This is just a simple study using nodejs server with expres and web api being consumed by ajax jquery, i'ved focus on back-end.
node-server/prompt-chat.js is a chat using prompt to talk with another person that is running node-server/prompt-chat.js too.
node-server/web-api.js is a web api that response the ajax of my web/index.html, is such more easy to use with more than one person because don't have to edit nothing.
