Lagoon UI

The main user interface and dashboard for Lagoon.

Build

To build and test changes locally the Lagoon UI can be built via Yarn or Docker.

Testing locally, the UI can be connected to production or development Lagoon instances. Here we have included the URLs for the amazee.io cloud, but you can substitute your own.

Yarn

Note: Within docker-compose.yml GRAPHQL_API & KEYCLOAK_API are set to localhost by default.

yarn install
yarn build && GRAPHQL_API=https://api.lagoon.amazeeio.cloud/graphql KEYCLOAK_API=https://keycloak.amazeeio.cloud/auth yarn dev

These values can also be updated in docker-compose.yml.

Docker

Note: Within docker-compose.yml GRAPHQL_API & KEYCLOAK_API will need to be set to

  GRAPHQL_API: "${GRAPHQL_API:-https://api.lagoon.amazeeio.cloud/graphql}"
  KEYCLOAK_API: "${KEYCLOAK_API:-https://keycloak.amazeeio.cloud/auth}"

docker-compose build
docker-compose up -d

This project is tested with BrowserStack.

Linting

The linter is configured for both JS and TypeScript files, with the latter being much stricter. It runs during the build step but can also be ran during development by yarn lint

Linter and TS configs are both located in the root of the project as .eslintrc.js and tsconfig.json

Testing

Lagoon UI uses cypress for e2e tests.

A couple of environment variables are required:

• email - keycloak user
• password - keycloak password
• keycloak - Keycloak url (used for cypress sessions)
• api - GraphQL api endpoint
• url - running UI instance url
• user_guest - user with guest role
• user_reporter - user with reporter role
• user_developer - user with developer role
• user_maintainer - user with maintainer role
• user_owner - user with owner role
• user_orguser - Organization user
• user_orgviewer - Organization viewer
• user_orgowner - Organization owner
• user_platformowner - Platform owner

These environment variables can either be inlined or saved in Cypress.config.ts file:

import { defineConfig } from 'cypress'

export default defineConfig({
  env: {
    foo: 'bar',
    CYPRESS_CY_EMAIL: ...
    ...
  },
})

To open cypress in a browser:

npx cypress open

To run cypress tests in headless mode:

npx cypress run

Styling

Lagoon-UI uses styled-components and it's recommended to use separete files for styling for each component. <style jsx> tags are allowed but nesting is not.

Plugin system

The Lagoon UI supports basic plugins via a plugin registry. The file, in the root, "plugins.json" allows you to hook into the server side rendering to add additional CSS and Javascript files. These are simply added as "script" and "link" elements to the resulting HTML. We currently support adding elements to the head at at the end of the body as demonstrated below.

In this example, we load two elements, a JS script and a css file into the head, and then we add an external library at the bottom of the body.

{
    "head": [
        {"type": "script", "location":"/static/custom.js"},
        {"type": "link",   "href":"/static/plugins/custom.css"}

    ],
    "body": [
        {"type": "script", "location":"https://www.cornify.com/js/cornify.js"}
    ]
}

Tours configuration

The tour.json file contains configuration for the tour of the Lagoon app. it has the following structure:

{
    "mode": "direct",
    "routes": [
        {
            "pathName": "/projects",
            "steps": [
                {
                    "target":".someclass",
                    "title:": "title of the tour step",
                    "content": "description of the tour step",
                }
                ...
            ]
        }
        ...
    ]
}

Note: The sequence of routes is self paced, meaning the users see information once as they traverse the app in an explanatory way

Tour steps use content hashes as keys, so if content or title changes, or a new step is added, the tour will automatically show it to the user.

Make sure to run this command after updating the tour.json step contents.

yarn run generateTourHash

Tour properties

• mode (string) - "translated" or "direct", if the value is "translated", content and title will be used as keys for lookup in the translation file, otherwise directly used.
• routes (array) - Array of objects, each describing a steps in the tour per route.
  • pathName (string) - route.
  • target (string) - css selector for the tour step.
  • content (string) - This property is used based on the mode property, acts as the tour step body.
  • title (string) - Similar to content, only acts as the header for the tour step.
  • key (string) - identifier of steps per route, needs to be unique for each object in the steps array, generated by running yarn run generateTourHash.
  • placement (string) (optional) - tooltip placement defined in react-joyride docs
