Fixing the Image Display Issue in Swift Vapor 4 with Leaf

When working on web applications using Swift Vapor 4 and the Leaf templating engine, it can be frustrating to encounter issues such as images not displaying properly. You're not alone if you've found that the browser only shows the text provided in the alt attribute instead of rendering the image itself. This guide will guide you through the common pitfalls and provide a clear solution to ensure your images are displayed correctly.

The Problem: Image Not Displayed

Upon creating a static Leaf page designed to showcase an image, you may have encountered a situation where the image fails to render in the browser. Instead, the value of the alt attribute appears. This issue can stem from a minor error in your HTML code; specifically, a typo in the attribute meant to specify the image source.

Common Signs of the Issue:

Image URLs entered correctly but still not visible.

The browser displays the alt text instead of the image.

Static HTML pages in Leaf not rendering images.

Solution: Correct the Attribute Name

The core of the issue lies in a spelling mistake; it often happens to the best of us! Let’s break it down into actionable steps to fix it.

Step 1: Identify the Typo

In the provided code example, the typo lies in the <img> tag. Instead of using scr for the source attribute, the correct term should be src. Here's the incorrect line of code:

[[See Video to Reveal this Text or Code Snippet]]

Step 2: Correct the HTML Code

To rectify the issue, simply change scr to src. The corrected code should look like this:

[[See Video to Reveal this Text or Code Snippet]]

Step 3: Test in Browser

Once you've made the correction in your code, save the changes and refresh your page in the browser. With the src attribute correctly specified, you should now see the image rendered perfectly.

Conclusion

By ensuring that you check for simple compilation mistakes like typos, you can save time and frustration when working on web applications. In this case, correcting scr to src in the <img> tag solved the issue of the image not displaying on your Swift Vapor 4 application using Leaf.

Key Takeaway

Whenever images do not display as expected, always revisit your HTML code for small errors. They can make a significant impact on how the elements are rendered in your application.

With these adjustments, you should now be well-equipped to showcase images successfully in your Swift Vapor applications. Happy coding!
