Using this watcher Parcel watches every file in your project root (including all node_modules). To support an optimal caching and development experience Parcel utilizes a very fast watcher written in C++ that integrates with low-level file watching functionality of each operating system. hot ) = require ( 'http-proxy-middleware' ) module.hot is only available in development, so you'll need to check that it exists before using it.

This will prevent the page from being reloaded, and instead apply the update in-place. If you’re not using a framework, you can opt into HMR using the module.hot API. This is also true when using a framework with HMR support built in, like React (via Fast Refresh), and Vue. This means that application state can be retained as you change small things in your code.ĬSS changes are automatically applied via HMR with no page reload necessary. HMR improves the development experience by updating modules in the browser at runtime without needing a whole page refresh. By default, Parcel fully reloads the page, but in some cases it may perform Hot Module Replacement (HMR). open safari.Īs you make changes to your code, Parcel automatically rebuilds the changed files and updates your app in the browser.

You can override this to specify that only connections from certain hosts should be accepted. -host – By default, the dev server accepts connections on all interfaces.The PORT environment variable can also be used to set the port. -p, -port – Overrides the default port.The dev server supports several options, which you can specify via CLI options: After Parcel starts, the location where the dev server is listening will be printed to the terminal.

By default, it starts a server at If port 1234 is already in use, then a fallback port will be used. Parcel’s builtin dev server is automatically started when you run the default parcel command, which is a shortcut for parcel serve. Parcel includes a development server out of the box supporting hot reloading, HTTPS, an API proxy, and more.
