Re: TO API Versioning

[Robert Butts]

+1 on Semantic Versioning.

-1 on breaking the existing API again. There's no point versioning if we
make breaking changes without changing the version.

Re: TO API Versioning

[Dewayne Richardson]

Yes, the versioning wasn't consistent because we switched out the database
to Postgres which had several impacts to the API. The issue with API routes
being too granular in the versioning is tricky because the consumers of the
API will need to change as the versions of Traffic Ops moves forward.  Now
that we are on Postgres we plan on a new versioning scheme with /api/v2/*
which we will shortly introduce.  The goal with /api/v2 will be to keep the
response format the same, with the intention of deprecating the /api/1.x
routes.

Another goal we have is to build an API test tool (now that more CRUD
routes are available), which will help with consistency in the API as well
as help us with regression testing (more to come on this front).

Maybe this is a topic that we should discuss at the meetup in May?
