Introduction to the Restore-Cursor API

In the realm of web development, providing a seamless user experience is crucial. One often overlooked aspect is the management of the cursor’s position. The restore-cursor API ensures that the cursor returns to its desired position, enhancing usability in text editing and command-line applications.

Basic Usage of Restore-Cursor

The restore-cursor API can be employed in various scenarios where maintaining cursor position is essential. Below are the primary methods and their corresponding code snippets:

Creating a Restore Point

Before moving the cursor, it’s vital to create a restore point:

 const cursor = require('restore-cursor'); cursor.save(); 

Restoring the Cursor Position

To return the cursor to the previously saved position:

 const cursor = require('restore-cursor'); cursor.restore(); 

Hiding and Showing the Cursor

Additionally, the API allows for hiding and showing the cursor, useful in situations where the cursor’s presence can be distracting:

 const cursor = require('restore-cursor'); cursor.hide(); // Execute some operations cursor.show(); 

Advanced API Usage

Resetting the Cursor

Resetting the cursor position restores it to the initial position after all operations are complete:

 const cursor = require('restore-cursor'); // Some code that manipulates cursor cursor.reset(); 

Customizing Cursor Behavior

You can customize the cursor behavior such as blinking, color changes, etc.:

 const cursor = require('restore-cursor'); cursor.blinking(); cursor.setBackgroundColor('blue'); cursor.setVisibility('hidden'); 

Example Application

To illustrate the use of the restore-cursor API, here is a sample application that employs various methods:

 const cursor = require('restore-cursor');
function simulateLongRunningTask() {
    console.log('Starting task...');
    cursor.hide();
    
    setTimeout(() => {
        console.log('Task in progress...');
        cursor.save();
        cursor.show();
        
        setTimeout(() => {
            cursor.restore();
            console.log('Task completed!');
            cursor.reset();
        }, 2000);
    }, 2000);
}
simulateLongRunningTask(); 

This simple application demonstrates saving, hiding, restoring, and resetting the cursor within a simulated task, improving user interaction and experience.

By leveraging the restore-cursor API, developers can ensure a smooth and user-friendly experience, maintaining the cursor’s position precisely where it needs to be.
