Expo SDK Basic integration guide

This section contains information on how to integrate the Pushwoosh Expo SDK into your application.

To integrate the Pushwoosh Expo SDK into your app, you will need the following:

Install the Pushwoosh Expo plugin using the Expo CLI

expo install pushwoosh-expo-plugin

Install Pushwoosh React Native SDK

npm install pushwoosh-react-native-plugin --save

Add the plugin to the front of the plugin array with the necessary properties:

{
  "expo": {
    "plugins": [
      [
        "pushwoosh-expo-plugin",
        {
          "mode": "development",
          "ios": {
            "PW_API_TOKEN": "__YOUR_DEVICE_API_TOKEN__"
          },
          "android": {
            "apiToken": "__YOUR_DEVICE_API_TOKEN__"
          }
        }
      ]
    ]
  }
}

In the root component of your application:

• Import the pushwoosh-react-native-plugin plugin.
• Initialize the Pushwoosh SDK.
• Call register() in your initialization logic to register for push notifications.

import Pushwoosh from 'pushwoosh-react-native-plugin';

Pushwoosh.init({
    "pw_appid": "__YOUR_APP_ID__" ,
    "project_number": "__YOUR_FCM_SENDER_ID__"
});

Pushwoosh.register();

Where:

• __YOUR_APP_ID__ is the application code from the Pushwoosh Control Panel.
• __YOUR_FCM_SENDER_ID__ is the Firebase project number from the Firebase Console.

Add Firebase configuration file:

1. Copy your google-services.json file to the root directory of the project.
2. Set the googleServicesFile property to the path of your google-services.json and specify the package property:

  "expo": {
    "name": "sample",
    "android": {
      "package": "com.pushwoosh.sample",
      "googleServicesFile": "./google-services.json"
    }
  }

Set bundleIdentifier property to the ios object:

  "expo": {
    "name": "sample",
    "ios": {
      "bundleIdentifier": "com.pushwoosh.sample"
    }
  }

Generate native code and configure the dependencies for each platform by running prebuild:

npx expo prebuild

1. Build and run the project:

npx expo run:android

npx expo run:ios

2. Go to the Pushwoosh Control Panel and send a push notification.
3. You should see the notification in the app.

At this stage, you have already integrated the SDK and can send and receive push notifications. Now, let’s explore the core functionality

In the Pushwoosh SDK there are two event listeners, designed for handling push notifications:

• onPushReceived event is triggered, when a push notification is received
• onPushAccepted event is triggered, when a user opens a notification

You should set up these event listeners right after initialization of the SDK at the application start up:

import { DeviceEventEmitter } from 'react-native';
import Pushwoosh from 'pushwoosh-react-native-plugin';

class PushwooshNotificationHandler {
  setupPushListeners(): void {

    DeviceEventEmitter.addListener("pushReceived", (e) => {
      console.warn("Push Received: " + JSON.stringify(e));
    });

    DeviceEventEmitter.addListener("pushOpened", (e) => {
      console.warn("Push Opened:" + JSON.stringify(e));
    });

  }
}

By focusing on individual user behavior and preferences, you can deliver personalized content, leading to increased user satisfaction and loyalty

import Pushwoosh from 'pushwoosh-react-native-plugin';

class Registration {
  afterUserLogin(user: User): void {

    // Set user ID
    Pushwoosh.setUserId(user.getId());

    // Set user email
    Pushwoosh.setEmails(user.getEmailList());

    // Setting additional user information as tags for Pushwoosh
    Pushwoosh.setTags({
      "age": user.getAge(),
      "name": user.getName(),
      "last_login": user.getLastLoginDate()
    });
  }
}

Tags are key-value pairs assigned to users or devices, allowing segmentation based on attributes like preferences or behavior, enabling targeted messaging.

import Pushwoosh from 'pushwoosh-react-native-plugin';

class UpdateUser {
  afterUserUpdateProfile(user: User): void {

    // Set list of favorite categories
    Pushwoosh.setTags({
      "favorite_categories": user.getFavoriteCategoriesList()
    });

    // Set payment information
    Pushwoosh.setTags({
      "is_subscribed": user.isSubscribed(),
      "payment_status": user.getPaymentStatus(),
      "billing_address": user.getBillingAddress()
    });
  }
}

Events are specific user actions or occurrences within the app that can be tracked to analyze behavior and trigger corresponding messages or actions

class Registration {

  // Track login event
  afterUserLogin(user: User): void {
    Pushwoosh.postEvent("login", {
      "name": user.getName(),
      "last_login": user.getLastLoginDate()
    });
  }

  // Track purchase event
  afterUserPurchase(product: Product): void {
    Pushwoosh.postEvent("purchase", {
      "product_id": product.getId(),
      "product_name": product.getName(),
      "price": product.getPrice(),
      "quantity": product.getQuantity()
    });
  }
}

You must add a Notification Service Extension target to your project. This is essential for accurate delivery tracking and features like Rich Media on iOS.

Follow the native guide’s steps to add the extension target and the necessary Pushwoosh code within it.

If you encounter any issues during the integration process, please refer to the support and community section.

Make sure your Firebase googleServicesFile property is set up in the Expo configuration file and the google-services.json file is added to the root directory of your project:

"expo": {
  "name": "sample",
  "android": {
    "package": "com.pushwoosh.sample",
    "googleServicesFile": "./google-services.json"
  }
}

You might encounter the error, when attempting to run the app on a device.
To resolve the issue, make sure you’ve completed the prebuild step. It generates the native code and configures the dependencies for each platform.

npx expo prebuild
