I've wanted to do just this. I've used libmicrohttpd, and... it's not my favorite. But if you're going to do it in C then libmicrohttpd is probably the best API to use. You get bonus points for using jq :)

If you're also using jq you might as well ditch Jansson and use jq's `jv` API. I highly recommend it.

One thing that sold me on Jansson is that you can set custom allocators which work very well with the request arena. Once those allocators are set the json objects continue to use the arena even when used in middleware. This makes memory management a cinch!

From what I can tell jq’s C lib doesn’t yet expose a way to set custom allocators.

You can set a custom allocator, but it's global. You could contribute a feature to set thread-local custom allocators -- it'd be quite easy.

		Oh right, no, jq has a custom out-of-memory handler. But it should be trivial to extend src/jv_alloc.[ch] to let you set not just a custom nomem handler but also a custom allocator, and then you can use thread-locals in your allocator.
