Sometimes, we want to fix pushing to Vuex store array not working in Vue.js.

In this article, we’ll look at how to fix pushing to Vuex store array not working in Vue.js.

How to fix pushing to Vuex store array not working in Vue.js?

To fix pushing to Vuex store array not working in Vue.js, we should commit the mutation to change the array state.

For instance, we write

const store = new Vuex.Store({
  state: {
    customers: [{ id: 1, name: "user 1" }],
  },
  mutations: {
    addCustomer(state, customer) {
      state.customers.push(customer);
    },
  },
});

to add the addCustomer mutation that calls state.customers.push to add an entry to the customers state.

And then in our component, we write

<script>
//...
export default {
  //...
  methods: {
    addCustomer() {
      store.commit("addCustomer", { id: 2, name: "User 2" });
    },
  },
  //...
};
</script>

to call store.commit with 'addCustomer' and the item to add to commit the addCustomer mutation.

Sometimes, we want to fix $route is not defined with Vue.js.

In this article, we’ll look at how to fix $route is not defined with Vue.js.

How to fix $route is not defined with Vue.js?

To fix $route is not defined with Vue.js, we should make sure have Vue Router in our Vue project and we use regular functions and this.$route in our methods and hooks.

For instance, we write

import Vue from "vue";
import Router from "vue-router";
//...
Vue.use(Router);

const router = new VueRouter({
  routes: [
    { path: "/videos", name: "allVideos", component: Videos },
    { path: "/videos/:id/edit", name: "editVideo", component: VideoEdit },
  ],
});

new Vue({
  el: "#app",
  router,
  //...
});

to add the Router plugin with Vue.use and add router into our Vue instance.

And then in our component methods, we write something like

<script>
//...
export default {
  //...
  data() {
    return {
      id: this.$route.params.id,
    };
  },
  //...
};
</script>

where data is a regular function instead of an arrow function.

Conclusion
