Mobile applications often include images, but they can also be a performance stumbling block. The user experience of your React Native app will be improved if your photos are optimized. We'll walk you through creating a straightforward image compressor with React Native in this article.
Make sure you have the following installed before we start:
- Using npm React Native CLI
- A preferred code editor
Step 1: Create a New React Native Project
Create a new React Native project first. Launch your terminal, then enter:
- npx react-native init ImageCompressor
A new React Native project with the name "ImageCompressor" will be created by this command.
Step 2: Install Dependencies
We'll then install the prerequisites for image compression. To select photos and resize them, we'll use the react-native-image-picker library and react-native-image-resizer.
- npm install react-native-image-picker react-native-image-resizer
Step 3: Link Dependencies
We must link the new native modules to our project because we have added them. Run:
- npx react-native link react-native-image-picker
- npx react-native link react-native-image-resizer
Step 4: Writing the Image Compressor Component
In your src folder, make a new file called ImageCompressor.js and add the following code:
The user can choose an image and then compress it using the component ImageCompressor we've written in this code.
Step 5: Integrating the Component
Open the App.js file and add the following to its contents:
Step 6: Running the App
Lastly, launch your React Native application by typing:
- npx react-native run-android
npx react-native run-ios
In your React Native app, selecting and compressing photos should now be possible.
In this article, we learnt how to use React Native to create a straightforward image compressor. For your app to optimize image sizes, boost performance, and improve user experience, this could be a useful feature. Please feel free to further modify and build upon this example to meet your unique needs.
