How to change page titles when using vue-router?
I would like to specify my titles within the route definition if possible. What is normally specified in <head><title> and appears in the browser title bar.
I have my project set up as follows:
main.js
import Vue from 'vue'
import App from './App.vue'
import VeeValidate from 'vee-validate';
import router from './router'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(VeeValidate);
Vue.use(ElementUI);
Vue.config.productionTip = false
new Vue({
router,
render: h => h(App)
}).$mount('#app')
router.js
import Vue from 'vue'
import Router from 'vue-router'
import Skills from './components/Skills.vue'
import About from './components/About.vue'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'skills',
component: Skills,
meta: { title: 'Skills - MyApp' } // <- I would to use this one
},
{
path: '/about/:name', // Add /:name here
name: 'about',
component: About,
meta: { title: 'About - MyApp' }
}
]
})
Preferably, I would want an automatic system instead of changing page title on the created function of every component. Thanks.

You can use a navigation guard with the router definition:
import Vue from 'vue';
const DEFAULT_TITLE = 'Some Default Title';
router.afterEach((to, from) => {
// Use next tick to handle router history correctly
// see: https://github.com/vuejs/vue-router/issues/914#issuecomment-384477609
Vue.nextTick(() => {
document.title = to.meta.title || DEFAULT_TITLE;
});
});
You'll need to change your export to:
const router = new Router({ ... });
...
export default router;
Or you can use an immediate watcher on your root component:
export default {
name: 'App',
watch: {
$route: {
immediate: true,
handler(to, from) {
document.title = to.meta.title || 'Some Default Title';
}
},
}
};
