Requirements

This tool requires Node 10 or greater, fakeroot, and dpkg to build the .deb package.

I'd recommend building your packages on your target platform, but if you insist on using Mac OS X, you can install these tools through Homebrew:

``
$ brew install fakeroot dpkg
`

Installation

For use from command-line:

`
$ npm install -g electron-installer-debian
`

For use in npm scripts or programmatically:

`
$ npm install --save-dev electron-installer-debian
`

Usage

Say your Electron app lives in path/to/app, and has a structure like this:

`
.
├── LICENSE
├── README.md
├── node_modules
│   ├── electron-packager
│   └── electron
├── package.json
├── resources
│   ├── Icon.png
│   ├── IconTemplate.png
│   └── IconTemplate@2x.png
└── src
├── index.js
├── main
│   └── index.js
└── renderer
├── index.html
└── index.js
`

You now run electron-packager to build the app for Debian:

`
$ electron-packager . app --platform linux --arch x64 --out dist/
`

And you end up with something like this in your dist folder:

`
.
└── dist
   └── app-linux-x64
   ├── LICENSE
   ├── LICENSES.chromium.html
   ├── content_shell.pak
   ├── app
   ├── icudtl.dat
   ├── libgcrypt.so.11
   ├── libnode.so
   ├── locales
   ├── natives_blob.bin
   ├── resources
   ├── snapshot_blob.bin
   └── version
`

How do you turn that into a Debian package that your users can install?

$3

If you want to run electron-installer-debian straight from the command-line, install the package globally:

`
$ npm install -g electron-installer-debian
`

And point it to your built app:

`
$ electron-installer-debian --src dist/app-linux-x64/ --dest dist/installers/ --arch amd64
`

You'll end up with the package at dist/installers/app_0.0.1_amd64.deb.

$3

If you want to run electron-installer-debian through npm, install the package locally:

`
$ npm install --save-dev electron-installer-debian
`

Edit the scripts section of your package.json:

`json
{
"name": "app",
"description": "An awesome app!",
"version": "0.0.1",
"scripts": {
"start": "electron .",
"build": "electron-packager . app --platform linux --arch x64 --out dist/",
"deb64": "electron-installer-debian --src dist/app-linux-x64/ --dest dist/installers/ --arch amd64"
},
"devDependencies": {
"electron-installer-debian": "^0.6.0",
"electron-packager": "^9.0.0",
"electron": "~1.7.0"
}
}
`

_Note: The versions in devDependencies are examples only, please use the latest package versions
when possible._

And run the script:

`
$ npm run deb64
`

You'll end up with the package at dist/installers/app_0.0.1_amd64.deb.

$3

Install the package locally:

`
$ npm install --save-dev electron-installer-debian
`

And write something like this:

`javascript
const installer = require('electron-installer-debian')

const options = {
src: 'dist/app-linux-x64/',
dest: 'dist/installers/',
arch: 'amd64'
}

async function main (options) {
console.log('Creating package (this may take a while)')
try {
await installer(options)
console.log(Successfully created package at ${options.dest})
} catch (err) {
console.error(err, err.stack)
process.exit(1)
}
}
main(options)
`

You'll end up with the package at dist/installers/app_0.0.1_amd64.deb.

_Note: As of 1.0.0, the Node-style callback pattern is no longer available. You can use
util.callbackify if this is
required for your use case._

$3

Even though you can pass most of these options through the command-line interface, it may be easier to create a configuration file:

`javascript
{
"dest": "dist/installers/",
"icon": "resources/Icon.png",
"compression": "gzip",
"categories": [
"Utility"
],
"lintianOverrides": [
"changelog-file-missing-in-native-package"
]
}
`

And pass that instead with the config option:

`
$ electron-installer-debian --src dist/app-linux-x64/ --arch amd64 --config config.json
`

Anyways, here's the full list of options:

#### src
Type: String
Default: undefined

Path to the folder that contains your built Electron application.

#### dest
Type: String
Default: undefined

Path to the folder that will contain your Debian installer.

#### rename
Type: Function
Default: function (dest, src) { return path.join(dest, src); }

Function that renames all files generated by the task just before putting them in your dest folder.

#### options.name
Type: String
Default: package.name || "electron"

Name of the package (e.g. atom), used in the Package field of the control specification.

According to the Debian Policy Manual:

> Package names [...] must consist only of lower case letters (a-z), digits (0-9), plus (+) and minus (-) signs, and periods (.). They must be at least two characters long and must start with an alphanumeric character.

electron-installer-debian will try to help conform to these requirements by lowercasing the name
provided and replacing any invalid characters with -s.

#### options.productName
Type: String
Default: package.productName || package.name

Generic name of the application (e.g. Text Editor), used in the GenericName field of the desktop specification.

#### options.description
Type: String
Default: package.description

Short description of the application, used in the Description field of the control specification.

#### options.productDescription
Type: String
Default: package.productDescription || package.description

#### options.icon

$3

The package installs the Electron application into /usr/lib, since there are
architecture-specific files in the package. There was a discussion in the issue
tracker about the
installation directory.

In versions of electron-installer-debian prior to 0.5.0, the app was (incorrectly) installed in
/usr/share.
