I am developing my first simple app in Dynamics 365, and one of my main pieces is a Web Resource that involves a lot of tweak-save-test-repeat workflow. Up to this point, every time I have made a tiny change to my web resource, I have been deploying it by opening the solution customization settings, navigating to my particular Web Resource, opening it, clicking "Text Editor" button, pasting in my updated Javascript code, and saving/publishing the changes.
This process is tedious, and I would like to find a way to automate it. I have been researching Dynamics 365 deployment tools, and I have found the CRM Package Deployer tool, but from what I can find it requires me to set up an entire deployment package (a giant XML file) comprising my entire customization, rather than the single file I am currently working on. Is there some way to automate deploying a SINGLE FILE with these (or other) tools? Or is it possible to deploy a package with ONLY A SINGLE FILE rather than re-deploying the entire solution's package each time I just change the one file?
