This is a step-by-step guide on how to create a static portfolio site using Contentful as the content manager, Next.js for data display, and Netlify for hosting. The author starts by setting up their content types in Contentful and then creates a new project with Next.js to display the data. They use a script to fetch the data from Contentful and write it to disk, and then create React components to display the data. After configuring the site, they deploy it to Netlify using a build hook to automate the deployment process. The final step is to set up a webhook in Contentful to push updates to Netlify, allowing for seamless integration between the platforms.
