Or require with CommonJS:

Parse single declaration:

parse('left: 0');

Output:

[
  {
    type: 'declaration',
    property: 'left',
    value: '0',
    position: {
      start: { line: 1, column: 1 },
      end: { line: 1, column: 8 },
      source: undefined
    }
  }
]

Parse multiple declarations:

parse('left: 0; right: 100px;');

Output:

[
  {
    type: 'declaration',
    property: 'left',
    value: '0',
    position: {
      start: { line: 1, column: 1 },
      end: { line: 1, column: 8 },
      source: undefined
    }
  },
  {
    type: 'declaration',
    property: 'right',
    value: '100px',
    position: {
      start: { line: 1, column: 10 },
      end: { line: 1, column: 22 },
      source: undefined
    }
  }
]

Parse declaration with missing value:

parse('top:');

Output:

[
  {
    type: 'declaration',
    property: 'top',
    value: '',
    position: {
      start: { line: 1, column: 1 },
      end: { line: 1, column: 5 },
      source: undefined
    }
  }
]

  {
    type: 'declaration',
    property: 'answer',
    value: '42',
    position: {
      start: { line: 1, column: 1 },
      end: { line: 1, column: 11 },
      source: undefined
    }
  }
]
