Can't set PropTypes correctly in React bouncing between several alternatives












2















In my component I've used the following to set up the props, knowing that it's going to be some kind of data structure (and I was suggested that there's nothing to gain of exact definition of the object's fields).



Compy.propTypes = {
isOpen: PropTypes.bool,
permissions: PropTypes.arrayOf(PropTypes.object),
dismiss: PropTypes.func
};


From that, I got the error as follows.




Warning: Failed prop type: Invalid prop permissions[0] of type string supplied to Compy, expected object.




Based on that, I assumed that the data is a string and that my expectations were wrong (it's an object that is being served but maybe it gets serialized or something, I thought). So I change the type as shown below.



Compy.propTypes = {
isOpen: PropTypes.bool,
permissions: PropTypes.arrayOf(PropTypes.string),
dismiss: PropTypes.func
};


To my surprise, that produced the following error message.





Warning: Failed prop type: Invalid prop permissions[0] of type object supplied to Compy, expected string.





I understand the expected XXX part, since I can see that declaration in the code. What buffles me is that it seems like the complaint changes back, requesting precisely the thing I had previously. What's up with that?



Then I figured that maybe the message complains in regard to the fields inside the object, so I declared a shape according to a blog as shown below. That structure matches precisely what the object looks like (two strings and an array of strings).



Compy.propTypes = {
isOpen: PropTypes.bool,
permissions: PropTypes.arrayOf(PropTypes.shape({
name: PropTypes.string,
code: PropTypes.string,
items: PropTypes.arrayOf(PropTypes.string)
})),
dismiss: PropTypes.func
};



Warning: Failed prop type: Invalid prop permissions[0] of type string supplied to Compy, expected object.




It looks like the computer tries to annoy me by being on the contrary to anything I type. Of course, it's obvious that's not the case. However, being fairly new to React, I can't make sense of it and I'm convinced that, since it's a quite weird behavior, someone will recognize it as something that I can try to debug. At this moment I'm stuck.

          It looks like your permissions array is made up of objects and strings.
          you should be able to avoid the warning by simply declare the fields as of type PropTypes.any



          Compy.propTypes = {
          isOpen: PropTypes.bool,
          permissions: PropTypes.arrayOf(PropTypes.any),
          dismiss: PropTypes.func
          };


          alternatively you can try specifying the allowed types for your array



          Compy.propTypes = {
          isOpen: PropTypes.bool,
          permissions: PropTypes.arrayOf(PropTypes.oneOfType([PropTypes.string, PropTypes.object])),
          dismiss: PropTypes.func
          };


          or make it more flexible and specify in which case it should trigger the warning



          Compy.propTypes = {
          isOpen: PropTypes.bool,
          permissions: PropTypes.arrayOf(function(propValue, key, componentName, location, propFullName) {
          if (!/matchme/.test(propValue[key])) {
          return new Error(
          'Invalid prop `' + propFullName + '` supplied to' +
          ' `' + componentName + '`. Validation failed.'
          );
          }
          }),

          • to understand what is going on you should debug it to check what's the array content at runtime, cause it seems it's made of different types, anyway i've added some alternatives

          • Thank you and yes, I can confirm that PropTypes.any did remove the error message. Now, the permissions array is made up of objects. Period. Each object has three fields - two strings and an array. That array is a bunch of strings. The question is answered as such and I'll check it green in 2 minutes. However, I'd also like to +1 you if you'd suggest a syntax that reflects said structure (instead of shuffling it under the carpet by any). Also, I'd like to bounty anybody who can share some comprehension on why exactly this it's not - it's too kind of weirdness can arise.
