Mender is an open source over-the-air (OTA) software updater for embedded Linux devices. Mender comprises a client running at the embedded device, as well as a server that manages deployments across many devices.

This repository contains the Mender Graphical User Interface, which is part of the Mender server. The Mender server is designed as a microservices architecture and comprises several repositories.

The GUI exposes the entirety of Mender's functionality to the user, including deployment definition, scheduling and monitoring, device listing and admission, etc.

To start using Mender, we recommend that you begin with the Getting started section in the Mender documentation.

We welcome and ask for your contribution. If you would like to contribute to Mender, please read our guide on how to best get started contributing code or documentation.

In order to develop the GUI code to contribute, it is required to nodejs and npm installed, followed by an execution of npm install to install all the dependencies in package.json. Work on the files in 'src'. Running npm run watch will watch for your changes as you develop and build as you go. The watch command is intended to build however the content should be served from within the regular container running in your local mender setup. To connect the two a typical approach is to create a docker-compose.override.yml in the folder you have cloned the integration repo into (to isolate the changes made to the running environment in a single file) with the following content:

version: '2.1'
services:
    mender-gui:
        volumes:
            - ../<path-to-clone-of-the-gui-repo>/dist:/var/www/mender-gui/dist

and then start the demo environment with this file like this: ./demo -f docker-compose.override.yml up from the integration clone folder. The content should be accessible under https://localhost/ just as without any modifications. While running npm run watch the results of each incremental build should show up on page refresh. To ensure committed changes pass the CI pipeline it is good to run npm run lint and npm run test before you submit your changes for review.

The project is equipped with commit checks powered by husky that check for linter problems and run tests on the changed files. To also check your commit messages and fix potential problems with them, make sure to set MENDER_TESTING in your ENV to a local clone of the mendertesting repository.
