Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (springify) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Basic usage

import { Springify } from 'springify';

const spring = new Springify();

// Subscribe to updates. This will fire every frame and pass through the current values.
spring.subscribe(({ output, velocity }) => {
  // output is the output value from the spring
  // velocity is the velocity our spring is moving at
  console.log(output);
  console.log(velocity);
});

// Subscribe to the end event when the spring settles. This will fire once each time the spring stops.
spring.subscribe(({ output }) => {
  // output is the output value from the spring once it has settled
  console.log(output);
}, 'end');

// Update the value and springify will beging animating from the initial input value to the new one.
spring.input = 500;
