- is a modular event driven application framework written in C
- is an extendable generic framework that can be used for web applications, and many other things
- comes with a very low overhead
- is fast (pretty much as fast as it gets)
- has been production stable for several years serving tens of millions of requests per day
- has high level abstractions like
reactor_server, CouchDB integration and worker pools
The framework depends on libdynamic and libjansson so please install these first.
apt-get install -y build-essential libjansson-dev wget
wget https://github.com/fredrikwidlund/libdynamic/releases/download/v1.3.0/libdynamic-1.3.0.tar.gz
tar fvxz libdynamic-1.3.0.tar.gz
(cd libdynamic-1.3.0; ./configure --prefix=/usr AR=gcc-ar NM=gcc-nm RANLIB=gcc-ranlib; make install)

return REACTOR_OK;
}

reactor_run();
reactor_destruct();
}
