Push Notifications in PWA Using Firebase and React

In this post, we figure out how to push alerts to the users of PWAs (Progressive Web App) using Google Firebase and React

Many sites send notifications to their users through the browser for various events occurring within the web app. We can easily do this using Cloud Messaging, which allows us to send messages to any device using HTTP requests with Firebase.

Here are the basic steps required for pushing the notifications to a web app using Firebase.

Setup

Firstly, it’s necessary to have a Firebase account. Once you have an account, go to the ‘Create a Project’ section.

For this demo, we are creating the project using the create-react-app command.

In addition to this, we need the Firebase library. For that, open your terminal and run the command npm install firebase –save.

Coding

1. Let’s create a file inside the project directory named push-notification.js. Now we must create a function that initializes Firebase and has the important keys to our project.

In the above image, the function named initializeFirebase() has been called.

• Service Worker:A service worker is used as a script that the browser runs in the background, separate from the web app. It is mainly providing data in the form of local storage cache. Even if we refresh the web page, the locally stored cache doesn’t change.

In the above image, we are importing a service worker (serviceWorker) into the index.js file, where other packages are also imported. Now, after importing it into the index.js file, let’s get that exported by developing a new file called serviceWorker.js, which is served as a service.

In the register function, the default is used so that user can use any name they want to enter in index.js while importing as a user. For example, we can use** “import swore**(or any other name) from. /serviceWorker;” instead of “import serviceWorker from. /serviceWorker;”

If (navigator. serviceWorker. Controller) {} =>This is the point from which the updated pre-cached content has been fetched, but the previous service worker will still serve the older content until all the client’s tabs are closed. New content is available and will be used when all tabs for this page are closed.

Note: You can also check the generated token in the developer mode=>Application=>LocalStorage=>requestedURL=>notification-token. Now, here you get your desired generated token. The value of notification-token(key) is the example of a generated token.

Now, after generating the token we need to call the function. Here, we call it in index.js file wherever we need to generate the token, or you can also call this function on click of a button.

This key is the server key which you can find in your Firebase account:

1. Login to your Firebase account.

2. Go to the project settings through project Overview settings icon.

3. Then go to the Cloud Messaging and there you can easily get the server key for your Firebase account.

Here, you just click to send our request to Postman and everything is good to go.

Note: Remember that notification will only appear when your app is in the background or minimized.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

• Performance: It delivers optimal performance.
• Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
• UI design: React Native enables you to design simple and responsive UI for your mobile app.
• 3rd party plugins: This framework supports 3rd party plugins.
• Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

• Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
• Near-native user experience: React Native provides several native components, and these are platform agnostic.
• The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
