How to Handle an Empty Route with a Trailing Slash in Backbone Routing?

How to Handle an Empty Route with a Trailing Slash in Backbone Routing?

While I am aware of the potential SEO issues that come with duplicate content, my project is not currently focused on that aspect.

Looking at my backbone router configuration, here it is:

routes: {
    "": "startOrder",
    "order/:orderNumber/:stepName": "getOrder",
    "order/:orderNumber/:stepName/": "getOrder"
},

You may notice that the second and third routes direct to the same destination.

The challenge arises when a user enters a URL that ends with just a "/" character. In such cases, I would like it to trigger a distinct function (and then remove the slash), but instead, it always matches with the blank route. As a result, this causes issues later on due to the presence of an unnecessary slash in the URL.

Is there something crucial that I seem to be overlooking in this scenario?

Now, it is possible to include a slash within parentheses as an optional part of the route:

With Backbone.Router.extend({
  routes: {
    'order/:orderNumber/:stepName(/)': 'getOrder'
  },
  // ...
});

This information comes from a detailed discussion about using slashes at the end of Backbone routes.

However, it's worth noting that in order to prevent multiple URLs being recorded for your pages, it is recommended to remove the trailing slash in paths within Apache or other server configurations.

Instead of defaulting to no match, it seems like you're always landing on the blank route. This may be because you forgot to initialize Backbone.history.start with { pushState: true }. Ensure you start it with

Backbone.history.start({pushState: true });

If you need a route that captures anything ending with a /, consider using a *splat and concluding it with a /. Here is an example setup:

routes: {
    "": "startOrder",
    "order/:orderNumber/:stepName": "getOrder",
    "order/:orderNumber/:stepName/": "getOrder",
    "*dummy/": "endsWithSlash"
}

Remember to place the dummy route last in the list. Otherwise, the dummy route will take precedence over your order route with a trailing slash.

The specified paths are automatically translated into regular expressions internally. You have the option to provide custom regular expressions when using the route method, allowing for more flexibility in defining your routing rules.
