And import it as a CommonJS module:

const nzfunc = require('nzfunc');

Functions

Here is a description of how the functions work.

hasJsonStructure

The hasJsonStructure function checks the JSON structure of the received string.

let string = '{"a":"12","b":13,"c":null}';
if (nzfunc.hasJsonStructure(string) === true) {
	console.log('String have a JSON structure');
} else {
	console.log('String does not have a JSON structure');
}

getHASH

The getHASH function returns the hash of the passed string.

console.log(nzfunc.getHASH('Hello'));

getHMAC

The getHMAC function returns hash-based message authentication code.

console.log(nzfunc.getHMAC('Hello', 'sha256', 'secret'));

isUrlValid

The isUrlValid function checks the url address passed in the string for validity.

console.log('Checking URL validity:');
console.log('TRUE /////////////////////////////////////////////////////////////');
console.log(nzfunc.isUrlValid('google.com'), 'google.com');
console.log(nzfunc.isUrlValid('http://google.com'), 'http://google.com');
console.log(nzfunc.isUrlValid('https://google.com'), 'https://google.com');
console.log(nzfunc.isUrlValid('http://www.google.com'), 'http://www.google.com');
console.log(nzfunc.isUrlValid('http://www.google.com/'), 'http://www.google.com/');
console.log(nzfunc.isUrlValid('http://www.google.com:8000'), 'http://www.google.com:8000');
console.log(nzfunc.isUrlValid('http://www.google.com:8000/'), 'http://www.google.com:8000/');
console.log(nzfunc.isUrlValid('http://www.google.com:8000/some'), 'http://www.google.com:8000/some');
console.log(nzfunc.isUrlValid('http://www.google.com:8000/some?'), 'http://www.google.com:8000/some?');
console.log(nzfunc.isUrlValid('http://www.google.com:8000/some?arg'), 'http://www.google.com:8000/some?arg');
console.log(nzfunc.isUrlValid('http://www.google.com:8000/some?a=%bc&b=%ef&c=%H'), 'http://www.google.com:8000/some?a=%bc&b=%ef&c=%H');
console.log('FALSE ////////////////////////////////////////////////////////////');
console.log(nzfunc.isUrlValid('12.34.56.78'), '12.34.56.78');
console.log(nzfunc.isUrlValid('12.34.56.78:8000'), '12.34.56.78:8000');
console.log(nzfunc.isUrlValid('tg://t.me'), 'tg://t.me');

isIPv4withTCPportValid

The isIPv4withTCPportValid function checks the IP address passed in the string for validity.

console.log('Checking IP validity:');
console.log(nzfunc.isIPv4withTCPportValid('12.34.56.78:8000'), '12.34.56.78:8000');
console.log(nzfunc.isIPv4withTCPportValid('12.34.56.78'), '12.34.56.78');

doRequest and getResponse

doRequest and getResponse are asynchronous functions over http.

(async () => {
	let obj = {
		request: 'sendMessage',
		message: 'Hello'
	};
	let options = {
		host: 127.0.0.1,
		port: 8080,
		path: '/',
		method: 'POST',
		headers: {
			'Content-Type': 'application/json',
			'Content-Length': (JSON.stringify(obj)).length
		}
	};
	let req = await nzfunc.doRequest(options, JSON.stringify(obj));
	if (req.statusCode == 200) {
		let res = JSON.parse(await nzfunc.getResponse(req));
		console.log(res);
	}
})();
