Download file from server into Ionic2 App

Question

I am in need to implement a feature in my Ionic2 app where users can download a specific Video file into Ionic2 app.

Upon checking the Ionic Native section, I found that the following plugins available :

• File
• File Chooser
• File Opener
• File Path

But could not find anything such as 'cordova-plugin-file-transfer' where a specific method exists as DOWNLOAD.

What could be the way out ?

Please suggest.

Answer 1

You should use "Transfer" plugin for downloading a file in ionic2

You can install plugin by this command

ionic plugin add cordova-plugin-file-transfer
npm install --save @ionic-native/transfer

and then import it

import { Transfer, FileUploadOptions, TransferObject } from '@ionic-native/transfer';

set constructor

constructor(private transfer: Transfer, private file: File) { }

Then use this function to download file using url

download() {
const url = 'http://www.example.com/file.pdf';
fileTransfer.download(url, this.file.dataDirectory + 
'file.pdf').then((entry) => {
console.log('download complete: ' + entry.toURL());
}, (error) => {
// handle error
});
}

Hope it help you You can also upload a file using this Plugin
