How to Effectively Truncate Long Text in Angular for Your News Table

As web applications grow in complexity, managing how content is displayed can become a challenge. One common issue developers face is dealing with long text strings that can cause overflow in tables or other UI components. This is particularly relevant when working on a news table in Angular where you want to maintain a clean and concise layout. In this post, we will tackle the problem of truncating long text in your Angular application gracefully.

The Problem

You have a news table displaying various news items but have encountered an issue when the text content of items is too lengthy. This overflow makes your user interface look cluttered and unprofessional. Your goal is to trim both the name and text attributes of each news item to a maximum of 20 characters, followed by an ellipsis (...) to indicate that additional text exists.

Example of Input and Expected Output

Input: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Output: aaaaaaaa...

You might have attempted to implement this directly in your news.ts, but encountered issues. Let's explore the correct approach to ensure your truncation is implemented effectively.

Solution Overview

We will achieve this by creating a utility function that will handle the truncation of strings based on a specified character count. We will then apply this function during the processing of news items after fetching them from the service.

Step-by-Step Implementation

Create the Truncation Function

You will need to define a utility function that takes a string and a desired maximum length, returning the truncated version with ellipsis if necessary. Here’s a sample function you can use:

Modify the getNews Method

Next, modify your getNews method to apply the newly created truncation function to the name and text fields of each news item upon retrieval. Here’s how you can do this:

Update Your HTML Template

Your current HTML template remains unchanged since the truncation has already been handled in the TypeScript code. Here’s the relevant part of your template for reference:

Conclusion

By implementing a simple truncation utility function, you can ensure that your Angular news table remains visually appealing and easy to navigate, even when faced with lengthy text strings. This approach enhances the user experience and keeps your interface clean.

If you encounter any challenges while implementing this solution, don’t hesitate to revisit your function or check how the news items are processed after fetching them. Happy coding!
