Component has Render Method, but does Not Extend React.Component

QUESTION

Component has Render Method, but does Not Extend React.Component

Asked 2019-Sep-19 at 23:08

Component appears to have a render method, but doesn't extend React.Component. This is likely to cause errors. Change to extend React.Component instead

Using the extends-classes library causes a react component to fail rendering with the above error. I'd like to compose a class featuring the React.Component methods and some other methods contained in a different class so I can split my code more concisely.

Example:

I wouldn't have expected this to work to begin with. Let's examine how this extends-classes library works.

The classes function returns a dummy class that within its constructor goes through all classes listed as arguments to the classes function and copies over all functions and properties to the aforementioned dummy class. It then calls the constructor of all classes.

tl;dr: it mashes everything together so the class you're actually extending from is not an actual instance of React.Component. Which is most likely why you're getting this error.

Don't fight the language. The language doesn't support multi inheritance. May I suggest you use composition over inheritance instead?
