How to Generate Barcode in React Native

Hey developers! Today, I'm excited to guide you through the process of creating a React Native application that generates barcodes using the react-native-barcode-builder library. Barcodes are widely used for various purposes, and this library makes it easy to integrate barcode generation into your React Native projects.

In this tutorial, I'll give you very easy and simple steps to create a barcode in the react native application react-native-barcode-bulider.

So, let's see how to generate barcodes in react native, react native barcode generate, react-native-barcode-builder, and how to create barcodes in react native, react-native barcode.

Make sure you have a React Native project set up. If not, you can create one using:

npx react-native init YourBarcodeGeneratorApp
cd YourBarcodeGeneratorApp

Now, let's get started!

Open a terminal and navigate to your project's root directory. Run the following command to install the react-native-barcode-builder library:

npm install react-native-barcode-builder

Create a component that uses react-native-barcode-builder to generate a barcode.

// BarcodeGeneratorComponent.js

import React, { useState } from 'react';
import { View, TextInput, Button } from 'react-native';
import Barcode from 'react-native-barcode-builder';

const BarcodeGeneratorComponent = () => {
  const [text, setText] = useState('');

  return (
    <View>
      <TextInput
        placeholder="Enter text for barcode"
        value={text}
        onChangeText={(newText) => setText(newText)}
      />
      <Button title="Generate Barcode" onPress={() => {}} />
      {text !== '' && <Barcode value={text} format="CODE128" text={text} />}
    </View>
  );
};

export default BarcodeGeneratorComponent;

Now, let's implement the logic to generate the barcode when the button is pressed.

// BarcodeGeneratorComponent.js

// ... (previous code)

const BarcodeGeneratorComponent = () => {
  const [text, setText] = useState('');
  const [barcodeValue, setBarcodeValue] = useState('');

  const generateBarcode = () => {
    setBarcodeValue(text);
  };

  return (
    <View>
      <TextInput
        placeholder="Enter text for barcode"
        value={text}
        onChangeText={(newText) => setText(newText)}
      />
      <Button title="Generate Barcode" onPress={generateBarcode} />
      {barcodeValue !== '' && <Barcode value={barcodeValue} format="CODE128" text={barcodeValue} />}
    </View>
  );
};

export default BarcodeGeneratorComponent;

Now, integrate the BarcodeGeneratorComponent into your main application file or any other component where you want to generate barcodes.

// App.js

import React from 'react';
import { View, StyleSheet } from 'react-native';
import BarcodeGeneratorComponent from './BarcodeGeneratorComponent';

const App = () => {
  return (
    <View style={styles.container}>
      <BarcodeGeneratorComponent />
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});

export default App;

Run your React Native application and test the barcode generation functionality. Enter different texts, generate barcodes, and ensure they are displayed correctly.

That's it! You've successfully implemented a barcode generator in React Native using the react-native-barcode-builder library.
