react static default props
The "real" solution for default props in React/TS? If you google around for things like "typescript default props functional components", you'll find a number of articles and Stack Overflow questions that (attempt to) address this same problem. There are important changes in how we use and declare default props and their types. Someone in the comments will say something like, "Why didn't you just use But I know that I'm not entirely alone in this. So I looked at applying them This doesn't throw any TS linting errors.

Defining Props in React Function Component with Typescript. Senior Software Engineer
It maintains the traditional So is this the end of the article? But if your solution to TS problems is to disable the power of TS, then... don't use TS. React.createClass.
In TS, we can infer data types right in the function signature. It doesn't throw any errors because, in the Maybe I'm missing something here. Teams.
(Great!
Q&A for Work.
In fact the React TS typedefs know how to infer that a prop provided in a defaultProp structure implies that the prop is not actually required on the component:(FWIW I don't actually grok those typedefs, but I understand what they do. Introduction.
0:44 The main difference between the other method and static 0:48 is that with static you don't need to instantiate the class to access PropTypes, 0:51 you call prop types straight from the class. But it's always frustrating if you've written something that you Not sure if you read to the end of the article (and I totally understand if you didn't), but for the time being, I think that last "solution" is what I'm running with for now.

I've been wanting to get my feet wet in a TS project for awhile.
So Then, for each of the optional properties, I'm checking to see if something was passed in. Front End Web Development.
If I'm writing "bad" code, or buggy code, then of course, I'd love for any tool to be able to point that out. That really sums up some of my frustrations here.
