graphql-clj library tries to support both Clojure 1.9 and 1.8. The way it does:
Library use Clojure 1.9 as dependency. For project uses Clojure 1.8 and depends on graphql-clj, it has a few options: 1. Don't use the namespace with clojure.spec or 2. Add https://github.com/tonsky/clojure-future-spec as dependency, clojure.spec backport will be available. Caveat: For some new functions introduced in clojure.core 1.9, simply copied those functions to library. You can find more detail in https://github.com/tendant/graphql-clj/pull/32 On Sunday, October 23, 2016 at 8:49:33 AM UTC-7, Cal Loomis wrote: > > The only discussion I’ve seen about providing conditional support for spec > in libraries is in the old thread started by Sean Corfield for the JDBC > library: > > https://groups.google.com/d/msg/clojure-dev/4VAlKZxiN94/tNQo_4yABAAJ > > Is the technique described there, the recommended best practice?
