How to Implement a Search Functionality in Vue.js 3 for Filtering Data from an API

In the ever-evolving web development landscape, user experience becomes paramount to build robust and effective applications. One such critical feature is the ability to search for contextually relevant data. In this post, we will explore how to implement a search function in a Vue.js 3 application that allows users to filter houses based on their location or street names.

The Problem: Filtering Houses

Imagine you have an application that fetches a list of houses from an API, and you want users to be able to search for a specific house by typing in a street or a city name. Below is a simplified example of how your Vue component might look when it's set up to display houses, but currently lacks the search feature:

With the above code structure, houses are displayed, but the ability to filter through them dynamically by user input is missing.

The Solution: Using Computed Properties

To implement this search functionality, we can utilize Vue's computed properties. Computed properties allow us to declare a property that automatically updates when its dependencies change, making it perfect for creating a dynamic list based on user search input.

Steps to Implement the Search Functionality

Define a Search Property: In your component's data(), we will create a property to hold the search term.

Create a Computed Property to Filter Houses: This property will filter the houses array based on the user's input.

Bind the Computed Property in the Template: Rather than looping over houses, we will loop over our computed property.

Here's how we can change the code accordingly:

Updated Template Code

Here’s how to adjust the template to utilize the filteredHouses:

Summary of Changes

Added search as a data property to capture user input.

Introduced filteredHouses as a computed property to filter the houses based on the search term.

Updated the template to loop over filteredHouses instead of houses.

Conclusion

With the updates above, your Vue.js 3 application now has a functional search feature that allows users to dynamically filter houses based on their input. This not only improves the user experience but also adds great value to your application.

Feel free to explore more possibilities, modify the search criteria, and enhance your application's capability to meet your users' needs! Happy coding!
