parseurl 1.3.3

Parseurl is a powerful Node.js module extensively used to parse URLs with memoization. It's essentially designed to enhance performance and efficiency in Node.js applications through caching. When the same request object is used and the URL doesn't change, parseurl will return a cached parsed object rather than parsing the URL again, ensuring rapid response times. It is a nifty utility and an excellent tool that is easy to integrate and use in your Javascript projects.

The use of parseurl is straightforward. The first step is to install it using the npm package manager. Run npm install parseurl in your terminal to add it to your project. After successful installation, you can require it in your relevant JavaScript file by adding var parseurl = require('parseurl').

Parseurl provides two main functions.

1. parseurl(req): This function parses the URL of the given request object, looking at the req.url property. It returns the result, which is the same as url.parse in Node.js core.

Example:

var parseurl = require('parseurl')
var http = require('http')

http.createServer(function (req, res) {
  var url = parseurl(req)
  console.log(url)
  // Do something with url
}).listen(3000)

2. parseurl.original(req): This function parses the original URL of the given request object and return the result. It first tries to parse req.originalUrl if it is a string, otherwise it parses req.url.

Example:

var parseurl = require('parseurl')
var http = require('http')

http.createServer(function (req, res) {
  var originalUrl = parseurl.original(req)
  console.log(originalUrl)
  // Do something with originalUrl
}).listen(3000)

Remember, calling these functions multiple times with the same request where the URL doesn't change will fetch the cached parsed object, enhancing the performance of your Node.js application.

The documentation for parseurl can be found directly in its README file on the GitHub repository at https://github.com/pillarjs/parseurl. The README provides a comprehensive guide on installing the module, details of the API, and examples of usage. It's a great resource for anyone interested in gaining a solid understanding of the parseurl module. Keep the URL bookmarked for quick navigation when needed.
