Error: Cannot find module html

Question

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 require (module.js:380:17)
  at new View (C:\Users\fr\node_modules\express\lib\view.js:42:49)
  at Function.app.render (C:\Users\fr\node_modules\express\lib\application.js:483:12)
  at ServerResponse.res.render (C:\Users\fr\node_modules\express\lib\response.js:755:7)
  at allClients (C:\Users\fr\node_modules\apps\chat.js:13:7)
  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

Do not place your code inside node_modules! The folder contains dependencies and should be inside your application's folder. — jgillich, Apr 19 '13 at 18:43
I thought that all my modules files must be in the root folder ? — Cxodael, Apr 19 '13 at 18:47

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')));

This tells 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)

I have used it for a chat 2 years ago ! I liked it ! – Cxodael Apr 19 '13 at 19:39
`app.use(express.static(path.join(__dirname, 'public')));` This might be a little confusing to some people. Don't point the browser to the `/public` directory. Point the browser to the `/` root directory and it will find the static files located in the `/public` directory. – DR01D Jan 07 '18 at 17:37

Simple way is to use the EJS template engine for serving .html files. Put this line right next to your view engine setup:

app.engine('html', require('ejs').renderFile);

Thanks for a short answer! All I needed was that single line of code to fix the error. – Lukasz Wiktor Jul 17 '17 at 19:01

Install ejs if it is not.

npm install ejs

Then after just paste below two lines in your main file. (like app.js, main.js)

app.set('view engine', 'html');

app.engine('html', require('ejs').renderFile);

This is what i did for rendering html files. And it solved the errors. Install consolidate and mustache by executing the below command in your project folder.

$ sudo npm install consolidate mustache --save

And make the following changes to your app.js file

var engine = require('consolidate');

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

And now html pages will be rendered properly.

Use

res.sendFile()

instead of

res.render().

What your trying to do is send a whole file.

This worked for me.

I think you might need to declare a view engine.

If you want to use a view/template engine:

app.set('view engine', 'ejs');

or

app.set('view engine', 'jade');

But to render plain-html, see this post: Render basic HTML view?.
