Speed up Strapi Apps with Caching

This guide details the process of implementing caching in a Strapi application using Upstash Redis to enhance performance by reducing response times for frequently accessed data. The process begins by creating a Strapi application, setting up content types such as a "Course" with fields like Title and Description, and configuring the application to be publicly accessible. To add caching, the strapi-plugin-rest-cache package is installed alongside Redis dependencies, and configurations are adjusted in the Strapi project to connect with a Redis database created on Upstash. The guide emphasizes the performance benefits of caching, noting that subsequent data requests are faster due to stored responses in Redis, and highlights the automatic cache management feature that updates caches with content changes. Additionally, manual cache purging can be performed through the Strapi admin panel if needed. The guide concludes by celebrating the optimization achieved and encourages further development of more complex content types or caching strategies.
