PostCSS Easings

PostCSS plugin to replace easing name from easings.net to cubic-bezier().

.snake {
  transition: all 600ms ease-in-sine;
}
.camel {
  transition: all 600ms easeInSine;
}

.snake {
  transition: all 600ms cubic-bezier(0.47, 0, 0.745, 0.715);
}
.camel {
  transition: all 600ms cubic-bezier(0.47, 0, 0.745, 0.715);
}

Usage

Step 1: Install plugin:

npm install --save-dev postcss postcss-easings

Step 2: Check your project for existed PostCSS config: postcss.config.js in the project root, "postcss" section in package.json or postcss in bundle config.

If you do not use PostCSS, add it according to official docs and set this plugin in settings.

Step 3: Add the plugin to plugins list:

module.exports = {
  plugins: [
+   require('postcss-easings'),
    require('autoprefixer')
  ]
}

Also, you can get all built-in easings:

require('postcss-easings').easings;

Options

easings

Allow to set custom easings:

    require('postcss-easings')({
      easings: { easeJump: 'cubic-bezier(.86,0,.69,1.57)' }
    })

The plugin will convert custom easing name between camelCase and snake-case. So the example below adds easeJump and ease-jump easings.

Custom easing names must start from ease and contain only letters and -.

You can create custom easing on cubic-bezier.com.
