PostCSS Nested

PostCSS plugin to unwrap nested rules like how Sass does it.

.phone {
    &_title {
        width: 500px;
        @media (max-width: 500px) {
            width: auto;
        }
        body.is_dark & {
            color: white;
        }
    }
    img {
        display: block;
    }
}

.title {
  font-size: var(--font);

  @at-root html {
      --font: 16px
    }
  }
}

will be processed to:

.phone_title {
    width: 500px;
}
@media (max-width: 500px) {
    .phone_title {
        width: auto;
    }
}
body.is_dark .phone_title {
    color: white;
}
.phone img {
    display: block;
}

.title {
  font-size: var(--font);
}
html {
  --font: 16px
}

Usage

postcss([ require('postcss-nested') ])

See PostCSS docs for examples for your environment.

Options

bubble

By default, plugin will bubble only @media and @supports at-rules. You can add your custom at-rules to this list by bubble option:

postcss([ require('postcss-nested')({ bubble: ['phone'] }) ])
/* input */
a {
  color: white;
  @phone {
    color: black;
  }
}
/* output */
a {
  color: white;
}
@phone {
  a {
    color: black;
  }
}

unwrap

By default, plugin will unwrap only @font-face, @keyframes and @document at-rules. You can add your custom at-rules to this list by unwrap option:

postcss([ require('postcss-nested')({ unwrap: ['phone'] }) ])
/* input */
a {
  color: white;
  @phone {
    color: black;
  }
}
/* output */
a {
  color: white;
}
@phone {
  color: black;
}

preserveEmpty

By default, plugin will strip out any empty selector generated by intermediate nesting levels. You can set preserveEmpty to true to preserve them.

.a {
    .b {
        color: black;
    }
}

Will be compiled to:

.a { }
.a .b {
    color: black;
}

This is especially useful if you want to export the empty classes with postcss-modules.
