I know this isn't really HTMX based, but this is the best community I've found for asking questions like this: I've decided that some 3rd-party APIs I use are taking too long to respond, making the request-response cycle for my own website too lengthy (e.g., a button that adds someone to a ConstantContact email list.. I get the request, fire off a payload to the ConstantContact API, which takes too long, and then send response to the user). I don't think I want anything as heavy-weight or full-featured as celery, but I just have a handful of instances where I want to return a response and then process some code. Any suggestions for what I should look into?
