Node.js CSS3 not working


Recommended Posts

I am attempting to learn Node.js, I hope someone here knows it.

var express=require('express');
var app=express();
var port=process.env.PORT||3000;

app.use('/assets', express.static(__dirname+'/public'));

I require express and next line create and instantiate a var app then next line I do the same for var port

 

last line I 'believe' I am causing express to look in my public file when I use the var assets in a line of code later, will show line

app.get('/',function(req,res)
	{
		res.send('<html><head>'
			+'<link href=assets/style.css type=text/css rel=stylesheet/>'
			+'<title> 9/3 </title></head><body><h1>Hello World!</h1><h2>'
			+'Using Express to make my life easier</hr></body></html>');
	});

Here I am creating a HTML page for localhost:3000 , because 3000 is the default port as shown above. Everything works save the following line

+'<link href=assets/style.css type=text/css rel=stylesheet/>'

I cannot get the css3 to work yet I 'believe' the link is correct, the word assets in the link tag should be dynamically changed to public causing the NODE.JS server to use the style.css file IE /public/style.css

 

I see no style change at all and when I look at the source code this is the line printed

<link href="/assest/style.css" rel="stylesheet" type="text/css" >

I do not know but I thought it would be localhost:3000/public/style.css below is the CSS

body{color: red;}

which as I said is ni the public folder which is in the same folder as the app.js holding the code in question

 

What am I doing wrong that will not use the CSS?

 

Thanks
