Integrate IBM Cloud Push Notifications Service with a React Native app using React Native SDKs
About the app
This blog helps you build a React Native app that shows all the repositories of a GitHub Organization. It also sends a push notification when an issue or a pull request is created/updated/closed. IBM Cloud Functions actions trigger the push notifications. The complete app is available here.
Push Notifications Service
Create and configure a Push Notifications Service instance from the IBM Cloud catalog. You can refer to this tutorial to create and configure the instance.
IBM Cloud Functions
IBM Cloud Functions are used to create GitHub actions and triggers. Please refer to the IBM Cloud Functions doc for details.
Create an action to get all repositories
Refer to getReposAction.js to create a Node.js action. Create the action using IBM Cloud Functions.
let orgName = "Gypsyan"; defines the organization of the GitHub. Modify this to be the same name as your GitHub org.
This action retrieves all the repositories of the GitHub org and returns the details of the repositories:
Create an action to listen for Github web-hooks
Create a Node.js action with the code given in ReactNativeAction.js. Make sure to update the
apiHost. Update the values of these attributes as per the Push Notifications Service instance created in the first step. This action uses the openwhisk package, which is a wrapper around the Apache OpenWhisk APIs.
This action tracks the GitHub activity. Based on the activity, a push notification payload is created that triggers a notification.
Create a Cloud Functions trigger
Create a trigger and add the ReactNativeAction in the actions field.
Add the GitHub webhook
Open the GitHub repository settings and add a webhook with IBM Cloud Functions trigger. Select Issues and Pull Request.
GitHub will invoke the IBM Cloud Functions trigger once any issues or pull request event happens in the GitHub org repositories.
Configure the client app—iOS and Android—using the bmd-push-react-native SDK documentation.
Run the app
Run your app using
react-native run-ios or
react-native run-android commands.
Register the device for Push Notifications
Click on the bell icon to register the device for push notifications.
To test the app, create an issue or pull request in any repository of your GitHub organization.
