The Most Minimalist Next.js TODO app

The article outlines the process of building a minimalist serverless TODO application using Next.js, without relying on any database connections or extra dependencies beyond Next.js itself. It emphasizes the use of REST API due to its stateless nature, making it ideal for serverless environments, and utilizes Upstash Redis as the database backend accessed via REST. The project setup involves creating a Next.js app and an Upstash Redis database, with three API endpoints for listing, adding, and removing TODO items. The application employs React hooks for state management and is designed to run and deploy seamlessly on Vercel, leveraging serverless functions to handle API requests. The article also highlights the importance of keeping the database token secure in environment variables and suggests maintaining both serverless functions and the Redis database in the same region for optimal performance.
