Mastering Load More Feature in Angular: A Step-by-Step Guide

Implementing the Load More functionality in Angular is essential for enhancing user experience by loading additional data on-demand. If you are developing a feature where users can load more items from an API with a button click, this guide is tailored for you!

The Problem: Loading More Items on Demand

When building web applications, you may need to display data in a paginated manner. The usual approach is to load only a limited set of items initially and fetch more as the user scrolls or clicks a button. This method preserves performance and enhances the user experience.

In this blog, we will explore how to create a button that loads 10 more items from an API each time it’s clicked.

Solution Overview

Step 1: Set Up the Service

To begin, you need a service that will handle API requests. This service will fetch data based on a limit that we will dynamically update:

HttpClient: It’s used here for making HTTP requests.

Dynamic Limit: The getdata method accepts a limit parameter, allowing you to fetch a specific number of users.

Step 2: Create the Initial Setup in Component

In your component, you will need to declare a variable to track how many items to load and the method to handle the button click.

limit Variable: Initializes the number of items to be loaded.

loadUsers Method: Calls the service and updates newdata with newly fetched users.

Step 3: HTML Structure with Load More Button

Next, let’s look at the HTML layout, which includes a table displaying user data and a button for loading more items:

Conclusion

By implementing this Load More functionality, you efficiently manage data loading according to user actions, significantly improving the experience on your web application.

Recap of Key Steps

Service Setup: Created a service to handle API requests.

Component Logic: Used a method to fetch and handle user data dynamically.

HTML Implementation: Created a user interface with a Load More button.

Now, whenever the user clicks the Load More button, an additional 10 items will be loaded from the API, enriching the data in your application without overwhelming the user.
