Error: Missing converter for X

[danieldelcore]

This is a common issue with extract-react-types (ERT), which essentially means that:

You are using a language feature that ERT is not familiar with

The way ERT evaluates complex types and language specific features is largely a manual process. We have to manually tell ERT how to interpret things like extends and React.FC, so inevitably there will be things that we don't support or haven't considered.

For a list of all supported and unsupported features, see this issue: https://github.com/atlassian/extract-react-types/issues/149

For example purposes, consider the scenario that the unknown keyword is not known to ERT. When the code below is parsed, it will error stating: Missing converter for: TSUnknownKeyword

interface FooProps {
  // Docs about the bar property here
  bar: unknown; 
}

const Foo = props => null;
