gpull is a simple wrapper for git pull, with the addition that it also watches for any changes to package.json or package-lock.json and if detected will automatically run npm i afterwards.
Now you don't have to worry about your dev environment malfunctioning when someone else makes updates!!
cargo build --release will create ./target/release/gpull
I recommend putting the gpull binary somewhere on your local $PATH and creating an alias like alias gpl='gpull' so you can easily run gpl in whichever repo you want.
