Allowing CORS (Cross-Origin Resource Sharing) requests from grunt server

gistfile1.js

 //Allowing CORS (Cross-Origin Resource Sharing) requests from
 // grunt server, put this into Gruntfile.js
 grunt.initConfig({
    connect: {
      livereload: {
        options: {
          port: 9000,
          hostname: 'localhost',
          middleware: function (connect) {
            return [
              function(req, res, next) {
                res.setHeader('Access-Control-Allow-Origin', '*');
                res.setHeader('Access-Control-Allow-Methods', '*');
                next();
              },
            ];
          }
        }
      }
    }
  });

I only get a:
Cannot GET /
with those settings. Any idea on what to do?

Same for me...

Thank you for the tip. I ran into the same problem as my predecessors.

I think, the configuration has changed in newer versions. With the following code, I got it to work:

grunt.initConfig({
  connect: {
    livereload: {
      options: {
        port: 9000,
        hostname: 'localhost',
        middleware: function(connect, options, middlewares) {
          middlewares.unshift(function(req, res, next) {
              res.setHeader('Access-Control-Allow-Origin', '*');
              res.setHeader('Access-Control-Allow-Methods', '*');
              next();
          });

          return middlewares;
        }
      }
    }
  }
});

It didn't work for me, however, I found the answer here
gruntjs/grunt-contrib-connect#150
hope it helps !

not working for me either : Cannot GET / is the only response
