Scala.js AWS Lambda Template

A Giter8 template for creating an AWS Lambda using Scala.js.

sbt new bgahagan/scalajs-lambda.g8

Features

• 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

Development

Watch for changes and re-compile (from sbt):

> ~fastOptJS::webpack

Running locally

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.

Deploy

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.
