log-update 6.0.0

Log-update is a popular npm package that can be utilized for overwriting the previous output in the terminal. This feature is highly useful during the rendering of progress bars, animations, etc. Log-update provides a way to keep your command line interfaces (CLI) clean and uncluttered by managing outputs smartly.

To use log-update, you first need to install the package via NPM using the command npm install log-update. Once installed, you can import it into your JavaScript file using import logUpdate from 'log-update'; thereafter, you can use its functions to log to stdout or stderr or to clear or persist the logged output. For instance, for creating a rotating set of characters (like a loader), you might use it as follows:

import logUpdate from 'log-update';
const frames = ['-', '\\', '|', '/'];
let index = 0;
setInterval(() => {
	const frame = frames[index = ++index % frames.length];
	logUpdate(
`
        ♥♥
   ${frame} unicorns ${frame}
        ♥♥
`
	);
}, 80);

The official documentation for log-update is available directly in the readme file on the official GitHub repository. The readme provides a comprehensive guide to the API, explaining how to use each of the available methods like logUpdate(text…), logUpdate.clear(), logUpdate.done(), logUpdateStderr(text…), logUpdateStderr.clear(), logUpdateStderr.done(), and createLogUpdate(stream, options?). The examples section of the readme points to other repositories that use log-update, which could provide further insights into its practical applications.
