Designing a Pure Python Web Framework

Can you call it pure python if it compiles to React? Seems like the abstraction just makes it harder to debug

All programming is abstractions, unless you're using machine code. Abstractions don't necessarily make debugging harder -- done the right way, they can make it easier.

(Yes, you can call it "pure python" if it compiles to something else, because every programming language compiles to something else.)

machine code is very much still an abstraction

There is an idea that "pure python" means python + python runtime.

For example, pg8000 is a "pure python PostgreSQL driver", but psycopg is not.

Even though both of them only require Python code from their users.

We need to compile down to React/HTML in the end as it's the only way to render a webpage. By "pure Python" we meant from the developer's perspective they won't have to touch React or Javascript.

We only use React for the UI layer and to send events. Since all the state/logic is kept in Python you won't see Javascript errors during runtime, and debugging can mostly be done in Python land.

Wow, you literally got everything wrong in this comment.

- There are a thousand ways to render HTML, you don't need React at all. Even for interactive pages (see recent alternatives like HTMX, or decade old solutions...)

- If it is converted to JS/React it's obviously not "pure" Python. Sorry, but that's just silly to say that.

- You will definitely see JavaScript errors during runtime, it's inevitable. Maybe not with simple toy projects, but with serious projects, it will happen and will make life miserable.

I think they meant that rendering can only be done with JS/HTML, and if you want to use React stuff, React also has to be involved. No need to be rude and assume the worst.

Third point seems true though, I would definitely expect to see JS errors should any React libs have issues on their own.

Would you consider it “pure Python” if it targeted a WASM runtime for the browser side component?

Sounds RIGHT to me. You need a modern front-end framework like React.js if you want to avoid state / component hierarchy nightmares that you find by doing the same with vanilla JS. Also, the statement of working with pure Python resonates well from the dev perspective. Makes sense to me!
