Visual Studio Code
Announcing gulp-spsync - A Gulp plugin that syncs local files with a SharePoint site
I have to admit it I have succumbed to Visual Studio Code and now also Gulp tasks, well almost at least. I was working the other day with some display templates and page layouts and needed a more efficient way than uploading the files to SharePoint Online. Open with Explorer could have worked, but since I used a customers Office 365 tenant I did not want to store credentials and do all the required voodoo to get that to work.
