Dynamic port

Maybe if you use multiple projects you want to use dynamic ports, maybe this works:


module.exports = function( grunt ) {

  var server_port_number = 9000;
  grunt.initConfig({
    'http-server': {
      'dev': {
        port: function(){ return server_port_number; },
        ...
      }
    }



  grunt.registerTask('server', function( port ) {
    server_port_number = port == null ? 9000 : port;
    grunt.task.run('http-server:dev');
  });




To assign a port, we just exec:
grunt server:9090
