Prerequisites

You will need the following things properly installed on your computer.

• Git

• Node.js (with npm)

• yarn

• Ember CLI

• Google Chrome

Installation

• git clone https://github.com/hashicorp/consul.git this repository
• cd ui/packages/consul-ui

then:

To run the UI

From within ui/packages/consul-ui directory run:

• make start

To run tests

From within ui/packages/consul-ui directory run:

• make test-oss-view which will run the tests in Chrome

(see below and/or the testing section of the engineering docs for further detail)

Yarn Commands

Most used tooling scripts below primarily use make which will yarn install and in turn call node package scripts.

List of available project commands. yarn run <command-name>

Command	Description
build:staging	Builds the UI in staging mode (ready for PR preview site).
build:ci	Builds the UI for CI.
build	Builds the UI for production.
lint	Runs all lint commands.
lint:hbs	Lints hbs template files.
lint:js	Lints js files.
format	Runs all auto-formatters.
format:js	Auto-formats js files using Prettier.
format:sass	Auto-formats scss files using Prettier.
start	Runs the development app on a local server using the mock API.
start:consul	Runs the development app local server using a real consul instance as the backend.
start:staging	Runs the staging app local server.
test	Runs the ember tests in a headless browser.
test:view	Runs the ember tests in a non-headless browser.
test:oss	Runs only the OSS ember tests in a headless browser.
test:oss:view	Runs only the OSS ember tests in a non-headless browser.
test:coverage:view	Runs only the test specified for coverage in a non-headless browser.
test:node	Runs tests that can't be run in ember using node.
doc:toc	Automatically generates a table of contents for this README file.

Running / Development

The source code comes with a small development mode that runs enough of the consul API as a set of mocks/fixtures to be able to run the UI without having to run consul.

• make start or yarn start to start the ember app
• Visit your app at http://localhost:4200.

You can also run the UI against a normal Consul installation.

• consul server -dev to start consul listening on http://localhost:8500
• make start-consul to start the ember app proxying to consul (this will respect the CONSUL_HTTP_ADDR environment variable to locate the Consul installation.
• Visit your app at http://localhost:4200.

Example:

CONSUL_HTTP_ADDR=http://10.0.0.1:8500 make start-consul

Environment Variables

See ./docs/index.mdx

Branching

We follow a ui/**/** branch naming pattern. This branch naming pattern allows front-end focused builds, such as FE tests, to run automatically in Pull Requests. Please note this only works if you are a member of the HashiCorp GitHub Org. If you are an external contributor these tests won't run and will instead be run by a member of our team during review.

Examples:

• ui/feature/add...
• ui/bugfix/fix...
• ui/enhancement/update...

Contributing/Engineering Documentation

We have an in-app (only during development) component storybook and documentation site which can be visited using the Eng Docs link in the top navigation of the UI. Alternatively all of these docs are also readable via GitHub's UI, so folks can use whatever works best for them.

Browser 'Debug Utility' Functions and 'Environment' Variables

Run make start then visit http://localhost:4200/ui/docs/bookmarklets for a list of debug/engineering utilities you can use to help development of the UI under certain scenarios.

Code Generators

Many classes used in the UI can be generated with ember generators, try ember help generate for more details

Running Tests

Tests use the mock api (see ./mock-api for details), the mock-api runs automatically during testing, you don't need to run anything separately from the below commands in order for the tests to use the mock-api.

• make test or yarn run test
• make test-view or yarn run test:view to view the tests running in Chrome

For more guidance on running tests, see the testing section of the engineering docs.

OSS only tests can also be run using:

• make test-oss or yarn run test:oss
• make test-oss-view or yarn run test:oss:view to view the tests running in Chrome

Linting

make lint currently runs linting on the majority of js files and hbs files (using ember-template-lint).

See .eslintrc.js and .eslintignore for specific configuration.

Building

• make build builds the UI for production usage (env=production)
• make build-ci builds the UI for CI/test usage (env=test)

Static files are built into ./dist

Running Tests in Parallel

You probably don't need to understand this if you are simply running some tests locally.

Alternatively, ember-exam can be used to split the tests across multiple browser instances for faster results. Most options are the same as ember test. To see a full list of options, run ember exam --help.

Note: The EMBER_EXAM_PARALLEL environment variable must be set to override the default parallel value of 1 browser instance in testem.js.

To quickly run the tests across 4 parallel browser instances:

make test-parallel

To run manually:

$ EMBER_EXAM_PARALLEL=true ./node_modules/.bin/ember exam --split <num> --parallel

More ways to split tests can be found in the ember-exam README.md.
