Packaging and Distributing Your App (A Sneak Peek)

You've built your first Electron app! That's fantastic. But how do you get it into the hands of your users? For now, we'll just get a glimpse into the world of packaging and distribution. This section is a sneak peek to show you what's possible and to plant the seed for future exploration.

Electron applications are typically distributed as installable packages. This means users can download a file and run an installer, just like any other desktop application they might be familiar with. These packages bundle your application code, the Electron runtime, and all its dependencies into a single, ready-to-install unit.

The most common tool for packaging Electron apps is called 'electron-builder'. It's a powerful and flexible utility that can generate installers for various operating systems, including Windows (.exe, .msi), macOS (.dmg, .app), and Linux (.deb, .rpm, .AppImage). It handles a lot of the complexities for you, making the process significantly smoother.

After installing electron-builder, you'll typically configure it in your package.json file. This configuration tells electron-builder how to build your app, what icons to use, what the application name should be, and much more.

Once configured, you can run a command to initiate the build process. electron-builder will then do its magic, creating the distributable files in a designated output directory.

This command, assuming you've added a build script to your package.json that calls electron-builder, will generate the installer files. The exact output will depend on your configuration and target operating systems.

This is just a taste of what packaging involves. Later in the book, we'll dive deeper into electron-builder, explore different configuration options, and even touch upon code signing and auto-updates. For now, know that getting your app ready for distribution is a well-supported and straightforward process with the right tools.
