What is the best way to incorporate an optional URL within Angular routes using ui-router?

Is it possible to define state with an optional URL in Angular UI-Router?

If so, how can I achieve this functionality?

For instance:

state('test',{
   url:'/list/:id/color?/:color?'
}

In the given example, both "color" and ":color" are optional parameters. The state should be able to handle URLs like:

site.com/list/1

site.com/list/color/red

Answer №1

An upgrade was implemented in the library a couple of years ago, allowing for this specific functionality:

$stateProvider.state("foo", {
  url: "/foo/{foo}",
  params: {
    foo: { value: "bar" }
  }
});

By setting a default value to 'foo', it enables the route to match /foo, /foo/, and /foo/baz. Moreover, even when matching /foo or /foo/, $stateParams will still hold the data { foo: "bar" }
