url-parse-lax

What is url-parse-lax?

The url-parse-lax package is designed to simplify the parsing of URLs with a more lenient approach to validation, making it easier to work with a wide range of URLs that might not strictly adhere to the standard formats. It builds upon the native URL parsing capabilities of Node.js, providing a more forgiving parsing process that can be particularly useful when dealing with user-generated or imperfect URLs.

What are url-parse-lax's main functionalities?

Parsing URLs with leniency

This feature allows for the parsing of URLs without requiring a protocol. It automatically prepends 'http://' to URLs that omit the protocol, making it easier to work with URLs provided in various formats.

const urlParseLax = require('url-parse-lax');
const parsedUrl = urlParseLax('www.example.com');
console.log(parsedUrl);

Extracting URL components

Beyond just lenient parsing, url-parse-lax also allows for easy extraction of different components of the URL, such as the pathname, search query, and hash fragment. This can be particularly useful for routing or processing specific parts of a URL.

const urlParseLax = require('url-parse-lax');
const parsedUrl = urlParseLax('http://www.example.com/path?query=123#fragment');
console.log(parsedUrl.pathname);
console.log(parsedUrl.search);
console.log(parsedUrl.hash);
