Building a survey app with Upstash Redis and Next.js

Redis, traditionally perceived as a tool for caching and message brokering, is explored as a primary database in a full-stack web application built using Next.js and Upstash's serverless Redis. The application, designed to collect user feedback via an online survey, demonstrates the strong performance and minimal latency benefits of Redis as an in-memory database. The tech stack includes Next.js for both frontend and backend development and Upstash Redis for data storage, emphasizing the ease and cost-effectiveness of serverless architecture. Survey data is stored and retrieved using Redis keys and sets, illustrating a different approach from SQL databases. The project highlights the advantages of Upstash's persistent Redis databases, such as simplicity in setup and low per-request pricing, while also providing a hands-on example of designing and implementing a scalable application with Redis as the primary storage solution.
