fix: Correct TypeScript definitions

[notheotherben]

See #251 and notheotherben/sendgrid-ts-demo#1 for more details on what wasn't working.

This ensures that the following code works correctly:

import * as SendGrid from "sendgrid";

const sendGrid = SendGrid("MYAPIKEY");
``

Could you please explain how these changes fix the TypeScript definitions?

Thanks!

[thinkingserious]

I'm thinking this would be a breaking change. SendGrid is the expected case.

[notheotherben]

It is certainly a breaking change when it comes to the definition, however it corrects the definition to match the actual behaviour of the SendGrid JS library.

I've updated the interface above to include the rest of the library's exports as expected.

@spartan563,

Thanks for the quick turnaround on the fix! I just had a few points of clarification in the review. We should be able to merge this one quickly.

Could you please add an example using TypeScript in NodeJS ?

Hey,

Sorry to comment on a closed PR, but doesn't emptyRequest need to take an object as a parameter?

[notheotherben]

Yeah, you're correct - sorry I missed that, let me quickly throw together a new PR

[ss108]

I forked this and made a couple other changes to the definition: https://github.com/bloomtri/sendgrid-nodejs

The callback for the API method should be optional, and it needs to return a Promise. If those look good to you, then please incorporate them and I can delete that fork.

Thanks for getting to this so promptly!
