namefyi-embed

Embed NameFYI widgets — names, glossary terms, interactive tools, and inline elements — on any website. 10 widget types, zero dependencies, Shadow DOM style isolation, 4 built-in themes (light, dark, sepia, auto), 2 styles (modern, clean), and live data from the NameFYI database.

Every widget includes a "Powered by NameFYI" backlink directing readers to the full reference.

Quick Start

<!-- Place widget div where you want it to appear -->
<div data-namefyi="entity" data-slug="names" data-theme="light"></div>

<!-- Load the embed script once, anywhere on the page -->
<script src="https://cdn.jsdelivr.net/npm/namefyi-embed@1/dist/embed.min.js"></script>

That's it. The widget fetches data from the NameFYI API and renders with full style isolation.

Widget Options

| Attribute | Values | Default | Description | |-----------|--------|---------|-------------| | data-namefyi | entity, compare, glossary, guide, search, faq, [tools] | required | Widget type | | data-slug | e.g. "names" | — | Entity slug from the NameFYI database | | data-theme | light, dark, sepia, auto | light | Visual theme (auto follows OS preference) | | data-style | modern, clean | modern | Widget design style | | data-size | default, compact, large | default | Widget size | | data-placeholder | any string | "Search Names..." | Search box placeholder |

Themes

<!-- Light (default) -->
<div data-namefyi="entity" data-slug="names" data-theme="light"></div>

<!-- Dark -->
<div data-namefyi="entity" data-slug="names" data-theme="dark"></div>

<!-- Sepia -->
<div data-namefyi="entity" data-slug="names" data-theme="sepia"></div>

<!-- Auto — follows OS dark/light preference -->
<div data-namefyi="entity" data-slug="names" data-theme="auto"></div>

Styles

<!-- Modern (default) — clean lines, rounded corners, accent gradients -->
<div data-namefyi="entity" data-slug="names" data-style="modern"></div>

<!-- Clean — minimal borders, utility-focused, data-first aesthetic -->
<div data-namefyi="entity" data-slug="names" data-style="clean"></div>

Web Components (Custom Elements)

As an alternative to data-* attributes, you can use native HTML custom elements:

<!-- Custom element form -->
<namefyi-entity slug="names" theme="light"></namefyi-entity>
<namefyi-compare slugs="names,other-slug"></namefyi-compare>
<namefyi-search placeholder="Search Names..."></namefyi-search>

<script src="https://cdn.jsdelivr.net/npm/namefyi-embed@1/dist/embed.min.js"></script>

Use style-variant (not style) to avoid conflicts with the HTML reserved style attribute.
