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…)
