Nodejs static files: Using Nodejs to compress js,css static resources

1.[js compression]uglifyjs Source.js-mc-o target.min.js
To compress Angular.js as an example, can compress local variable name, remove useless local variable, blank character, etc., compression ratio is close to 80%, the efficiency is good

2.[CSS compression]sqwish Style.css–strict
Sqwish now appears to be a low compression ratio.
[User_00@localhost ~]$ sqwish style.css--strict
[User_00@localhost ~]$ Ls-lh style.*
-rw-rw-r--1 user_00 user_00 5.8K Dec 10:40 style.css
-rw-rw-r--1 user_00 user_00 5.5K May 4 16:14 style.min.css
