This is my attempted at something that makes using Common Lisp with Datastar easier. To test the SDK I made this demo that shows the simulation of the Cassini-Huygens mission using the NASA SPICE toolkit and JPL Horizons API: https://dataspice.interlaye.red/
The Datastar API itself is very simple, 3 functions or so, I ended up wasting a lot more time on stuff like leeping the SSE stream open, compression support (zstd only atm), and trying to use CLOS in a way that would fit both Hunchentoot and Clack (not always easy).
Very nice, thank you. The tests directory is good for testing, and I suggest adding an examples directory with a few very short and complete simple examples.
I haven't tried Wookie, since adding Clack+Woo was already a substantial change. Reading https://fukamachi.hashnode.dev/woo-a-high-performance-common... , where it compares with Wookie, I'm not sure if it would make a difference: it might be wrong, but "it says:
> Of course, this architecture also has its drawbacks as it works in a single thread, which means only one process can be executed at a time. When a response is being sent to one client, it is not possible to read another client's request.
... which for SSE seems to be similar to what the issue is with Woo. I wrote a bit more on it in https://github.com/fsmunoz/datastar-cl/blob/main/SSE-WOO-LIM... , and it can be more of a "me" problem than anything else, but to keep a SSE stream open, it doesn't play well with async models. That's why I added a with-sse-response macro that, unlike with-sse-connection, sends events without keeping the connection open.
The CL-SPICE library I used, that wraps the SPICE C library through CFFI, doesn't cover the type of SPICE kernel that I wanted to use for the Comms module. I could try and add it, but it could be more involved than what I expected and put the thing on hold.
So I used the FORTRAN SDK for SPICE, since I had used it before, and it's reasonably small and easy. The alternative coud be using the C SDK, but I went with FORTRAN since I already had most of the code from a previous project.

Have you tried wookie? Such extreme case of blocking the event loop... negates any benefit of async processing.
