### Jinja Macro Rules (app/templates/**/*.html)
#### MAC-001: Use Shared Macros for Repeated Patterns
**Severity:** Error
Never copy-paste HTML patterns. Use or create shared macros in `app/templates/shared/macros/`.
```jinja
{# ✅ Good - Using shared macro #}
{% from 'shared/macros/tables.html' import table_wrapper, table_header %}
{% call table_wrapper() %}
{{ table_header(['Name', 'Email', 'Status']) }}
<tbody>...</tbody>
{% endcall %}
{# ❌ Bad - Copy-pasting table HTML #}
<div class="w-full overflow-hidden rounded-lg shadow-xs">
<div class="w-full overflow-x-auto">
<table class="w-full whitespace-no-wrap">
<thead>...</thead>
<tbody>...</tbody>
</table>
</div>
</div>
```
#### MAC-002: Import Macros at Template Top
**Severity:** Warning
All macro imports should be at the top of the template, after `{% extends %}`.
```jinja
{# ✅ Good #}
{% extends "admin/base.html" %}
{% from 'shared/macros/pagination.html' import pagination %}
{% from 'shared/macros/tables.html' import table_wrapper %}
{% from 'shared/macros/alerts.html' import loading_state %}
{% block content %}
...
{% endblock %}
```
#### MAC-003: Use {% call %} for Wrapper Macros
**Severity:** Error
Wrapper macros that use `{{ caller() }}` must be invoked with `{% call %}`.
```jinja
{# ✅ Good #}
{% call table_wrapper() %}
{{ table_header(['Col1', 'Col2']) }}
{% endcall %}
{% call tabs_nav() %}
{{ tab_button('tab1', 'First') }}
{% endcall %}
{# ❌ Bad - Missing call block #}
{{ table_wrapper() }} {# This won't render inner content! #}
```
#### MAC-004: Document New Macros
**Severity:** Warning
New macros must have JSDoc-style documentation comments.
```jinja
{# ✅ Good #}
{#
Number Stepper
==============
A number input with +/- buttons.
Parameters:
- model: Alpine.js x-model variable (required)
- min: Minimum value (default: 1)
- max: Maximum value (optional)
Usage:
{{ number_stepper(model='quantity', min=1, max=99) }}
#}
{% macro number_stepper(model, min=1, max=none) %}
...
{% endmacro %}
```
#### MAC-005: Add Components to Reference Page
**Severity:** Warning
New shared components should be added to `/admin/components` page with live demos.
---
### Frontend Component Rules (app/templates/**/*.html)
#### FE-008: Use number_stepper Macro for Quantity Inputs
**Severity:** Warning
Use the shared `number_stepper` macro instead of raw `<input type="number">` for consistent styling and dark mode support.
```jinja
{# ✅ Good - Using number_stepper macro #}
{% from 'shared/macros/inputs.html' import number_stepper %}
{{ number_stepper(model='quantity', min=1, max=99) }}
{# ❌ Bad - Raw number input #}
<input type="number" x-model="quantity" min="1" max="99" />
```
**Suppress with `noqa` for ID fields:**
```jinja
{# noqa: FE-008 - User ID is typed directly, not incremented #}
<input type="number" x-model="userId" placeholder="User ID" />
```

# Frontend Component Standards
**Version:** 1.0
**Last Updated:** December 2025
**Audience:** Frontend Developers
---
## Overview
This document defines mandatory standards for all frontend components across Admin, Vendor, and Shop frontends. Following these standards ensures consistency, maintainability, and a unified user experience.
---
## Golden Rules
1. **Use Jinja Macros** - Never copy-paste HTML patterns; use shared macros
2. **Alpine.js for Interactivity** - All client-side logic uses Alpine.js
3. **Dark Mode Required** - Every component must support dark mode
4. **Accessibility First** - ARIA labels, keyboard navigation, focus states
5. **Mobile Responsive** - Mobile-first design with Tailwind breakpoints
---
## Jinja Macro System
### Available Macro Files
All macros are located in `app/templates/shared/macros/`:
| File | Purpose | Key Macros |
|------|---------|------------|
| `pagination.html` | Table pagination | `pagination()`, `pagination_simple()` |
| `alerts.html` | Alerts and toasts | `loading_state()`, `error_state()`, `alert_dynamic()` |
| `badges.html` | Status indicators | `badge()`, `status_badge()`, `role_badge()` |
| `buttons.html` | Button variants | `btn_primary()`, `btn_secondary()`, `action_button()` |
| `forms.html` | Form inputs | `form_input()`, `form_select()`, `form_textarea()` |
| `tables.html` | Table components | `table_wrapper()`, `table_header()`, `table_empty_state()` |
| `cards.html` | Card layouts | `stat_card()`, `card()`, `info_card()` |
| `headers.html` | Page headers | `page_header()`, `page_header_flex()`, `refresh_button()` |
| `modals.html` | Modal dialogs | `modal()`, `confirm_modal()`, `job_details_modal()` |
| `tabs.html` | Tab navigation | `tabs_nav()`, `tabs_inline()`, `tab_button()` |
| `inputs.html` | Specialized inputs | `search_autocomplete()`, `number_stepper()` |
### Macro Usage Rules
#### RULE 1: Always Import Before Use
```jinja
{# ✅ CORRECT - Import at top of template #}
{% from 'shared/macros/tables.html' import table_wrapper, table_header %}
{% from 'shared/macros/pagination.html' import pagination %}
{% block content %}
{% call table_wrapper() %}
{{ table_header(['Name', 'Email', 'Status']) }}
...
{% endcall %}
{{ pagination() }}
{% endblock %}
{# ❌ WRONG - Inline HTML instead of macro #}
{% block content %}
<div class="w-full overflow-hidden rounded-lg shadow-xs">
<div class="w-full overflow-x-auto">
<table class="w-full whitespace-no-wrap">
...
</table>
</div>
</div>
{% endblock %}
```
#### RULE 2: Use Macros for Repeated Patterns
If you find yourself copying HTML more than once, create or use a macro.
```jinja
{# ✅ CORRECT - Using badge macro #}
{{ status_badge(status='active') }}
{{ status_badge(status='pending') }}
{{ status_badge(status='inactive') }}
{# ❌ WRONG - Copy-pasting badge HTML #}
<span class="px-2 py-1 text-xs font-semibold text-green-800 bg-green-100 rounded-full">Active</span>
<span class="px-2 py-1 text-xs font-semibold text-yellow-800 bg-yellow-100 rounded-full">Pending</span>
```
#### RULE 3: Use `{% call %}` for Wrapper Macros
Macros that wrap content use the `caller()` pattern:
```jinja
{# ✅ CORRECT - Using call block #}
{% call table_wrapper() %}
{{ table_header(['Column 1', 'Column 2']) }}
<tbody>...</tbody>
{% endcall %}
{% call tabs_nav() %}
{{ tab_button('tab1', 'First Tab', icon='home') }}
{{ tab_button('tab2', 'Second Tab', icon='cog') }}
{% endcall %}
```
#### RULE 4: Prefer Macro Parameters Over Custom CSS
```jinja
{# ✅ CORRECT - Using size parameter #}
{{ number_stepper(model='qty', size='sm') }}
{{ number_stepper(model='qty', size='lg') }}
{# ❌ WRONG - Adding custom classes #}
{{ number_stepper(model='qty') }}
<style>.my-stepper { transform: scale(0.8); }</style>
```

# E-commerce Components Proposal
**Version:** 1.0
**Created:** December 2025
**Status:** Proposal
**Author:** Development Team
---
## Overview
This document proposes a comprehensive set of reusable Jinja macro components for the shop frontend. These components will standardize the e-commerce experience across all vendor shops while supporting vendor-specific theming via CSS variables.
---
## Design Principles
1. **Vendor Theming** - Use CSS variables (`var(--color-primary)`) for brand colors
2. **Mobile First** - Responsive design starting from mobile
3. **Performance** - Lazy loading, optimized images, minimal JS
4. **Accessibility** - WCAG 2.1 AA compliant
5. **Consistency** - Same UX patterns across all shops
---
## Proposed Components
### Priority 1: Core Shopping Components
#### 1.1 Product Card
**File:** `app/templates/shared/macros/shop/product-card.html`
A versatile product card for grids, carousels, and lists.
```jinja
{{ product_card(
product=product,
show_vendor=false,
show_rating=true,
show_quick_add=true,
size='md', {# sm, md, lg #}
layout='vertical' {# vertical, horizontal #}
) }}
```
**Features:**
- Product image with lazy loading
- Sale badge / "New" badge
- Product title (truncated)
- Price (with strikethrough for sales)
- Star rating
- Quick "Add to Cart" button
- Wishlist heart icon
