Differences between electron-simple-updater and built-in autoUpdater

  • Actually, autoUpdater is used inside.
  • Linux support.
  • It handles Squirrel.Windows install/update command line arguments.
  • It doesn't require a dedicated release server.
  • You need only 2 lines of code to make it work.

Installation

Install with npm:

npm install --save electron-simple-updater

Usage

Publish a new release

  1. Insert a link to a hosting where you will store updates.json to main.js. You can find a sample of updates.json in the the example

    // Just place this code at the entry point of your application:
    const updater = require('src/index');
    updater.init('https://raw.githubusercontent.com/megahertz/electron-simple-updater/master/example/updates.json');

    You can set this link in package.json:updater.url instead of init() argument.

  2. Build your release using electron-builder or another tool. Note: Your application must be signed for automatic updates on macOS. This is a requirement of Squirrel.Mac.

  3. Upload your release with update.json to a hosting. You can do it manually or use electron-simple-publisher to simplify this process. Note: Squirrel.Mac requires a properly prepared release.json file. A release in the property url must be zipped .app file.

  4. That's it!

    Now your application will check for updates on start and download it automatically if an update is available. After app is restarted a new version will be loaded. But you can customize it to ask a user if he would like to install updates. See the example for details.
