Great news! 🎉 Awyeah-api is a babashka compatible re-implementation of Cognitect's aws-api! This means that this pod is no longer necessary, and will no longer be maintained. Please use Awyeah-api.
A babashka pod wrapping the aws-api library.
Experimental, awaiting your feedback.
The namespaces and functions in this pod reflect those in the official aws-api library.
Available namespaces and functions:
pod.babashka.aws:client,doc,invokepod.babashka.aws.config:parsepod.babashka.aws.credentials:credential-process-credentials-provider,basic-credentials-provider,default-credentials-provider,fetch,profile-credentials-provider,system-property-credentials-providerpod.babashka.aws.logging:set-level!

- This pod doesn't require adding dependencies for each AWS service.
- Async might be added in a later version.
- For uploading (big) files (e.g. to S3), it is better for memory consumption to
pass a
java.io.Filedirectly, rather than an input-stream.
The default behaviour for credentials is the same way as Cognitect's
aws-api; meaning the
client implicitly looks up credentials the same way the java SDK
does
.
To provide credentials explicitly, you can pass a credentials-provider to the
client constructor fn, e.g.:
(require '[pod.babashka.aws :as aws])
(require '[pod.babashka.aws.credentials :as credentials])
(def s3 (aws/client {:api :s3
:credentials-provider (credentials/basic-credentials-provider
{:access-key-id "ABC"
:secret-access-key "XYZ"})}))In contrast to the aws-api library this pod does not support extending the
CredentialsProvider interface. For more complex flows, e.g. temporary
credentials obtained by AWS SSO, one can use a credential_process entry in a
~/.aws/credentials file, as documented here:
(def s3 (aws/client {:api :s3
:credentials-provider (credentials/credential-process-credentials-provider
"custom-profile")}))where ~/.aws/credentials could look like
[custom-profile]
credential_process = bb fetch_sso_credentials.clj
The credential_process entry can be any program that prints the expected JSON data:
#!/usr/bin/env bb
(println "{\"AccessKeyId\":\"***\",\"SecretAccessKey\":\"***\",\"SessionToken\":\"***\",\"Expiration\":\"2020-01-00T00:00:00Z\",\"Version\":1}")The aws-api includes clojure.tools.logging using the default java.util.logging
implementation. Use pod.babashka.aws.logging/set-level! to change the level of
logging in the pod. The default log level in the pod is :warn. All possible
levels: :trace, :debug, :info, :warn, :error or :fatal.
Each aws-api client has its own logger which adopts the logging level of the global logger at time it was instantiated.

Run script/update-deps.clj.
Run script/test. This will run both the pod and tests (defined in
test/script.clj) in two separate JVMs.
To test the native-image together with babashka, run the tests while setting
APP_TEST_ENV to native:
APP_TEST_ENV=native script/testTo test with localstack:
# Start localstack
docker-compose up -d
# Set test credentials and run tests
AWS_REGION=eu-north-1 AWS_ACCESS_KEY_ID=test AWS_SECRET_ACCESS_KEY=test script/testWhen adding new services to tests you need to add the service name into SERVICES environment variable in docker-compose.yml and .circleci/config.yml. See localstack docs for a list of available services.
