Errors can be thrown when using React and classNames in the class component

I'm relatively new to React and currently working on a large project. I've run into an issue where I can't use both class and className on all elements and components, particularly custom ones. To work around this, I've had to place the className in a div container, although it doesn't feel like the best practice.

https://i.sstatic.net/GKOHg.png

Coming from Angular and Vue backgrounds, where I could easily apply classes using class or [class], this limitation feels odd. Are there specific scenarios that would prevent me from using class and className on a component or element in the template?

Answer №1

  1. One of the restrictions of JSX is that you cannot use the class keyword on JSX elements.
  2. If you encounter a className error, it could be due to props or types. For example, if you are using className on a div and an error is thrown, it may indicate that a required package is not installed or that you forgot to import the react module when using a version below 17.

Could you provide more details about your setup? Are you using TypeScript with a UI library like MUI? It's important to understand the specific circumstances in which the className error occurs.
