This proof-of-concept demonstrates the use of Netlify's serverless AWS Lambda functions to create a custom URL shortener that can be hosted on one's own domain. The system allows users to submit new destination URLs and receive a new shortcode URL in return, with the ability to generate unique shortcodes, ensure uniqueness, and sanitize submitted URLs. Serverless Lambda functions are used to automate the process, handle form submissions, and provide real-time redirects to the user. The project showcases how Netlify's features can be combined to create a useful tool that can be customized further with additional functionality.
