Question

I’m trying to return a plain javascript if a user access to a given route inside my app. I want to give users the oportunity to include scripts from my site inside theirs, like
this:

<script src="MY_DOMAIN/foo">

If I write:

app.get('/foo', function (req,res) {
  res.end("document.write('<p>Hello</p>'");
});

The returned javascript includes all the layout so the client browser can’t handle it.

Ahy idea?

Thanks in advance

You need to set the content type.

app.get('/foo', function(req, res) {
    res.writeHead(200, {
        'Content-Type' : 'application/javascript'
    });

    res.end("document.write('<p>Hello</p>'");
});
