Introduction to Packaging and Distribution

You've poured your heart and soul into building a fantastic Electron application, and now it's time to share it with the world! Packaging and distribution are the crucial steps that transform your development project into a user-friendly, installable desktop application. This chapter will guide you through the process of preparing your app for your users, ensuring a smooth and professional deployment experience.

Think of packaging as the process of bundling all the necessary files and dependencies your Electron app needs to run into a single, self-contained unit. Distribution is then the act of making that packaged application available to your users, whether it's through direct download, an app store, or a custom installer.

Electron provides powerful tools to help you with both packaging and distribution. We'll explore the most common and effective methods, focusing on making the process as streamlined as possible, especially for those coming from a web development background. Our goal is to equip you with the knowledge to create professional installers for Windows, macOS, and Linux.

Here's what we'll cover in this chapter:

• Understanding the packaging process and its importance.
• Leveraging electron-builder for robust packaging and cross-platform distribution.
• Configuring electron-builder for various platforms and installer types.
• Signing your application for enhanced security and trust.
• Strategies for distributing your application effectively.

Before diving into the tools, it's essential to understand the output of the packaging process. For macOS, this typically means creating a .dmg (disk image) file or a .pkg installer. On Windows, you'll often generate an .exe installer or an .msi package. For Linux, common formats include .deb for Debian-based systems, .rpm for Red Hat-based systems, or an AppImage for cross-distribution compatibility.

We'll primarily focus on electron-builder, a popular and powerful tool that simplifies the creation of these various package formats. It handles many of the complexities of cross-platform building and offers extensive customization options.
