因為不想廢話，這裡就不解釋什麼是WebSocket了XD，進入正題

這裡直接使用Github上的websockets/ws項目，它直接使用了express做為項目，所以我們也一起跟著用吧XD

連結在這 https://github.com/websockets/ws

這裡我只寫我做的結果，所有的內容會放到github上，也會給上連接

Server的code

假裝Server有一直在傳輸信息所以使用setInterval 代替 

Client的code

執行server.js查看效果

Server console

Client page

Client console

<% %>流程控制標簽
//例
<% var user.name = 'bruce - huang' %>
<% if(user.name !== null) { %>
<div>hi <%= user.name %></div>
<% } else { %>
<div>no user name</div>
<% } %>

<%= %>输出標簽（原文输出HTML標簽）
//例
<% var user.name = 'bruce - huang' %>
<%= user.name %>

<%- %>输出標簽（HTML会被浏览器解析）
//例
<%- data.htmlContent %>


<%# %>注释標簽
//例
<%# 我是注解，我不會被秀在源始碼上 %>

-%>去掉沒用的空格
//例
<% var user.name = 'bruce - huang 看己去試吧, 我是不知道他怎知道什麼叫沒用的空格XD' %>
<%= user.name -%>
