Do not upload node_modules

The node_modules folder includes all the dependencies your project uses, based on your package.json file or any packages added in the Additional Packages section of the Startup tab.

Because this folder can be very large, it may cause problems during upload or when extracting files on the server. It can also result in packages being installed incorrectly for the server’s environment.

For this reason, you should not upload the node_modules folder. The server will create it automatically when it starts.
