Vue.js is an easy to use web app framework that we can use to develop interactive front end apps.

In this article, we’ll look at the best packages for checking network status, particle background, checkboxes and radio buttons, and infinite scrolling.

Vue Offline

Vue Offline is a good plugin for detecting whether a Vue app is online for offline.

To use it, we run:

npm i vue-offline

Then we can use it by writing:

main.js

import Vue from "vue";
import App from "./App.vue";
import VueOffline from "vue-offline";

Vue.use(VueOffline);
Vue.config.productionTip = false;
new Vue({
  render: h => h(App)
}).$mount("#app");

App.vue

<template>
  <div>
    <p v-if="isOnline">online</p>
    <p v-if="isOffline">Toffline</p>
  </div>
</template>

<script>
export default {
  mounted() {
    this.$on("offline", () => {
      console.log('offline')
    });
  }
};
</script>

We register the plugin., Then we can use the isOnline and isOffline properties to check whether the app is online or offline.

Also, we can use the $on method to listen to network status changes.

We can also save data to local storage to make the data available offline.

To save the data, we can write:

<template>
  <div>
    <p v-if="isOnline">online</p>
    <p v-if="isOffline">Toffline</p>
  </div>
</template>

<script>
export default {
  mounted() {
    this.$offlineStorage.set("user", { foo: "bar" });
  }
};
</script>

We use the this.$offlineStorage.set method to save the data.

The first argument is the key and the 2nd is the value.

We can use this.$offlineStorage.get to get the value by the key.
