Package description
The 'isurl' npm package is a utility library designed to provide a simple and efficient way to validate and manipulate URLs in Node.js applications. It offers functions to check if a given string is a valid URL and to parse URLs into their components.
URL Validation
This feature allows developers to check if a string is a valid URL. It returns true if the string is a valid URL and false otherwise. This is useful for validating user input or data fetched from external sources.
const isUrl = require('isurl');
console.log(isUrl('https://www.example.com')); // true
console.log(isUrl('not-a-url')); // falseURL Parsing
This feature provides the ability to parse a URL into its constituent parts, such as protocol, host, path, and query string. This can be particularly useful for applications that need to manipulate or extract information from URLs.
const isUrl = require('isurl');
const url = isUrl.parse('https://www.example.com/path?query=123');
console.log(url.protocol); // 'https:'
console.log(url.host); // 'www.example.com'
console.log(url.pathname); // '/path'
console.log(url.search); // '?query=123'The 'valid-url' package offers similar URL validation capabilities. It provides methods to check if a URL is valid and to normalize URLs. Compared to 'isurl', 'valid-url' focuses more on validation and less on URL parsing.
The 'url-parse' package provides detailed URL parsing capabilities. It offers more extensive options for parsing and manipulating URLs than 'isurl', including the ability to handle relative URLs and extract additional components like username and password from the URL.
