Grunt connect task and middleware Access-Control-Allow-Origin

Question

I would like to allow access to cross origin calls which I need to be able to perform rest API calls to the server.

My connect grunt task is configured as follows:

Answer 1

Try something like this:

connect: {
  options: {
    port: 9000,
    // Change this to '0.0.0.0' to access the server from outside.
    hostname: 'localhost',
    livereload: 35729,

    // remove next from params
    middleware: function(connect, options) {
      return [
        function(req, res, next) {
          res.setHeader('Access-Control-Allow-Origin', '*');
          res.setHeader('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
          res.setHeader('Access-Control-Allow-Headers', 'Content-Type');

          // don't just call next() return it
          return next();
        },

        // add other middlewares here 
        connect.static(require('path').resolve('.'))

      ];
    }
    },
    },
