Node.js Question

Node.js : Cannot find module html

I have not used Node.js for a long time and never used express. When I started my application, it just returned :

Error: Cannot find module 'html'
at Function.Module._resolveFilename (module.js:338:15)
at Function.Module._load (module.js:280:25)
at Module.require (module.js:364:17)

at callbacks (C:\Users\fr\node_modules\express\lib\router\index.js:161:37)
at param (C:\Users\fr\node_modules\express\lib\router\index.js:135:11)


The error occured when I launched test.html. Here's the code :

var io = require('socket.io');
var express = require('express');

var app = express(),
http = require('http'),
server = http.createServer(app),
socket = require('socket.io').listen(server);

app.configure(function(){
app.use(express.static(__dirname));
});
app.get('/', function(req, res, next){
res.render('./test.html');
});

server.listen(8333);


My path :

node_modules/
express/
socket.io/
apps/
chat.js
test.html


Why ?

EDIT :

This is my new app.configure :

app.configure(function(){
app.use(express.static(path.join(__dirname, 'public')));
});


But it returns :

path is not defined

Answer

I am assuming that test.html is a static file.To render static files use the static middleware like so.

app.use(express.static(path.join(__dirname, 'public')));

What this does is tell express to look for static files in the public directory of the application.

Once you have specified this simply point your browser to the location of the file and it should display.

If however you want to render the views then you have to use the appropriate renderer for it.The list of renderes is defined in consolidate.Once you have decided which library to use just install it.I use mustache so here is a snippet of my config file

var engines = require('consolidate');

app.set('views', __dirname + '/views');
app.engine('html', engines.mustache);
app.set('view engine', 'html');

What this does is tell express to

  • look for files to render in views directory

  • Render the files using mustache

  • The extension of the file is .html(you can use .mustache too)
