Duplicate Meta Tags In Head When Using Vike-react-query With HTML Streaming

by ADMIN 76 views

Introduction

When using Vike-React-Query with HTML Streaming, setting page-specific meta tags such as title, description, and keywords can be a crucial aspect of search engine optimization (SEO). However, when using the <Head> component to set these meta tags, a peculiar issue arises. In this article, we will delve into the problem of duplicate meta tags being generated when using Vike-React-Query with HTML Streaming.

Description

The issue at hand is that when using the <Head> component to set meta tags, they are being duplicated on the page. This is evident when testing the page with Google's Rich Results Test, where the meta tags are visible, but duplicated. The problem is not just a matter of aesthetics; it can also have a significant impact on SEO, as Google may ignore meta tags if they are duplicated, which is not a valid HTML structure.

Investigation

To investigate this issue, we need to understand how Vike-React-Query with HTML Streaming works. The <Head> component is used to set meta tags, and it is integrated with Vike-React-Query. However, when testing the page with Google's Rich Results Test, we see that the meta tags are duplicated. This suggests that there is an issue with how the meta tags are being generated or rendered.

Code Example

The code example provided in the Vike-React-Query documentation is as follows:

config({
  title,
  Head: (
    <>
      <meta name="description" content={description} />
      <meta name="keywords" content={keywords} />
    </>
  ),
});

This code sets the meta tags using the <Head> component. However, when testing the page with Google's Rich Results Test, we see that the meta tags are duplicated.

Reproduction Example

To reproduce this issue, we can use the code example provided in the Vike-Streaming-Meta-Demo repository. However, deploying this code on Vercel can be challenging, as it requires modifying the build and output settings.

Environment

The environment used to reproduce this issue is as follows:

  • Vike: 0.4.224
  • Vike-React: 0.5.13
  • Vike-React-Query: 0.1.3
  • Node.js version: v20.12.2

Conclusion

In conclusion, the issue of duplicate meta tags being generated when using Vike-React-Query with HTML Streaming is a complex problem that requires further investigation. The code example provided in the Vike-React-Query documentation is not sufficient to resolve this issue, and deploying the code on Vercel can be challenging. To resolve this issue, we need to understand how Vike-React-Query with HTML Streaming works and how the meta tags are being generated or rendered.

Possible Solutions

One possible solution to this issue is to modify the code to prevent the duplication of meta tags. This can be achieved by using a unique identifier for each meta tag or by using a different approach to set the meta tags.

Another possible solution is to modify the Vike-React-Query documentation to provide a more detailed example of how to set meta tags using the <Head> component.

Future Work

In the future, we can investigate further into the issue of duplicate meta tags being generated when using Vike-React-Query with HTML Streaming. We can also explore other possible solutions to this issue, such as modifying the Vike-React-Query code or using a different approach to set the meta tags.
