Introduction

Have you ever shared a link on social media and noticed that the preview image doesn't appear correctly? This can be frustrating, especially when you want your content to make a good first impression. In this article, we'll delve into a specific case where the preview image of a portal was broken on social media platforms due to a website redesign. We'll explore the problem, the steps to reproduce it, and the proposed solution. Understanding these issues and how to address them can significantly improve the user experience and ensure your content is displayed correctly across various platforms. This is especially important for businesses and individuals who rely on social media to drive traffic and engagement.

Understanding the Issue: Broken Preview Images

When you share a link on social media platforms like Facebook, Twitter, Slack, or Discord, these platforms fetch metadata from the linked webpage to generate a preview. This preview typically includes a title, description, and a preview image. The preview image is crucial as it visually represents the content and can significantly impact click-through rates. A broken or missing preview image can make your link look unprofessional and less appealing, potentially reducing the number of people who click on it.

The specific issue we're addressing here is that the preview image for a portal was no longer appearing when sharing its link on social media. This problem arose due to a redesign of the main website. Website redesigns often involve changes to the structure and content of the site, which can inadvertently affect elements like the preview image if not properly addressed. It's essential to understand how these changes can impact social media previews and how to rectify them.

The Technical Details: How Social Media Previews Work

Social media platforms use web crawlers, often referred to as social media bots, to access and interpret the metadata of a webpage. This metadata is typically found in the HTML <head> section of the page. Specific meta tags, such as og:image, og:title, and og:description, are used to define the preview image, title, and description, respectively. These tags are part of the Open Graph protocol, a standard used by social media platforms to understand the content of a webpage.

When a link is shared, the social media platform's crawler visits the URL, parses the HTML, and looks for these Open Graph meta tags. If the og:image tag is missing, incorrect, or pointing to a broken link, the platform may display a default image, a broken image icon, or no image at all. This is why it's crucial to ensure that these meta tags are correctly implemented and that the image URL is valid.

In the case of the broken portal preview image, the issue stemmed from an outdated image URL specified in the og:image meta tag. The website redesign likely involved changes to the file structure or the location of images, rendering the old URL invalid. To fix this, the og:image tag needed to be updated to point to the new location of the preview image.

Reproducing the Issue: A Step-by-Step Guide

To effectively address any technical issue, it's essential to be able to reproduce it consistently. This allows developers to verify the problem and test potential solutions. In this case, the steps to reproduce the broken preview image issue are quite straightforward:

  1. Share the Hemi Link: The first step is to simply share the link to the portal on any social media platform. This could be Facebook, Twitter, Slack, Discord, or any other platform that supports link previews.
  2. Observe the Preview: After sharing the link, observe the preview that is generated by the social media platform. If the issue is present, you will notice that the preview image is either missing, broken, or displaying a default image instead of the intended preview image.

By following these steps, anyone can reproduce the issue and confirm that the preview image is indeed broken. This is the first step in the troubleshooting process and helps to validate that the problem exists.

The Root Cause: Outdated Image URL

As mentioned earlier, the root cause of the broken preview image was an outdated image URL in the og:image meta tag. This tag, located in the <head> section of the portal's HTML, specifies the URL of the image to be used as the preview. After the website redesign, the location of the image file changed, but the og:image tag was not updated accordingly.

The specific line of code that needed to be updated was found in the layout.tsx file of the ui-monorepo repository. The original code pointed to an old image URL that was no longer valid. This highlights the importance of keeping metadata consistent with website changes. Whenever a website undergoes a redesign or structural update, it's crucial to review and update all relevant meta tags to ensure they accurately reflect the current state of the site.

Proposed Solution: Updating the Image URL

The proposed solution to fix the broken preview image was to update the image URL in the og:image meta tag. This involved identifying the correct location of the new preview image and modifying the layout.tsx file to reflect this change.

The specific steps to implement this solution are as follows:

  1. Identify the New Image URL: The first step is to locate the new preview image and determine its URL. This might involve browsing the website's file structure or using developer tools to inspect the image element.
  2. Modify the layout.tsx File: Once the new image URL is identified, the next step is to update the og:image meta tag in the layout.tsx file. This can be done by opening the file in a text editor and replacing the old URL with the new one.
  3. Test the Changes: After updating the URL, it's essential to test the changes to ensure that the preview image is now displaying correctly. This can be done by sharing the portal link on social media and observing the generated preview.

By following these steps, the broken preview image issue can be resolved, ensuring that the portal link displays correctly on social media platforms. This simple fix can significantly improve the user experience and the overall presentation of the portal's content.

Implementing the Fix: A Practical Guide

To implement the fix, you'll need to access the codebase and modify the relevant file. In this case, the file is layout.tsx within the ui-monorepo repository. Here's a more detailed guide:

  1. Access the Repository: Gain access to the ui-monorepo repository. This usually involves cloning the repository to your local machine or accessing it through a web-based interface like GitHub or GitLab.
  2. Locate the layout.tsx File: Navigate to the portal/app/ directory within the repository and locate the layout.tsx file. This file likely contains the layout structure for the portal application, including the <head> section where meta tags are defined.
  3. Open the File in a Text Editor: Open the layout.tsx file in your preferred text editor. This could be a code editor like Visual Studio Code, Sublime Text, or Atom.
  4. Find the og:image Meta Tag: Search for the og:image meta tag within the file. This tag will typically look something like this:
    <meta property="og:image" content="[old_image_url]" />
  5. Replace the Old URL with the New URL: Replace the [old_image_url] with the correct URL of the new preview image. Make sure the URL is accurate and points to the correct image file.
  6. Save the Changes: Save the changes to the layout.tsx file.
  7. Commit and Push the Changes: Commit the changes to the repository and push them to the remote branch. This will deploy the updated code to the live environment.
  8. Test the Fix: After deploying the changes, test the fix by sharing the portal link on social media and verifying that the preview image is now displaying correctly.

By following these steps, you can effectively implement the fix and resolve the broken preview image issue. Remember to always test your changes thoroughly to ensure they are working as expected.

Verifying the Solution: Testing and Validation

After implementing the fix, it's crucial to verify that the issue has been resolved and that the preview image is now displaying correctly on social media platforms. This involves testing and validation steps to ensure the solution is effective.

Here are some methods to verify the solution:

  1. Share the Link on Social Media: The most straightforward way to test the fix is to share the portal link on various social media platforms, such as Facebook, Twitter, Slack, and Discord. Observe the generated preview on each platform to ensure the preview image is displaying correctly.
  2. Use Social Media Debugging Tools: Social media platforms often provide debugging tools that allow you to preview how a link will appear when shared. For example, Facebook has the Sharing Debugger, and Twitter has the Card Validator. These tools can help you identify any issues with your metadata and ensure that the preview image is being fetched correctly.
  3. Inspect the HTML Source: You can also inspect the HTML source of the portal page to verify that the og:image meta tag is correctly implemented and that the URL points to the correct image. This can be done using the developer tools in your web browser.

By using these methods, you can confidently verify that the solution has been implemented correctly and that the broken preview image issue has been resolved. Thorough testing and validation are essential to ensure a smooth user experience and prevent future issues.
