Build a Camera App with React Native Vision Camera | DEVember Day 11

Welcome to Day 11 of DEVember! Today, we will be building a camera app using React Native Vision Camera. React Native Vision Camera is a powerful tool that allows you to access the device’s camera and take photos and videos with ease.

Getting Started

First, make sure you have React Native set up on your machine. If not, you can follow the installation instructions on the official React Native website. Once you have React Native installed, you can create a new project using the following commands:

npx react-native init CameraApp
cd CameraApp

Next, install the React Native Vision Camera package using npm:

npm install react-native-vision-camera

Building the Camera App

Now that we have all the necessary dependencies installed, we can start building our camera app. First, we need to set up the permissions to access the device’s camera. You can do this by adding the following code to your AndroidManifest.xml file:

<uses-permission android:name="android.permission.CAMERA" />

Next, we can create a simple camera component using React Native Vision Camera:

import React from 'react';
import { RNCamera } from 'react-native-vision-camera';

const CameraScreen = () => {
  return (
    <RNCamera style={{ flex: 1 }} />
  );
}

export default CameraScreen;

With this simple code, we now have a functional camera component in our app. You can customize the camera component further by adding features such as flash, focus, and zoom control, as well as capturing and saving photos and videos.

Conclusion

Building a camera app with React Native Vision Camera is a great way to learn how to work with device hardware and access native features. With just a few lines of code, you can create a fully functional camera app that is ready to be deployed to both iOS and Android devices. I hope this tutorial has been helpful in getting you started with building your own camera app with React Native Vision Camera. Happy coding!
