Create a Flatpak package for your Electron app.
npm install electron-installer-flatpakCreate a flatpak for your Electron app. This is based off the
electron-installer-debian
tool. Add flatpak support to an electron app using electron-packager
with minimal configuration.
This tool requires flatpak and flatpak-builder >= 0.8.2 to be installed on
your system. See http://flatpak.org/getting.html
Building an electron flatpak requires installing a "base" flatpak
application with electron library dependencies. That base will be autoinstalled
during an app build.
Actually running the apps will require the freedesktop runtime to be installed.
If you already are running flatpak apps you may have the freedesktop runtime
installed. The following example will install the freedesktop runtime for both
i386 and x86_64.
```
flatpak --user remote-add --from gnome https://sdk.gnome.org/gnome.flatpakrepo
flatpak --user install gnome org.freedesktop.Platform/x86_64/1.4 org.freedesktop.Platform/i386/1.4
For use from command-line:
``
$ npm install -g electron-installer-flatpak
For use in npm scripts or programmatically:
``
$ npm install --save-dev electron-installer-flatpak
Say your Electron app lives in path/to/app, and has a structure like this:
``
.

You now run electron-packager to build the app for flatpak:
``
$ 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

└── version
How do you turn that into a flatpak package that your users can install?
If you want to run electron-installer-flatpak straight from the command-line, install the package globally:
``
$ npm install -g electron-installer-flatpak
And point it to your built app:
``
$ electron-installer-flatpak --src dist/app-linux-x64/ --dest dist/installers/ --arch x64
You'll end up with the package at dist/installers/app_0.0.1_x64.flatpak.
If you want to run electron-installer-flatpak through npm, install the package locally:
``
$ npm install --save-dev electron-installer-flatpak
Edit the scripts section of your package.json:
`js`
{
"name": "app",
"description": "An awesome app!",
"version": "0.0.1",
"scripts": {
"start": "electron .",
"build": "electron-packager . app --platform linux --arch x64 --out dist/",
"flatpak64": "electron-installer-flatpak --src dist/app-linux-x64/ --dest dist/installers/ --arch x64"
},
"devDependencies": {
"electron-installer-flatpak": "*",
"electron-packager": "*",
"electron-prebuilt": "*"
}
}
And run the script:
``
$ npm run flatpak64
You'll end up with the package at dist/installers/app_0.0.1_x64.flatpak.
Install the package locally:
``
$ npm install --save-dev electron-installer-flatpak
And write something like this:
`js
var installer = require('electron-installer-flatpak')
var options = {
src: 'dist/app-linux-x64/',
dest: 'dist/installers/',
arch: 'x64'
}
console.log('Creating package (this may take a while)')
installer(options, function (err) {
if (err) {
console.error(err, err.stack)
process.exit(1)
}
console.log('Successfully created package at ' + options.dest)
})
`
You'll end up with the package at dist/installers/app_0.0.1_x64.flatpak.
Even though you can pass most of these options through the command-line interface, it may be easier to create a configuration file:
`js`
{
"dest": "dist/installers/",
"icon": "resources/Icon.png",
"categories": [
"Utility"
]
}
And pass that instead with the config option:
``
$ electron-installer-flatpak --src dist/app-linux-x64/ --arch x64 --config config.json
Anyways, here's the full list of options:
#### src
Type: Stringundefined
Default:
Path to the folder that contains your built Electron application.
#### dest
Type: Stringundefined
Default:
Path to the folder that will contain your flatpak installer.
#### rename
Type: Functionfunction (dest, src) { return path.join(dest, src); }
Default:
Function that renames all files generated by the task just before putting them in your dest folder.
#### options.id
Type: Stringio.atom.electron
Default:
App id of the flatpak, used in the id field of a flatpak-builder manifest.
#### options.productName
Type: Stringpackage.productName || package.name
Default:
Name of the application (e.g. Atom), used in the Name field of the desktop specification.
#### options.genericName
Type: Stringpackage.genericName || package.productName || package.name
Default:
Generic name of the application (e.g. Text Editor), used in the GenericName field of the desktop specification.
#### options.description

Default:
Short description of the application, used in the Comment field of the desktop specification.
#### options.branch
Type: Stringmaster
Default:
Release branch of the flatpak, used in the branch field of a flatpak-builder manifest.
#### options.base
Type: Stringio.atom.electron.BaseApp
Default:
Base app to use when building the flatpak, used in the base field of a flatpak-builder manifest.
#### options.baseVersion
Type: Stringmaster
Default:
Base app version, used in the base-version field of a flatpak-builder manifest.
#### options.baseFlatpakref
Type: Stringhttps://s3-us-west-2.amazonaws.com/electron-flatpak.endlessm.com/electron-base-app-master.flatpakref
Default:
Url of a flatpakref to use to auto install the base application.
#### options.runtime

Default:
Sdk id, used in the sdk field of a flatpak-builder manifest.
#### options.arch
Type: Stringundefined
Default:
Machine architecture the package is targeted to. Suggested to use node style
arches here ('ia32', 'x64'), which will be converted to flatpak style arches
('i386', 'x86_64') when calling into the actual flatpak commands. Directly
using flatpak style arches is also supported.
#### options.finishArgs
Type: Array[String]`
Default:js`
[
// X Rendering
'--socket=x11', '--share=ipc',
// Open GL
'--device=dri',
// Audio output
'--socket=pulseaudio',
// Read/write home directory access
'--filesystem=home',
// Chromium uses a socket in tmp for its singleton check
'--filesystem=/tmp',
// Allow communication with network
'--share=network',
// System notifications with libnotify
'--talk-name=org.freedesktop.Notifications'
],
Arguments to use when call flatpak build-finish, use in the finish-args field of a flatpak-builder manifest.
Changing this can be used to customize permissions of the sandbox the flatpak will run in.
#### options.files
Type: Array[Array[source, dest]]`
Default:js`
[],
Files to copy directly into the app. Should be a list of [source, dest] tuples.
Source should be a relative/absolute path to a file/directory to copy into the
flatpak, and dest should be the path inside the app install prefix (e.g.
/share/applications/)
Application assets and code will be fully handled by electron-packager, but
this is a useful way to install things such as appstream metadata for an app,
or dbus configuration files.
#### options.symlinks
Type: Array[Array[target, location]]`
Default:js`
[],
Symlinks to create in the app files. Should be a list of [target, location]
symlink tuples. Target can be either a relative or absolute path inside the app
install prefix, and location should be a absolute path inside the prefix to
create the symlink at.
#### options.modules
Type: Array[Object][]
Default:
This option can be used to build extra software modules into the flatpak
application sandbox. Most electron applications will not need this, but if you
are using native node modules that require certain libraries on the system, this
may be necessary. For example, to build libgit2
to use with nodegit, add the following to
your modules list.
``
modules: [
{
name: 'libgit2',
cmake: true,
configOpts: [ '-DBUILD_SHARED_LIBS:BOOL=ON', '-DTHREADSAFE=ON' ],
sources: [{
type: 'git',
url: 'https://github.com/libgit2/libgit2.git',
branch: 'maint/v0.24'
}]
}
]
See the modules field of a flatpak-builder manifest for more details.
#### options.bin
Type: Stringpackage.name
Default:
Relative path to the executable that will act as binary for the application, used in the Exec field of the desktop specification.
The generated package will contain a symlink /usr/bin/<%= options.name %> pointing to the path provided here.
For example, providing this configuration:
`js`
{
src: '...',
dest: '...',
name: 'foo',
bin: 'resources/cli/launcher.sh'
}
Will create a package with the following symlink:
``
usr/bin/foo@ -> ../lib/foo/resources/cli/launcher.sh
And a desktop specification with the following Exec key:
``
Exec=foo %U
#### options.icon
Type: String or Object[String:String]undefined
Default:
Path to a single image that will act as icon for the application:
`js`
{
icon: 'resources/Icon.png'
}
Or multiple images with their corresponding resolutions:
`js`
{
icon: {
'48x48': 'resources/Icon48.png',
'64x64': 'resources/Icon64.png',
'128x128': 'resources/Icon128.png',
'256x256': 'resources/Icon256.png'
}
}
#### options.categories
Type: Array[String][]
Default:
Categories in which the application should be shown in a menu, used in the Categories field of the desktop specification.
For possible values check out the Desktop Menu Specification.
#### options.mimeType
