A simple AWS SAM template that specifies a few Lambda functions
To start off with I copied this project from the AWS Sam Local Examples page. Make sure you've followed all of the instructions for setup listed here: https://github.com/awslabs/aws-sam-local/tree/develop/samples
To test the api run:
sam local start-api
Run the following command, replacing BUCKET-NAME with the name of your bucket:
sam package --template-file template.yaml --s3-bucket BUCKET-NAME --output-template-file packaged-template.yaml
This creates a new template file, packaged-template.yaml, that you will use to deploy your serverless application.
Run the following command, replacing MY-NEW-STACK with a name for your CloudFormation stack.
sam deploy --template-file packaged-template.yaml --stack-name MY-NEW-STACK --capabilities CAPABILITY_IAM
This uploads your template to an S3 bucket and deploys the specified resources using AWS CloudFormation.
You can run DynamoDB locally too: https://hub.docker.com/r/amazon/dynamodb-local/
Make sure that in any serverless functions that use DyanmoDB that you update the local config to point to the correct port. By default DynamoDB will run on port 8000.
Another note with trying to access the local DynamoDB, that because it's running in docker, you'll notice that we don't access it from the Lambda function with http://localhost:8000, you need to to access http://docker.for.mac.localhost:8081 or it will not work.
Once you have it up and running, you can run npm scripts/createBlogTable.js and npm scripts/createVotesTable.js to create the DynamoDB tables locally for those little applications.
