How to use the mjml-core.helpers.widthParser function in mjml-core

getMobileWidth () {
    const { mjAttribute, sibling, parentWidth, mobileWidth } = this.props
    const width = mjAttribute('width')

    if (mobileWidth != "mobileWidth" ) {
      return '100%'
    } else if (width == undefined) {
      return `${parseInt(100 / sibling)}%`

    const { width: parsedWidth, unit } = helpers.widthParser(width)

    switch (unit) {

        return width
      case 'px':
      default:
        return `${parsedWidth / parentWidth}%`
    }
  }

    const { mjAttribute, sibling } = this.props
    const width = mjAttribute('width')

    if (width == undefined) {
      return `mj-column-per-${parseInt(100 / sibling)}`
    }

    const { width: parsedWidth, unit } = helpers.widthParser(width)

      case 'px':
      default:

    }
  }

uniq(columnWidths).forEach((width) => {
      const { width: parsedWidth } = helpers.widthParser(width, { parseFloatToInt: false })
      const mediaQueryClass = `${className}-${parseInt(parsedWidth)}`

      mediaQueries.push(`.${mediaQueryClass} { width:${parsedWidth}${unit}!important; }`)

    return (
