AWS Lambda URL Shortener

This is a POC for a url shortening service using AWS APIGW, Lambda and DynamoDB

Endpoints

Create short url

curl -X POST http://YOUR_ID.execute-api.eu-west-1.amazonaws.com/Prod/ --data "{ \"url\":\"https://github.com\"}"

Expand short url

curl -X GET http://YOUR_ID.execute-api.eu-west-1.amazonaws.com/Prod/{linkId}"

How to deploy to AWS

1. Install aws-sam-cli pip install aws-sam-cli
2. Build the lambdas ./build_lambda.sh get_short_url
3. Build the lambdas ./build_lambda.sh create_short_url
4. Package the template sam package --template-file template.yaml --s3-bucket YOUR_CFT_BUCKET --output-template-file packaged.yaml YOUR_CFT_BUCKET can be a new empty bucket.
5. Deploy aws cloudformation deploy --template-file /path/to/file/packaged.yaml --stack-name Url-Shortener-Stack --capabilities CAPABILITY_IAM
6. Navigate to the AWS Console -> Api Gateway -> Your New Api (Url-Shortener)-> Root resource (/) -> Actions -> Deploy Api
7. Voila!

How to run this localy

1. Install aws-sam-cli pip install aws-sam-cli
2. Install docker
3. Build the lambda ./build_lambda.sh get_short_url
4. Run sam sam local start-api
5. Run ./setup_local_dynamodb.sh
6. Update the Lambda Environment(WIP)

You should have a new container running and listening on http://127.0.0.1:3000

This is an early stage WIP/MVP.
