1 | # Shield Server
2 | This is a node.js web application that creates shields ( https://github.com/olivierlacan/shields )  to solve this issue: https://github.com/olivierlacan/shields/issues/15?source=c .
3 | 
4 | It uses the shielded library ( https://github.com/cainus/shielded ).
5 | 
6 | It runs on heroku out-of-the-box, but can easily run elsewhere.
7 | 
8 | See also the golang version by @jbowes :  https://github.com/jbowes/buckler .  It probably vastly outperforms this library.
