Strapi is an open-source headless CMS based on Node.js, allowing developers to build backend APIs faster with efficiency and customizability advantages. Remix, a server-side rendered framework, can consume generated API endpoints from Strapi. Next.js is another popular React framework for server-side rendering, but its difference from Remix is minimal. To set up Strapi, create a project folder, install the CMS using `npx create-strapi-app`, and model the backend content with Strapi's Content-Type Builder. Remix can access this collection by generating an API token to communicate with Strapi. The API token will be used to handle exemptions when connecting to the Strapi backend API. To test if it works as expected, ensure that the Remix development server is up and running using `npm run dev`. This will serve your application on `http://localhost:3000`, allowing you to access the content of each specific blog post by clicking on any post on the home page.
