What is the most effective method for defining 2 routes that point to the same component?

Although it may seem straightforward, I'm struggling to find the most efficient method for this particular scenario in Vue.js.

I am using Vue Cli 3 and I need to have multiple routes leading to the same Home page within the application.

The idea is to have an affiliate number as a parameter - or no affiliate at all.

What I've tried so far is defining two different paths pointing to the same home component in router.js:

    {
      path: '/',
      name: 'home',
      component: Home
    },
    {
      path: '/affId=:affiliateNumber?',
      name: 'home',
      component: Home
    },

This code technically works, but it's not an ideal solution as it triggers a warning stating '[vue-router] Duplicate named routes definition'.

Could someone offer advice on the best approach to tackle this issue? Any help would be greatly appreciated.

Answer №1

The reason you are encountering the error is because you have assigned the same name (home) to both routes. To resolve this, consider renaming them to something like home and home-2, or any other distinct names. It is generally recommended to stick to using a single route and adjusting the parameters and queries accordingly.

In the scenario you provided, there seems to be a misunderstanding in route mapping. A query parameter should not directly follow a slash; instead, it should always be linked to the current route using a ?.

Depending on your specific requirements, you could simplify your routes. For instance, if you need to access a URL parameter, you can define a route as follows:

{
  path: '/:affiliateNumber',
  name: 'home',
  component: Home
},

This allows you to retrieve the value of 

:affiliateNumber</code whenever necessary in your code. Additionally, this route could function as a child route under a parent with <code>path: '/'
.

However, in your case, simply using a query parameter might suffice. By doing so, you can avoid dealing with child routes or other complexities since query parameters are always optional. Therefore, you could keep your route definition simple like this:

{
  path: '/',
  name: 'home',
  component: Home
},

...and append any desired query parameters by using /home?affId=123.
