Modules are an essential part of any non-trivial JavaScript application which requires more than a single code file. And while modules have been a standard part of JavaScript Since ES2015, it has taken browsers a while to support them. During this time, developers have turned to tools such as webpack, Rollup, and Browserify. These solutions have completely changed the way we write and deploy our web applications. But now that browsers are starting to support ES2015 modules, it’s a good time to examine if these solutions are still relevant. In this session I will show why built-in browser support for ES2015 modules is a game changer, and how, when combined with additional new JavaScript features and network protocols, it can revolutionize the way we package and deploy web applications. I will explain in detail the benefits and limitations of browser support for ES2015 modules and highlight their advantages over existing JavaScript packaging solutions.
