@brightspace-ui-labs/ou-filter v2.2.2

d2l-labs-ou-filter

A Lit component that renders org unit structure tree. It supports load more and searching functionality.

Note: this is a "labs" component. While functional, these tasks are prerequisites to promotion to BrightspaceUI "official" status:

• Design organization buy-in
• Architectural sign-off
• Continuous integration
• Cross-browser testing
• Unit tests (if applicable)
• Accessibility tests
• Visual diff tests
• Localization with Serge (if applicable)
• Demo page
• README documentation

Usage

import { action, decorate, observable } from 'mobx';
import { MobxLitElement } from '@adobe/lit-mobx';
import { OuFilterDataManager } from '@brightspace-ui-labs/ou-filter/ou-filter.js';

class FooDataManager extends OuFilterDataManager {

	constructor() {
		super();
		this._orgUnitTree = new Tree({});
	}

	async loadData() {
		this._orgUnitTree = new Tree({ nodes: ..., ... });
	}
}

decorate(FooDataManager, {
	_orgUnitTree: observable,
	loadData: action
});

class FooPage extends MobxLitElement {
  constructor() {
    this.dataManager = new FooDataManager();
  }

  firstUpdated() {
    this.dataManager.loadData();
  }

  render () {
    return html`<d2l-labs-ou-filter
        .dataManager=${this.dataManager}
        select-all-ui
        @d2l-labs-ou-filter-change="${this._orgUnitFilterChange}"
      ></d2l-labs-ou-filter>`;
  }

  _orgUnitFilterChange() {
    console.log(event.target.selected);
  }
}

Visual Diff Testing

This repo uses the @brightspace-ui/visual-diff utility to compare current snapshots against a set of golden snapshots stored in source control.

The golden snapshots in source control must be updated by the visual-diff GitHub Action. If a pull request results in visual differences, a draft pull request with the new goldens will automatically be opened against its branch.

To run the tests locally to help troubleshoot or develop new tests, first install these dependencies:

npm install @brightspace-ui/visual-diff@X mocha@Y puppeteer@Z  --no-save

Replace X, Y and Z with the current versions the action is using.

Then run the tests:

# run visual-diff tests
npx mocha './test/**/*.visual-diff.js' -t 10000
# subset of visual-diff tests:
npx mocha './test/**/*.visual-diff.js' -t 10000 -g some-pattern
# update visual-diff goldens
npx mocha './test/**/*.visual-diff.js' -t 10000 --golden

Versioning and Releasing

This repo is configured to use semantic-release. Commits prefixed with fix: and feat: will trigger patch and minor releases when merged to main.

To learn how to create major releases and release from maintenance branches, refer to the semantic-release GitHub Action documentation.
