React Native Show Progress bar While Loading WebView

This example is sort of extension of our previous post of Webview Example in which we have loaded the HTML page from URL. Here is the example of how to Show Progress bar While Loading WebView. As it is the import topic to cover so we decided to cover it separately.

In this example, we will show the ActivityIndicator while the webpage is loading this will help the user to understand that application is doing some task. If we do not apply the progress bar and web page took some extra time to load then the user will be confused that the application is not working so we suggest you use Progress Bar if you are using WebView to load the webpage.

We have to add renderLoading prop in WebView in which we will return the view which we want to show while the page is loading. For this example, we will return the ActivityIndicator like

Render WebView Using

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use WebView you need to install react-native-webview dependency. To install this dependency open the terminal and jump into your project

Run the following commands

This command will copy the dependency into your node_module directory. –save is optional, it is just to update dependency in your package.json file.

CocoaPods Installation

After the updation of React Native 0.60, they have introduced autolinking so we do not require to link the library but need to install pods. So to install pods use

Now open App.js in any code editor and replace the code with the following code.

App.js

(Use if you want to show the loader once when opening a web URL)

App.js (Updates)

(Use if you want to show the loader every time whenever you click on links in Webview)

To Run the React Native App

Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running
react-native run-ios (macOS only).
