Sendgrid-nodejs: setApiKey is not a function using imports

[atellier]

Issue Summary

When I try to import the mail service, I have the following error:

mail_1.MailService.setApiKey is not a function

Example code

import {MailService} from '@sendgrid/mail';
MailService.setApiKey('myKey');

Technical details:

• sendgrid-nodejs Version: master (latest commit: [commit number])
• "@sendgrid/mail": "^6.3.1" in package.json
• ts-node v7.0.1, node v11.0.0, typescript v3.1.1

Any help or pointers would be great. Trying to use require() as documented gave me the error and new MailService() would not work either. Thanks!

I don't believe NodeJS (maybe in v11 it does) supports ES6 import style module imports, but rather CommonJS. But sounds like you may have tried CommonJS require as well. Also, I don't think we've tested under Node v11. The current supported environments are for Node 6, 7, 8.

Have you tried the example in our getting started?

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
  to: '[email protected]',
  from: '[email protected]',
  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);

EDIT: I just validated that the example I included above works in Node v11.

@atellier As far as I'm aware, this package is a NodeJS only one so any ES6+ import ... statement wouldn't be valid due to the fact that NodeJS modules export differently than ES ones.

And the current Node version (read v11) doesn't support ESNext's (probably ES10+ since it's already 2019) import() (which is only in stage 3).

And the example @aroach gave works well on Node 11 (I can provide evidence if needed).

As far as it's more like a speculation on my part, Node 12 (which will be released the 23rd April 2019, so around the same month where Node 6 will reach its end of life) will only support as far as ES9 went and perhaps some ES10 features (using the --harmony flag) but for now, import isn't in the stage where it's likely to be released in ES10.

Hello @atellier,

Please feel free to re-open if you still need some help.

I replaced
import {MailService} from '@sendgrid/mail';
with
import MailService from '@sendgrid/mail';
and everything worked as expected.

The typescript types are not kept up to date and it uses module.exports so to use the types:
"@sendgrid/mail": "^6.4.0",

import MailService from "@sendgrid/mail/src/mail";
