List heavy deps from a given string - which is an output from the command `du -skh node_modules/*` on your project.

This snippet will show you the dependencies of your project that are heavier than 1M. For that, you'll need the list of all of your deps and their sizes. You can do it by:

$ cd yourProject/
$ du -skh ./node_modules/* >> deps.txt

Go to the file deps.txt and all of your deps will be there. Copy the content, paste on any JavaScript console inside a variable and call the function. Just like that:

const packages = `500K	@algolia
564K	@aws-crypto
 48M	@aws-sdk
6.1M	@babel`

listHeavyPackages(packages)

The output will look like this:

./node_modules/@aws-sdk might be a heavy package: 48M
./node_modules/@babel might be a heavy package: 6.1M
./node_modules/@types might be a heavy package: 1.1M
