Implement a mandatory parameter in the URL route using ui-router

My Angular routing configuration using ui-router is quite simple:

$stateProvider

    .state("master", {
        abstract: true,
        url: "/{tenantName}"            
    })

    .state("master.home", {
        url: "",
    })

    .state("master.login", {
        url: "/login"
    })

I want to ensure that if there is no parameter in the URL, it does not match any state and instead goes to a default state. However, I'm facing two challenges:

  1. The 'master.home' state currently matches the URL with just the domain (e.g., domain.com) when I want the parameter to be mandatory (e.g., domain.com/hello). The only solution I've found involves using a non-empty regular expression, but I'm hoping for a better approach.

  2. I'm unsure how to define a proper default state. It appears that the only option is to create a state with a "" URL (once issue 1 is resolved) and then use the .otherwise method to redirect to that state's URL.

Answer №1

you have the option to specify a default state

app.config(function($urlRouterProvider){
    // If no matching URL is found in your configuration, 
    // the "otherwise" method will redirect the user to the specified URL
    $urlRouterProvider.otherwise('/index');

    // You can also use a function as a parameter for more complex routing logic
    $urlRouterProvider.otherwise(function($injector, $location){
        ... advanced code here...
    });
})
