nutrifyi-embed

Embed NutriFYI widgets — foods, glossary terms, interactive tools, and inline elements — on any website. 9 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 NutriFYI database.

Every widget includes a "Powered by NutriFYI" backlink and a medical disclaimer directing readers to consult healthcare professionals.

Quick Start

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

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

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

Widget Types

| Type | Usage | Description | |------|-------|-------------| | entity | <div data-nutrifyi="entity" data-slug="..."></div> | Entity detail card | | glossary | <div data-nutrifyi="glossary" data-slug="..."></div> | Glossary term definition | | guide | <div data-nutrifyi="guide" data-slug="..."></div> | Guide summary card | | search | <div data-nutrifyi="search" data-slug="..."></div> | Search box | | compare | <div data-nutrifyi="compare" data-slug="..."></div> | Side-by-side comparison | | faq | <div data-nutrifyi="faq" data-slug="..."></div> | FAQ accordion | | bmi-calculator | <div data-nutrifyi="bmi-calculator" data-slug="..."></div> | Interactive BMI calculator — fully offline | | nutrition-label | <div data-nutrifyi="nutrition-label" data-slug="..."></div> | USDA-style nutrition facts label | | macro-badge | <div data-nutrifyi="macro-badge" data-slug="..."></div> | Inline macronutrient badge |

Widget Options

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

Themes

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

<!-- Dark -->
<div data-nutrifyi="entity" data-slug="foods" data-theme="dark"></div>

<!-- Sepia -->
<div data-nutrifyi="entity" data-slug="foods" data-theme="sepia"></div>

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

Styles

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

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

Web Components (Custom Elements)

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

<!-- Custom element form -->
<nutrifyi-entity slug="foods" theme="light"></nutrifyi-entity>
<nutrifyi-compare slugs="foods,other-slug"></nutrifyi-compare>
<nutrifyi-search placeholder="Search Foods..."></nutrifyi-search>

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

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

CDN Options

jsDelivr (recommended — global CDN, auto-updates with npm)

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

Specific version (production stability)
