How to Dynamically Update Page Titles in VueJS with Vue Router

When building a web application, it’s essential to ensure that the user experience is smooth and personalized. One often-overlooked aspect of this is managing the page title effectively, particularly when navigating between different components. If you're working with VueJS and Vue Router, you might find yourself needing to update the page title based on the user's information—like displaying the username in the title when viewing a specific user's profile.

In this guide, we’ll explore how to dynamically set the page title in your VueJS application based on data retrieved from the Vuex store. This approach not only enhances SEO but also improves user navigation by providing informative context for each page.

The Problem: Updating the Page Title

Let's set the scene with a common scenario. Imagine you're developing an application with multiple routes, each route representing different components or views. You want the title of the page to reflect the specific content being viewed. For instance, if a user navigates to their profile page, you might want the title to read "Cool Page - [USER_NAME]" instead of a generic title.

However, this title update can be challenging when you rely on data fetched from a Vuex store based on route parameters. Here's a simplified version of how your routes might currently look:

The challenge arises when trying to update the title dynamically based on the fetched data from Vuex.

The Solution: Dynamically Updating the Page Title

To achieve this dynamic title updating, you will import your Vuex store to access the user data needed for the title. Here’s a step-by-step guide to implement this:

Step 1: Import Your Vuex Store

At the top of your router configuration file, import your store to gain access to the Vuex getters:

Step 2: Update the Router After Each Navigation

You can utilize the afterEach hook in your Vue Router setup to change the document title whenever a route is navigated. Update your afterEach function like so:

Key Points:

Document Title: The document title is updated every time a route change occurs.

Conditional Title Setting: If the route corresponds to a user's page, the title will display the username based on the data fetched from the Vuex store. For all other routes, it will return the title defined in the route’s meta data or fall back to a default title.

User Data Verification: Always ensure user info is present to avoid errors.

By using the above methodology, you can effectively manage the page titles, which enhances the user experience and keeps your application SEO-friendly.

Conclusion

By implementing dynamic page titles in your VueJS application, you not only improve usability but also provide more informative content to users and search engines alike. This approach can easily be adjusted to fit the specific needs of your application and enhances the overall navigation and structure of your site.

Take the time to consider how you present your application's titles, and implement these changes to create a more engaging and worthwhile user experience. Happy coding!
