The project is written in typescript using the serverless framework. It's configured to deploy in AWS. Every lambda has strict specific permissions and is packaged singulary. The two lambdas are less than 3K in size. The fastest of the two take less than 100ms to answer from a warm state. The other one around ~200ms. Both take less than 500ms from a cold state.
To run locally:
npm install
npx sls dynamodb install
npm run start.local
There are two endpoints:
The body should be a json object with email and message. It will send the message to the email address.
It will return an array of notifications (message, timestamp) sent to that email address.
The notifications are stored in DynamoDB.
To run the tests:
npm sls dynamodb start
npm test
