How can I get query parameters from a URL in Vue.js?

How can I fetch query parameters in Vue.js?

E.g. http://somesite.com?test=yay.

Can’t find a way to fetch or do I need to use pure JS or some library for this?

According to the docs of route object, you have access to a $route object from your components, which exposes what you need. In this case

//from your component
console.log(this.$route.query.test) // outputs 'yay'

Without vue-route, split the URL

var vm = new Vue({
  ....
  created() {
    let uri = window.location.href.split('?');
    if(uri.length == 2) {
      let vars = uri[1].split('&');
      let getVars = {};
      let tmp = '';
      vars.forEach(function(v) {
        tmp = v.split('=');
        if(tmp.length == 2)
          getVars[tmp[0]] = tmp[1];
      });
      console.log(getVars);
      // do 
    }
  },
  updated() {
  },
....

Another solution https://developer.mozilla.org/en-US/docs/Web/API/HTMLHyperlinkElementUtils/search:

var vm = new Vue({
  ....
  created() {
    let uri = window.location.search.substring(1); 
    let params = new URLSearchParams(uri);
    console.log(params.get("var_name"));
  },
  updated() {
  },
....

More detailed answer to help the newbies of VueJS:

• First define your router object, select the mode you seem fit. You can declare your routes inside the routes list.
• Next you would want your main app to know router exists, so declare it inside the main app declaration .
• Lastly they $route instance holds all the information about the current route. The code will console log just the parameter passed in the url. (*Mounted is similar to document.ready , .ie its called as soon as the app is ready)

And the code itself:

<script src="https://unpkg.com/vue-router"></script>
var router = new VueRouter({
    mode: 'history',
    routes: []
});
var vm =  new Vue({
    router,
    el: '#app',
    mounted: function() {
        q = this.$route.query.q
        console.log(q)
    },
});
