Navigating between different pages and resources is a cornerstone of web applications. When building Single Page Applications (SPAs) with Vue.js, Vue Router plays a pivotal role in managing these transitions. A common question that arises is: Can Vue Router open a link in a new tab? The short answer is yes, but it requires a slightly different approach than traditional HTML links. While Vue Router is designed to handle navigation within the application without full page reloads, sometimes you need a link to open in a separate tab or window. This might be to link to an external website, or to preserve the current state of the application while allowing the user to explore another resource. Understanding how to achieve this is crucial for providing a seamless and intuitive user experience. We’ll explore the different methods and best practices for opening links in new tabs when using Vue Router, ensuring your users can navigate your application and external resources with ease.

Understanding Vue Router and its Navigation Model

Vue Router is the official router for Vue.js, providing a declarative way to manage application routes. It allows you to map different URLs to specific components, creating a smooth and responsive user experience. Unlike traditional multi-page applications, Vue Router intercepts navigation events and updates the view without requiring a full page reload. This approach significantly improves performance and responsiveness. However, this also means that standard HTML link behavior needs to be adapted when you want to open a link in a new tab.

The core principle of Vue Router is to handle navigation internally. When a user clicks a <router-link>, Vue Router intercepts the click event and updates the URL and the displayed component accordingly. This happens client-side, providing a fast and seamless transition. Vue Router leverages the browser’s history API to maintain a navigation stack, allowing users to use the back and forward buttons. This behavior is ideal for internal navigation within your SPA, but it doesn’t directly support opening links in new tabs without additional configuration.

To effectively use Vue Router for external links or to open links in new tabs, developers need to bypass the default internal navigation behavior. This can be achieved using standard HTML <a> tags or by customizing the <router-link> component. Understanding these options is key to providing a flexible and user-friendly navigation experience. Knowing when to use Vue Router’s built-in navigation versus native HTML links is crucial for optimal performance and usability.

Using HTML <a> Tags for New Tabs

The simplest way to open a link in a new tab with Vue is to use a standard HTML <a> tag with the target="_blank" attribute. This attribute tells the browser to open the linked resource in a new tab or window. This method bypasses Vue Router’s internal navigation entirely, making it suitable for external links or when you specifically want a new tab to open. Be sure to include rel=“noopener noreferrer” for security best practices.

Here’s an example of how to use the <a> tag in a Vue template:

html Open Example.com in a new tabThe rel="noopener noreferrer" attribute is crucial for security. When you open a link in a new tab using target="_blank", the new tab has access to the window.opener property, which provides access to the original page. This can be a security risk, as the new tab could potentially redirect the original page to a malicious website. The rel="noopener" attribute prevents this by breaking the link between the two tabs. The noreferrer attribute further enhances privacy by preventing the new tab from knowing which page referred it.

Using <a> tags offers a straightforward solution for opening links in new tabs, ensuring compatibility across browsers and avoiding conflicts with Vue Router’s internal navigation. This approach is particularly useful for linking to external websites or documents, providing a seamless transition for users while maintaining the integrity of your Vue application. According to a study by Mozilla, using rel=“noopener” significantly reduces the risk of tabnabbing attacks [1].

Customizing <router-link> for New Tabs

While using <a> tags is a direct approach, you might prefer to customize the <router-link> component to handle new tab behavior. This allows you to maintain a consistent look and feel within your Vue application and leverage Vue Router’s features, such as dynamic route matching and named routes. One method is to use the tag prop to render the as an tag, then include the target and rel attributes.

Here’s an example of how to customize <router-link>:

vue Open Example.com in a new tab In this example, the tag="a" prop tells Vue Router to render the component as an <a> tag instead of its default internal component. The target="_blank" and rel="noopener noreferrer" attributes function as they would in a standard <a> tag. The href attribute is essential; Vue Router won’t automatically set the href attribute when using tag=“a”, so you must provide it manually. This approach allows you to use Vue Router’s routing capabilities while still achieving the desired new tab behavior. It’s crucial to ensure that the to prop and the href attribute point to the correct URL.

Another approach involves using a custom component or directive to handle the new tab functionality. This allows for more complex logic and better reusability. For example, you could create a custom component that wraps the <router-link> and automatically adds the target="_blank" and rel="noopener noreferrer" attributes when a specific prop is set. This approach provides a cleaner and more maintainable solution, especially when dealing with multiple links that need to open in new tabs. According to the Vue.js documentation, custom components can significantly enhance code reusability and maintainability [2].

Best Practices and Considerations

When implementing new tab functionality with Vue Router, it’s essential to consider user experience and security. Ensure that users are aware when a link will open in a new tab, especially if it leads to an external website. Consider adding a visual cue, such as an icon, to indicate that the link will open in a new tab. This helps users understand the expected behavior and avoid confusion.

Here are some best practices to follow:

• Always use rel="noopener noreferrer" when opening links in new tabs. This protects your users from potential security vulnerabilities.
• Provide clear visual cues to indicate when a link will open in a new tab.
• Consider using a custom component or directive for consistent new tab behavior throughout your application.

Proper error handling and accessibility are also important considerations. Ensure that your links are accessible to users with disabilities. Use appropriate ARIA attributes to provide additional information about the link’s behavior. For example, you can use the aria-label attribute to describe the link’s purpose and indicate that it will open in a new tab. Additionally, test your links thoroughly to ensure they function correctly across different browsers and devices. A study by the W3C highlights the importance of accessible web content [3].

In summary, handling links that open in new tabs with Vue Router requires a thoughtful approach. By using standard HTML <a> tags or customizing the <router-link> component, you can provide a seamless and secure user experience. Remember to prioritize security by using rel="noopener noreferrer" and provide clear visual cues to indicate new tab behavior. This ensures that your users can navigate your application and external resources with ease and confidence.

FAQ: Opening Links in New Tabs with Vue Router

**Q: Why use `rel="noopener noreferrer"` when opening links in a new tab?**

A: The `rel="noopener noreferrer"` attribute is crucial for security. When you use `target="_blank"` without it, the new tab has access to the original page via `window.opener`, which can be exploited for malicious purposes. `noopener` breaks this link, and `noreferrer` prevents the new tab from knowing which page referred it.

**Q: Can I use Vue Router's `` to open external links in a new tab?**

A: Yes, you can customize the `` component using the `tag="a"` prop and adding the `target="_blank"` and `rel="noopener noreferrer"` attributes. Remember to also include the `href` attribute with the external URL.

**Q: What's the best approach for handling multiple links that need to open in new tabs?**

A: Consider creating a custom component or directive to handle the new tab functionality. This allows for more complex logic, better reusability, and a cleaner codebase.

Now that you’re equipped with the knowledge to effectively manage links in your Vue applications, consider exploring other aspects of Vue Router, such as dynamic route matching or advanced navigation guards.

Question & Answer :
I have a summary page and a detail subpage. All of the routes are implemented with vue-router (v 0.7.x) using programmatic navigation like this:

this.$router.go({ path: "/link/to/page" }) 

However, when I route from the summary page to the subpage, I need to open the subpage in a new tab just as one would by adding _target="blank" to an <a> tag.

Is there a way to do this?

I think that you can do something like this:

const routeData = this.$router.resolve({name: 'routeName', query: {data: "someData"}}); window.open(routeData.href, '_blank'); 

It worked for me.

Update

For composition Api:

import { useRouter } from 'vue-router' const router = useRouter(); const routeData = router.resolve({name: 'routeName', query: {data: "someData"}}); window.open(routeData.href, '_blank');
