fabric8-ui

Build Status codecov

Development environment

Run fabric8-ui with remote backends

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 openshift.io production cluster:

source environments/openshift-prod-cluster.sh

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/local-cluster.sh

NOTE: If you want to target a local WIT backend, check our wiki How To pages.

Build and Run

Requires node version 8.3.0 and npm 5.3.0. Consider using Node Version Manager.

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

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

Run test

We use jest test loader because it's faster than karma execution.

All tests

npm run test

Note: the first execution of the test take longer, subsequent calls are cached and much faster.

Watch mode

If you want to run all test in a feature-flag folder in watch mode:

npm run test -- feature-flag -- --watch=true

Note: You don't need to specify full path for the name of the test.

Debug

npm run test:debug

or to debug a specific test:

npm run test:debug -- feature-flag.service
  • Go to chrome: chrome://inspect
  • Let go the debugger and put debugger in your test.

To debug in your prefer IDE consolt Jest debugging documentation.

VS Code

Run ext install EditorConfig to read the .editorconfig file

Feature flag

HTML, CSS and Less

| Code Guidelines

fabric8-ui uses HTML5 elements where appropriate, and practices practicality over purity. Use the least amount of markup with the fewest intricacies as possible.

Attribution order, syntax definitions and declaration order are an important aspect of the fabric8-ui code and should be followed according the the guidelines.

fabric8-ui uses Less for it's stylesheets. If you find yourself wanting to create a shared style that multiple components will use, then we recommend adding it to an existing .less file in the src/assets/stylesheets/shared/ directory. Only update these styles if you are making a truly global style, and are going to synchronize your changes across all of the various UI projects.

If you only want to make a change to a specific component, do so in that component's .less file, according to Angular best practices.

The file osio.less is imported into every component Less file using @import (reference), so all files inside of the /shared directory will be used by each component.

Code Quality

fabric8-ui utilizes stylelint and htmlhint to check the less and html code. As part of each linter, we include three files: .stylelintrc, .stylelintignore and .htmlhintrc.

The .stylelintrc configuration file controls our configuration for the stylelinter, which only checks folders and files that are not included in the .stylelintignore file. This allows us to exclude certain areas of the application, as needed.

The .htmlhintrc configuration file controls our HTML verification configuration. In the creation of this configuration, we have taken into account the various Angular elements that will exist in the HTML pages.

Running the code quality checks

Each linter is built into the build process, so running npm run build or npm start will display any errors, their location (file name and line number), and any error message(s). Whenever a file that is watched by the code quality checks is changed, the build (if started with npm start) will re-run, checking only the altered files.

If you would like to run either of these checks individually, without kicking off a full build, you can do so by installing stylelint and htmlhint globally:

npm install stylelint -g
npm install htmlhint -g

After installing stylelint and htmlhint globally, you can run the following commands:

  • stylelint "**/*.less"

This will run stylelint against all .less files in fabric8-ui/src, using the .stylelintrc configuration file.

  • htmlhint

This will run htmlhint against all html files in fabric8-ui/src, using the .htmlhintrc configuration file. This command will not ignore the files and folders dictated in the webpack.common.js file, leading to the possibility of errors being displayed that will not appear at build time.

Alternatively, if you would like to check a subset of folders, or a specific file, you can do so by altering your htmlhint command:

  cat src/app/layout/header/header.component.html | htmlhint stdin

Integrations

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.

Context

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

Notifications

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.

Working with multi-level depenendencies

Let's consider a scenario wher you have an NPM module 'C' which sits inside another NPM module 'B' which is included in the parent module 'A'. During development, it is very common to use npm link to create a symlink and test the changes automatically. In this case, there is a high possbility for the parent module 'A' to be totally unaware of the existence of npm module 'C' as the symlinks don't get propagated all the way up. As a result, you might end up seeing the following error in the parent module 'A':

Module not found: Error: Can't resolve 'C' in ...

To address this, we can make the parent module 'A' be aware of the existence of 'C', by making changes in

tsconfig.json

of the parent module 'A'.

Inside "compilerOptions", Add an object key, "baseUrl" which basically identifies the base of the project and all the other urls are relative to this. Add an object key, "paths" as below

{
  "compilerOptions": {
    .
    .
    .
    "baseUrl": ".",
    "paths": {
      .
      .
      .
      "C": ["node_modules/B/node_modules/C"] //relative to the base url
    }
  }
}

By doing this, parent module A now is aware of the existence of the grand child 'C'. This can be modified for n-level dependencies. If your project builds using AOT or in other words if your project uses tsconfig-aot.json or similar, same things can be handled over there as well.

Continuous Delivery & Semantic Releases

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 npmjs.com and a release tag created on GitHub. The version will be updated following semantic versioning 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>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>

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.

Revert

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.

Type

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.

Scope

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

Subject

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

Body

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.

Footer

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 https://github.com/angular/angular.js/blob/master/CONTRIBUTING.md#commit

Examples

Appears under "Features" header, pencil sub-header:

feat(pencil): add 'graphiteWidth' option

Appears under "Bug Fixes" header, graphite sub-header, 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.

Commitizen - craft valid commit messages

Commitizen helps you craft correct commit messages. Install it using npm install commitizen -g. Then run git cz rather than git commit.

Running End-to-End (E2E) Tests

A set of E2E tests have been written to verify the operation of major features such as the creation of a build pipeline.

These E2E tests are configured to be run locally in a shell, locally in a docker container, and in a docker container in Centos CI. The tests can be run against a local or remote server by specifying the server's URL as a parameter to the tests.

The E2E tests are available in this repo: https://github.com/fabric8io/fabric8-test

The full set of instructions on installing and executing the E2E tests are avalable here: https://github.com/fabric8io/fabric8-test/blob/master/ee_tests/README.md

Easy E2E Test Setup

Run the following script and follow the on screen prompts to configure the test environment. The process will checkout the fabric8-test project as a sibling to fabric8-ui.

npm run e2e

To clean up the fabric8-test project:

npm run e2e:clean

To delete the e2e configuration file and re-prompt for all data:

npm run e2e:reconfig

To run the e2e tests using the last configuration without prompting:

npm run e2e:last

Mac Users

You may encounter the error readlink: illegal option -- f. To fix this, run the following commands:

brew install coreutils
ln -s "$(which greadlink)" "$(dirname "$(which greadlink)")/readlink"

Monorepo

This monorepo is managed with Lerna.

To get started, install the project dependencies and bootstrap all packages. The bootstrap process will update all packages with all their dependencies and link any cross-dependencies.

npm install
npm run bootstrap

fabric8-planner's Issues

Rename all the selectors in components as the class name.

  • Two component class having same selector would throw an error. To be on safe side, we should always name the selectors as the class name, that way the chances of such conflict will be minimized.
  • Also instead of using declarations at app.module.ts we can use directives in main components to include sub components. That will also help us to minimize the chances of conflict.

The error this problem produces, doesn't have any meaningful message. So, we need to be careful. This looks like a design problem of Angular2. I hope we never run across with a conflict between a selector from global module and local module. I couldn't find a proper solution yet, please post here if anyone can.

Seamless integration of Patternfly/js Components in UI

We have to find a way to use the Patternfly/Bootstrap JS code in UI. Many widgets we plan to use are utilizing this code (ex. also "basic stuff" like opening/closing dropdowns). At the same time, we have to make sure the code works nicely with Angular 2 and our implementation of it.

Support for HTML5 (History API) pushState in the backend

For now I have send a pull request (#41) to disable history API and use hash based routing.

But for a better URL navigation, we need to support History API.

Ref: https://developer.mozilla.org/en-US/docs/Web/API/History_API#The_pushState()_method

The index.html should be the default target for all request in the web app. We need a custom Nginx configuration to support this.

Ref. http://stackoverflow.com/questions/13812550/configuring-nginx-for-single-page-website-with-html5-push-state-urls

BTW, if we are going to implement #44 , I think the configuration will become much saner.

Unify what deps should be used in package.json

Right now, various dependencies and dev dependencies are specified using both exact version and using caret:

"karma-mocha": "1.0.1",
"karma-phantomjs-launcher": "^1.0.0",
"karma-sourcemap-loader": "^0.3.7",
"karma-webpack": "1.7.0",

There are two ways how to unify that:

  1. use only specific version (e.g. 1.0.1), this approach is easier but requires more commits for deps upgrading
  2. use only caret prefix (e.g. ^1.0.1), this way some deps will be auto-updated, downside is that people might use different versions during development and build is not reproducible after some time, this approach should be coupled with using shrinkwrapping (https://docs.npmjs.com/cli/shrinkwrap)

Add i18n support

Tod said at the Bangalore meeting, that the UI should have i18n support in place, even if we only support one language (English) for the forseeable time. We need to evaluate i18n solutions, choose one and integrate it in our project.

Implement unique id values for UI elements, to facilitate easier UI test automation

In building a (very) basic POC UI automation test (see: #17) I noticed that the UI elements are not defined with unique IDs. as a result, the POC test relies on brittle xPath data to locate UI elements. For example:

public SelenideElement saveButton() {
return $(byXpath("//my-app/work-item-list/div/div/work-item-detail/div/button[2]"));
}

Having unique IDs for elements would make the test automation much easier and the tests more maintainable. Thanks!

docker-compose up fails

Unfiy the developer and production configs

There should'nt be a seperate config set for development v/s production configs and machine setup - most of the content needed in developer only stages should be abstracted out into either a run time config or collected from defaults at build time.

site specific content should be stripped out in a way that the CI infra, the pre-prod infra, the prod infra and the developer environ can influence them opportunisitically.

Can we add id's to a workite,'s view and delete buttons?

Having the id's added to the workitem lists (http://localhost:8088/#/work-item-list) is a big help - thx!

Can we also add id's for the individual details and delete buttons? It;s not difficult to access the buttons relative to their parent's id's:

workItemList_ViewItemDetailBtn = .//[@id='workItemList_OuterWrap_0']/div/div[1]/button[1]
workItemList_deleteListItemBtn = .//
[@id='workItemList_OuterWrap_0']/div/div[1]/button[2]

But - it would be much easier to access the buttons could be accessed directly through their id's - for example, by embedding the parent's id digit in the button id. Thx!

View Details Delete

Can not update work item state from the list twice or more without refreshing.

What -

  • Open the work item list.
  • Open developer console to see the network requests.
  • Click on the work item state.
  • Change it to another.
  • Goes through.
  • Now again click on the state of the same work item.
  • Try changing it to something else.
  • It fails with a 500.

Fix -

  • On the first change we are not updating the version of the work item.
  • Therefore the failure response returns a version conflict error.

Mobile (Phone) First - List View

As a user, I want to be able to view the items in my list on my mobile (phone type TBD) device, so that I can see all the issues that exist, for the MVP, while away from my laptop. This view will need to progressively scale up to a tablet and then desktop device (separate stories to follow).

InVision Prototype:

Use Observables instead of Promises to fetch cards

Hi,

I was trying to connect to the UI to the core using the core's REST API endpoint. That is when I stumpled over the CardService.getCards() method which returns a Promise<Card[]>. There seem to be quite some disadvantages when using a Promise compare to an Observable.

Consider these points (taken from here):

  1. Don’t hit the search endpoint on every key stroke.
    Treat the search endpoint as if you pay for it on a per-request basis. No matter if it’s your own hardware or not. We shouldn’t be hammering the search endpoint more often than needed. Basically we only want to hit it once the user has stopped typing instead of with every keystroke.
  2. Don’t hit the search endpoint with the same query params for subsequent requests.
    Consider you type foo, stop, type another o, followed by an immediate backspace and rest back at foo. That should be just one request with the term foo and not two even if we technically stopped twice after we had foo in the search box.
  3. Deal with out-of-order responses.
    When we have multiple requests in-flight at the same time we must account for cases where they come back in unexpected order. Consider we first typed computer, stop, a request goes out, we type car, stop, a request goes out. Now we have two requests in-flight. Unfortunately the request that carries the results for computer comes back after the request that carries the results for car. This may happen because they are served by different servers. If we don’t deal with such cases properly we may end up showing results for computer whereas the search box reads car.

This 7 minute video gives a nice overview of why wants to use Observables over Promises: https://egghead.io/lessons/rxjs-rxjs-observables-vs-promises

I understand that his requires some changes to how card objects get filtered and passed around.

URL is part of UX

There is no consistency in the URL design in the router. These are the URL end points in the code: login, work-item-list, board, quick-add/:id, detail/:id

For some inspiration of URL design, look at Github issue tracker where this issue is reported.

Create a link between WorkItems

We need some way to visually link in a parent / child way workitems.

Experience 1603E131
A user with appropriate privileges obtains a definition file (for example via a web interface or a command line), edits the definition file which describes a work item link type between two work item types, and, associates it with the project (for example by uploading it via a web browser or using the command line). A default definition file is provided out of the box, and can be modified via this process.. Each link type must describe both the forward and reverse relationship (e.g. Parent/Child, Successor/Predecessor, Tested By/Tests, etc.) and also must also be one of four topologies: Network (undirected; circular relationships possible); Directed Network (directed; circular relationships possible); Dependency (directed; circular relationships prohibited); Tree (directed; circular relationships prohibited; one-to-many).

-- this is not end-user functionality for Pizza the Hutt.

Deployment acceptance criteria should be testable

We need a base set of acceptance tests to run against the app for use in the build, release process.

These tests would run after the app is built and pushed into the relevant pod, as a way to verify that the app is now promoteable to productoin loads.

Write tests

We should test the code, ideally via unit tests at build time, and some integration tests to validate the api version matching /expected in the build, and finally deployment acceptance tests.

Rendering problems on mobile devices (iPad, Nexus 5, and iPhone5)

I noticed some odd renderings on mobile devices:

Sometimes the list view items overlap each other, sometimes space is wasted and sometimes the quick add form items are stacked vertically instead of horizontally.

I now, that we're in an early stage but I just wanted to guys let you know this.

Use of nodejs 6 when rhel/centos only have nodejs4

how do we handle that nodejs is not available on rhel in the version we use ?

This issue is just to track what we know about the situation - not to say we have use nodejs4, we got options.

@kbsingh did you have some context/info on what exactly is available ?

@joshuawilson is nodejs 6 a hard requirement ?

Check npm dependencies for build warnings

Currently, the build outputs some warnings that should be examined:

npm WARN deprecated [email protected]: cross-spawn no longer requires a build toolchain, use it instead!
npm WARN deprecated [email protected]: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated [email protected]: to-iso-string has been deprecated, use @segment/to-iso-string instead.
npm WARN deprecated [email protected]: Jade has been renamed to pug, please install the latest version of pug instead of jade
npm WARN deprecated [email protected]: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
