DOMPurify is a DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, MathML and SVG. It's written in JavaScript and works in all modern browsers (Safari, Opera (15+), Internet Explorer (10+), Firefox and Chrome - as well as almost anything else using Blink or WebKit). DOMPurify is written by security people who have vast background in web attacks and XSS. Fear not.
The eslint-plugin package is an ESLint plugin that contains a collection of recommended ESLint rule configurations which you can extend from in your own ESLint configs, as well as an Nx-specific lint rule called enforce-module-boundaries.
The Workspace plugin contains executors and generators that are useful for any Nx workspace. It should be present in every Nx workspace and other plugins build on it.
