slugify.py
Check the test file next to the source. It shows exactly how this behaves in practice.
Turn any string into a clean URL slug. This does it without pulling in extra packages. Time spent managing dependencies is time not spent shipping features.
This uses the standard Python library. Nothing else to install. No external services to pay for.
Is there an SDK I should install first?
No. slugify.py makes the call over plain HTTP. That keeps the setup down to python3 and a single environment variable. When you are building a SaaS solo, keeping dependencies this small is the whole point.
