[nodejs] Load Html file.

That would work if you want to send out that one file no matter what
request comes in. I doubt that is what you want to do.

If it's done during app initialization you should load it synchronously.

Pedro,
Yes, it's done during app initialization, how can i do this?? I´m
begginer with node, can you explain more details about it?

Mark,
Ii want to do what Pedro said.

cheers.

You can use readFileSync<http://nodejs.org/api/fs.html#fs_fs_readfilesync_filename_encoding>

var http = require('http'),
fs = require('fs');
var html = fs.readFileSync('./index.html');

http.createServer(function(request, response) {
response.writeHeader(200, {"Content-Type": "text/html"});
response.write(html);
response.end();
}).listen(8000);

I've to create a server just to read a file??? I'm getting trouble with
this, because always when i call a URL i create a server, because i put
this inside of s function:

No, of course not. But your original code indicated that you want to read a
file and then serve it. That's what Jose's code does - it reads the file
(in one line of code), and then creates a server that serves the contents
of that file each time a new request is made.

No, the server is created once, and the (anonymous) function that was
passed to createServer is called each time a request is handled. That
function sends back the contents of the file that was read earlier.

It might be a good idea for you to work through one or two tutorials on
Node, so that you get a clearer picture of how it all works. You'll find
pointers to several of those in the archives of this list. Those at
http://www.nodetuts.com/ and http://www.nodebeginner.org/ seem to be fairly
frequently referenced here.

Thanks Martin,
I will read the tutorials.

cheers.

Ok, it´s created once, but, if there is another server that was created? I
have to put the same port? Another thing interesting, when i put the same
port or any other port in listen() is that when i reload in the first time
my view is rendered normally, on the second time my view lose the css and
on the third time i lost the contact with the server, but when i don´t put
anything in listen, the view render normally, why? I'm reading these
tutorial, understanding a bit the node, but this is really curious for me...

I started with nodebeginner, i'm really enjoying, thanks again.

You haven't mentioned CSS before, and you haven't shown us the HTML
content, so it's a little hard to know what's going on. However, I should
point out that you are responding to *every* request to your server with
the contents of the HTML file. So if your CSS URL is also pointing to the
same server, it's going to retrieve HTML content and not CSS content. That
would not be good! You would need to look at the request, in your server,
to determine what you should be sending back. Again, the tutorials should
help you understand this better.

* *Sorry, i'm doing a mcv app in node, i have a layout, so all i do is to
put the content in this layout, so, if the url is "test", this call
"test_controller", that render "layou/layout" and call "layout_controller"
where is send to a function "layout" the object from "test_controller", see:

LayoutController.layout = function(obj)
{
var http = require('http'),
fs = require('fs');
var html = fs.readFileSync('./app/views/'+ obj.__action+'/'+obj.fileName);
http.createServer(function(request, response) {
response.writeHeader(200, {"Content-Type": "text/html"});
response.write(html);
response.end();
}).listen();
obj.content = html;
obj.render('layout/layout');
}

As can be seen, this function read in on single place every different obj
that comes here, but, as you can see, the layout is all the page with css
and javascript, it's always static, only the content changes. So, as you
can see again, the listen obj is empty, and it's works perfectly, but when
i put some port happens what i said before.

Since you're already working within a framework, it is extremely unlikely
that you'll either need or want to create another server, especially inside
a controller. What you describe above sounds like the routing part of the
existing server, so you should be working within that.

I see now that you mentioned Locomotive in your original message here. I'm
not familiar with that, but I see that it has a Google Group of its own.
I'd suggest you ask in that group how you should be addressing your problem
within the context of that framework. You'll likely get more appropriate
responses there, from people who know the framework you're using.

Ok, i just posted in there, thanks again.

hey guys,
i just finished or almost, and i didn't need to use any other module, and
i discovered some thing that maybe be useful to some people, here:

LayoutController.layout = function(obj)
{
var fs = require('fs');
*var html = fs.readFileSync('./app/views/'+ obj.__action+'/'+obj.fileName);*
obj.content = html;
//acessando a view especifica do controller layout
obj.render('layout/layout');
}

I don't need to create a server just to read, i'm using this to generate my
main layout and is working very well, i don't know if this is the right
way, but i don't think that exist any "right way", for me, this is working
in a way that i need...
