Before you start: Pointing to a cluster

You need to setup your shell to point to the right cluster so that it can talk to the required back end services like KeyCloak, WIT, Forge, OpenShift etc.

We provide various sample environments out of the box which make it easier to get started. They are all located as bash scripts in environments.

The default one you should use when you want to develop on the console is to reuse production cluster:

source environments/

There are others too. For example if you want to try run fabric8 locally on minishift and connect fabric8-ui to it then try:

source environments/

VS Code

  • Run ext install EditorConfig to read the .editorconfig file

Get dependencies

Run npm install. This will download all the required dependencies to be able to start the UI.

To start

Run npm start. This will start the UI with livereload enabled. Then navigate to http://localhost:3000.

CSS and Less

fabric8-ui uses Less for it's stylesheets. It also uses the Angular emulation of the shadow dom, so you will normally want to place your styles in the .component.less file next to the html and the typescript. We write our styles according to our Code Guidelines.

If you find yourself wanting to create a shared style that multiple components will use, then we recommend adding it as a mixin to src/assets/stylesheets/_shared-mixins.less. The mixins are imported in to every .component.less file. You can then create a real class by doing something like

.my-class {
  @include my-class;

The src/assets/stylesheets/ directory includes a shared directory. These are shared global styles that we will refactor out in to a shared library at some point. Only update these styles if you are making a truly global style, and are going to synchronise your changes across all the various UI projects.


fabric8-ui uses rxjs to provide loose coupling between modules (both those in the code base and those integrated via NPM). To do this, fabric8-ui makes extensive use of the Broadcaster.


Space changed

When the current space the user is viewing changes, fabric8-ui broadcasts with the key spaceChanged and the
new Space as the payload.

UI integrations


To send a notification to the user, the module should import ngx-fabric8-wit and inject the Notifications service, and call the message() method, passing in a Notification. You can subscribe to the result of message() to observe any NotificationActions that result from the notification.

Continuous Delivery & Semantic Relases

In ngx-fabric8-wit we use the semantic-release plugin. That means that all you have to do is use the AngularJS Commit Message Conventions (documented below). Once the PR is merged, a new release will be automatically published to and a release tag created on github. The version will be updated following semantic versionning rules.

Commit Message Format

A commit message consists of a header, body and footer. The header has a type, scope and subject:

<type>(<scope>): <subject>

The header is mandatory and the scope of the header is optional.

Any line of the commit message cannot be longer 100 characters! This allows the message to be easier to read on GitHub as well as in various git tools.


If the commit reverts a previous commit, it should begin with revert:, followed by the header of the reverted commit. In the body it should say: This reverts commit <hash>., where the hash is the SHA of the commit being reverted.


If the prefix is fix, feat, or perf, it will always appear in the changelog.

Other prefixes are up to your discretion. Suggested prefixes are docs, chore, style, refactor, and test for non-changelog related tasks.


The scope could be anything specifying place of the commit change. For example $location, $browser, $compile, $rootScope, ngHref, ngClick, ngView, etc...


The subject contains succinct description of the change:

  • use the imperative, present tense: "change" not "changed" nor "changes"
  • don't capitalize first letter
  • no dot (.) at the end


Just as in the subject, use the imperative, present tense: "change" not "changed" nor "changes". The body should include the motivation for the change and contrast this with previous behavior.


The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit Closes.

Breaking Changes should start with the word BREAKING CHANGE: with a space or two newlines. The rest of the commit message is then used for this.

A detailed explanation can be found in this document.

Based on


Appears under "Features" header, pencil subheader:

feat(pencil): add 'graphiteWidth' option

Appears under "Bug Fixes" header, graphite subheader, with a link to issue #28:

fix(graphite): stop graphite breaking when width < 0.1

Closes #28

Appears under "Performance Improvements" header, and under "Breaking Changes" with the breaking change explanation:

perf(pencil): remove graphiteWidth option

BREAKING CHANGE: The graphiteWidth option has been removed. The default graphite width of 10mm is always used for performance reason.

The following commit and commit 667ecc1 do not appear in the changelog if they are under the same release. If not, the revert commit appears under the "Reverts" header.

revert: feat(pencil): add 'graphiteWidth' option

This reverts commit 667ecc1654a317a13331b17617d973392f415f02.
