diversion v0.4.6

Diversion

Diversion is an API versioning proxy based on bouncy and semver, with an optional REST management API made with Lazorse. It interprets the X-Version header of incoming requests as version range, then uses semvers maxSatisfying algorithm to choose a backend. This means you have all the power of npm's version ranges (including ~0.2.1 style matching) in your X-Version headers.

Diversion can automatically remove failed backends and retry requests, but currently the algorithm is a bit overzealous and has no health checking, so it's quite possible to end up with no live backends due to transient failure.

Also included is a management API that listens on a different port and allows backends to register themselves with the proxy.
