    RNWP template supports two types of notifications: Scheduled Notifications Push Notifications To test the notifications before building an app, this should be on a physical device, not an emulator.

    Scheduled Notifications Through scheduled notifications, a notification can be sent to the mobile device every a specific period of time with a specific message. However, there is no much control on the message after the app is published. So if you added the message frequency, title and message body, this will always be same unless the app is updated.

    Push Notifications Through push notifications, you can send custom notifications through some notification platforms. This will give you the flexibility to send the notification messages you like at the time you like. This should also be configured through userConfig. This could be handled with ios without the need for firebase. However, this would need some configuration for android mobiles through firebase and then through updating app.

    Firebase configuration First of all, you will need to create an account on Firebase. You can sign in with your Google account. You should then configure the app. Testing Push Notifications Push notifications can be preliminarily tested through the Expo push notifications tool. You will need to provide the device notification token, during testing, this can be shown in the console if you are using VSCode, you can see it in the terminal. It starts with ExponentPushToken as shown below: In order to test the push notifications on an iPhone, you will need to install a custom ios expo client, you can follow the steps in this link.

    Adding Firebase Server Key to your app One final step shall be needed to link the app to your Firebase account, this shall be to upload the Firebase key to Expo push servers. To get the server key, you can do the following steps: Open the Firebase console for the app you created. Click the gear icon in the Firebase app sidebar. Click on the Cloud Messaging option.

    You will find your Server Key. Copy it. Now, your app is ready to send push notifications. Sending Notifications to Registered Phones In order to send notifications to all devices, this will need to store the registered tokens in a database and send notifications to them through an external platform.

    This plugin has been tested with RNWP template. Notifications work well but devices and messages may not show always in the WordPress admin dashboard. To store the device tokens in Firebase, you shall open your Firebase console, you will create a Realtime Database. You can then create a web app to get the config object, it will look like this: You will then need to copy the data between curly braces in this file to the object in ".

    You should alse set the enableFirebase in userConfig. Afterward, when the app opens, it will send a query to store the device token in Firebase. To get all device tokens and send them the push notification. This shall need to write a backend code from a server. Share this:.

    Live Updates With Queues, WebSockets, and Push Notifications. Part 2: React Native Apps with Expo

    Application Development Push notifications are an integral part of mobile app development these days, but many developers, myself included, cannot even think about implementing them without breaking into a cold sweat. Enter Expo. Expo is an amazing set of tools that vastly simplifies native development on iOS and Android. Getting Started To demonstrate notifications, we will use Create React Native App, easily installable via yarn or npm.

    The following directions are paraphrased from their excellent getting started tutorial. Run either npm install -g create-react-native-app or yarn global add create-react-native-app. Voila, a native app, running on your phone. Register for notifications The first thing we have to do, now that we have an app initialized, is to deal with registering push notifications. You can already have permissions for notifications granted, not yet granted, or declined. Next, it requests a push token from Expo, asynchronously.

    Then it defines a notification handler, in case the notification is sent while the app is in foreground, and finally it sets the token in the component state for use in the UI and in other functions.

    To achieve this, we can write another function to send a push notification, given a token, title, and body. The full source code for App. The app has two buttons: a register and a send button. First, hit the register button and the device token field will show up. Where to go next You can take this proof of concept in a lot of different directions.

    Thanks to Expo, all of this flow can be done on the device, if your target workflow is simple enough. But the next logical step would be to write a server side device token store. This way you can save the token with user information to be used later.

    You could even go as far as creating a UI dashboard to send notifications through, and to view and manage your users from.
