When Chrome developer Jake Archibald called 2016 “the year of streams”, his prediction may have been premature. With the release of Node.js 18 and the new Web Stream API his prediction may finally be coming true (though 6 years late). Web Streams have always been among us, browsers use streams when receiving assets like HTML or video, but the underlying API’s remained mostly opaque to us as developers, until now. The Web Stream API can put a lot of power in your hands as a developer, making it easy to read and even transform large datasets, video files, images, etc… In this session I am going to introduce you to the concept of streams, walk you through the Web Streams API and then show you how to build your own streaming server with a custom stream transformer to process a large (fun) dataset.
