elm-effects-proxy

This project provides a monkey patch for XMLHttpRequest that enables side effects as HTTP requests in Elm without the need of using ports.

Motivation

We have to handle a lot of side effects because of the need to interact with privative 3rd party js libraries for our project. Being able to handle side effects as tasks or cmds allowed us to remove lots of boilerplate code and has made all the side effect handling much more understandable.
