Management command for downloading HTMX about django-htmx

[adamchainz]

I reconsidered this after several further requests over the years. #428 has a possible implementation.

No the project deliberately doesn't bundle htmx or provide any way of doing so, since there are too many ways you might want to embed htmx - from a CDN, your own static files, or via a JS bundler npm, and with or without extensions. The download script there is to make the example app more manageable and you're free to adapt it.

Hi @kytta @adamchainz

if HTMX is an integral part of our development project, it seems useful to me to declare it as a parameter, as Django compressor does

to perform this operation we need to add these news settings:

• HTMX_VERSION
• HTMX_EXTENSIONS
• HTMX_STATIC_ROOT
• HTMX_STATIC_URL

All news settings have the prefix HTMX_

HTMX_VERSION = "1.9.11"

Indicate the htmx version to download

HTMX_EXTENSIONS = [
    "htmx.js",  # mandatory for django-htmx
    "ext/debug.js",  # mandatory for django-htmx
    "ext/event-header.js",  # mandatory for django-htmx
    "https://github.com/orgname/repos/main/src/",
    "https://raw.githubusercontent.com/bigskysoftware/htmx-extensions/main/src/head-support/head-support.js",
    "https://unpkg.com/browse/[email protected]/dist/csrf-token.js",
]

By default HTMX_EXTENSIONS have these values:

• htmx.js
• ext/debug.js
• ext/event-header.js

we need to define where to store the download files

HTMX_STATIC_ROOT = "static_htmx/"
# or
HTMX_STATIC_ROOT = "/opt/django_tuto/static_htmx/"

HTMX_STATIC_ROOT is the original folder to collect the HTMX files with command downloadhtmx or htmx download

HTMX_STATIC_URL = "htmx"

by default the static URL for htmx STATIC_URL + HTMX_STATIC_URL

After call the download hmtx command, we can call the collectstatic command.

STATICFILES_DIRS = [
    ...
    (HTMX_STATIC_URL, HTMX_STATIC_ROOT),
]

On the html template we can use these to include the htmx files

<script src="{% static 'htmx/myjsfile.js' %}"></script> 

With these settings, no need to pass extra arguments on the command line.

just execute commands in this order

python manage.py downloadhtmx (or htmx download)
python manage.py collectstatic

What do you think ?
