Autocomplete Search in Node JS + MySQL

Follow the below step and create autocomplete search in nodejs + express + MySQL using ajax jquery Bootstrap:

  • Step 1 – Create Node Express js App
  • Step 2 – Create Database and Table
  • Step 3 – Install express ejs body-parser mysql Modules
  • Step 4 – Connect App to MySQL DB
  • Step 5 – Create Server.js File And Import Modules
  • Step 6 – Create HTML Markup Form
  • Step 7 – Create Routes
  • Step 8 – Start App Server

Step 1 – Create Node Express js App

Execute the following command on terminal to create node js app:

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

Step 2 – Create Database and Table

Create database and table; so execute the following sql query to create 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;

Step 3 – Install express ejs body-parser mysql Modules

Execute the following command on the terminal to install express ejs body-parser MySQL modules:

npm install express ejs mysql body-parser --save

body-parser – Node.js request body parsing middleware which parses the incoming request body before your handlers, and make it available under req.body property. In other words, it simplifies the incoming request.

Express-EJS– EJS is a simple templating language which is used to generate HTML markup with plain JavaScript. It also helps to embed JavaScript to HTML pages

Mysql an open-source relational database management system (RDBMS).

Step 4 – Connect App to MySQL DB

Create database.js file into your app root directory and add the following code into it to connect your app to the mongodb database:

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; so visit your app root directory and create server.js file; Then 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 html form for inserting data into database; So visit views directory and create index.ejs file inside it. Then add the following code into it:

<!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; so visit app root directory and open server.js file; Then add the following create autocomplete search routes; as shown below:

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 – Start App Server

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/

Conclusion

Ajax autocomplete search in node js + MySQL; In this tutorial, you have learned how to create autocomplete search in node js express app using MySQL database.
