I am just getting started with Clojurescript. I wrote some clojurescript code to use the shared aws credentials file to initialize S3 client and list buckets . However my code does not work.
(defn -main [arg1 arg2]
(println "hello")
(let[ creds (new AWS/SharedIniFileCredentials #js{:profile "superman"})
_ (AWS/config.update creds)
; dump out the accesskey to check if it has the correct profile
_ (AWS/config.getCredentials (fn [err] (if (nil? err) (do
(println "its good")
(println AWS/config.credentials.accessKeyId)))))
s3 (new (.-S3 AWS ))
] (.listBuckets s3 (fn[err buckets] (println "err: " err) (println buckets) )) ))
The AWS/config.getCredentials in the above does pick up the correct profile as seen from (println AWS/config.credentials.accessKeyId)
. The listbuckets code throws the following error:
#object[NodeError TypeError [ERR_INVALID_ARG_TYPE]: The "key" argument must be of type string or an instance of Buffer, TypedArray, DataView, or KeyObject. Received undefined]
I have Google AWS SDK S3 clojuresript AND is the only link I found . I used that to configure the S3 client but that does not seem to work
I would appreciate any help.
I checked it and the problem seems to be that SDK expects the credentials to be set before anything else, before instantiating the S3 client.
The following works for me on a minimal project with shadow-cljs:
(ns server.main
(:require ["aws-sdk" :as aws]))
(defn main! []
(println "App loaded...")
(let [creds (aws/SharedIniFileCredentials. #js {:profile "example-profile"})
_ (set! (.-credentials aws/config) creds)
s3 (aws/S3.)]
(.listBuckets s3 (fn [err data]
(if err
(println "ERROR:" err)
(println "OK:" data))))))
when I run it:
$ node target/main.js
App loaded...
OK: #js {:Buckets #js [#js {:Name dummy-test-bucket, :CreationDate #inst "2019-05-05T17:32:17.000-00:00"} #js {:Name mydomain.com, :CreationDate #inst "2018-06-19T04:16:10.000-00:00"}], :Owner #js {:DisplayName username, :ID f63f30bc25ab3609b8d3b5be6b3a872dd2c9f7947b2d509e2338357d93e74f2}}
