(Nerd alert! This post is a small technical snippet for Python and Django programmers. If you don't know what those proper nouns mean, don't worry — feel free to skip this post.)
Buttondown has used django-js-reverse since its inception to route backend API urls from the Django backend to the Vue frontend.
This has been (not to damn with faint praise!) better than nothing: some kind of syncing mechanism certainly beats having to manually correlate backend routes with frontend definitions. But there are two nits I've had with the package:
Urls.email_detail("foo")) are not caught until runtime.
email-detail) but via camel or snake case (
Urls.email_detail()). This attempt at ergonomics makes it trickier to actually find all invocations of a route at a glance.
Naturally, I thought to myself: why not try my hand at building a better version? I'm happy to share that it was fairly painless: while I'm still a little bit away from formally open-sourcing this as a package (there are a number of administrative tasks like registering with PEP and settling on a name that I need to take care of), here is the total implementation — 34 lines of Python and 4 lines of templated TypeScript.
I am confident this implementation is missing many, many, many edge cases. It does not handle URL namespacing nor non-string parameters, nor I'm sure many other things. But it is a step change improvement to Buttondown's codebase, and I'm excited to have it. Please let me know if you find it useful, or if you have any feature requests/suggestions — I promise to update this blog post with a link to the repository once it's published to PEP.
