The Problem

Need for Default Query Parameters

Imagine you have a page where you want to track all incoming traffic with a specific campaign. You want every outgoing link from this page to carry this information. However, if the page uses components that are shared across multiple pages, adding query parameters directly in each router link can be tedious and error-prone.

The Solution

Fortunately, there’s a straightforward way to append default query parameters to all router links using Vue Router's navigation guards. Specifically, the beforeRouteLeave guard can be utilized to manipulate the route's query parameters right before leaving a component.

Step-by-Step Guide

Here’s how you can implement this solution:

Locate your Component: Go to the Vue component where you would like to add the default query parameter.

Implement the beforeRouteLeave Guard: Add the following code snippet to your component:

Explanation of the Code

beforeRouteLeave: This is a navigation guard that gets called when you are about to leave a route. It provides you with the next route (destination) and gives you control over whether to proceed or not.

next(): This is how you control the navigation. You can either redirect to the modified path or allow the navigation to continue seamlessly.

Final Thoughts

By implementing this solution, you effectively ensure that all router links on the specific page carry your desired query parameters. This minimizes manual updates across components and helps maintain robust tracking without introducing errors.
