In this video I break down how a headless CMS works in the simplest way possible, and then I prove it by building a working demo in about 10 minutes. A headless CMS is basically two parts: the CMS (your backend content repository/database) and the “headless” part (accessing that content via an API with no frontend overhead). The whole point is developer freedom — you’re not locked into a specific templating system, and you can use the same content across multiple apps and platforms. To make it real, I spin up a Next.js (React) app and connect it to an independent CMS using Wix Studio’s headless setup. I create a CMS collection (I even generate fields with AI to move fast), configure OAuth by creating a client, then install the Wix SDK + Wix Data packages in the Next.js project. From there it’s genuinely only a few lines of code: create the client, query the collection by ID, and map over the results to render titles/descriptions (and later images) on the page. I also show the key “gotcha” when deploying: don’t forget to add your environment variables (client ID) in Vercel before redeploying. The takeaway: headless CMS is easy, flexible, and perfect for things like blogs, bookings, ecommerce, events, and more.
