Watch route changes in Vue.js with Typescript : <p>I'd like to detect changes in my URL in a Vue.js application using TypeScript. In JavaScript this can be done as follows:</p>

<pre><code>watch: {
  '$route': {
     handler: 'onUrlChange',
     immediate: true,
     deep: true
   }
},

onUrlChange(newUrl){
   // Some action
}
</code></pre>

<p>How could I do the same in TypeScript?</p>
