Developing Vue Apps with the Quasar Library — Chips and Progress Spinners

Spread the love

Quasar is a popular Vue UI library for developing good looking Vue apps.

In this article, we’ll take a look at how to create Vue apps with the Quasar UI library.

Truncating Text in Chips

We can truncate the text in chips by writing:

<!DOCTYPE html>
<html>
  <head>
    <link
      href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
      rel="stylesheet"
      type="text/css"
    />
    <link
      href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
      rel="stylesheet"
      type="text/css"
    />
  </head>
  <body class="body--dark">
    <script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
    <div id="q-app">
      <q-layout
        view="lHh Lpr lFf"
        container
        style="height: 100vh;"
        class="shadow-2 rounded-borders"
      >
        <q-chip
          removable
          color="primary"
          text-color="white"
          icon="cake"
          :label="label"
          :title="label"
          style="max-width: 150px;"
        >
        </q-chip>
      </q-layout>
    </div>
    <script>
      new Vue({
        el: "#q-app",
        data: {
          label: "Lorem ipsum dolor sit amet, consectetur adipiscing elit."
        }
      });
    </script>
  </body>
</html>

Circular Progress

We can add a progress spinner with Quasar.

To do this, we use the q-circular-progress component:

<!DOCTYPE html>
<html>
  <head>
    <link
      href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
      rel="stylesheet"
      type="text/css"
    />
    <link
      href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
      rel="stylesheet"
      type="text/css"
    />
  </head>
  <body class="body--dark">
    <script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
    <div id="q-app">
      <q-layout
        view="lHh Lpr lFf"
        container
        style="height: 100vh;"
        class="shadow-2 rounded-borders"
      >
        <q-circular-progress
          :value="70"
          size="50px"
          color="orange"
          class="q-ma-md"
        >
        </q-circular-progress>
      </q-layout>
    </div>
    <script>
      new Vue({
        el: "#q-app",
        data: {}
      });
    </script>
  </body>
</html>

The value sets the progress value. It can be between 0 and 100.

size sets the size.

color sets the ring color.

Also, we can set the color of the center with the center-color prop:

<!DOCTYPE html>
<html>
  <head>
    <link
      href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
      rel="stylesheet"
      type="text/css"
    />
    <link
      href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
      rel="stylesheet"
      type="text/css"
    />
  </head>
  <body class="body--dark">
    <script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
    <div id="q-app">
      <q-layout
        view="lHh Lpr lFf"
        container
        style="height: 100vh;"
        class="shadow-2 rounded-borders"
      >
        <q-circular-progress
          :value="70"
          size="50px"
          color="orange"
          center-color="grey-8"
          class="q-ma-md"
        >
        </q-circular-progress>
      </q-layout>
    </div>
    <script>
      new Vue({
        el: "#q-app",
        data: {}
      });
    </script>
  </body>
</html>

We can reverse the direction of the spinner with the reverse prop:

<!DOCTYPE html>
<html>
  <head>
    <link
      href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
      rel="stylesheet"
      type="text/css"
    />
    <link
      href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
      rel="stylesheet"
      type="text/css"
    />
  </head>
  <body class="body--dark">
    <script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
    <div id="q-app">
      <q-layout
        view="lHh Lpr lFf"
        container
        style="height: 100vh;"
        class="shadow-2 rounded-borders"
      >
        <q-circular-progress
          :value="70"
          size="50px"
          color="orange"
          center-color="grey-8"
          reverse
          class="q-ma-md"
        >
        </q-circular-progress>
      </q-layout>
    </div>
    <script>
      new Vue({
        el: "#q-app",
        data: {}
      });
    </script>
  </body>
</html>

We can add content inside the spinner by population the default slot:

<!DOCTYPE html>
<html>
  <head>
    <link
      href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
      rel="stylesheet"
      type="text/css"
    />
    <link
      href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
      rel="stylesheet"
      type="text/css"
    />
  </head>
  <body class="body--dark">
    <script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
    <div id="q-app">
      <q-layout
        view="lHh Lpr lFf"
        container
        style="height: 100vh;"
        class="shadow-2 rounded-borders"
      >
        <q-circular-progress
          show-value
          class="text-white q-ma-md"
          :value="75"
          size="90px"
          :thickness="0.2"
          color="orange"
          center-color="grey-8"
          track-color="transparent"
        >
          <q-icon name="volume_up"></q-icon>
        </q-circular-progress>
      </q-layout>
    </div>
    <script>
      new Vue({
        el: "#q-app",
        data: {}
      });
    </script>
  </body>
</html>

We can make the spinner spin forever with the indeterminate prop:

<!DOCTYPE html>
<html>
  <head>
    <link
      href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
      rel="stylesheet"
      type="text/css"
    />
    <link
      href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
      rel="stylesheet"
      type="text/css"
    />
  </head>
  <body class="body--dark">
    <script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
    <div id="q-app">
      <q-layout
        view="lHh Lpr lFf"
        container
        style="height: 100vh;"
        class="shadow-2 rounded-borders"
      >
        <q-circular-progress
          indeterminate
          size="50px"
          color="lime"
          class="q-ma-md"
        >
        </q-circular-progress>
      </q-layout>
    </div>
    <script>
      new Vue({
        el: "#q-app",
        data: {}
      });
    </script>
  </body>
</html>
