Step 3 – Install express ejs body-parser mysql Modules

Run the following command on the cmd to install express ejs body-parser MySQL modules:

npm install express ejs mysql body-parser --save

Step 4 – Connect the App to DB

Create database.js file in your app root directory, and add the following code in it:

var mysql = require('mysql');
var conn = mysql.createConnection({
host: 'localhost', // Replace with your host name
user: 'root',      // Replace with your database username
password: '',      // Replace with your database password
database: 'my-node' // // Replace with your database Name
}); 
conn.connect(function(err) {
if (err) throw err;
console.log('Database is connected successfully !');
});
module.exports = conn;

Step 5 – Create Server.js File And Import Modules

Create server.js file in the application root directory, and import above-installed modules into it:

var createError = require('http-errors');
var express = require('express');
var path = require('path');
var bodyParser = require('body-parser');
var db = require('./database');
var app = express();

Step 6 – Create HTML Markup Form

Create index.html file, and add HTML input field in it and implement ajax code to search data from apis:

<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Node js MySQL Autocomplete Search - Tutsmake.com</title>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.css" />
<script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="dsp container">
<div class="row dsp">
<h2>Node js Autocomplete Search with MySQL</h2>
<input type="text" name="search-google" id="search-google" placeholder="find any country..." class="form-control litanswer">
</div>
</div>
<script type="text/javascript">
$(function() {
$("#search-google").autocomplete({
name: 'search-google',
source: 'http://localhost:3000/search?key=%QUERY',
limit: 4
});
});
</script>
</body>
</html>

Step 7 – Create Routes

Create routes in server.js file, and add the following code in it:

var createError = require('http-errors');
var express = require('express');
var path = require('path');
var bodyParser = require('body-parser');
var db = require('./database');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, '/'));
app.set('view engine', 'ejs');
app.get('/', function(req, res) {
res.render('index');
});
app.get('/search', function(req, res) {
db.query('SELECT country_name FROM countries WHERE country_name LIKE "%' + req.query.term + '%"',
function(err, rows, fields) {
if (err) throw err;
var data = [];
for (i = 0; i < rows.length; i++) {
data.push(rows[i].country_name);
}
res.end(JSON.stringify(data));
});
});
// port must be set to 8080 because incoming http requests are routed from port 80 to port 8080
app.listen(3000, function() {
console.log('Node app is running on port 3000');
});
module.exports = app;

Step 7 – Test Application

You can use the following command to start node js app server:

//run the below command
npm start
after run this command open your browser and hit 
http://127.0.0.1:3000/
