How to Set a Default Image Using Vuex Store in Your Vue.js Application

In the world of web development, having a default image for user profiles is a common feature that many applications require. However, when working with frameworks like Vue.js, developers may encounter challenges while trying to dynamically set images through the Vuex store. In this guide, we will explore a problem that a developer faced while setting a default image using Vuex and provide a clear, step-by-step solution to ensure you can implement this feature in your own applications.

The Problem

Imagine you are building a Vue.js application where you want to display a default user image. You decide to manage your application's state using Vuex. Here's the initial setup you might have:

In your App.vue, you attempt to display the image as follows:

However, this setup does not work as expected. The <img> tag in your template does not display the image. When you hard-code the path directly in the src attribute, everything works fine. You may find yourself wondering, Why is this happening?

The Solution

The issue lies in how Vue handles image paths. When you retrieve an image path from the Vuex store, you need to tell Vue that the path is dynamic. Here’s how you can do it:

Step 1: Modify the Image Source Binding

Instead of using the src attribute directly with the Vuex getter, you should use the require function within a template literal to dynamically resolve the image path. Update the src attribute as follows:

Step 2: Explanation of the Change

Using require() allows Webpack (the module bundler for Vue.js applications) to recognize that the image is a dynamic asset. Here's why this works:

Webpack Handling: When you use require, Webpack bundles all the assets and knows how to optimize them. By doing this, you allow Webpack to resolve the path at build time, ensuring that it can correctly locate your image.

Dynamic Path Resolution: Template literals allow for the interpolation of variables, making it possible for require to evaluate the path from the Vuex store dynamically.

Final Code Implementation

Here is how your final implementation would look in the App.vue component:

Conclusion

Managing state with Vuex and displaying images dynamically can pose challenges, but with a few adjustments, you can achieve the desired outcome without complications. By incorporating the require function to reference images stored in your Vuex state, you ensure that your application retrieves the right assets effectively.

Feel free to implement this solution in your Vue.js applications and enhance your user experience with default images for user profiles!
