AppSync Emulator Deprecation notice

We've worked with AWS over the last few months to transition ownership of the emulator directly into Amplify's (and AWS) hands.

Please see: https://www.linkedin.com/feed/update/urn:li:activity:6565000058121572352 for details. We will be deprecating the package shortly.

Prerequisites

• Java version >= 8
• Python 3
• Golang 1.x
• aws-sam-cli

This repo tests that Go and Python serverless functions work. For the specs to run, you will need both Python 3 and Golang installed and to have built the Go files using the .compileAll.sh script.

Developing

Clone this repo and build everything:

git clone git@github.com:ConduitVC/aws-utils.git
cd aws-utils
go get -u github.com/aws/aws-lambda-go/lambda
./compileAll.sh
yarn install

Then make sure all the specs pass:

This mono repo runs all tests through jest (including eslint!) to run the tests you first need to start docker-compose to make the localstack services available.

docker-compose run -d localstack
docker-compose run wait
yarn test

If you find the tests running slowly or with intermittent failures, try running this once to clear the Jest cache:

yarn test --clearCache

Also, check that you have enough RAM allocated to Docker. 4GB would be a good starting point.

It may help to use yarn test --runInBand to stop the localstack stuff getting overwhelmed by the default parallel tests.

To debug the tests, do this:

NODE_DEBUG=appsync-emulator:lambdaRunner TERM=dumb yarn test

Without TERM=dumb, any console.log() or log messages will be swallowed by Jest as it scrolls up to replace its own output.
