Litestar is worth a look
A few years ago at work, I had a project which offered an opportunity to look at the new generation of async-first, type-hint-driven Python web frameworks. For reasons which aren’t particularly relevant today, on that project I ended up choosing Litestar, which is the one that doesn’t have a ravenous all-consuming hype machine surrounding it. And I’m very glad I did, because today I’m more convinced than ever it was the right choice, and for the last 18 months or so every new project I’ve started at my day job has been built with Litestar.
But even if you’re someone who does Python web apps for a living, and even if you’re someone who builds asynchronous type-hint-driven web apps, you might not be familiar with this absolute gem of the Python web ecosystem, and today I want to remedy that.
You save this as app.py, run with litestar run or hand it directly to the ASGI server of your choice, and it launches a web application. You go to /greet?name=Bob and it replies “Hi, Bob!”. Leave out the name parameter and it responds with an HTTP 400 telling you the name parameter is required.
