How to get files uploaded on FTP server with React native?

Actually, I want to get the files with directory structure uploaded on FTP server using React-native.

I have tried to find libraries but I didn't find anything related to it.

So can you please help me with this problem?

import React, { Component } from 'react';
import { StyleSheet, View, Button } from 'react-native';
import FTP from 'react-native-ftp';

export default class App extends Component {
  onButtonpress() {
     FTP.setup("IP", 21) //Setup host
     FTP.login("username", "password").then(
     (result) => {
        FTP.list(".").then(
          (result) => {
            console.log(result);
        }
      );
    },
   (error) => {
    alert(error);
   }
  )
}
render() {
  return (
    <View >
      <Button onPress={this.onButtonpress.bind(this)} title="hi" />
    </View>
  );
 }
}

Here is the sample i have tried but i got error while impoting 'react-native-ftp'. I got error "Could not find declaration for module 'react-native-ftp'".

The error you encounter is because of react-native-ftp functions are not available on ios - they are not implemented. You need to fork the repo and implement them to work with ios too.

and then:
You can download a file like below using react-native-ftp:

FTP.downloadFile("./nameOfFileToBeDownloaded","localPathWhereItWillBeSaved")
    .then(result=>console.log(result))
    .catch(error=>alert(error))

Or upload with uploadFile:

FTP.uploadFile("./nameOfFileToBeUploaded","remotePathWhereItWillBeSaved")
    .then(result=>console.log(result))
    .catch(error=>alert(error))

If you want entire folder, you can zip it first with react-native-zip-archive and the upload just the zip.
