Master Nginx: Rewriting Language URIs for Image Files

When setting up a multilingual web application, ensuring that resources such as images and stylesheets load correctly can be a bit challenging, especially if you're new to web server configurations. If you've been getting 404 errors while trying to access images via language-specific paths like /es/image.png or /en/image.png, you're not alone. Many people run into this issue when deploying applications using Nginx. But fear not! In this guide, we'll walk through how to solve this problem and streamline your Nginx configuration.

The Problem

When you attempt to access /es/Inicio or /en/Index, the server mistakenly looks for images under the subdirectory /es/ or /en/ instead of the root directory. This results in 404 errors because it cannot find the image files in those paths.

For example:

The browser sends a request like GET /es/sp.svg, but the desired path is actually GET /sp.svg.

Why Does This Happen?

This issue stems from how the image paths are defined in your HTML. If your image paths are relative (like src="./image.png"), they will naturally prepend the current URI, causing the server to look under the wrong directory.

Solution: Rewrite Language URIs

Step 1: Fix Path Definitions

The first step to addressing this issue is to ensure that the image paths in your HTML use absolute paths instead of relative ones.

Step 2: Modify Nginx Configuration

If you prefer to keep the existing paths or if there are many files to manage, modifying your Nginx configuration is the way to go. Here's how to rewrite the URLs appropriately.

Locate Your Language-Specific Locations:
You already have configurations for /es/ and /en/. You'll be updating these to handle image requests effectively.

Update Your try_files Directives:
Add a rewrite rule to strip the language prefix from the URI before it tries to locate the image files.

Modified Nginx Configuration:

Breakdown of the Configuration

The location ^~ directive ensures that any URIs starting with /es/ or /en/ will trigger these blocks.

The @ rewrite location block is called whenever an image is requested under a language prefix.

The rewrite line strips away the language part, allowing the image file to be served from the root level where it actually resides.

Conclusion

Implementing language-specific URL rewrites in Nginx can be straightforward once you understand the importance of correct path definitions and how to configure your server. By following the steps outlined above, you will resolve your current issues with 404 errors related to image loading and streamline the functioning of your multilingual web application.
