Simple API versioning with Go with or without any middleware stack.

# Installation

go get -v github.com/yageek/apiversion

Before tagging a version, an API is identified by a vendor identifier with the form application/vnd.mybusiness.com. If it matches the value of the Accept header, the handler will next try find a version that suits your needs.

AS you can registered several versions for your API, if you don't specify one, the last registered will be selected by default.

To select, one particular version, the handler will match the version specified after within the Accept header after the vendor identifier.

For example, to match the v2 version, the request Accept header will be:

Accept: application/vnd.mybusiness.com-v2

The package works out of the box as a simple HTTP handler or can be integrated easily with any middleware stack.
