How to send an email using AWS in Node project - node.js

Question

My Angular app sends some data to a node server (app.js) via a POST request, the request body is then returned in the response.
I am now trying to send an email that contains this data sent in the request body.
Currently, I can read a HTML file to populate the email body, & then send the email but I need to replace that HTML file with the data sent in my req.body.
Here is what I have so far in app.js:
const express = require('express')
const app = express()
const bodyParser = require('body-parser')
app.post('/postData', bodyParser.json(), (req, res) => {
res.json(req.body)
readFile();
sendEmail();
})
app.listen(3000, () => console.log('Example app listening on port 3000!'))
var AWS = require('aws-sdk');
const fs = require('fs');
var params;
var htmlFileName = '/Users/myName/Desktop/test.html'
AWS.config.loadFromPath('config-aig.json');
const fromEmail = 'myName';
const toEmail = 'myName'
const subject = 'Test Email' + Date()
function sendEmail() {
// Create the promise and SES service object
var sendPromise = new AWS.SES({ apiVersion: '2010-12-01'}).sendEmail(params).promise();
sendPromise.then(
function (data) {
console.log('send email success');
}).catch(
function (err) {
console.error('error --> ', err, err.stack);
});
}
function readFile(callback) {
return new Promise(
function (resolve, reject) {
fs.readFile(htmlFileName, 'utf8',
function read(err, data) {
if (err) {
return reject(err)
}
else {
console.log('file read success');
return resolve(data);
}
})
}
)
}
readFile()
.then((res) => {
// Create sendEmail params
params = {
Destination: { /* required */
ToAddresses: [
toEmail,
]
},
Message: { /* required */
Body: { /* required */
Html: {
Charset: "UTF-8",
Data: res
}
},
Subject: {
Charset: 'UTF-8',
Data: subject
}
},
Source: fromEmail, /* required */
}
sendEmail();
})
.catch((err) => {
console.log('File Read Error : ', err)
}
)
Can someone please show me how I can replace my htmlFileName with the req.body?

I use ejs to template my email here is a code i frenquently use to send email !
If you have questions i would be glade to answer
const ejs = require('ejs');
const AWS = require('aws-sdk');
const mailcomposer = require('mailcomposer');
const config_aws = {
accessKeyId: '',
secretAccessKey: '',
region: 'eu-west-1',
expeditor: '',
limitExpeditor: 50
};
AWS.config.update(config_aws);
const ses = new AWS.SES();
async function sendAnEmail(
expeditor,
subject,
destinator,
body,
destinator_name = null,
bcc = null,
callback
) {
ejs.renderFile(
`${__dirname}/templates/template.ejs`,
{
destinator,
destinator_name,
subject,
body
},
(err, html) => {
if (err) return console.error(err);
const sesEmailProps = {
Source: config_aws.expeditor,
Destination: {
ToAddresses: [`${destinator}`]
},
Message: {
Body: {
Html: {
Charset: 'UTF-8',
Data: html
},
Text: {
Charset: 'UTF-8',
Data: html ? html.replace(/<(?:.|\n)*?>/gm, '') : ''
}
},
Subject: {
Charset: 'UTF-8',
Data: subject
}
}
};
if (bcc) {
sesEmailProps.Destination = {
ToAddresses: [`${destinator}`],
BccAddresses: bcc // ARRAY LIMIT OF 49
};
}
ses.sendEmail(sesEmailProps, (error, data) => {
if (error) console.error(error);
callback(error, data);
});
}
);
}
