Creating Reusable External Functions in Vue.js

As web projects grow, it’s common to encounter repetition in your code. This is particularly true with components like navigation buttons that may appear in multiple places within your application. If you’re facing this issue in your Vue.js project, don’t worry! In this post, we’ll explore how to create reusable external functions that will help you streamline your code and improve maintainability.

The Problem: Repetitiveness in Navigation

Imagine you have a growing number of navigation buttons, such as Profile, Dashboard, Settings, Login, and Logout. As your application evolves, you realize that you are writing the same code multiple times across different components (like side menus or navbars). This can become cumbersome and leads to less maintainable code.

Solution: Centralizing Navigation Items

To solve this problem, you can create an external file that holds all your menu items and their properties. This allows you to import this file wherever needed, ensuring that you only have to maintain a single source of truth for your navigation items.

Step 1: Create the Menu Items File

Let’s start by creating a file named menuItems.js. This file will export an object containing your menu items and a method to filter them based on authentication states.

Step 2: Import the Menu Items into Your Component

Now that you have your menu items centralized, the next step is to import them into a Vue component where you want to display them. Let’s use the navbar component as our example.

Step 3: Filtering Based on Authentication

To control which menu items are displayed, you can leverage Vuex to handle the authentication state. This enables components to react to changes in authentication seamlessly.

In your component, you might want to use Vuex’s mapGetters to retrieve the current authentication state.

Displaying the Navigation Items

Once you’ve set up the filtering logic, you can now display the items conditionally based on the authentication state.

Conclusion

By creating reusable external functions and leveraging Vuex for state management, you can eliminate code redundancy in your Vue.js applications. Centralizing components like navigation items not only simplifies your code but also enhances maintainability, making it easier to implement changes down the line.

If you follow these steps, you’ll find that managing your Vue application becomes much more efficient and enjoyable. Happy coding!
