Utility method for warning when elements have a `class` attribute that refers to an undefined CSS class

Package Exports

  • checkcss

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (checkcss) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

csscheck

Utility method for warning any time the class attribute of an element references undefined / non-existent CSS class.

In addition to doing a sweep of the DOM at the time cssCheck() is called, this sets up a MutationObserver to continuously monitor DOM changes, so is well-suited for dynamic webapps.

(Note: The monitoring logic is pretty efficient but is probably not something you want to be running in production.)

Installation

npm i csscheck

Usage

import cssCheck, { cssMonitor } from 'csscheck';

// Check current DOM
cssCheck();

// ... and setup monitor to check DOM as it changes
cssMonitor();
