This gist is to accompany a more wordy blog post which covers everything in much more detail. These are the easily copy/pastable steps.
For this you will need:-
| name: gotop | |
| base: core18 # the base snap is the execution environment for this snap | |
| version: '0.1' # just for humans, typically '1.2+git' or '1.3.2' | |
| summary: gotop | |
| description: | | |
| A terminal based graphical activity monitor inspired by gtop and vtop | |
| grade: stable # must be 'stable' to release into candidate/stable channels | |
| confinement: strict # use 'strict' once you have the right plugs and slots |
We have identified a number of electron-based desktop applications which already have builds for Linux, but are not yet easily available in Ubuntu. The goal of this task it to select one of those applications and update the build system to add snap support.
Many of these applications require a newer version of node/npm to build than is available in Ubuntu. We recommend using Ubuntu 16.04 machine, virtual machine or container. Please do not do this task on a 17.10 system, but use 16.04.
In that 16.04 system, install node/npm from upstream nodesource as detailed at https://github.com/nodesource/distributions#debinstall
You may also want to go through the electron guide, to ensure your system is configured correctly to build electron applications successfully. https://docs.snapcraft.io/build-snaps/electron
