Limiting local storage Items in an Angular GitHub Search App

When building a GitHub search application with Angular, managing data storage efficiently is crucial for better user experience. One common requirement is to limit the maximum number of items a user can save to local storage. In this guide, we will explore how to implement such a limitation in your application, specifically enforcing a maximum of 5 items.

Problem Overview

Imagine a scenario where users can save their favorite GitHub profiles. If users are allowed to save unlimited profiles, the favorite list can become cluttered and difficult to manage. To tackle this problem, we want to ensure that no more than 5 items can be stored in the local storage. Additionally, we could disable or hide the “Add to Favorite” button if a user attempts to add more than 5 favorites.

Proposed Solution

To achieve this functionality, we’ll create a simple check in our Angular component's TypeScript code and HTML template. Here’s a step-by-step breakdown of the implementation:

Step 1: Set Up Local Storage Check

In your component (e.g., home.component.ts), you’ll want to check how many items are currently stored in local storage. This can be done as follows:

Step 2: Modify the HTML Template

Next, we need to update the HTML template to hide or disable the "Add to Favorite" button based on the number of items in local storage. Here’s how you can do this:

This line uses Angular's *ngIf directive to conditionally render the button only if the number of items in local storage is less than 5.

Final Implementation

Here is the combined code in context of your existing application components:

Conclusion

Limiting the number of items stored in local storage is a straightforward process that greatly enhances the usability of your application. By following the steps outlined above, you can efficiently manage user favorites in your Angular GitHub search app. Not only does this prevent overwhelming the user with too many options, but it also ensures a cleaner, more intuitive experience.

Implement this feature in your own projects to keep your application's storage organized and user-friendly! Remember, a well-structured application is key to user satisfaction.
