Dynamic parameters with ui-router - angularjs

I'm developing a search app with angular using ui-router.
Requirements:
The search form has too many fields and all have to be optional.
Users should share with another users the URL that display the page with the result list. (So I need to use querystring)
So I could have urls like
path/to/url/list?p=123&v=876
path/to/url/list?c=yes&a=true&p=123
path/to/url/list?z=yes&c=yes&a=true&p=123
path/to/url/list?z=yes&v=876&a=true&p=123
And endless combinations. I know that I can use $location.search() to get all params in json format. That is great! but the question is How can I define the url state with ui-router? Define explicitly all params in the url is not an option. I have read many post but I didn't find a concrete answers.

If you're getting parameters from $location you don't need to define them in state explicitly.

I think, the best way is to use 'resolve' property of $stateProvider configuration:
$stateProvider.state('mystate', {
// Some code here
resolve: {
queryData: ['$location', ($location) => {
$location.absUrl(); // Contains your full URI
return true;
}]
}
});
It's kind of initialization. After that, ui-router will cut URI, but you will store needed data. This case also works fine, when user passing URI directly in browser address input.
Also you can try to set $urlRouterProvider with $urlMatcher for this purposes, but it will be more difficult.

How to pass query string parameters through URL

I am using this:
$state.go("/path/to");
I want to do this:
$state.go("/path/to?param=myParam");
But this is not working.
I have tried:
$location.path("/path/to?param=myParam");
$location.path("/path/to").search({param: "myParam"});
Both of them actually change the url but not updated the angularjs app - since this is not connected to the actual router.
How can I pass query string parameters using AngularJS ui router?
Note I know I can pass a full url path like this:
/path/to/param/myParam
But I need in this case that it will be query string params.
According to the documentation $state.go takes another parameter that you can use to pass query string.
$state.go("/path/to",{param:myParam});
Url config use like this
.state('path/:param', {
url: '/path/:param',
templateUrl: 'views/path.html',
})
you get value in controller use to $stateParams
I don't know why, but angularjs ui router is very tedious vs the regular ngroute made by Angular team. The reason I am using ui router is just because that it supports for lazyload of the view.
Anyway, this is the solution I was found - using $state.go and $location.path both:
$location.path(`/path/to`).search({param: "myParam}});
$state.go(`/path/to`);
This can be wrapped for easy use:
module.exports = (path, qsObj) => {
if (qsObj) {
$location.path(path).search(qsObj);
}
$state.go(path);
}

AngularJS: get url path without routeParams

Take this route for exmaple
when('/coordinator/editApplications/:appId', {
templateUrl: 'assets/app/templates/coordinator/editApplications.tpl.html',
module: "/coordinator",
})
Without using regular expressions, is there a property/method available in Angular that will allow me to get the path value with the parameters stripped off?
The value I would want for this example would be /coordinator/editApplications
This needs to be be universal because there could be multiple params or differently named params. I can't find anyway on the $route or $location to get this value as they all seem to contain the params.
Again, I know i can use regExp to do this but I want to avoid that. I also don't want to just add another property to the route w/ the non-param url value.

Angularjs: Can i have one route with multiple views?

Consider a certain route let's say myapp\profile
which has two modes (buyer/seller)
What i would like to achieve is:
keep the same route url for both modes
Alternate the view with different HTML files (lets say buyer.html, seller.html), of course each view has it's view model.
Sharing some logic between the two modes.
I would like to have a controller/logic to each mode
What i already considered:
Thought about using ui-router's sub states, but I dont want to change the url.
Thought about creating this 'profile' route and while navigating to it, figure the mode (buyer/seller), and then $state.go to a new state (but again, i would like to keep same route name at the end so it's not ok)
Ideally thought i could navigate to my shared controller and then render the correct view and controller, but this idea kinda messed up me.
Could you share what is a clean way of doing this?
most use cases
Normally, in order to dynamically select a template for a state, you can use a function:
state = {
.....
templateUrl: function($stateParams){
if ($stateParams.isThis === true)
return 'this.html'
else
return 'that.html'
}
}
but...
Unfortunately you can't pass other injectables to the templateUrl function. UI.Router only passes $stateParams. You don't want to alter the URL in anyway so you can't use this.
when you need to inject more than $stateParams
But you can leverage templateProvider instead. With this feature, you can pass a service to your templateProvider function to determine if your user is a buyer or seller. You'll also want to use UI.Router's $templateFactory service to easily pull and cache your template.
state = {
....
templateProvider: function($templateFactory, profileService){
var url = profileService.isBuyer ? 'buyer.html' : 'seller.html';
return $templateFactory.fromUrl(url);
}
}

Force ui-router to reload on querystring changes

I have a state defined something like this:
$stateProvider.state("app.search", {
url: "/search?q",
templateUrl: "App/Search.html",
controller: "SearchController as vm",
});
When I want to navigate to the search page and specify a search term, I can do something like this:
$location.path("search").search({ q: "stuff" });
Which effective resolves to a url along the lines of #/search?q=stuff. If I then change the search term to "things", the search page correctly reactivates and searches as expected.
However, I'd like to be able to specify "random" querystring parameters which have not been defined in my url, and then have those parameters also reload the state. (Note: this is why I'm using $location.path instead of $state.go to change the URL). So for example, if I was searching for food, my URL may be:
#/search?q=stuff&type=food
And then I may be filtering on spice levels, which may change the URL to:
#/search?q=stuff&type=food&spice=medium
(etc).
The problem though, is that since I haven't defined all the other query string parameters (type and spice in this example), ui-router doesn't reload my page.
I can't use $state.go with { reload: true } because it ignores the unspecified parameters.
Is there a way I can trigger a page reload using "unspecified" querystring parameters? This post suggests I can make the route /search* but that doesn't appear to work for me.
I haven't found a nice way to do this yet with ui-router. If you're willing to sacrifice your integrity a little bit you could utilize an alternate format for your query params. You can use a single http url query param object and list all your criteria using a custom format.
e.g.
/search/q?stuff:type=food:spice=cinnamon
The route setup would look like:
$stateProvider.state("app.search", {
url: "/search?q",
templateUrl: "App/Search.html",
controller: "SearchController as vm",
});
and to navigate with the extra parameters:
$state.go('app.dashboard', { q: 'stuff:type=dessert:spice=cinnamon'});
to access the parameters on the route:
$state.params.q
You can then just parse out the 'stuff' value and then each name/value pair that was passed in.
PS> I'm not sure whether the colon (:) separator is valid but it was used to illustrate the proposed idea.

How to prevent Angular from turning URL hash into a path

I have an angular app with a number of links. Clicking each link displays a particular set of data. I would like each link to set a hash in the URL, like http://foo.com/bar#item1, and I'd also like to show the page with the particular set of data displaying when that URL with the hash is accessed directly.
I was hoping to do it by reading / manipulating the $location.hash(), but as soon as I inject $location into my controller, the #item1 in the URL changes to #/item1. Is there a way to prevent Angular from doing this, and what's the best way of setting up what I described?
You could pass parameters in the routes /bar/item1, catch it with $routeParams and if exist make $location.hash().
"controller"
var anchor = $routeParams.anchorBottom;
if(anchor){
$location.hash(anchor);
$anchorScroll();
}
"link to section"
$location.path('/heart/bottom');
"route"
.when('/heart/:anchorBottom',{
You could see this running here.
