Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Express IP Whitelist

An express middleware for access permissions based on Host/IP addresses. Hosts/IPs of the clients that are not on the whitelist have access blocked.

Features

  • Create a list of permissions with hostnames and IP addresses and control who can access the resources of your API;
  • Support IPv4, IPv6, CIDR format & IPv4 mapped IPv6 addresses;
  • Custom log function;
  • Custom message function.

Installation

npm i @nutes-uepb/express-ip-whitelist


Usage

To use middleware is very simple, just import and then define your list of permissions and available options, such as log and message.

const whitelist = require('@nutes-uepb/express-ip-whitelist');

// Create middleware.
const middleware = whitelist(['127.0.0.1', 'www.client.com'], options);

// Injecting middleware into instance express
const express = require('express');
const app = express();
app.use(middleware);

Options

const options = {  
  log: (clientIp, accessDenied) => {
      console.log(`${clientIp} access ${accessDenied ? 'denied!' : 'allowed!'}`)  
 }, message: function (err, clientIp) {  
	  return {error: `Client with IP address ${clientIp} is not allowed!`}  
 }};

The options are not mandatory and have default values.

  • log: Allows you to manipulate the log on each request. To disable log assign its value equal to false.
    • Valor default:
      function (clientIp, accessDenied) {	
          console.log(`Access ${accessDenied ? 'denied' : 'allowed'} for ip address ${clientIp}`)  
      }
  • message: Allows you to handle the error message when the client IP is not on the whitelist. The status code will always be 401.
    • Valor default:
      function (err, clientIp) {  
          return {  
              code: '401',  
              message: 'Unauthorized',  
              description: `Access denied for IP address ${clientIp}`  
          }  
      }
