Functionless URL Shortener

This app creates a URL shortener without using any compute. All business logic is handled at the Amazon API Gateway level. The basic app will create an API Gateway instance utilizing Api Keys for authentication and authorization. It will also create an Amazon DynamoDB table for data storage.

Requirements for deployment

Deploying

Note: This stack includes an Amazon CloudFront distribution which can take around 30 minutes to create. Don't be alarmed if the deploy seems to hang for a long time. In the terminal, use the SAM CLI guided deployment the first time you deploy

sam deploy -g

sam deploy -g --config-file samconfig.toml --config-env prd

Choose options

You can choose the default for all options except GithubRepository and **

## The name of the CloudFormation stack
Stack Name [URLShortener]:

## The region you want to deploy in
AWS Region [ap-south-1]:

## The name of the application (lowercase no spaces). This must be globally unique
Parameter AppName [shortener]:

## AWS OrgId to protect APIs using IAM Auth to only account related to AWS Orgs 
Parameter OrgId []:

## Domain Name for the shortener.
Parameter CustomDomainName []:

## Shows you resources changes to be deployed and requires a 'Y' to initiate deploy
Confirm changes before deploy [y/N]: 

## SAM needs permission to be able to create roles to connect to the resources in your template
Allow SAM CLI IAM role creation [Y/n]:

## Save your choice for later deployments
Save arguments to samconfig.toml [Y/n]:

SAM will then deploy the AWS CloudFormation stack to your AWS account and provide required outputs for the included client.

After the first deploy you may re-deploy using sam deploy or redeploy with different options using sam deploy -g.

Cleanup

Open the CloudFormation console
Locate a stack named URLShortener
Select the radio option next to it
Select Delete
Select Delete stack to confirm

*Note: If you opted to have access logs (on by default), you may have to delete the S3 bucket manually.
