Web-oriented databases, frameworks like Nuxt and Next.js, and even frameworkless approaches are evolving the Jamstack, but the core principles are more powerful than ever. As the developer community has grown, there’s also been more noise, and we’re even starting to test the boundaries of Jamstack’s best practices. It feels like the right time to both revisit the original vision some of us had five years ago, and look ahead at what the changes in the technological landscape will mean for the future of the Jamstack architecture and the web.

Instead of sending the entire video at once, a video is sent as a set of smaller chunks that make up the full video. This explains why videos buffer when watching a video on slow broadband because it only plays the chunks it has received and tries to load more. In this article, Deven Rathore will build a video streaming app using Nuxt.js and Node.js. Specifically, you’ll build a server-side Node.js app that will handle fetching and streaming videos, generating thumbnails for your videos, and serving captions and subtitles.
