My index.html file has this:

<input name='qwe'>
{{qwe}}

I want that {{qwe}} to be sent literally, i.e. not replaced by variables populated by the server.

How should I do that? I was thinking in this pseudo code:

app.get('*',function(req,res){
  fs.read('index.html',function(data){
    res.send(data)
  })
})

But I suppose I don't know how is this usually done. Maybe I have to use a predefined Express.js template engine:

app.engine('html', ...)

But I don't know what part of the documentation to read. I also took a look at consolidate.js, but all of these templates, seem to be, "template engines", do I really need a template engine?

I want to send a file as it is.

By the way, I am doing all of this because I want to work with Angular.js, but for experimentation purposes I am not using MEAN, I assume MEAN has to do something like this.

Update

I am trying this:

app.get('*',function(req, res){
  require('fs').readFile('views/index.html', 'utf8', function(err, data){
    if(err) throw err;
    res.send(data);
  })
  // res.sendfile('views/index.html');
});

But file is downloaded and not rendered, any advice? I suppose I have to set Content-Type or another header?
