Question

Navigate to a different state with ui-router upon entering the page

I am implementing two wizard flows, flow A and flow B, each collecting different sets of information.

    states["wizard"] = {
        abstract: true,
        url: "^/wizard",
        controller: "wizardController",
        templateUrl: "wizard.html"
    };

    states["wizard.input"] = {
        url: "^/input",
        views: {
            "": {
                controller: "wizardController",
                templateUrl: "form.html"
            }
        }
    }
    states["wizard.completed"] = {
        templateUrl: "completed.html"
    };

When a user navigates to /wizard, I need to check if informationB is filled. If not, I want to redirect the user to fill informationB first and then return to /wizard to continue with wizardA.

What is the best approach to handle the redirection when the user navigates to /wizard? And how can I smoothly transition back to /wizard once wizardB is completed?

One idea I have is passing a parameter in the URL for the return from wizardB to wizardA. However, I am struggling to determine the best method for the initial redirect.

Thank you for your help!

Appreciate the info, charlietfl! Using resolve for handling redirects seems like a solid approach. Here's my implementation:

const redirect = (returnState: string) => {
    return ['$q', '$timeout', '$state', 'dataModel', ($q, $timeout, $state, dataModel) => {
        const deferred = $q.defer();
        $timeout(() => {
            if (dataModel.informationB === "") {
                $state.go('wizardB.input', { rs: returnState });
                deferred.reject();
            } else {
                // All good to proceed
                deferred.resolve();
            }
        });

        return deferred.promise;
    }];
}

And in the state configuration:

resolve: {
    redirect: redirect("wizardA.input")
}
