Obtain the templateUrl using the ui-router functionality

Question

Obtain the templateUrl using the ui-router functionality

Perhaps the title is a bit unclear.

I am currently working on two Angular apps nested within each other. Each has its own router created using `ui-router`. If I call a state that is not recognized by the main router, I would like it to search for this state in the sub-app router to retrieve the corresponding `templateUrl` and `url` for that state.

One solution I considered was creating a service with a parser that could extract the necessary data from the file. However, I believe there may be a better option available. That's why I am curious to know if there is a specific function or method in `ui-router` that can help me achieve this. Based on what I have read in the `ui-router` documentation, it does not seem so :/

Please feel free to request more details or suggest another solution that aligns with my objective :)

To implement this functionality, utilize dynamic parameters within your $stateProvider configuration specified in your sub-module. If there are anchored routes in the main module and a match is found, ui-router will fetch the corresponding template. In case no absolute route/url match is found, ui-router will fallback to your parameterized route, as shown below:

// anchored
$stateProvider
  .state('mainAppState', {
    url: '/anchored',
    controller: 'myCtrl'
 })

// sub module
 .state('subAppState', {
    url: /:parameter
    resolve: { // use the resolve and $stateParams to get some parameter with which you can make a request to your API }
    templateProvider: { // inject a service and use it to call your backend }

You can access the parameter passed to $stateParams, which is then passed to your resolve block functions to retrieve or process data from $stateParams. This information can be utilized by templateProvider to generate a meaningful fallback URL. The templateProvider function receives all resolves and waits for them to resolve before execution.

This approach allows you to capture unmatched URLs from the main app into the sub app. I hope this explanation clarifies the concept.

Additionally, remember to properly define your templateProvider function dependencies using .$inject = [ ... ] if you plan on obfuscating your JavaScript during the build process. Failure to do so may result in an unknown provider error. Alternatively, you can use /* @ngInject */ as a workaround, which has proven effective in my experience.
