eaze

Use it to ease values for n steps up to the value you define. Note that we skip 0.

import eaze, { easings } from 'eaze'

const values = eaze(2, {
  value: 1,
  easing: easings.linear,
})

// => [
//   [0.5],
//   [1]
// ]

Or use it to generate fancy, multi-layered box-shadows

import eaze, { easings } from 'eaze'

const eased = eaze(
  6,
  {
    // alpha
    value: 0.07,
    easing: [0.1, 0.5, 0.9, 0.5],
  },
  {
    // offset
    value: 100,
    easing: [0.7, 0.1, 0.9, 0.3],
  },
  {
    // blur
    value: 80,
    easing: [0.7, 0.1, 0.9, 0.3],
  }
)

const fixed = (num, precision = 1) =>
  parseFloat(num.toFixed(precision), 10).toString()

const shadow = `
  box-shadow:
    ${eased
      .map(values => values.map(num => fixed(num)))
      .map(
        ([alpha, offset, blur]) =>
          `0px ${offset}px ${blur}px rgba(0, 0, 0, ${alpha})`
      )
      .join(',\n')};
`

For convenience, we also export a bunch of easing values:

• linear
• ease
• easeIn
• easeOut
• easeInOut
• easeInSine
• easeOutSine
• easeInOutSine
• easeInCubic
• easeOutCubic
• easeInOutCubic
• easeInQuint
• easeOutQuint
• easeInOutQuint
• easeInCirc
• easeOutCirc
• easeInOutCirc
• easeInQuad
• easeOutQuad
• easeInOutQuad
• easeInQuart
• easeOutQuart
• easeInOutQuart
• easeInExpo
• easeOutExpo
• easeInOutExpo

Local Development

Below is a list of commands you will probably find useful.

npm start or yarn start

Runs the project in development/watch mode. Your project will be rebuilt upon changes. TSDX has a special logger for you convenience. Error messages are pretty printed and formatted for compatibility VS Code's Problems tab.

Your library will be rebuilt if you make edits.

npm run build or yarn build

Bundles the package to the dist folder. The package is optimized and bundled with Rollup into multiple formats (CommonJS, UMD, and ES Module).

npm test or yarn test

Runs the test watcher (Jest) in an interactive mode. By default, runs tests related to files changed since the last commit.

This project was bootstrapped with TSDX.
