Ionic Nav Routing API Proposal

app.js

angular.module('myApp', ['ionic'])

.config(function($ionicNavProvider)) {
  $ionicNavProvider.url('/contact/:contactId', {
    templateUrl: 'contact.html',
    controller: 'ContactCtrl',
    extra: {}
  })
})

.controller('MyCtrl', $scope, $ionicNavDelegate) {
  var nav = $ionicNavDelegate($scope);
  
  // Explicit routing
  $scope.openMessage = function(message) {
    nav.push('message.html', 'MessageCtrl', {
      message: message
    });
    
    // Pushed with a named animation, OR pass in a function or animation object which controls the animation
    nav.pushWithAnimation('message.html', 'MessageCtrl', 'slide-up', {
      message: message
    });
    
    
  }
});
