Shorten That URL

URL shortener app, build with Flask, deployed with Zappa to AWS Lambda and Dynamo DB.

Testing and Development

Setup

Install the package (in editable mode) and the development dependencies:

python -m pip install -e ".[develop]"

Testing (and development for that matter) requires a running local instance of Dynamo DB. The easiest way to get there is to have Docker on the testing machine, and download and run the local version of DynamoDB. See also: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.html https://hub.docker.com/r/amazon/dynamodb-local

To get the official DynamoDB docker image:

docker pull amazon/dynamodb-local

Then start the local container with:

docker run -p 8000:8000 amazon/dynamodb-local

Running the Tests

Run the tests simply with

pytest

Deployment

This requires that AWS certificate for authentication and authorization is installed on the machine from which you are deploying. See this guide to setup AWS credential on your machine: https://aws.amazon.com/blogs/security/a-new-and-standardized-way-to-manage-credentials-in-the-aws-sdks/

Once this is in place, the initial deployment can be done with Zappa like so:

$ zappa deploy production
Deploying..
Your application is now live at: https://7k6anj0k99.execute-api.us-east-1.amazonaws.com/production

For development deployment, use dev instead of production.

To an updated version of the Lambda function use:

$ zappa update production
Updating..
Your application is now live at: https://7k6anj0k99.execute-api.us-east-1.amazonaws.com/production
