sendgrid-mail/lib/util.js

The easiest way to send mail with sendgrid.

const debug = require('debug')('sendgrid-mail:util')
const _ = require('lodash')

const parseList = commaSeparatedList => {
  const trim = s => s.trim()
  const nonEmpty = val => !_.isEmpty(val)
  return (commaSeparatedList || '').split(',').map(trim).filter(nonEmpty).map(parseEmail)
}

// supported formats are 'user@domain.tld' and 'Name <user@domain.tld>'
const parseEmail = emailAddress => {
  if (!emailAddress || emailAddress.length < 1) {
    debug(`${emailAddress} --> null`)
    return null
  }

  const emailRegExp = /(?:"?([^"]*)"?\s)?(?:<?(.+@[^>]+)>?)/
  const matchData = emailAddress.match(emailRegExp)

  if (!matchData) {
    debug(`${emailAddress} --> null`)
    return null
  }

  const retVal = { email: matchData[2] }

  if (matchData[1]) {
    retVal.name = matchData[1]
  }

  debug(`${emailAddress} --> ${inspect(retVal)}`)
  return retVal
}

const inspect = obj => require('util').inspect(obj, { depth: null })

module.exports = {
  parseList: parseList,
  parseEmail: parseEmail,
  inspect: inspect
}
