How to Use Remote Images in Vue3 with Webpack: A Complete Guide

Porting PHP projects to Vue3 can be a tricky business, particularly when it comes to handling images that are not stored locally. This common challenge arises when you have hundreds or thousands of images available remotely but don't want to download all of them to your project. In this post, we will explore a practical solution to facilitate the use of remote images in your Vue3 applications. Let’s dive into the problem, understand the errors involved, and uncover the steps needed to make remote images work seamlessly in your Vue3 environment.

Understanding the Problem

When developing your Vue3 app, you might encounter a specific error as you try to include remote images. For instance, you might see an error message similar to this:

This issue typically arises from the Webpack configuration looking for images in the local assets folder, while their actual location is external (remote). The code an example of what it might look like in your stylesheet:

Solution Overview

Fortunately, you can resolve this issue by leveraging environment variables in your Vue3 project. This allows you to configure different image paths for development and production environments without altering the core of your code. Let's break down the solution into clear, actionable steps.

Step-by-Step Solution

Create Environment Files

In the root directory of your Vue3 project (where vue.config.js resides), create two files: .env.development and .env.production.

Populate those files as follows:

.env.development:

Additional Information

You may wonder why you need to write environment variables into a SCSS file. The reason is to avoid warnings in your IDE, especially if you use tools like PHPStorm, which may not recognize the variables unless they are explicitly defined.

If you want to minimize the number of environment variables used in your SCSS files, you can target specific variables prefixed with VUE_APP_SCSS_:

Conclusion

By following this guide, you can effectively manage remote images in your Vue3 projects using environment variables, thus saving time and effort when deploying your application. You’ll no longer need to download all those images, and your code remains clean and maintainable. Embrace the power of Webpack and Vue3 together for a seamless development experience!
