Javascript sdk

It sounds like you're trying to use the Dropbox API v2 JavaScript SDK. That comes with a number of examples that you can try here. There are also instructions on that page for running the examples. 

Did you follow those instructions? Which example are you trying in particular? Also, can you elaborate on what you mean when you say you are "not able to access files in the app folder"? For instance, please share any unexpected error or output.

Thank you for the reply. I downloaded the javascript sdk files and installed on my Mac. However, I want to start the development server i.e. server.js but it throws up an error. See below. I don't think I can move forward if I do not get the node server up and running.

    throw Error('[rollup-endpoint] File does not exist: ' + options.entry);

To run those examples, you'll need to follow the instructions here for setting that up. Did you do so? What output did you get if so?
