django-sass
===========
The absolute simplest way to use [Sass](https://sass-lang.com/) with Django.
Pure Python, minimal dependencies, and no special configuration required.

Installation
------------
1. Install from pip.
```
pip install django-sass
```
2. Add to your `INSTALLED_APPS` (you only need to do this in a dev environment,
you would not want this in your production settings file, although it adds zero
overhead):
```python
INSTALLED_APPS = [
...,
'django_sass',
]
```
3. Congratulations, you're done 😀
Usage
-----
In your app's static files, use Sass as normal. The only difference is that
you can **not** traverse upwards using `../` in `@import` statements. For example:
```
app1/
|- static/
|- app1/
|- scss/
|- _colors.scss
|- app1.scss
app2/
|- static/
|- app2/
|- scss/
|- _colors.scss
|- app2.scss
```
In `app2.scss` you could reference app1's and app2's `_colors.scss` import as so:
```scss
@import 'app1/scss/colors';
@import 'app2/scss/colors';
// Or since you are in app2, you can reference its colors with a relative path.
@import 'colors';
```
Then to compile `app2.scss` and put it in the `css` directory,
run the following management command (the `-g` will build a source map, which
is helpful for debugging CSS):
```
python manage.py sass app2/static/app2/scss/app2.scss app2/static/app2/css/app2.css -g
```
Or, you can compile the entire `scss` directory into
a corresponding `css` directory. This will traverse all subdirectories as well:
```
python manage.py sass app2/static/app2/scss/ app2/static/app2/css/
```
In your Django HTML template, reference the CSS file as normal:
```html
{% load static %}
<link href="{% static 'app2/css/app2.css' %}" rel="stylesheet">
```
✨✨ **Congratulations, you are now a Django + Sass developer!** ✨✨
Now you can commit those CSS files to version control, or run `collectstatic`
and deploy them as normal.
For an example project layout, see `testproject/` in this repository.
Watch Mode
----------
To have `django-sass` watch files and recompile them as they change (useful in
development), add the ``--watch`` flag.
```
python manage.py sass app2/static/app2/scss/ app2/static/app2/css/ --watch
```
Example: deploying compressed CSS to production
-----------------------------------------------
To compile minified CSS, use the `-t` flag to specify compression level (one of:
"expanded", "nested", "compact", "compressed"). The default is "expanded" which
is human-readable.
```
python manage.py sass app2/static/app2/scss/ app2/static/app2/css/ -t compressed
```
You may now optionally commit the CSS files to version control if so desired,
or omit them, whatever fits your needs better. Then run `collectsatic` as normal.
```
python manage.py collectstatic
```
And now proceed with deploying your files as normal.
Limitations
-----------
* `@import` statements must reference a path relative to a path in
`STATICFILES_FINDERS` (which will usually be an app's `static/` directory or
some other directory specified in `STATICFILES_DIRS`). Or they can reference a
relative path equal to or below the current file. It does not support
traversing up the filesystem (i.e. `../`).
Legal imports:
```scss
@import 'file-from-currdir';
@import 'subdir/file';
@import 'another-app/file';
```
Illegal imports:
```scss
@import '../file';
```
* Only supports `-g`, `-p`, and `-t` options similar to `pysassc`. Ideally
`django-sass` will be as similar as possible to the `pysassc` command line
interface.
Feel free to file an issue or make a pull request to improve any of these
limitations. 🐱💻
Why django-sass?
----------------
Other packages such as
[django-libsass](https://github.com/torchbox/django-libsass) and
[django-sass-processor](https://github.com/jrief/django-sass-processor), while
nice packages, require `django-compressor` which itself depends on several other
packages that require compilation to install.
Installing `django-compressor` in your production web server requires a LOT of
extra bloat including a C compiler. It then will compile the Sass on-the-fly
while rendering the HTML templates. This is a wasteful use of CPU on your web
server.
Instead, `django-sass` lets you compile the Sass locally on your machine
*before* deploying, to reduce dependencies and CPU time on your production web
server. This helps keep things fast and simple.
* If you simply want to use Sass in development without installing a web of
unwanted dependencies, then `django-sass` is for you.
* If you don't want to deploy any processors or compressors to your production
server, then `django-sass` is for you.
* If you don't want to change the way you reference and serve static files,
then `django-sass` is for you.
* And if you want the absolute simplest installation and setup possible for
doing Sass, `django-sass` is for you too.
django-sass only depends on libsass (which provides pre-built wheels for
Windows, Mac, and Linux), and of course Django (any version).
Programmatically Compiling Sass
-------------------------------
You can also use `django-sass` in Python to programmatically compile the sass.
This is useful for build scripts and static site generators.
```python
from django_sass import compile_sass
# Compile scss and write to output file.
compile_sass(
inpath="/path/to/file.scss",
outpath="/path/to/output.css",
output_style="compressed",
precision=8,
source_map=True
)
```
For more advanced usage, you can specify additional sass search paths outside
of your Django project by using the `include_paths` argument.
```python
from django_sass import compile_sass, find_static_paths
# Get Django's static paths.
dirs = find_static_paths()
# Add external paths.
dirs.append("/external/path/")
# Compile scss and write to output file.
compile_sass(
inpath="/path/to/file.scss",
outpath="/path/to/output.css",
output_style="compressed",
precision=8,
source_map=True,
include_paths=dirs,
)
```
Contributing
------------
To set up a development environment, first check out this repository, create a
venv, then:
```
(myvenv)$ pip install -r requirements-dev.txt
```
Before committing, run static analysis tools:
```
(myvenv)$ black .
(myvenv)$ flake8
(myvenv)$ mypy
```
Then run the unit tests:
```
(myvenv)$ pytest
```
