Electron Packager: The Complete Guide to Packaging Electron Apps
Introduction
If you're developing an Electron.js application, packaging and distributing it efficiently across different platforms is crucial. Electron Packager is one of the most widely used tools for bundling Electron apps into standalone executables for Windows, macOS, and Linux.
In this guide, we'll explore what Electron Packager is, how it works, its features, installation process, and step-by-step usage instructions to help you create fully functional Electron apps.
What is Electron Packager?
Electron Packager is an open-source command-line tool that helps developers package Electron applications into standalone executables for different operating systems. It eliminates the need for users to install Node.js or dependencies separately.
🔹 Key Features:
- Cross-platform packaging for Windows, macOS, and Linux
- Ability to package apps for multiple architectures (x64, ia32, arm64, etc.)
- Customization options like app icons, metadata, and ignore files
- Support for various Electron versions
- Efficient file handling to minimize app size

Installing Electron Packager
Before using Electron Packager, ensure you have Node.js and npm installed on your system.
Step 1: Install Node.js and npm
If you don’t have Node.js installed, download it from Node.js official site. npm (Node Package Manager) comes bundled with Node.js.
Step 2: Install Electron Packager
To install Electron Packager globally, use the following command:
npm install -g electron-packager
Or, install it as a dev dependency in your project:
npm install --save-dev electron-packager
How to Use Electron Packager
Once installed, you can package your Electron app into a standalone executable.
Step 1: Navigate to Your Electron App Directory
Move to the directory where your Electron app is located:
cd /path/to/your-electron-app
Step 2: Run Electron Packager Command
Now, run the following command to package your app:
electron-packager . MyApp
This will create a package named MyApp for your current OS.
Customizing Your Package
1. Specify Target Platform and Architecture
You can define the target OS and architecture using:
electron-packager . MyApp --platform=win32 --arch=x64
Supported platforms:
win32(Windows)darwin(macOS)linux(Linux)
Supported architectures:
x64(64-bit)ia32(32-bit)arm64(ARM processors)
To package for multiple platforms simultaneously:
electron-packager . MyApp --platform=win32,darwin,linux --arch=x64,arm64
2. Set Custom App Icon
To include a custom .ico (Windows) or .icns (macOS) icon:
electron-packager . MyApp --icon=/path/to/icon.ico
3. Exclude Unnecessary Files
Reduce package size by ignoring node_modules and dev dependencies:
electron-packager . MyApp --ignore=node_modules/electron
4. Create a Portable Executable
To package a portable Windows app:
electron-packager . MyApp --win32metadata.CompanyName="My Company"
Generating Installable Versions
While Electron Packager creates standalone applications, if you want to generate installable versions, you need tools like:
- electron-builder: GitHub (Creates .exe/.dmg installers)
- electron-forge: GitHub (A complete toolchain for building Electron apps)
Troubleshooting Common Issues
1. Error: Electron Version Not Found
Solution: Ensure you specify the correct Electron version:
electron-packager . MyApp --electron-version=27.0.0
Check Electron versions here.
2. Large App Size
Solution: Ignore unnecessary files:
electron-packager . MyApp --ignore="node_modules/unused-folder"
3. Missing .dll or .so Files
Solution: Ensure all dependencies are bundled using:
npm install --production
Final Thoughts
Electron Packager is an essential tool for developers looking to distribute their Electron applications efficiently. Whether you’re packaging a simple desktop app or a production-ready solution, mastering this tool will help streamline the deployment process.
