The article introduces Dynohot, a node.js loader that implements hot module reloading (HMR). HMR allows modules to be updated without restarting the application. Unlike other HMR solutions like Webpack and Vite, Dynohot is designed specifically for server-side apps. By using the experimental node.js loader API and adding the --loader dynohot flag, developers can enable HMR in their projects. It is important to note that the project must be using proper JavaScript Modules and have the type: module set in the package.json file. Dynohot also supports TypeScript and provides a well-typed import.meta.hot object. The article also mentions some patterns and transformations that can be used with Dynohot. Overall, Dynohot offers an efficient and convenient way to implement HMR in node.js applications.
