Pinky Swear

a small node project for exploring Promise functionality added with ES6

---

Starting Up

1. pinky swear

2. install dependencies with yarn or npm install

yarn or npm install

3. run npm start to start the program

npm start

4. Start making and breaking those Promises by uncommenting out the blocks of code you'd like to run.

The async operations are created throughout the workshop by using the following promisified functions:

Promisified fs.readFile

return new Promise(function (resolve, reject) {
  fs.readFile(filePath, function (err, file) {
    if (err) {
      console.error('There\'s been a grevious error')
      return reject(new Error('there\'s no file there'))
    }
    resolve(file)
  })
})
}

and Promisified bufferToString

return new Promise(function (resolve, reject) {
  if (!buffer.length) {
    console.error('Doesn\'t look like much of anything to me...')
    return reject(new Error('buffer empty!'))
  }
  resolve(buffer.toString('utf8'))
})
}
