Sending email with API in node js

Question

I've been trying to create an web application which sends welcome email to its new subscribers. from over one week i am just stuck at one problem, my console doesn't show any output, no success or fail of email sent. I've checked my API code and it works perfectly, tried everything but don't know why terminal is just not responsive I try node server.js in my terminal and it says server running on port 3000, i navigate to local host 3000 through my browser and try hitting subscribe after entering my email and no updates in my terminal

const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const axios = require('axios');

app.use(bodyParser.json());

app.get('/', (req, res) => {
  res.sendFile(__dirname + '/index.html');
});

// trying to create a server to send emails to users who click subscribe button

app.post('/send-welcome-email', async (req, res) => {
    const { email } = req.body;

    const emailData = {
        From: 'sgarak@deakin.edu.au',
        To: email,
        Subject: 'Welcome to DevLink',
        HtmlBody: '<html><head></head><body><p>Welcome to DevLink, thanks for jooining our platform!</p></body></html>'
    };

    try {
        const response = await axios.post('https://api.postmarkapp.com/email', emailData, {
            headers: {
                'Authorization': `MY_API_TOKEN`,
                'Accept': 'application/json',
                'content-type': 'application/json'
            }
        });
        res.status(200).send('Email sent');
    } catch (error) {
        console.error(error);
        res.status(500).send('Something went wrong');
    }
});

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => console.log(`Server running on port ${PORT}`));

What errors do you get in the browser console ... CORS errors? There's no hint that you allow any CORS in your server code, and there will definitely be a preflight request since you're using JSON body parser i.e. you're sending json data — Jaromanda X, Aug 17 '23 at 05:32
Did you check your api on Postman that rather its working or not? — Rai Hassan, Aug 17 '23 at 05:35
POST command shows nothing as well, looks like terminal is just non responsive, no errors at all, nothing — Somil, Aug 17 '23 at 05:55
Re: I am not sure how to check browser console errors Developer tool (i.e. for chrome: Ctrl+Shift+i) -> Console tab — Asad, Aug 17 '23 at 05:58
Don't use bodyParser. Use app.use(express.json()); app.use(express.urlencoded({ extended: true })); — digitalniweb, Aug 17 '23 at 06:02
@digitalniweb it throws error when trying to start server ReferenceError: bodyParser is not defined — Somil, Aug 17 '23 at 06:06
I could see some problem in browser console, i'll share image in the post — Somil, Aug 17 '23 at 06:11
Please research those error messages, you are not the first person ever to encounter them. — CBroe, Aug 17 '23 at 06:15

Your screenshot shows that you are trying to make the HTTP request to your server by running curl in the same terminal as you are running your server using node.

Because the terminal is running node, it isn't accepting new shell commands, so curl isn't running.

You need to run curl in a different terminal.
