Peter Taoussanis 839143167b [mod] Simplify middleware - don't auto compose ... Previously: It was possible to provide a vector of middleware fns when creating signals or adding handlers, e.g.: (event! ::ev-id1 {:middleware [fn1 fn2 ...]}), (add-handler! ::handler-id1 <handler-fn> {:middleware [fn1 fn2 ...]}) After this commit: Middleware is always expected to be a single fn, or nil. A `comp-middleware` util has been added to make it easy to compose multiple middleware fns into one. Motivation: The previous (auto-composition) behaviour was nice when adding handlers, but incurred a (small but non-trivial) runtime cost when creating signals. The actual benefit (convenience) of auto-composition is very small, so I've decided to just remove this feature and add the `comp-middleware` util. Note that I ruled out the option of doing auto-comp only when adding handlers since that've meant an inconsistency and so complexity for little benefit.		2024-05-05 13:58:16 +02:00
