ngx_healthcheck_module VS Mongoose

slow_start also requires the commercial version of nginx. You could try using a 3rd party health check module (like https://github.com/zhouchangxun/ngx_healthcheck_module), and setting a high enough rise count.

3rd party nginx healthcheck module, hasn't been updated in a while, may work ok? There are others out there too.

You can try this module https://github.com/zhouchangxun/ngx_healthcheck_module

I've found myself at this webpage multiple times while trying to minimize the complexity of APIs in my C projects.

My conclusion for now is that C coroutines are something to be left to the implementer. For example: Mongoose (https://github.com/cesanta/mongoose) uses event callbacks to deal with asynchronousness. It is much more pleasant to wrap a library like this in whatever thread/task primitives your system has rather than try to integrate the mythical cross-platform c couroutine.

I remember using mongoose 15 years back. Today i would have considered mongoose(10k+ stars) which is also a mature c/c++ web server[1] if not the licence.

Alternatives at the low to medium level of abstraction include civetweb and mongoose, which have a common ancestor. Both of these appear to be C rather than C++, but seem to be production quality and well-documented. Another C library is cpp-httplib, which is probably too low-level for me.

Since this is only going to be used internally would Mongoose be worth considering?

Here’s an example: https://mongoose.ws/

If you are looking for something simple there is mongoose from cesanta, https://github.com/cesanta/mongoose
