I’ve just pushed out a new version of Function Monkey with one fairly minor but potentially important change – the ability to create functions without routes.
You can now use the .HttpRoute() method without specifying an actual route. If you then also specify no path on the .HttpFunction<TCommand>() method that will result in an Azure Function with no route specified – it will then be named in the usual way based on the function name, which in the case of Function Monkey is the command name.
I’m not entirely comfortable with the approach I’ve taken to this at an API level but didn’t want to break anything – next time I plan a set of breaking changes I’ll probably look to clean this up a bit.
The reason for this is to support Logic Apps. Logic Apps only support routes with an accompanying Swagger / OpenAPI doc and you don’t necessarily want the latter for your functions.
While I was using proxies HTTP functions had no route and so they could be called from Logic Apps using the underlying function (while the outside world would use the shaped endpoint exposed through the proxy).
Having moved to a proxy-less world I’d managed to break a production Logic App of my own because the Logic App couldn’t find the function (404 error). Redeployment then generated a more meaningful error – that routed functions aren’t supported. Jeff Hollan gives some background on why here.
I had planned a bunch of improvements for 2.1.0 (which I’ve started) which will now move to 2.2.0.
