Building the snap on Linux

[evan]

NOTE TO EDITORS

This topic contributes to a new set of snap documentation. See Proposed new documentation outline for further details.

Now that you have a snapcraft.yaml describing how to assemble your app and dependencies, you can build a snap.

First, install snap support by following the appropriate guide for your distribution. Next, install snapcraft, the command-line tool for building snaps:

sudo snap install snapcraft --classic

Return to the root directory of the project containing your snapcraft.yaml and run snapcraft:

snapcraft

ⓘ If you are working with an Electron app, you will use the snapcraft tool for publishing to the Snap Store but not for building your snap. Electron apps do not have a snapcraft.yaml file.

Follow this guide to build a snap of an Electron app using electron-builder.

If the snap build completes successfully, you will find a .snap file in the same directory that you ran the snapcraft command. You can inspect its contents to ensure it contains all of your application’s assets:

unsquashfs -l *.snap

Next steps

Continue on to learn how to install, test, and publish your snap file.
