CORS

A simple demo of a few scenarios that use Cross Origin Resource Sharing (CORS).

This is a part of my talk on CORS.

Usage

Client Setup

• Serve client/index.html on port 3000 (http://localhost:3000).
  • The serve package can be used.

Server Setup

• In server run npm install to install all dependencies.
• Run the server on port 5000 (http://localhost:5000) by running npm run start in the server directory.

Proxy Server Setup

• In proxy-server run npm install to install all dependencies.
• Run the server on port 8000 (http://localhost:8000) by running npm run start in the proxy-server directory.
