Motion helpers

Getting started

To install @rocketsoftware/motion in your project, you will need to run the following command using npm:

npm install -S @rocketsoftware/motion

If you prefer Yarn, use the following command instead:

yarn add @rocketsoftware/motion


@carbon/motion supports standard, entrance, and exit easing curves in two motion modes: productive and expressive. You can access these curves using either Sass or JavaScript.


@carbon/motion exports a carbon--motion function and carbon--motion mixin that you can use to access the value of a motion curve or include that curve as the transition-timing-function for a selector. To use these helpers, you can do the following in your project:

@import '@carbon/motion/scss/motion.scss';

.my-custom-selector {
  // Supplies the standard easing curve, using the productive mode by default
  transition-timing-function: carbon--motion(standard);

.my-custom-selector-v2 {
  // Supplies the standard easing curve, but with the expressive mode, on the
  // transition-timing-function property for this selector
  @include carbon--motion(standard, expressive);

Both the motion function and mixin support passing in the name of the motion curve and the mode you want to work in.


If you're using @carbon/motion as a JavaScript dependency, we export our easings and a function called motion that you can use. For example:

// CommonJS
const { easings, motion } = require('@carbon/motion');

You can also include this as a JavaScript module:

// ESM
import { easings, motion } from '@carbon/motion';

motion('standard', 'productive'); // Returns a string `cubic-bezier()` function
