Package your Electron app into OS-specific bundles (
Electron Packager is a command line tool and Node.js library that bundles Electron-based application source code with a renamed Electron executable and supporting files into folders ready for distribution.
For creating distributables like installers and Linux packages, consider using either Electron Forge (which uses Electron Packager internally), or one of the related Electron tools, which utilizes Electron Packager-created folders as a basis.
Note that packaged Electron applications can be relatively large. A zipped, minimal Electron
application is approximately the same size as the zipped prebuilt binary for a given target
platform, target arch, and Electron version
Electron Packager is known to run on the following host platforms:
It generates executables/bundles for the following target platforms:
win32, for both 32/64 bit)
darwin) / Mac App Store (also known as
* Note for macOS / Mac App Store target bundles: the
.app bundle can only be signed when building on a host macOS platform.
This module requires Node.js 8.0 or higher to run. On macOS/Linux, the
unzip program is required. On Windows, both .NET Framework 4.5 or higher and Powershell 3 or higher are required.
# For use in npm scripts (recommended) npm install electron-packager --save-dev # For use from the CLI npm install electron-packager -g
Building an Electron app for the Windows target platform requires editing the
Currently, Electron Packager uses node-rcedit to accomplish
this. A Windows executable is bundled in that Node package and needs to be run in order for this
functionality to work, so on non-Windows host platforms, Wine 1.6 or
later needs to be installed. On macOS, it is installable via Homebrew.
Running electron-packager from the command line has this basic form:
electron-packager <sourcedir> <appname> --platform=<platform> --arch=<arch> [optional flags...]
<out>/<appname>-<platform>-<arch>(this can be customized via an optional flag)
--arch can be omitted, in two cases:
--allinstead, bundles for all valid combinations of target platforms/architectures will be created.
appname is omitted, this will use the name specified by "productName" or "name" in the nearest package.json.
Characters in the Electron app name which are not allowed in all target platforms' filenames
/), will be replaced by hyphens (
You should be able to launch the app on the platform you built for. If not, check your settings and try again.
Be careful not to include
node_modules you don't want into your final app. If you put them in
devDependencies section of
package.json, by default none of the modules related to those
dependencies will be copied in the app bundles. (This behavior can be turned off with the
--no-prune flag.) In addition, folders like
node_modules/.bin will be ignored by
default. You can use
--ignore to ignore files and folders via a regular expression (not a
glob pattern). Examples include
Let's assume that you have made an app based on the electron-quick-start repository on a macOS host platform with the following file structure:
foobar ├── package.json ├── index.html ├── […other files, like the app's LICENSE…] └── script.js
…and that the following is true:
electron-packageris installed globally
package.jsonhas been set to

package.json, and set to the exact version of

Foo Barapp has been run at least once
When one runs the following command for the first time in the
electron-packager will do the following:
archfrom the host, in this example,
foobar/Foo Bar-darwin-x64/(since an
outdirectory was not specified, it used the current working directory)
The file structure now looks like:
foobar ├── Foo Bar-darwin-x64 │ ├── Foo Bar.app │ │ └── […Mac app contents…] │ ├── LICENSE [the Electron license] │ └── version ├── […other application bundles, like "Foo Bar-win32-x64" (sans quotes)…] ├── package.json ├── index.html ├── […other files, like the app's LICENSE…] └── script.js
Foo Bar.app folder generated can be executed by a system running macOS, which will start the packaged Electron app. This is also true of the Windows x64 build on a system running a new enough version of Windows for a 64-bit system (via
Foo Bar-win32-x64/Foo Bar.exe), and so on.
These Node modules utilize Electron Packager API hooks:
