Why does `react/require-default-props` still display an error even when a default prop value has been set?

This inquiry pertains to the guideline require-default-props.

Here is the code snippet in question:

function MyComponent({
  blubb = 'my default',
}: {
  blubb?: string,
}) {
  // blubb defaults to 'my default'
};

Eslint is flagging an issue with MyComponent.defaultProps not being properly configured.

I omitted setting it up because the default value is already specified within the function signature (which functions correctly)

Question 1: Why does eslint-plugin-react mandate defaults to be established under defaultProps rather than how I declared it above?

Question 2: Why is this rule enabled by default? Shouldn't optional parameters actually be... optional? What if my default value is simply... undefined? Do I have to explicitly define a default value of undefined when that's already the implicit default?

Your insights are greatly appreciated. <)

Answer №1

To implement a rule in eslintrc.js based on the guidelines provided in the official documentation

Include the code snippet below within the rules section of your configuration file

'react/require-default-props': [2, {
  functions: 'defaultArguments',
}],
