Le Poste

A simple interface to send emails.

Installation

To install this npm package do

npm i le-poste

Usage

This package is interesting if you are using a dependency injector like di-why, combined with dotenv to just plug the env variables and play. So this will describe usage along with these two packages.

Go to your usual loaders directory index.ts and import mailInjectionDict

// your-project/src/loaders/index.ts
import DiContainer from 'di-why';
// import any other dict elements ...
// and
import { mailInjectionDict } from 'le-poste';

const injectionDict = {
  // somePackageLoadDict,
  // etc.,
  // finally inject all le-poste's loaders into the main loadDict
  ...mailInjectionDict,
};

const di = new DiContainer({ logger, load: injectionDict });
export default di;

Now you can go anywhere in your code and import the index file above:

import di from `./loaders`;
try {
  await di.loadAll();
  const mailSend = di.get('mailSend');
  await mailSend({ subject: "le poste is open", text: "Tu reçois my message" });
} catch (e) {
  console.log('Some error occurred', e);
}

Lots of magic happening here, thanks to di-why and the mailInjectionDict we imported. That's why you need not pass user, password, port and transporter stuff in order to send a message.

A question emerges, how do we pass the connection data to mailSend ? We don't do it directly. Read on.

Passing connection info

In order to configure mailSend, we need to be using dotenv, or add some properties to process.env. They are the following:

MAIL_SMTP_HOST=mail.yourmailprovider.com
MAIL_SMTP_PORT=465
MAIL_FROM_NAME="Jean Jacques"
[email protected]
MAIL_ADMIN_TO_COMMA_LIST="Notify Me Aswell" <[email protected]>
MAIL_TO_COMMA_LIST="Le phare" <[email protected]>
MAIL_PASSWORD='s0meR4nd0mCh4r5'
