So instead, I've created a "common" folder as a peer to each of my project folders and I put my utility.js file in that common folder. Then, in Tizen Studio, I just added the common/js/utility.js file as a "Link to file in the file system" I then had to change my .html file's reference to utility.js from: <script src="js/utility.js"></script> to: <script src="../common/js/utility.js"></script>
But the problem is deployment. It doesn't work. I'm guessing that when the package is deployed to the emulator (or device), it doesn't copy the "common" folder and thus my utility.js is not found.
Is there a better way to do this (reuse common js source code) short of just having my utility.js copied to each project folder?
