We're Having Toast: Toast Notifications in PrimeVue

Toast notifications are an essential component of modern web applications, providing users with timely feedback and alerts. In Vue.js applications, PrimeVue offers a convenient and customizable way to implement toast notifications through its Toast component. In this article, we'll explore how to use PrimeVue's toast notifications in Vue.js applications and examine a sample code snippet that demonstrates their usage.

import { defineStore } from "pinia";
import type { ToastMessageOptions } from "primevue/toast";
import { useToast } from "primevue/usetoast";

export const toastStore = defineStore("toastStore", () => {
  const toast = useToast();
  function addToast(
    severity: ToastMessageOptions["severity"] = "info",
    summary: ToastMessageOptions["summary"] = "",
    detail: ToastMessageOptions["detail"] = "",
    life: ToastMessageOptions["life"] = 0
  ) {
    toast.add({
      severity,
      summary: summary.toUpperCase(),
      detail: `${detail} ${life}ms!`,
      life,
    });
    if (life > 0) {
      setTimeout(() => {
        removeToast(life);
      }, life);
    }
  }
  function removeToast(life: ToastMessageOptions["life"]) {
    toast.add({
      severity: "success",
      summary: "Done!".toUpperCase(),
      detail: `Toast cooked in ${life}ms!`,
    });
  }
  return { addToast, removeToast };
});

Imports:

The code imports necessary functions and types from pinia and primevue libraries.

Store Definition:

toastStore is defined using defineStore from Pinia. This store will manage toast notifications in the application.

Toast Initialization:

useToast hook from PrimeVue is used to initialize the toast instance, which will be used to add and remove toast notifications.

Add Toast Function:

The addToast function creates a new toast with severity, summary, detail, and life duration, adding it with toast.add. For life > 0, a timeout auto-removes it.

Remove Toast Function:

The removeToast function is responsible for removing the toast notification. It adds a success toast indicating that the original toast has been successfully removed.

Return Object:

The store returns an object containing the addToast and removeToast functions, which can be accessed and used in Vue components.
