Creating a Job Alert System with Node.js and Twilio

Set up a Node.js application that uses Twilio's API to send SMS job alerts based on custom search criteria, helping developers find high-paying job opportunities quickly.

const http = require('http');
const express = require('express');
const bodyParser = require('body-parser');
const Twilio = require('twilio');

const twilioAccountSid = 'YOUR_TWILIO_ACCOUNT_SID'; // Replace with your Twilio account SID
const twilioAuthToken = 'YOUR_TWILIO_AUTH_TOKEN'; // Replace with your Twilio auth token
const twilioPhoneNumber = 'YOUR_TWILIO_PHONE_NUMBER'; // Replace with your Twilio phone number

const app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

const twilioClient = new Twilio(twilioAccountSid, twilioAuthToken);

app.post('/sendJobAlert', (req, res) => {
    const { phoneNumber, message } = req.body;

    twilioClient.messages
        .create({
            body: message,
            from: twilioPhoneNumber,
            to: phoneNumber
        })
        .then((message) => {
            console.log('Job alert sent:', message.sid);
            res.send('Job alert sent successfully.');
        })
        .catch((error) => {
            console.error('Error sending job alert:', error);
            res.status(500).send('Error sending job alert.');
        });
});

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

This Node.js code sets up an Express server and initializes the Twilio client with Twilio credentials. It then defines an endpoint '/sendJobAlert' that takes a phone number and a message from the request body to send an SMS alert using Twilio's API. Finally, it starts the server on a specified port.

This HTML code provides a basic form to input a phone number and a custom message for the job alert. It uses jQuery to handle the form submission and make an AJAX POST request to the '/sendJobAlert' endpoint when the form is submitted. The CSS styles simple form elements for better user experience.
