Easy, flexible icons for Django

Django Easy Icons

Easy, flexible icons for Django templates with support for multiple rendering backends.

Overview

Django Easy Icons provides a simple, consistent way to include icons in your Django templates. It supports multiple icon sources including SVG files, font icon libraries (like Font Awesome), and SVG sprite sheets.

Features

• Multiple Renderers: Support for SVG files, font icons, and sprite sheets
• Template Integration: Simple {% icon %} template tag
• Flexible Configuration: Configure multiple icon sets with different renderers
• Attribute Merging: Easily add classes and attributes to icons
• Caching: Built-in renderer caching for performance

Installation

pip install django-easy-icons

Add easy_icons to your INSTALLED_APPS:

INSTALLED_APPS = [
    # ... other apps
    'easy_icons',
]

Quick Start

1. Configure Icon Renderers

Add configuration to your Django settings:

EASY_ICONS = {
    "default": {
        "renderer": "easy_icons.renderers.SvgRenderer",
        "config": {
            "svg_dir": "icons",  # Template directory for SVG files
            "default_attrs": {
                "height": "1em",
                "fill": "currentColor"
            }
        },
        "icons": {
            "home": "home.svg",
            "user": "user.svg",
            "settings": "cog.svg"
        }
    }
}

2. Use in Templates

{% load easy_icons %}

<!-- Basic usage -->
{% icon "home" %}

<!-- With additional attributes -->
{% icon "user" class="nav-icon" height="2em" %}

<!-- Using specific renderer -->
{% icon "heart" renderer="fontawesome" %}

3. Use in Python Code

from easy_icons import icon

# Basic usage
home_icon = icon("home")

# With attributes
user_icon = icon("user", **{"class": "large", "data-role": "button"})

# Using specific renderer
fa_icon = icon("heart", renderer="fontawesome")

Renderers

SVG Renderer

Renders icons from SVG template files:

EASY_ICONS = {
    "svg": {
        "renderer": "easy_icons.renderers.SvgRenderer",
        "config": {
            "svg_dir": "icons",
            "default_attrs": {"class": "svg-icon"}
        },
        "icons": {
            "home": "house.svg",
            "user": "person.svg"
        }
    }
}

Provider Renderer

For font icon libraries like Font Awesome:

EASY_ICONS = {
    "fontawesome": {
        "renderer": "easy_icons.renderers.ProviderRenderer",
        "config": {
            "tag": "i"
        },
        "icons": {
            "home": "fas fa-home",
            "user": "fas fa-user",
            "heart": "fas fa-heart"
        }
    }
}

Sprites Renderer

For SVG sprite sheets:

EASY_ICONS = {
    "sprites": {
        "renderer": "easy_icons.renderers.SpritesRenderer",
        "config": {
            "sprite_url": "/static/icons.svg"
        },
        "icons": {
            "logo": "brand-logo",
            "menu": "hamburger-menu"
        }
    }
}

Configuration

Multiple Renderers

You can configure multiple renderers and choose which one to use:

EASY_ICONS = {
    "default": {
        "renderer": "easy_icons.renderers.SvgRenderer",
        "config": {"svg_dir": "icons"},
        "icons": {"home": "home.svg"}
    },
    "fontawesome": {
        "renderer": "easy_icons.renderers.ProviderRenderer",
        "config": {"tag": "i"},
        "icons": {"heart": "fas fa-heart"}
    },
    "sprites": {
        "renderer": "easy_icons.renderers.SpritesRenderer",
        "config": {"sprite_url": "/static/icons.svg"},
        "icons": {"logo": "brand"}
    }
}

Use in templates:

{% icon "home" %}  <!-- Uses default renderer -->
{% icon "heart" renderer="fontawesome" %}
{% icon "logo" renderer="sprites" %}

Default Attributes

Configure default attributes that will be applied to all icons from a renderer:

"config": {
    "default_attrs": {
        "class": "icon",
        "aria-hidden": "true",
        "height": "1em"
    }
}

Note: Template tag attributes completely override default attributes - they don't merge.

Attribute Overriding

Template tag attributes override default attributes:

• Provided attributes completely replace defaults: height="1em" + height="2em" = height="2em"
• This includes class attributes: class="icon" + class="large" = class="large"

Advanced Usage

Custom Renderers

Create custom renderers by extending BaseRenderer:

from easy_icons.base import BaseRenderer
from django.utils.safestring import SafeString

class CustomRenderer(BaseRenderer):
    def render(self, name: str, **kwargs) -> SafeString:
        resolved_name = self.get_icon(name)
        attrs = self.build_attrs(**kwargs)
        html = f'<custom-icon {attrs}>{resolved_name}</custom-icon>'
        return self.safe_return(html)

Disable Default Attributes

Use use_defaults=False to ignore default attributes:

{% icon "home" use_defaults=False class="only-this-class" %}

icon("home", use_defaults=False, **{"class": "only-this-class"})

Testing

Run the test suite:

# Install dependencies
poetry install

# Run tests
poetry run pytest

# Run tests with coverage
poetry run pytest --cov=easy_icons --cov-report=html
