SendGrid's new client library is way worse.

v2.js

var sendgrid = require('sendgrid')(process.env.SENDGRID_USERNAME, process.env.SENDGRID_PASSWORD)

sendgrid.send({
    to: 'test@example.com',
    from: 'test@example.com',
    subject: 'Hello World from the SendGrid Node.js Library',
    text: 'some text here'
  }, function (err, json) {
    if (err) {
      res.status(500).json({ msg: 'Could not send feedback.' })
      return
    }
    res.status(202).json({ msg: 'Feedback accepted.' })
  })

v3.js

var helper = require('sendgrid').mail
from_email = new helper.Email("test@example.com")
to_email = new helper.Email("test@example.com")
subject = "Hello World from the SendGrid Node.js Library"
content = new helper.Content("text/plain", "some text here")
mail = new helper.Mail(from_email, subject, to_email, content)

var sg = require('sendgrid').SendGrid(process.env.SENDGRID_API_KEY)
var requestBody = mail.toJSON()
var request = sg.emptyRequest()

request.method = 'POST'
request.path = '/v3/mail/send'
request.body = requestBody
sg.send(request, function (response) {
  console.log(response.statusCode)
  console.log(response.body)
  console.log(response.headers)
})

The only thing better in the v3 client library is using API keys instead of a username / password. Everything else just looks uglier.

What the hell is an emptyRequest()? Why would we ever need to call it on our own, rather than have it be abstracted away by the library itself?

Just upgraded to the new Sendgrid node library and have to agree - it's Java-hell.

I literally googled "sendgrid api way worse"

And I get this gist subtitled "SendGrid's new client library is way worse." hahaha
