brownlabs/todo_list_api

Small project that implements a To-Do list on a serverless environment using AWS API Gatway, Lambda and DynamoDB.

todo-list-api

What's this?

An application that I'm using to learn about AWS and software engineering in general.

It will be a simple To-Do List API following a CRUD approach with the following resources:

• Amazon HTTP API Gateway: as the main entrypoint
• AWS Lambda: all the business code will run over this serverless solution
• DynamoDB: our NoSQL database

I'm trying to do a commit for each major change:

• 76edcf8ae38c782f77258be61f285b73a0ad1f74 - the inital CRUD application that is completely functional and ready to work
• 5fb7fc87b6984ffad3b35560e5873bae50d32ec0 - added CORS support and a mini Web Application to test it
• 18d2426ca23ce689d39d6f24618f30ce7f313076 - use Lambda Layers for reusable code

How To's

Create docker network:

docker network create lambda-local

Create the dynamodb container:

docker run -p 8000:8000 -d --rm --network lambda-local --name dynamodb -v {your-user-root-folder}/.docker/dynamodb:/data/ amazon/dynamodb-local -jar DynamoDBLocal.jar -sharedDb -dbPath /data

Run the local SAM template API:

sam local start-api --docker-network lambda-local --parameter-overrides AWSENV=AWS_SAM_LOCAL

Run the unit tests:

python3 -m unittest discover tests/unit/ -bv

Validate the SAM template:

sam validate

Build the SAM stack:

sam build

Deploy the SAM stack:

sam deploy --guided

Delete the SAM stack:

sam delete --stack-name todo-list-api
