What is regexparam?

The regexparam npm package is a utility for matching URL patterns using regular expressions. It is designed to be lightweight and efficient, making it suitable for routing in web applications.

What are regexparam's main functionalities?

Basic Pattern Matching

This feature allows you to define URL patterns with named parameters. The `parse` function converts the pattern into a regular expression and extracts parameter names.

const { parse } = require('regexparam');
const result = parse('/user/:id');
console.log(result);

Matching URLs

This feature allows you to match a URL against a predefined pattern. The `match` function returns an object with the matched parameters if the URL matches the pattern.

const { match } = require('regexparam');
const pattern = parse('/user/:id');
const result = match('/user/123', pattern);
console.log(result);

Optional Parameters

This feature allows you to define optional parameters in your URL patterns. The `parse` function can handle patterns with optional parameters, and the `match` function will correctly match URLs with or without the optional parameter.

const { parse, match } = require('regexparam');
const pattern = parse('/user/:id?');
const result1 = match('/user/123', pattern);
const result2 = match('/user', pattern);
console.log(result1, result2);
