Snapcraft builds on top of the Electron desktop application framework to create snaps for people to install on Linux.

What problems do snaps solve for Electron applications?

Compared to Mac and Windows, distributing an Electron application for Linux and reaching the widest possible audience was complicated. How applications are packaged and delivered varies from distribution to distribution. With snapcraft it’s just one command to produce a bundle that works anywhere.

Here are some snap advantages that will benefit many Electron projects:

  • Simplify installation instructions, regardless of distribution, to snap install myelectronapp.
  • Directly control the delivery of automatic application updates.

How long will this guide take to complete?

Typically this guide will take around 20 minutes and will result in a working Electron app in a snap. Once complete, you’ll understand how to package Electron applications as snaps and deliver them to millions of Linux users. After making the snap available in the store, you’ll get access to installation metrics and tools to directly manage the delivery of updates to Linux users.

Getting started

Note: We strongly recommend using an Ubuntu 16.04 host, VM or container for this guide. While it is possible to use newer releases of Ubuntu, or other Linux distributions, this may result in incorrect libraries being pulled into the build.

By way of an example, let’s take a look at how a snap is created for the Electron Quickstart app.

Electron Quickstart

Using electron-builder and a few lines of additional configuration in the package.json file an Electron project can be adapted to produce snaps. We’ll break this down.

  "name": "electron-quick-start",
  "version": "1.0.0",
  "description": "A minimal Electron application",
  "main": "main.js",
  "scripts": {
    "start": "electron .",
    "dist": "build"
  "build": {
    "appId": "io.snapcraft.quick-start",
    "linux": {
      "target": ["snap"]
  "repository": "https://github.com/electron/electron-quick-start",
    "keywords": [
  "author": "GitHub",
  "license": "CC0-1.0",
  "devDependencies": {
    "electron": "~1.7.8",
    "electron-builder": "^19.45.4"

Packaging for operating systems

A distribution target (dist) needs to be added to the scripts: stanza to create package builds for Linux, Windows, and Mac.

  "scripts": {
    "start": "electron .",
    "dist": "build"

Adding a snap package

The distribution target is then made to start the snap build. The appId must be set, but is not used on Linux. Refer to the Electron Builder documentation for an appropriate value if you are also building for Windows and Mac.

  "build": {
    "appId": "io.snapcraft.quick-start",
    "linux": {
      "target": ["snap"]

Building the snap

You’ll first need to install snap support, and then install the snapcraft tool:

sudo snap install snapcraft --classic

To build Electron applications you also need Node installed, which can be downloaded from NodeSource.

If you have just installed snap support, start a new shell so your PATH is updated to include /snap/bin. You can then build this example yourself:

git clone https://github.com/snapcraft-docs/electron-quick-start
cd electron-quick-start
npm install
npm run dist

The resulting snap can be installed locally. This requires the --dangerous flag because the snap is not signed by the Snap Store. The --devmode flag acknowledges that you are installing an unconfined application:

sudo snap install dist/electron-quick-start_1.0.0_amd64.snap --dangerous --devmode

You can then try it out:


Removing the snap is simple too:

sudo snap remove electron-quick-start

Share with your friends

To share your snaps you need to publish them in the Snap Store. First, create an account on dashboard.snapcraft.io. Here you can customize how your snaps are presented, review your uploads and control publishing.

You’ll need to choose a unique “developer namespace” as part of the account creation process. This name will be visible by users and associated with your published snaps.

Make sure the snapcraft command is authenticated using the email address attached to your Snap Store account:

snapcraft login

Reserve a name for your snap

You can publish your own version of a snap, provided you do so under a name you have rights to. You can register a name on dashboard.snapcraft.io, or by running the following command:

snapcraft register myelectronsnap

Be sure to update the name: in your package.json to match this registered name, then run npm dist again.

Upload your snap

Use snapcraft to push the snap to the Snap Store.

snapcraft push --release=edge myelectronsnap_*.snap

Running npm dist creates a snapcraft.yaml file in the root of your project. If you’re happy with your snap, you can commit this file to your GitHub repo and turn on automatic builds so any further commits automatically get released to edge, without requiring you to manually build locally.
