cloudFunction-Round2

This codebase is created to experiment with AWS Lambda. The goal is to use SAM to deploy and publish the lambda function using Cloud formation.

Setup

• Setup AWS CLI (details see https://docs.aws.amazon.com/lambda/latest/dg/setup-awscli.html)
• Setup SAM Local (details see https://docs.aws.amazon.com/lambda/latest/dg/sam-cli-requirements.html)
• Install NodeJS and NPM
• Clone the repo
• Run "npm install"

Package

Run the following command to package the local artifacts (defined in template.yaml file) and upload them to S3 bucket and create a new template file with references to S3 bucket.

sam package --template-file template.yaml --s3-bucket mybucket --output-template-file output.yaml

Deploy

Run the following command to create and execute changeset as described in the cloud formation template (output.yaml).

sam deploy --template-file ./output.yaml --stack-name mystack --capabilities CAPABILITY_IAM

Unit Tests

Run "npm test" to execute unit tests

Functional Tests

Generate S3 event using:

sam local generate-event s3 --bucket localTestBucket --key test-key > event_file.json

sam local invoke AddReviewDocumentToList -e event_file.json
