Node-dev is a development tool for Node.js that automatically restarts the node process when a file is modified.
In contrast to tools like supervisor or nodemon it doesn’t scan the filesystem for files to be watched. Instead it hooks into Node’s require() function to watch only the files that have been actually required.
This means that you don’t have to configure any include- or exclude rules. If you modify a JS file that is solely used on the client-side but never run on the server, node-dev will know this and won’t restart the process.
This also means that you don’t have to configure any file extensions. Just
require a .json file or a .ts script for example and it will be watched.
Automatically.
Just run node-dev as you would normally run node:
node-dev server.js
--respawn - Keep watching for changes after the script has exited
