The Robustness Principle

14 Mar 2017 I learned about this at a talk called "Implementing Evolvable APIs" at SXSW: https://en.wikipedia.org/wiki/Robustness_principle

For example, making an API that throws errors when an unexpected parameter is provided is a bad idea. What if you need to make changes to the client to add the new parameter? You will need to make sure you deploy the code on the server side first, otherwise it will cause errors.
