Simple file downloader library for Electron app
- One function call instead of having to manually implement a lot of boilerplate.
- Saves the file to the users Downloads directory instead of prompting.
- Bounces the Downloads directory in the dock when done. (macOS)
- Handles multiple downloads.
- Shows badge count (macOS & Linux only) and download progress. Example on macOS:
$ npm install electron-file-downloader
This is probably what you want for your app.
const {app, BrowserWindow} = require('electron');
require('electron-file-downloader')();
let win;
app.on('ready', () => {
win = new BrowserWindow();
});
This can be useful if you need download functionality in a reusable module.
const {app, BrowserWindow, ipcMain} = require('electron');
const {download} = require('electron-file-downloader');
ipcMain.on('download-btn', (e, args) => {
download(BrowserWindow.getFocusedWindow(), args.url)
.then(dl => console.log(dl.getSavePath()))
.catch(console.error);
});
electronFDl.download(window, url, [options]): Promise<DownloadItem>
Type: BrowserWindow
Window to register the behavior on.
Type: string
URL to download.

This option only makes sense for electronFDl.download()
