sierra-streams-source
A library for providing Akka Streams from objects in a Sierra API.
Installation
libraryDependencies ++= Seq(
"uk.ac.wellcome" %% "sierra-streams-source" % "0.4"
)
sierra-streams-source is published for Scala 2.11 and Scala 2.12.
Basic Usage
import akka.stream.scaladsl.Sink
import uk.ac.wellcome.sierra.{SierraSource, ThrottleRate}
import scala.concurrent.duration._
val sierraSource = SierraSource(
sierraUrl,
oauthKey,
oauthSecret,
ThrottleRate(4, 1.second)
)(
"items",
Map(
"updatedDate" -> "[2013-12-10T17:16:35Z,2013-12-13T21:34:35Z]"
)
)
val eventualJsonList = sierraSource.runWith(Sink.seq[Json])
eventualJsonList.map(jsonList => {
// Do stuff
})
Development
If you want to release this library you'll need credentials to authenticate with Travis and Sonatype.
Releasing to Sonatype
Create a file credentials.sbt in the root of the repo with the following contents (but with the correct details).
credentials += Credentials("Sonatype Nexus Repository Manager",
"oss.sonatype.org",
"(Sonatype user name)",
"(Sonatype password)")
pgpPassphrase := Some("(PGP password)".toCharArray)
Then run publishSigned and sonatypeRelease in sbt to push a release:
sbt ++2.11.11 publishSigned sonatypeRelease;
Packaging for Travis
To encrypt credentials.sbt for Travis you can use the following command:
docker run -v $(pwd):/project \
-v ~/.travis:/root/.travis \
-it skandyla/travis-cli \
encrypt-file credentials.sbt
You will then need to copy the specified output to .travis.yml if different from what is already in that file.
For example:
- stage: release
scala: 2.12.6
script:
# Output like this will be specified from the travis cli tool
- openssl aes-256-cbc -K $encrypted_83630750896a_key -iv $encrypted_83630750896a_iv -in credentials.sbt.enc -out credentials.sbt -d
