URL shortener for AWS Lambda and S3
A lightweight URL shortener built with the Serverless Framework using AWS Lambda and S3. Each URL redirection is stored as an S3 object with the
Website-Redirect-Locationmetadata key set to the forwarding web address. AWS Lambda is used to create an API to save these objects. The website is served from the same S3 bucket.
Head on over to the Serverless Framework docs and run through their quick-start guide. It’s mentioned in there as part of your setup, but be sure to install the AWS CLI and configure your AWS credentials. Then run
npm installto get the NPM dependencies for the project.
Create Route 53 hosted zones for both the API and website.
Create a copy of .env.example for each "stage" that you wish to deploy to (e.g .env.staging, .env.production) and then customise each configuration file as appropriate for your setup.

npm run deployto deploy the API and website to AWS. The resources defined in serverless.yml will be automatically instantiated using CloudFormation. Prefix with the stage you want to deploy (e.g.
STAGE=production npm run deploy).
Architecture based on serverless-aws-static-websites:
npm run buildto build the template with appropriate template variables.
npm run deploy:clientto deploy the website using the AWS CLI.
You can add a
?vanity=query string parameter to the homepage to specify a vanity (custom) shortcode instead of a randomly-generated one. If the name is already taken, a random one will be used instead.
