Import error using MjmlAdapter

[jaqarrick]

Description

When using the MjmlAdapter from the mailer module I get the following error when the compile function is invoked:

TypeError: (0 , mjml_1.default) is not a function

To Reproduce
In my email module imports I have the following

    MailerModule.forRootAsync({
      useFactory: () => ({
         ...
          adapter: new MjmlAdapter('ejs', {
            inlineCssEnabled: false,
          }),
         ...
    }),

When I call the mailerService.sendMail function the error is thrown.

Expected behavior
The function should successfully compile mjml to html

Suggested Solution
I would suggest updating the import statement here to

import * as mjml2html from 'mjml'

I've recreated the adapter locally outside of the package and this solution works.

Let me know if I'm missing something!

@juandav Thank you a lot!
When do you plan the release, pls? The last release was 3 years ago,... https://www.npmjs.com/package/@nest-modules/mailer
Thank you!

Hi @jaqarrick , I tested your PR, but for me works only import mjml2html = require('mjml') as a solution from this issue mjmlio/mjml#2430 or mjmlio/mjml#1387 (comment)
How did you achieve working it with import * as mjml2html from 'mjml'?
Thank you!

Did you solve it? @bebjakub

@carlos3g I duplicated MjmlAdapter and imported mjml with import mjml2html = require('mjml');
