Running the demo

• Download and install golang
• Clone the repo git clone git@github.com:monmohan/cors-tutorial-practical.git
• Running the Servers
  • Map couple of loopback interfaces to page and apiserver. For example here is my etc/hosts file

     127.0.0.3 apiserver.cors.com
  

  • The servers can be run directly from the source
  • Change to the relevent directory
  • Type go run <filename>

• Follow along the Blogs or play around with the code .
