React Native : How to create text file and save it to external storage

Question

I am trying to create a text file using react native for both Android and iOS device. How can we store the string data in text file and and save it to external storage of device. Please suggest if any library for the same.

Answer 1

Use npm package react-native-fs for it..!

Install :

npm i react-native-fs

Creating File Example :

var RNFS = require('react-native-fs');

var path = RNFS.DocumentDirectoryPath + '/test.txt';

// write the file
RNFS.writeFile(path, 'Lorem ipsum dolor sit amet', 'utf8')
  .then((success) => {
    console.log('FILE WRITTEN!');
  })
  .catch((err) => {
    console.log(err.message);
  });

Thank you..!
