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-caja-sanitizer

An express middleware inspired from express-sanitizer but additionally sanitizes URL params. It also gives an option to provide a preprocessor function to decide whether a (key, value) pair should be sanitized or not.

Build Status

Installation

npm install express-caja-sanitizer

Usage

Needs to be called after express.bodyParser() and before anything that requires the sanitized input, e.g.:

var express = require('express');
var bodyParser = require('body-parser');
var cajaSanitizer = require('express-caja-sanitizer');

var app = express();

app.use(bodyParser());
app.use(cajaSanitizer());

URL Params

This module by default sanitizes the request URL params (req.params), apart from request body and query string params, e.g.:

http://www.myapp.com/rest/user/<script>console.log("hello")</script>bob/details

will be sanitized as

http://www.myapp.com/rest/user/bob/details

Options

shouldSanitize

When shouldSanitize function is provided as an option, the module will sanitize only the (key, value) pairs for which the function returns true.

For example, if we don't want to sanitize XML values then the preprocesser function can be

var shouldSanitize = function(key, value) {
  return !value.startsWith('<?xml version="1.0"')
}

##Limitations This is a basic implementation of Caja-HTML-Sanitizer with the specific purpose of mitigating against persistent XSS risks.

##Caveats This module trusts the dependencies to provide basic persistent XSS risk mitigation. A user of this package should review all packages and make their own decision on security and fitness for purpose.
