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

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

Browser 'Environment' Variables

In order to configure different configurations of Consul you can use Web Inspector in your browser to set various cookie which to emulate different configurations whislt using the mock API.

For example: to enable ACLs, use Web Inspector to set a cookie as follows:

CONSUL_ACLS_ENABLE=1

This will enable the ACLs login page, to which you can login with any ACL token/secret.

Variable	Default Value	Description
CONSUL_ACLS_ENABLE	false	Enable/disable ACLs support.
CONSUL_ACLS_LEGACY	false	Enable/disable legacy ACLs support.
CONSUL_NSPACES_ENABLE	false	Enable/disable Namespace support.
CONSUL_SSO_ENABLE	false	Enable/disable SSO support.
CONSUL_OIDC_PROVIDER_URL	undefined	Provide a OIDC provider URL for SSO.
CONSUL_LATENCY	0	Add a latency to network requests (milliseconds)
CONSUL_METRICS_POLL_INTERVAL	10000	Change the interval between requests to the metrics provider (milliseconds)
CONSUL_METRICS_PROXY_ENABLE	false	Enable/disable the metrics proxy
CONSUL_METRICS_PROVIDER		Set the metrics provider to use for the Topology Tab
CONSUL_SERVICE_DASHBOARD_URL		Set the template URL to use for Service Dashboard links
CONSUL_UI_CONFIG		Set the entire ui_config for the UI as JSON if you don't want to use the above singular variables
CONSUL_SERVICE_COUNT	(random)	Configure the number of services that the API returns.
CONSUL_NODE_COUNT	(random)	Configure the number of nodes that the API returns.
CONSUL_KV_COUNT	(random)	Configure the number of KV entires that the API returns.
CONSUL_INTENTION_COUNT	(random)	Configure the number of intentions that the API returns.
CONSUL_POLICY_COUNT	(random)	Configure the number of policies that the API returns.
CONSUL_ROLE_COUNT	(random)	Configure the number of roles that the API returns.
CONSUL_NSPACE_COUNT	(random)	Configure the number of namespaces that the API returns.
CONSUL_UPSTREAM_COUNT	(random)	Configure the number of upstreams that the API returns.
CONSUL_EXPOSED_COUNT	(random)	Configure the number of exposed paths that the API returns.
CONSUL_CHECK_COUNT	(random)	Configure the number of health checks that the API returns.
CONSUL_OIDC_PROVIDER_COUNT	(random)	Configure the number of OIDC providers that the API returns.
DEBUG_ROUTES_ENDPOINT	undefined	When using the window.Routes() debug utility (see utility functions), use a URL to pass the route DSL to. %s in the URL will be replaced with the route DSL - http://url.com?routes=%s

See ./mock-api for more details.

Browser 'Debug Utility' Functions

We currently have one 'debug utility', that only exists during development (they are removed from the production build using Embers runInDebug). You can call these either straight from the console in WebInspector, or by using javascript URLs i.e. javascript:Routes()

Variable	Arguments	Description
Routes(url)	url: The url to pass the DSL to, if left undefined just use a blank tab	Provides a way to easily print out Embers Route DSL for the application or to pass it straight to any third party utility such as ember-diagonal
Scenario(str)	str: 'Cookie formatted' string, if left undefined open a new tab with a link/bookmarklet to the current Scenario	Provides a way to easily save and reload scenarios of configurations via URLs or bookmarklets

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)

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

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

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.
