django-htmx VS viewflow

If you don't already, you should use django-htmx. This will allow you to check if the request was made with HTMX. You can then do something like this:

To make things easier, install the django-htmx package. Then, in your Page model's serve(), you can do things like if request.htmx: and return an HTML snippet instead of the full page in that case.

The great thing about HTMX is it fits really nicely with templated server-rendered frameworks like Django.

You can have a page with a list of items. The page is one template, and it includes a sub-template which is just the

items. Then you have a separate view for "get list fragment" which just returns the updated/sorted/filtered

. If you toggle the ordering, or filter the list, HTMX will automatically call the fragment renderer and replace just the

items, without reloading the page.

See this example: https://github.com/adamchainz/django-htmx/blob/8054f049f53f0...

This approach solves the common interactivity use-cases requiring JS in a server-rendered app, without having to write any JS, and without having to build a REST API. Instead you just render HTML, which your framework is excellent at.

If you use django-htmx, it's pretty simple to get the "this HTTP request came from HTMX" flag and branch accordingly in your view. The docs give a simple example of the logic here:

https://django-htmx.readthedocs.io/en/latest/middleware.html...

The examples give a fleshed-out version: https://github.com/adamchainz/django-htmx/blob/main/example/...

Though that's very slightly different than how I described it above, but it's basically the same idea; in this case you commonize the `main` block between the two contexts.

HTMX has a HX-Trigger response header that enables you to trigger events in the browser that Javascript code can listen for. Assuming you already have Django-HTMX library set up, you could write a middleware like this:

Nice. I've written some less complete, less consistent variant of this a couple times now. That alone may be worth taking the dependency.

I think it's fair to clarify that Adam Johnson (aka adamchainz on Reddit and GitHub) didn't create HTMX but did write the django-htmx app to make it easier to use HTMX in Django.

django-htmx also comes with it's own version of HttpResponseHtmxRedirect (called HttpResponseClientRedirect).

viewflow supports BPMN: https://github.com/viewflow/viewflow

I'm developing a web application to learn Django (python 3.4 & Django 1.6.10). The web app has complex and often updated workflows. I decided to integrate the Django-Viewflow library (https://github.com/viewflow/viewflow/) as it seems to be a very convenient way to handle workflows and not incorporate the workflow logic with the application models.

https://github.com/viewflow/viewflow seems to be at least partially overlapping what you're looking for.

I'm working on render django forms to Web Compoments, so any styling could be done on the client side.
