Watch This!
What if we didn’t have to run a command at all? I mean, we would have to run grunt every time we wanted to make a change to one of our files before we could test that change on Chrome. What if Grunt could just magically package our extension each time we made a change? Although it’s not exactly magic, Grunt can do exactly that with a plug-in called grunt-contrib-watch. When we downloaded and installed our other plug-ins, we added them to package.json and then ran npm install. This time, we are going to download and install first, and then (automatically) add a new line to package.json. See Listing 4.10.
