node_modules folder into Dropbox. This is going to take a long time to upload and your actual application changes may not get uploaded when you want.
Fortunately, Dropbox has an option to specify which folders to sync, so its easy to configure the
node_modules folder to remain local.
First of all, ensure that you are using the Dropbox application to view folders rather than in File Explorer. Open the Dropbox preferences, and ensure
Open folders in is set to
Dropbox desktop app.
Next, locate the top level folder for your project (the one that contains
node_modules), right click and select
Open In Dropbox.
Within the Dropbox application, right click on the
node_modules folder and select
Don't sync to dropbox.com
You'll now find syncing to Dropbox much faster.
