequestClose and onWindowLayout from App.js to supply the callbacks. See application lifecycle for managed launch and shutdown.

Chrome modes

Constant	Value	Use
Chrome.automatic	0	Let the system select chrome.
Chrome.none	1	No system chrome.
Chrome.status	2	Status bar.
Chrome.navigation	3	Status and navigation bars.
Chrome.full	4	Full system chrome mode.

Set the numeric mode in app.json, or use the constants in JavaScript. See system chrome for title and menu configuration.
