Cognitect's aws-api and babashka. Aw yeah.
Alpha Only gently tested.
awyeah-api is another Clojure library which provides programmatic access to AWS services from your Clojure or babashka program. Its raison d'être is to be a drop-in replacement for Cognitect's brilliant aws-api that will work from source with babashka.
awyeah-api should work with com.cognitect.aws/endpoints and
com.cognitect.aws service packages.
This port is based on the great work done by the fine folks at Cognitect. I am not affiliated with Cognitect and this is not a Cognitect-distributed library.
Requires babashka 0.7.0 or later (clojure.spec.alpha support).

(prn buckets)The awyeah-api client does not auto-refresh AWS credentials. The aws-api behavior relies on features that aren't present in babashka, and I haven't figured out an alternative implementation of the behavior. My use case is short-lived scripts, where JVM start-up time can dwarf script execution time: credentials don't have much time to get stale. If I had longer-lived processes, start-up time wouldn't be an issue and I'd just use the Clojure.
The com.cognitect/http-client used by aws-api automatically
uncompresses S3 objects if they have the appropriate content-type
metadata in S3. I've chosen not to replicate this behavior with the
bundled HTTP client based on java.net.http as I think it's a bit of
a misfeature to have enabled by default in a programmatic client
library like this. (That said, that makes it less of a drop-in
replacement, doesn't it? I may revisit this.)
See Porting Decisions if you're interested in the nitty gritty or are wondering why I made some decision or other.
