Install
$ npm i chalk-animationUsage
const chalkAnimation = require('chalk-animation');
chalkAnimation.rainbow('Lorem ipsum dolor sit amet');Start and stop
You can stop and resume an animation with stop() and start().
When created, the instance of chalkAnimation starts automatically.
const rainbow = chalkAnimation.rainbow('Lorem ipsum'); // Animation starts
setTimeout(() => {
rainbow.stop(); // Animation stops
}, 1000);
setTimeout(() => {
rainbow.start(); // Animation resumes
}, 2000);Automatic stop
Anything printed to the console will stop the previous animation automatically
chalkAnimation.rainbow('Lorem ipsum');
setTimeout(() => {
// Stop the 'Lorem ipsum' animation, then write on a new line.
console.log('dolor sit amet');
}, 1000);Changing speed
Change the animation speed using a second parameter. Should be greater than 0, default is 1.
chalkAnimation.rainbow('Lorem ipsum', 2); // Two times faster than defaultChanging text
Change the animated text seamlessly with replace()
let str = 'Loading...';
const rainbow = chalkAnimation.rainbow(str);
// Add a new dot every second
setInterval(() => {
rainbow.replace(str += '.');
}, 1000);Manual rendering
Manually render frames with render(), or get the content of the next frame with frame()
const rainbow = chalkAnimation.rainbow('Lorem ipsum').stop(); // Don't start the animation
rainbow.render(); // Display the first frame
const frame = rainbow.frame(); // Get the second frame
console.log(frame);CLI mode
