Vue Page Title

Install

yarn add vue-page-title # npm i vue-page-title
Copy

Setup

import { createApp } from 'vue';
import { pageTitle } from 'vue-page-title';

const app = createApp(Root);

app.use(
  pageTitle({
    suffix: '- Vue Page Title',
    mixin: true,
  }),
);
Copy

Examples

• mixin 01
• mixin 02
• composition

Compatibility

Vue	Version
v2	v1.*
v3	v3.*

Migration from v2

Version 3 ships as an ES module only. Update your imports if you relied on legacy bundle fields:

import { pageTitle } from 'vue-page-title';
Copy

Breaking changes in v3:

• Removed UMD, CJS, and IIFE builds (main, unpkg, and jsdelivr fields)
• Package entry is now exports.import pointing to dist/index.js
• Node.js 20.19+ is required for development and CI

Migration from v1

All resources from v1 works on v2.

Now mixin is optional and must be defined as true to be automatically registered in the app.

Options

Name	Type	Description
suffix	String	suffix for the value of the page title tag
prefix	String	prefix for the value of the page title tag
separator	String	a string that comes between the prefix and the title / the title and the suffix, defaults to a space
mixin	Boolean	if true, enable plugin mixin in the components
router	VueRouter instance	if present, allows you to set the title via the route.
setTitleMethod	Function	custom method of setting title

Usage

Composition API

Copy

const { title } = useTitle('initial title`)
Copy

React from ref state

const name = ref('initial name');
const { title } = useTitle(name);
Copy

Use like a watch source argument

const product = ref({ name: 'One Piece 1017' });
const { title } = useTitle(() => product.name);
Copy

Pass a computed as argument

const product = ref({ name: 'One Piece 1017' });
const name = computed(() => product.name);
const { title } = useTitle(name);
Copy

Use setTitle to dynamically change the title

const product = ref({ name: 'One Piece 1017' });
const { setTitle } = useTitle();

watchEffect(() => {
  setTitle(product.name);
});
Copy

Mixin

With the mixin option enabled, just set the title option inside the component.
Within the component it is still possible to update the $title state using $setPageTitle function, it is also available to be used within the component template.

The option mixin must be true.

Copy

Function title

You are able to turn the title changes acative, like a computed.

Copy

This is particularly useful for internationalization.
This is an example using vue-i18n@9.

export default {
  title: ({ $t }) => $t('pages.clients.title'),
};
Copy

Vue Router integration

Setup

import { createApp } from 'vue';
import { pageTitle } from 'vue-page-title';
import router from 'path/to/application/router';

const app = createApp(Root);

app.use(pageTitle({ router }));
Copy

path/to/application/router

import { createRouter, createWebHashHistory } from 'vue-router';
import FooComponent from 'path/to/foo-component';
import HomeComponent from 'path/to/home-component';

const routes = [
  {
    path: '/',
    component: HomeComponent,
    meta: {
      title: 'Home Page', // Title must be a string.
    },
  },
  {
    path: '/foo',
    component: FooComponent,
    meta: {
      title: 'Foo Page',
    },
  },
];

export default createRouter({
  history: createWebHashHistory(),
  routes,
});
Copy

Watching routes

export default {
  title() {
    return `My title is: ${this.$route.query.foo}`;
  },
};
