react-native-nitro-background

This library is reworked fork of react-native-background-actions by Rapsssito.

Powered by Nitro

Installation

npm install @nfsmonstr/react-native-nitro-background react-native-nitro-modules

> `react-native-nitro-modules` is required as this library relies on [Nitro Modules](https://nitro.margelo.com/).

Linking the package manually is not required anymore with Autolinking.

Android

You need to add POST_NOTIFICATION permission to your android manifest, and request this permission before running tatsks

    <uses-permission android:name="android.permission.POST_NOTIFICATIONS" />

iOS

1. Install pods: cd ios && pod install && cd ..
2. The background support requires you to activate the background capability in Xcode.
3. To support submitting the app to the App store you need to add the following to your Info.plist:

     <key>BGTaskSchedulerPermittedIdentifiers</key>
     <array>
         <string>$(PRODUCT_BUNDLE_IDENTIFIER)</string>
     </array>

Usage

Example code

import BackgroundService from '@nfsmonstr/react-native-nitro-background';

const sleep = (time) => new Promise((resolve) => setTimeout(() => resolve(), time));

// You can do anything in your task such as network requests, timers and so on,
// as long as it doesn't touch UI. Once your task completes (i.e. the promise is resolved),
// React Native will go into "paused" mode (unless there are other tasks running,
// or there is a foreground app).
const veryIntensiveTask = async (taskDataArguments) => {
  // Example of an infinite loop task
  const { delay, taskKey } = taskDataArguments;
  await new Promise( async (resolve) => {
    for (let i = 0; BackgroundService.isRunning(taskKey); i++) {
      console.log(i);
      await sleep(delay);
    }
  });
};

const options = {
  notificationOptions: {
    channelName: 'My notification channel',
    channelDescription: 'My notification channel description',
    channelId: 'MY_CHANNEL_ID',
    taskTitle: 'ExampleTask title',
    taskDesc: 'ExampleTask description',
    taskIcon: {
      name: 'ic_launcher',
      type: 'mipmap',
    },
    color: '#ff00ff',
    linkingURI: 'yourSchemeHere://chat/jane', // See Deep Linking for more info
  },
  parameters: {
    delay: 1000,
    taskKey: 'MY_TASK',
  },
};


BackgroundService.start('MY_TASK', veryIntensiveTask, options);
BackgroundService.updateNotification('MY_TASK', {taskDesc: 'New ExampleTask description'}); // Only Android, iOS will ignore this call
// iOS will also run everything here in the background until .stop() is called
BackgroundService.stop('MY_TASK');

If you call stop() on background no new tasks will be able to be started!
