Hi.
What's beautiful about Rails is that it provides the incredibly easy system for API building.
At the same time once you grow and production test the application you start finding that you can make the API interface even better. But you have to break backward compatibility.
How do you handle this situation?
I was initially planning something like DNS versioning and multiple rails deployments (api01.startup.com, api05.startup.com). This plan won't work anymore since there are cases when we will controlling the code, but not the deployment server and DNS setup.
What's the best way to implement API versioning in rails?
