Vue 3 — Slot Shorthands

Vue 3 — Slot Shorthands

Various shorthands for using slots.If we have one slot, then we don’t need the template element. We can put the v-slot directive right on the opening component tag.

Shorthand Syntax for Default Slots

If we have one slot, then we don’t need the template element.

We can put the v-slot directive right on the opening component tag.

For instance, we can write:

<!DOCTYPE html>
<html lang="en">
  <head>
    <title>App</title>
    <script src="https://unpkg.com/[email protected]"></script>
  </head>
  <body>
    <div id="app">
      <items v-slot="slotProps">
        <b>{{ slotProps.item.name }}</b>
      </items>
    </div>
    <script>
      const app = Vue.createApp({});
      app.component("items", {
        template: `
          <ul>
            <li v-for="( item, index ) in items">
              <slot v-bind:item="item"></slot>
            </li>
          </ul>
        `,
        data() {
          return {
            items: [{ name: "apple" }, { name: "orange" }, { name: "grape" }]
          };
        }
      });
      app.mount("#app");
    </script>
  </body>
</html>

We have the v-slot directive on the component tag, which is only allowed when we have one slot in our component.
