Hi, I'm no core.async expert but I wrote some core-async-heavy code in the past[1].
Async code is contagious. It is better to extract all code which does not need to be async into separate functions and introduce async at the edges of the system. To keep track of my async/non-async code split I adopted pretty useful naming convention. All (async) functions returning channels as a promise (typically using go block internally) should have `go-` prefix. This way it is clear at all call sites that a channel yielding a result is expected. And also this promotes writing functions which are "purely async" - they must always return a channel from all possible branches, as the `go-` prefix suggests. I went as far as writing my own macros to wrap subset of core.async to use this naming convention[2]. just my $.02 Antonin [1] https://github.com/binaryage/dirac/tree/master/src/background/dirac/background [2] https://github.com/binaryage/dirac/blob/master/src/shared/dirac/shared/async.clj On Tuesday, November 13, 2018 at 4:10:48 PM UTC+1, Kashyap CK wrote: > > [Apologies for cross-posting - but I realize that Clojurescript group may > be a better place for this query than the Clojure group :) ] > > Hi all, > > > I am attempting to use core.async to poll a service - > https://gist.github.com/ckkashyap/c8423dcfc3a3f28b67e18ae76cc13f53 > > Broadly, I need to hit the service endpoint with a secret to get a token > and subsequently use the token to poll for messages. > > > I'd appreciate any feedback on the approach - particularly around > > 1.
