| Description | This article explores how to create dual-mode, cross-runtime JavaScript packages that are compatible with both ESM and CommonJS, as well as different runtimes like Node.js, Deno, and browsers. It highlights the benefits of dual-mode packages, such as broader compatibility, seamless transition, and reduced maintenance. It introduces the concept of cross-runtime packages and discusses the two main approaches for creating these packages: the Deno-first approach and the Node-first approach. | Refraction.dev offers a comprehensive suite of features designed to streamline various coding tasks.
