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

Macro Usage Rules

RULE 1: Always Import Before Use

{# ✅ 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.

{# ✅ 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:

{# ✅ 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

{# ✅ 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>

Creating New Components

#}
{% macro component_name(
    param1,
    param2='default'

<div class="...">
    {# Component HTML #}
