UrlShortner

UrlShortner using Amazon Web Services, Serverless Application Model. For this service we use CloudFormation to build a stack composed by API Gateway, Lambda and DynamoDB powered by DAX.

Architecture

Development

For local development, follow the steps below:

1. First, we need to setup a local DynamoDB. For this, run the command from the root project. This will run docker with the configurations in the docker-compose.yml file

   docker-compose up -d

2. Install node dependencies

   npm install

3. Now, we are ready to go. To run lambda, you just need to run the command provided below and change json payload on lambda/test.js file, which represents the payload lambda will receive from API Gateway

   npm run local

Deployment

1. Make a zip file with necessary folders

   zip -qur urlshortner node_modules lambda

2. Create a S3 bucket in case you don't have one

   aws s3 mb s3://<bucket-name>

3. Create an AWS CloudFormation package of the code in that bucket

   aws cloudformation package --template-file template.yaml --output-template-file packaged-template.yaml --s3-bucket <bucket-name>

4. Finally, deploy the AWS CloudFormation stack which will create all the resources defined in the YAML file

   aws cloudformation deploy --template-file packaged-template.yaml --stack-name urlshortner
