JavaScript check if an URL is http or https using check-more-types library

In this JavaScript tutorial we learn how to validate if a given string is an http or https using the http() and https() method of the check-more-types library.

Create the sample project

Firstly we create an empty project with the following command.

mkdir sample-project
cd sample-project
npm init -y

And install the check-more-types module using the following command.

npm install check-more-types --save

How to check HTTP URL in JavaScript

To check if a given URL is an HTTP URL or not we can use the http() method of check-more-types library. The method returns true if the provided URL starts with http://

In the sample-project directory create a new file named check-http.js as below.

check-http.js

var check = require('check-more-types');

console.log(check.http('http://toricode.com'));
console.log(check.http('https://toricode.com'));

Run the check-http.js file using the following command.

node check-http.js

true
false

How to check HTTPS URL in JavaScript

To check if a given URL is an HTTPS URL or not we can use the https() method of check-more-types library. The method returns true if the provided URL starts with https://

In the sample-project directory create a new file named check-https.js as below.

check-https.js

var check = require('check-more-types');

console.log(check.https('https://toricode.com'));
console.log(check.https('http://toricode.com'));

Run the check-https.js file using the following command.

node check-https.js

true
false

More examples of how to use the check.http() and check.https() method

check-http-example.js

var check = require('check-more-types');

var url = 'https://toricode.com';

if(check.http(url)) {
    console.log(url + ' is an HTTP URL');
} else {
    console.log(url + ' is not an HTTP URL');
}

if(check.https(url)) {
    console.log(url + ' is an HTTPS URL');
} else {
    console.log(url + ' is not an HTTPS URL');
}

Run the check-http-example.js file using the following command.

node check-http-example.js

https://toricode.com is not an HTTP URL
https://toricode.com is an HTTPS URL

Happy Coding 😊
