Allow Original Styleheet To Remain In Head
Introduction
When working with web applications, it's not uncommon to encounter issues with stylesheets and their interaction with other libraries or frameworks. In this article, we'll explore a specific problem related to the Anchor Polyfill and its compatibility with Turbo, a popular JavaScript library for building fast and efficient web applications.
The Problem
The Anchor Polyfill is a useful tool for adding support for the <link rel="stylesheet" href="..."> element, which is not natively supported in all browsers. However, when used in conjunction with Turbo, issues can arise. Turbo tracks the contents of the <head> element and adds or removes elements as needed, which can break the polyfill.
To better understand the issue, let's take a look at a minimal reproduction of the problem, courtesy of the author of the Anchor Polyfill: https://github.com/robbevp/anchor-polyfull-turbo.
The Solution
One potential solution to this problem is to not remove the original <link> element once it has been polyfilled. As long as the original element remains above the inline styles in the <head>, the polyfilled styles should be used instead. This approach would eliminate the need for the data-turbo-track attribute and allow both the original and polyfilled styles to coexist in the <head>.
However, this solution raises another question: how would we track changes to the assets and determine when a full page reload is necessary? While this may seem like a complex problem, it's likely solvable with a bit of creativity and experimentation.
Alternatives Considered
In the reproduction provided, the author explored using data-turbo-track="dynamic" and re-applying the polyfill after every navigation. While this approach comes closest to solving the problem, it does involve a significant amount of redundant work. To mitigate this issue, the author suggests limiting the polyfill to only those styles that use the Anchor Polyfill, and placing them in their own stylesheet.
Benefits of the Proposed Solution
By allowing the original stylesheet to remain in the <head>, we can avoid the need for redundant work and simplify the polyfill's functionality. This approach also provides a more elegant solution to the problem, as it eliminates the need for the data-turbo-track attribute and allows both the original and polyfilled styles to coexist in harmony.
Implementation Details
To implement this solution, we would need to modify the Anchor Polyfill to leave the original <link> element in the <head> and only add the polyfilled styles as needed. We would also need to develop a mechanism for tracking changes to the assets and determining when a full page reload is necessary.
While this may require some additional development effort, the benefits of this approach make it well worth the investment. By allowing the original stylesheet to remain in the <head>, we can create a more efficient and effective polyfill that works seamlessly with Turbo.
Conclusion
In conclusion, the proposed solution to the problem of the Anchor Polyfill and Turbo is a simple yet effective one. By allowing original stylesheet to remain in the <head>, we can avoid redundant work and simplify the polyfill's functionality. This approach also provides a more elegant solution to the problem, as it eliminates the need for the data-turbo-track attribute and allows both the original and polyfilled styles to coexist in harmony.

Future Development
As the Anchor Polyfill and Turbo continue to evolve, it's likely that this issue will be addressed in future updates. However, by implementing the proposed solution, we can ensure that our applications continue to work seamlessly with both libraries.
Recommendations
Based on our analysis, we recommend the following:
- Modify the Anchor Polyfill to leave the original
<link>element in the<head>and only add the polyfilled styles as needed. - Develop a mechanism for tracking changes to the assets and determining when a full page reload is necessary.
- Consider limiting the polyfill to only those styles that use the Anchor Polyfill, and placing them in their own stylesheet.
Introduction
In our previous article, we explored the issue of the Anchor Polyfill and its compatibility with Turbo. We proposed a solution that involves allowing the original stylesheet to remain in the <head> and only adding the polyfilled styles as needed. In this article, we'll answer some frequently asked questions about this solution and provide additional insights into its implementation.
Q: Why is the original stylesheet being removed in the first place?
A: The original stylesheet is being removed because Turbo tracks the contents of the <head> element and adds or removes elements as needed. When the polyfill is applied, it replaces the original stylesheet with its own polyfilled version. However, this can cause issues with the Turbo library, which relies on the original stylesheet being present in the <head>.
Q: How does the proposed solution address the issue of the original stylesheet being removed?
A: The proposed solution involves modifying the Anchor Polyfill to leave the original stylesheet in the <head> and only adding the polyfilled styles as needed. This approach ensures that the original stylesheet remains present in the <head> and is not removed by Turbo.
Q: What are the benefits of allowing the original stylesheet to remain in the <head>?
A: Allowing the original stylesheet to remain in the <head> provides several benefits, including:
- Simplifying the polyfill's functionality
- Eliminating the need for redundant work
- Providing a more elegant solution to the problem
- Ensuring that the original stylesheet remains present in the
<head>
Q: How does the proposed solution impact the performance of the application?
A: The proposed solution should have a positive impact on the performance of the application. By allowing the original stylesheet to remain in the <head>, we can avoid the need for redundant work and simplify the polyfill's functionality. This should result in faster page loads and improved overall performance.
Q: What are the potential drawbacks of the proposed solution?
A: While the proposed solution has several benefits, there are also some potential drawbacks to consider. These include:
- Additional development effort required to implement the solution
- Potential issues with the Turbo library if not implemented correctly
- Need for additional testing to ensure the solution works as expected
Q: How can I implement the proposed solution in my application?
A: To implement the proposed solution, you will need to modify the Anchor Polyfill to leave the original stylesheet in the <head> and only add the polyfilled styles as needed. You will also need to develop a mechanism for tracking changes to the assets and determining when a full page reload is necessary.
Q: What are the next steps in implementing the proposed solution?
A: The next steps in implementing the proposed solution involve:
- Modifying the Anchor Polyfill to leave the original stylesheet in the
<head> - Developing a mechanism for tracking changes to the assets and determining when a full page reload is necessary
- Testing the solution to ensure it works as expected
Conclusion
In conclusion, the proposed solution to issue of the Anchor Polyfill and Turbo is a simple yet effective one. By allowing the original stylesheet to remain in the <head>, we can avoid redundant work and simplify the polyfill's functionality. This approach also provides a more elegant solution to the problem and ensures that the original stylesheet remains present in the <head>.
