const PostUtils = require('./path/to/lib/post.js')

const prepareEventData = contentItem => {
  try {
    const postUtils = new PostUtils(contentItem)

    const event = contentItem && {
      ...contentItem,
      ...postUtils.combinePostSections()
    }

    // Find the "data" bodyText component, which is used to control date, link, etc
    const dataSection = (event.bodyTextSections || []).find(section => {
      if (section.body && section.body.indexOf('Date:') > -1) {
        return section
      } else {
        return false
      }
    })

    const data = {}
    const lines = dataSection ? dataSection.body.split('\n\n') : []

    lines.forEach(line => {
      const lineParts = [
        line.substring(0, line.indexOf(':')),
        line.substring(line.indexOf(':') + 1)
      ]

      data[lineParts[0].trim().toLowerCase()] = lineParts[1].trim()

      if (lineParts[1].trim().toLowerCase() === 'public') {
        data.isPublic = true
      }

      if (lineParts[1].trim().toLowerCase() === 'external') {
        data.isExternal = true
      }

      if (lineParts[0].trim().toLowerCase() === 'ticket info') {
        data.ticketInfo = lineParts[1].trim()
      }

      if (lineParts[0].trim().toLowerCase() === 'link') {
        data.link = lineParts[1].trim()
      }

      if (lineParts[0].trim().toLowerCase() === 'link text') {
        data.linkText = lineParts[1].trim()
      }

      if (lineParts[0].trim().toLowerCase() === 'event id') {
        data.eventId = lineParts[1].trim()
      }
    })

    const item = {
      title: event.title,
      slug: event.slug,
      subtitle: event.subtitleSection?.content,
      date: data.date,
      link: data.link,
      linkText: data.linkText,
      img: getImageUrl(event.primaryImage),
      isExternal: data.isExternal,
      isPublic: data.isPublic,
      ticketInfo: data.ticketInfo,
      eventId: data.eventId
    }

    return item
  } catch (error) {
    console.log('Error parsing event :> ', error)
    return null
  }
}

looks normal enough.

i'd probably put the function above into a lib/utils file or similar, rather than in the component. then when you have fetched the data, you can pass it into the above function and get back an object with the right properties for the promo
