How to Create Document Picker in React Native

Hello developers! In this guide, I'll walk you through the process of creating a document picker in a React Native application using the react-native-document-picker library. Document pickers are essential when you want users to upload or select files from their devices, and this library simplifies the implementation process in React Native.

In this tutorial, I'll give very easy and simple steps to create a document picker in react native.

So, let's see how to create a document picker in react native, react native document picker, react-native-document-picker npm, how to upload a document in react native, and how to upload a file in react native.

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

npx react-native init YourDocumentPickerApp
cd YourDocumentPickerApp

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-document-picker library:

npm install react-native-document-picker

Link the library to your project using the following command:

npx react-native link react-native-document-picker

Open your AndroidManifest.xml file and add the following permissions:

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

For iOS, no additional permissions are required.

Now, let's create a component that will serve as our document picker.

// DocumentPickerComponent.js

import React, { useState } from 'react';
import { View, Text, Button } from 'react-native';
import DocumentPicker from 'react-native-document-picker';

const DocumentPickerComponent = () => {
  const [pickedDocument, setPickedDocument] = useState(null);

  const pickDocument = async () => {
    try {
      const result = await DocumentPicker.pick({
        type: [DocumentPicker.types.allFiles],
      });

      console.log(result);

      setPickedDocument(result);
    } catch (err) {
      if (DocumentPicker.isCancel(err)) {
        // Handle document picker cancellation
        console.log('Document picker cancelled');
      } else {
        // Handle other errors
        console.error(`Error picking document: ${err}`);
      }
    }
  };

  return (
    <View>
      <Text>Picked Document: {pickedDocument ? pickedDocument.name : 'None'}</Text>
      <Button title="Pick Document" onPress={pickDocument} />
    </View>
  );
};

export default DocumentPickerComponent;

Now, you can use the DocumentPickerComponent in your main application file or any other component where you want to integrate the document picker.

// App.js

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

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

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

export default App;

Run your React Native application and test the document picker functionality. Make sure it successfully picks documents and handles errors gracefully.

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