You can use Transfer plugin from ionic-native.

import { Transfer } from 'ionic-native';
declare var cordova: any;
download() {
  const fileTransfer = new Transfer();
  let url = 'http://www.example.com/file.pdf';
  fileTransfer.download(url, cordova.file.dataDirectory + 'file.pdf').then((entry) => {
    console.log('download complete: ' + entry.toURL());
  }, (error) => {
    // handle error
  });
