# Django SSE4HTMX

A simple wrapper around [Django EventStream](https://github.com/fanout/django-eventstream)'s `send_event` to make it
simpler to send a properly formatted HTML fragment rendered from a template or a partial (if you
have [django-template-partials](https://github.com/carltongibson/django-template-partials/tree/main) installed). It
gives you a similar feel to Django's class-based views (CBVs).

## Installation

Install the package using `uv`:

```bash
uv add django-sse4htmx
```

Install the package using `pip`:

```bash
pip install django-sse4htmx
```

Install the package using `poetry`:

```bash
poetry add django-sse4htmx
```

## Usage

```python

from django_sse4htmx import SSEFragmentSender


class MyEventSender(SSEFragmentSender):
    channel_name = 'my_channel'
    template_name = 'my_template.html#my_partial'

    def get_context_data(self):
        # here you can add custom context data to be passed to the template or partial
        return {
            'my_context': 'my_context_value',
            'request': self.kwargs.get('request'),
        }


# in your code anywhere such as a view, a signal responder,
# a queued task in a task queue, etc.:

MyEventSender()(value="some value")  # value is passed to the template or partial as a context variable

# if that syntax bothers you, can also use the `send` method:

MyEventSender().send(value="some value")

# Alternatively if you will use the same sender more than once:

my_sender = MyEventSender()
my_sender(value="some value")
my_sender(value="another value")
my_sender.send(value="yet another value")
```

Any keyword arguments passed to the `__call__` or `send` method will be passed to the template or partial as context
variables.

## Gotchas

- The current request and other values which are normally in the template context will not be there unless you pass them
  explicitly as keyword arguments to the `__call__` or `send` method (as shown in the example above). The current
  request is only available from a view or a middleware, so you may need to adjust your templates (or partials)
  accordingly if your existing template code assumes their presence.

## Code of Conduct

- If contributing or participating in this project in any way, including posting issues or feature requests, you are
  expected to abide by
  the [Python Software Foundation's Code of Conduct](https://policies.python.org/python.org/code-of-conduct/).

## Roadmap

- [x] Initial release, works in quick manual testing with the sample project.
- [ ] Add Unit Tests
- [ ] tox
- [ ] improve documentation
- [ ] Support for i18n/l10n given a language code?
- [ ] Consider adding a way to send multiple events at once (if users even want it, which could happen since HTMX
      supports it)
- [ ] Clean up the demo page layout a bit. It's admittedly rushed, just to get something working quickly.

## Running the Example Project

- [Install `uv`](https://docs.astral.sh/uv/getting-started/installation/) if you haven't already.
- Clone the repository
- `cd` into the cloned repository, then into example
- `uv sync --all-groups` to install the dependencies
- `source .venv/bin/activate`
- `python manage.py runserver`
- Visit [http://127.0.0.1:8000/](http://127.0.0.1:8000/) in your browser

You can watch the JavaScript console to see debugging logs as SSE messages are received.

## Contributing

- The project is using pre-commit hooks to set code style and standards.
- Please fork the repository, install pre-commit `uv tool install pre-commit`, make your changes on a new branch, then
  submit a Pull Request against `main`.

## Changes

- 0.1.1: added repo urls to project config
