A Giter8 template for creating an AWS Lambda using Scala.js.
sbt new bgahagan/scalajs-lambda.g8
- Scala.js 1.0 Support
- Uses sbt-scalajs-bundler to manage npm dependencies (for example the AWS SDK)
- Uses sbt-native-packager to bundle lambda function for deployment
Watch for changes and re-compile (from sbt):
> ~fastOptJS::webpack
You can use docker-lambda to test the function locally:
$ docker run --rm \
-v $(pwd)/target/scala-2.13/scalajs-bundler/main:/var/task:ro,delegated \
lambci/lambda:nodejs12.x \
lambda-fastopt-bundle.handler \
'{"body":"world"}'
The handler name will be ${project-name}-fastopt-bundle.handler.
Package the lambda (from sbt):
> universal:packageBin
Deploy the resulting zip in target/universal to AWS Lambda. The handler name will be ${project-name}.handler.
