pid-component

The pid-component is an easy to use web component that can be used to display PIDs, DOIs, ORCiDs, RORs, and other identifiers in an intuitive way. It is designed to be embeddable in any website and has a small form-factor mode that reduces its height to that of a single line of text.

Description

PID Component

Build Node 22 Node 24 Node 25 codecov CodeQL

DOI npm version npm downloads License Storybook

The pid-component is an easily extensible web component that can be used to display PIDs, ORCiDs, and other identifiers in a user-friendly way. It is easily extensible to support other identifier types.

Framework wrappers are available for React, Vue, and Angular.

The pid-component dynamically renders a component based on the value of the value property. Depending on the value, it decides which component to render, what priority to give it, and what props to pass to it. It also renders itself recursively for all its children when unfolded. You can set the maximum depth of recursion with the level-of-subcomponents property. By default, it is set to 1, which means that it will only render the first level of children, but not their children. You can prohibit unfolding of the component by setting the current-level-of-subcomponents to the same value as the level-of-subcomponents property.

Example of a DOI component with a nested ORCID component

Via CDN (no bundler)

You can load the component directly from unpkg with a single script tag:


<script type="module"
        src="https://unpkg.com/@kit-data-manager/pid-component/dist/pid-component/pid-component.esm.js"></script>

<pid-component value="21.T11981/be908bd1-e049-4d35-975e-8e27d40117e6"></pid-component>

Via npm

npm install @kit-data-manager/pid-component

Then use the component in your HTML:


<pid-component value="21.T11981/be908bd1-e049-4d35-975e-8e27d40117e6"></pid-component>

You can try this web component in the demo.

Only use the pid-component component! All the others are only for internal use and may change at any moment...

There are detailed docs for the pid-component component available in the Storybook and in the source code.

Please notice that you must use the hyphenated version of an attribute when using the component directly in HTML ( e.g. currentLevelOfSubcomponents -> current-level-of-subcomponents). When using inside Stencil or with JSX/TSX syntax, you must use the camelCase version.

Supported Types

The component automatically detects and renders the following types:

  • Dates: Formatted date strings.
  • ORCiDs: Resolvable via orcid.org. Displays profile information, affiliations, works, etc.
  • DOIs: With DataCite or CrossRef metadata; resolvable via doi.org. Supports various citation styles.
  • PIDs: Resolvable via handle.net.
  • RORs: Resolvable via ror.org. Displays organization details, hierarchies, and location.
  • SPDX: License identifiers and URLs.
  • ISBNs: International Standard Book Numbers (ISBN-10 and ISBN-13).
  • Email-addresses: Individual or comma-separated lists.
  • URLs: Starting with http:// or https://.
  • Locales: e.g., en-US, de-DE. Visualized with flags (if region is present).
  • JSON objects: Rendered with syntax highlighting and tree view using json-viewer.
  • Fallback: Everything else is rendered as a simple string.

Configuration & Settings

You can customize the behavior of specific renderers by passing a JSON configuration string to the settings property.

Available Settings

Global Settings

  • ttl (number): Time-to-live in milliseconds for cached data (default: varies by type).

DOIType

  • citationStyle (string): The citation style to use for the preview.
    • Options: APA, Chicago, IEEE, Harvard, Anglia Ruskin.
    • Default: APA.

ORCIDType

  • showAffiliation (boolean): Whether to show the affiliation in the summary.
    • Default: true.
  • affiliationAt (string/date as ms): The date for which the affiliation should be shown.
    • Default: Current date.

JSONType

  • darkMode (string): The theme for the JSON viewer.
    • Options: light, dark, system.
    • Default: system.

Example Configuration


<pid-component
  value="https://orcid.org/0000-0000-0000-0000"
  settings='[{"type":"ORCIDType","values":[{"name":"showAffiliation","value":false}]}]'
></pid-component>

Automatic PID Detection

The pid-component package includes an automatic PID detection feature that scans a DOM subtree for text containing PIDs and replaces them with interactive <pid-component> elements.

import { initPidDetection } from '@kit-data-manager/pid-component';

const controller = initPidDetection({
  root: document.getElementById('my-content'),
  darkMode: 'system',
  renderers: ['DOIType', 'ORCIDType', 'HandleType'],  // optional: try these first
  observe: true,   // watch for dynamic content changes
});

// Later:
controller.stop();     // pause MutationObserver
controller.rescan();   // re-scan the DOM
controller.destroy();  // remove all components, restore original text

Or with a plain <script> tag (no bundler):


<script type="module">
  import { initPidDetection } from 'https://unpkg.com/@kit-data-manager/pid-component/dist/esm/index.js';

  initPidDetection({
    root: document.getElementById('content'),
    darkMode: 'system',
  });
</script>

How It Works

  1. Walks the DOM tree collecting text nodes (skips <script>, <style>, <code>, <pre>, <pid-component>, etc.)
  2. Tokenizes text and sanitizes surrounding punctuation (dots, commas, quotes, brackets)
  3. Runs tokens through the detection registry (same regex patterns used by the renderers)
  4. Wraps only matched PID tokens in <pid-component> elements — non-matching text stays untouched
  5. Original text stays visible until the component finishes loading; on failure, original text is restored

Available Renderer Keys

DateType, ORCIDType, DOIType, HandleType, RORType, SPDXType, EmailType, URLType, LocaleType, JSONType, ISBNType, FallbackType

Framework Integration

  • React: Call in useEffect(), return controller.destroy() as cleanup
  • Angular: Call in ngAfterViewInit(), cleanup in ngOnDestroy()
  • Vue: Call in onMounted(), cleanup in onUnmounted()

See the Storybook documentation for detailed examples and interactive demos.

PID Resolver helper classes

The pid-component package exports a useful helper class for resolving PIDs. These are PID, PIDDataType and PIDRecord and can be imported like this:

import { PID, PIDDataType, PIDRecord } from "@kit-data-manager/pid-component"

const pid = new PID("21.T11981/be908bd1-e049-4d35-975e-8e27d40117e6")
const pidRecord = await pid.resolve()
const pidDataType = await PIDDataType.resolveDataType(pid)

Further documentation is available in the source code.
