Script Usage

npm install

src/fetchemail.js

create .env file with params for your Email provider

   emailusername=xxx
   emailpassword=xxx
   emailhost=xxx
   emailport=xxx

Run File with

node src/fetchemail.js

Then send an email to same email address and email will be saved out to local file system on receipt, this gives you a real world example of am decoded email.

src/parseemail.js

Edit parseemail.js to edit constants

• lowerbound: lower limit number to reject a email data value, note rest of email still parsed.
• upperbound: upper limit number to reject a email data value, note rest of email still parsed.
• emailwhitelist: Only emails in this array will be parsed.

//const for some basic input input validation
const lowerbound = 0
const upperbound = 20000
const emailwhitelist = ['waterfall_matthew@hotmail.com', 'matthew@waterfall-family.co.uk']

To parse the received email create file called test.js with the following code

const parseEmail = require('./parseemail.js')
// Make sure we got a filename on the command line.
if (process.argv.length < 3) {
    console.log('Usage: node ' + process.argv[1] + ' FILENAME');
    process.exit(1);
}
// Read the file and send to parseEmail
var fs = require('fs')
    , filename = process.argv[2];
fs.readFile(filename, 'utf8', function (err, data) {
    if (err) throw err;
    console.log('OK: ' + filename);
    // console.log(data)
    parseEmail(data).then(parseddata => {
        console.log(parseddata)
    })
})

To Do

1. Extend Test Cases more conplex and not repeating same 3 line
2. Configure Tape for automated testing - WIP npm run unit:test currently failing on test 4
3. Refactor(break & continue) for loop in parseemail.js
4. add email whitelisting to fetchemail script also.
