It supports Vue 3 with PrimeVue 3 and Vue 2 with PrimeVue 2.

Mitt EventBus

Toast requires Mitt, a tiny 200b EventBus implementation.

Toast messages are dynamically created using a ToastService that needs to be installed globally before the application instance is created.

import {createApp} from 'vue';
import ToastService from 'primevue/toastservice';

const app = createApp(App);
Enter fullscreen mode Exit fullscreen mode


import Toast from 'primevue/toast';
Enter fullscreen mode Exit fullscreen mode

Getting Started

Ideal location of a Toast is the main application template so that it can be used by any component within the application. A single message is represented by the Message interface in PrimeVue that defines various properties such as severity, summary and detail.

Options API

$toast is available as a property in the application instance.

export default {
    mounted() {
        this.$toast.add({severity:'success', summary: 'Success Message', detail:'Order submitted', life: 3000});
Enter fullscreen mode Exit fullscreen mode

Composition API

The toast instance can be injected with the useToast function.

import { defineComponent } from "vue";
import { useToast } from "primevue/usetoast";

export default defineComponent({
    setup() {
        const toast = useToast();
        toast.add({severity:'info', summary: 'Info Message', detail:'Message Content', life: 3000});
Enter fullscreen mode Exit fullscreen mode


There are four possible values for the severity of a message. Info is the default.

  • success
  • info
  • warn
  • error


There are four positions available for the toast container defined by the position property that defaults to "top-right". Other valid values are "top-left", "top-center", "bottom-left", "botton-center", "bottom-right" and "center".

<Toast />
<Toast position="top-left" />
<Toast position="top-center" />
<Toast position="top-right" />
<Toast position="center" />
<Toast position="bottom-left" />
<Toast position="bottom-center" />
<Toast position="bottom-right" />
Enter fullscreen mode Exit fullscreen mode


A message can be targeted to a specific Toast component if their group properties match. Messages without a group are forwarded to the default Toast component that does not have a group defined.

<Toast />
<Toast position="mykey" />
Enter fullscreen mode Exit fullscreen mode
this.$toast.add({severity:'success', summary: 'Default Message'});
this.$toast.add({severity:'success', summary: 'Specific Message', group: 'mykey'});
Enter fullscreen mode Exit fullscreen mode

Clearing Messages

removeGroup(group) clears the messages for a specific Toast whereas removeAllGroups() method clears all messages.


Toast supports various themes featuring Material, Bootstrap, Fluent as well as your own custom themes via the Designer tool.
