/** | |
* Sets up a DOM MutationObserver that watches for elements using undefined CSS | |
* class names. Performance should be pretty good, but it's probably best to | |
* avoid using this in production. | |
* | |
* Usage: | |
* | |
* import cssCheck from './checkForUndefinedCSSClasses.js' | |
* | |
* // Call before DOM renders (e.g. in <HEAD> or prior to React.render()) |

This script attempts to identify all CSS classes mentioned in HTML but not defined in the stylesheets. | |
In order to use it, just run it in the DevTools console (or add it to DevTools Snippets and run it from there). | |
Note that this script requires browser to support `fetch` and some ES6 features (fat arrow, Promises, Array.from, Set). You can transpile it to ES5 here: https://babeljs.io/repl/ . | |
Known limitations: | |
- it won't be able to take into account some external stylesheets (if CORS isn't set up) | |
- it will produce false negatives for classes that are mentioned in the comments. |
