const express = require('express');
const app = express();
const mysql = require('mysql');
app.use(express.json());

const connection = mysql.createConnection({
    host: 'localhost',
    user: 'yourUsername',
    password: 'yourPassword',
    database: 'yourDatabase'
});

app.get('/data', (req, res) => {
    connection.query('SELECT * FROM yourTable', (error, results) => {
        if (error) throw error;
        res.json(results);
    });
});

app.listen(3000, () => {
    console.log('Server running on port 3000');
});

This code snippet sets up a basic Express server that interacts with your SQL database using JavaScript. By defining routes, you can easily handle requests and respond with data from your database.

This approach opens up flexibility in how you handle data while maintaining a smooth user experience.

Creating a REST API with Node.js

To begin, you will need to set up a server using Node.js. This involves installing Express, a popular framework for building web applications in Node.js. Start by creating your server file, then define routes that correspond to various data operations. Here’s a simple illustration:

const express = require('express');
const app = express();
const PORT = process.env.PORT || 3000;

app.use(express.json());

app.get('/api/data', (req, res) => {
    // Fetch data from database
});

app.post('/api/data', (req, res) => {
    // Add data to database
});

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

This foundational setup allows your API to handle requests and interact with a SQL database. As you build your API, ensure efficient handling of database connectivity and responses.

Fetching Data Using Fetch API in HTML

On the front end, the HTML Fetch API enables you to send requests to your newly created REST API. This allows for seamless data retrieval without reloading the entire page. You can use the Fetch API as shown in this example:

fetch('http://localhost:3000/api/data')
    .then(response => response.json())
    .then(data => {
        console.log(data);
        // Process the data in your HTML
    })
    .catch(error => console.error('Error fetching data:', error));

By incorporating the HTML Fetch API, users enjoy a responsive experience, providing you with the capability to manage database connectivity effectively. With clear API responses and structured data handling, you can create robust applications that cater to various needs.
