How to make router parameter optional in Vue.js

in Code Write a comment

In this tutorial, you’ll learn how to make component query parameters optional in Vue.js.

Suppose you have a Users component with the following route /users. It renders a list of all users.

{
  path: '/users/',
  components: Users,
  ...
}

Now you also would like to render individual users by passing user ID as a router parameter. You can do that by adding a parameter and making it optional.

{
  path: '/users/:id?', // id is optional
  components: Users,
  ...
}

To make a query parameter optional – you need to add a question mark "?" after the parameter name.
