Angular 4 node_modules

Wow ... I'm planning on building my Angular 4 App this weekend.  I am working through the tutorial and just had a moment of horror ...

217 MB for a JavaScript Framework?!  You've got to be kidding me.  

There are over 700 subdirectories under node_modules. 

Now, I did take a look at the HTML generated and it does not appear to reference node_modules.  I am going to see if I can get away with NOT deploying it.
