Syntax error in sample sendgrid node.js code, during run time.

[kiranshashiny]

Issue Summary

I am getting a Syntax error in mail.js when I copied the sample sendgrid code and tried to run it on my server

Steps to Reproduce

1. npm install @sendgrid/mail
2. exported environment variable SENDGRID_API_KEY in my bash environment
3. Copied the sample code

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
  to: 'test@example.com',
  from: 'test@example.com',
  subject: 'Sending with SendGrid is Fun',
  text: 'and easy to do anywhere, even with Node.js',
  html: '<strong>and easy to do anywhere, even with Node.js</strong>',
};
sgMail.send(msg);

Last step:
Run the code

# node sendgrid.js
/root/scripts/node_modules/@sendgrid/mail/src/mail.js:6
const {
      ^

Hello @kiranshashiny,

I believe this is not working for you because v6 of this SDK does not support Node v4.

Do you have access to a machine that uses Node v6 or higher?

With Best Regards,

Elmer

This is correct, the error is happening on a destructuring statement which is not supported in Node 4.

I upgraded to node 8.x and it works.

Closing the issue as the fix was to upgrade.
