Ways to substitute a single parameter within Vue.js router

We are working on a complex multi-level multi-tenant application, where the hostname is used to identify the 'supplier' account and the customer account is included in the URL structure.

For example, our routes are structured like this:

/:locale/app/:customer_id/invoices

On the webpage, there is a dropdown menu that displays all the customer IDs accessible to the user. The goal is for the user to be able to switch between customers, changing the route from /nl/app/4/invoices to /nl/app/5/invoices, for instance. So essentially, I am looking for a way to instruct the VueJs router to update only one parameter value within the current route.

This functionality also applies to the :locale parameter, where we have a language selector at the top of the page.

I am aware that you can use $router.push with a named route and pass in the current parameters, replacing the ones that need updating. However, this requires naming every single route and knowing the route's name when making an update.

Is there a simpler method to request VueJS Router to "provide me with the current route" and allow me to update a specific parameter?

I have conducted extensive research on Stack Overflow and other platforms but haven't found a satisfactory solution yet...

For achieving this functionality, there is no real need for named routes or manual path creation. The Router's push and replace methods actually support partial patches. You can create a simple reusable function to make it work:

// A function that requires router instance and new params object
function updatePathParams($router, newParams) {

  // Get the current params
  const currentParams = $router.currentRoute.params;

  // Create a new merged params object
  const mergedParams = { ...currentParams, newParams };

  // When no path or name is provided to the router,
  // it will simply try to update the current route with new params or query
  // Everything here is optional.
  $router.push({ params: mergedParams });
}

In your component, you can utilize it like this:

onClickHandler() {
  updatePathParams(this.$router, { locale: 'en-us' });

  // At a later time
  updatePathParams(this.$router, { customer_id: 123 });
}

I have merged the params object with existing values to demonstrate the concept. In reality, not all the params need to be passed. If you only want to change one param such as customer_id, then just do:
$router.push({ params: { customer_id: 1234 } })
. Vue-Router automatically retains the same route while keeping other params (like locale in this case) unchanged.
