Not too long ago I wrote a simple Chrome Extension for my brother-in-law to help him quickly fill out some online forms for work. While I learned the basics of Chrome Extensions, I was hoping to find some kind of super-simple example that I could use as a starting point, but wound up just doing everything from scratch.
After I finished the project, I decided to create my own boilerplate.
It is very simple - it only contains elements for a content script, and includes jQuery. Clone the repo, change the name of the extension in the "manifest.json" file and get to coding in the "main.js" file. Have fun!
