AngularJS ui router passing data between states without URL
I am facing this problem of passing data between two states without exposing the data in the url, it's like user cannot really directly land on this state.
For example. I have two states "A" and "B". I am doing some server call in state "A" and passing the response of the call to state "B". The response of the server call is a string message, which is quite long, so i cannot expose that in the url.
So is there any way in angular ui router to pass data between states, without using url params ?
We can use params , new feature of the UI-Router:
API Reference / ui.router.state / $stateProvider
params A map which optionally configures parameters declared in the url, or defines additional non-url parameters. For each parameter being configured, add a configuration object keyed to the name of the parameter.
See the part: " ...or defines additional non-url parameters... "
So the state def would be:
$stateProvider
.state('home', {
url: "/home",
templateUrl: 'tpl.html',
params: { hiddenOne: null, }
})
Few examples form the doc mentioned above:
// define a parameter's default value
params: {
param1: { value: "defaultValue" }
}
// shorthand default values
params: {
param1: "defaultValue",
param2: "param2Default"
}
// param will be array []
params: {
param1: { array: true }
}
// handling the default value in url:
params: {
param1: {
value: "defaultId",
squash: true
} }
// squash "defaultValue" to "~"
params: {
param1: {
value: "defaultValue",
squash: "~"
} }

Here is an example of a state definition:
$stateProvider
.state('home', {
url: "/home",
params : { veryLongParamHome: null, },
...
})
.state('parent', {
url: "/parent",
params : { veryLongParamParent: null, },
...
})
.state('parent.child', {
url: "/child",
params : { veryLongParamChild: null, },
...
})
This could be a call using ui-sref:
<a ui-sref="home({veryLongParamHome:'Home--f8d218ae-d998-4aa4-94ee-f27144a21238'
})">home</a>
<a ui-sref="parent({
veryLongParamParent:'Parent--2852f22c-dc85-41af-9064-d365bc4fc822'
})">parent</a>
<a ui-sref="parent.child({
veryLongParamParent:'Parent--0b2a585f-fcef-4462-b656-544e4575fca5',
veryLongParamChild:'Child--f8d218ae-d998-4aa4-94ee-f27144a61238'
})">parent.child</a>
Check the example here
The params object is included in $stateParams, but won't be part of the url.
1) In the route configuration:
$stateProvider.state('edit_user', {
url: '/users/:user_id/edit',
templateUrl: 'views/editUser.html',
controller: 'editUserCtrl',
params: {
paramOne: { objectProperty: "defaultValueOne" }, //default value
paramTwo: "defaultValueTwo"
}
});
2) In the controller:
.controller('editUserCtrl', function ($stateParams, $scope) {
$scope.paramOne = $stateParams.paramOne;
$scope.paramTwo = $stateParams.paramTwo;
});
3A) Changing the State from a controller
$state.go("edit_user", {
user_id: 1,
paramOne: { objectProperty: "test_not_default1" },
paramTwo: "from controller"
});
3B) Changing the State in html
<div ui-sref="edit_user({ user_id: 3, paramOne: { objectProperty: 'from_html1' }, paramTwo: 'fromhtml2' })"></div>
