Let's build our own URL Shortener with NestJS and Redis

Creating a URL shortener using NestJS and Redis involves transforming long URLs into compact links by assigning unique identifiers stored as key-value pairs in a Redis database. This project demonstrates the practical application of these technologies, emphasizing the use of Upstash Redis for managing data and NestJS for structuring the application with a focus on dependency injection and decorators for abstraction. The URL shortener allows users to generate shortened URLs and retrieve the original links via unique path keys, enhancing the ease of sharing and managing URLs. The guide walks through setting up the environment, integrating necessary modules, and implementing methods to set, retrieve, and manage shortened URLs, showcasing the developer-friendly features of NestJS and the efficiency of Redis in building scalable, real-world applications.
