required field is always false

[davidfirst]

I get "required": false also when I set my variable to be required, e.g. PropTypes.number.isRequired.

An example code

MyComponent.propTypes = {
  foo: PropTypes.number.isRequired,
};

I get

{
  "description": "General component description.",
  "displayName": "MyComponent",
  "methods": [],
  "props": {
    "foo": {
      "type": {
        "name": "number"
      },
      "required": false,
      "description": "",
      "defaultValue": {
        "value": "42",
        "computed": false
      }
    }
  }
}

Which version of react-docgen are you using?

[davidfirst]

The latest. 3.0.0.
The code I used is from the readme. (which by the way threw an error, until I replaced render: function() { with render: () => { ).

Thanks for reporting I was able to reproduce this.

After inspecting, there is not really a problem. The confusion with the example comes because foo in that example has a default value. Props with a default value are never required even if isRequired is set. The problem is more, that the definition of the component is wrong. One should not use isRequired and then define a defaultValue.

I will fix the example.
