Node js Autocomplete Search with MySQL Database Tutorial

In this tutorial; you will learn how to create an autocomplete search input box or textbox in node js express with MySQL database using jQuery and Ajax.

How to Create Ajax Autocomplete Search in Node with MySQL

Steps to create autocomplete search functionality from MySQL database:

Step 1 – Create Node Express js App

Run the following command on cmd to create node js app:

mkdir my-app
cd my-app
npm init -y

Step 2 – Create a Database and Table

Create a database and table; so execute the following SQL query to create a database and table:

CREATE DATABASE my-node;
CREATE TABLE IF NOT EXISTS `countries` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `phone_code` int(5) NOT NULL,
    `country_code` char(2) NOT NULL,
    `country_name` varchar(80) NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=253 DEFAULT CHARSET=utf8;
INSERT INTO `countries` (`id`, `phone_code`, `country_code`, `country_name`) VALUES

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/
