Creating Reusable Components with Vue and Pinia

In the world of modern web development, creating reusable components is key to building efficient and maintainable applications. If you're using Vue and Pinia for state management, you might encounter situations where you want to have multiple instances of a component sharing unique state without interference. In this post, we’ll explore how to build a reusable Table component that utilizes Search and Records components while managing state effectively to avoid conflicts.

The Problem: Managing State with Multiple Instances

You need to build a Table component that displays Orders and Customers, each requiring their own search functionality. However, when you type in one search bar, the other table unintentionally reflects the same search input. This situation can lead to confusion and is not user-friendly.

Here's a quick rundown of the components in play:

Search component: Captures the user's input for searching records.

Records component: Displays records based on the search input.

Table component: Wraps Search and Records.

Pinia store: Manages the search state across components.

Let’s take a look at how we can modify the setup to achieve our desired functionality.

The Solution: Encapsulating State within the Table Component

Step 1: Remove Shared State Management from Pinia

Instead of relying on a global store for the search state (the Pinia store isn't necessary in most cases for this functionality), we can encapsulate the search value within the Table component itself. This means each Table instance will manage its unique search state.

Here’s the modified code implementation:

Step 2: Modify Search Component to Use Props

Update your Search.vue component to accept the search value as a prop instead of using the Pinia store directly.

Step 3: Update Records Component to Accept Prop

Your Records.vue component will also need to be updated to accept the search value as a prop. This ensures that it displays the correct records based on the specific instance's search input.

Conclusion: Streamlining Context with Encapsulation

By encapsulating the search state within the Table component and passing it down to the Search and Records components via props, we achieve a clean and effective solution that allows multiple instances of the Table component to operate independently.

This approach simplifies the architecture by reducing dependency on a global store like Pinia, which is often overkill for managing local state. It enhances component reusability and maintainability while keeping your application performant.

Final Thoughts

Next time you're building reusable components in Vue, remember that not everything needs to live in a global state. Sometimes, local encapsulation is the best approach for clean, maintainable code.

With this method, you can easily extend your application with more tables or complex features without introducing unnecessary complexity. Happy coding!
