- no documentation, not even a few lines - no example without cloning - example provided doesn't run without modifying it (empty video url) - no tests - doesn't look maintained (e.g. 3 years old typescript version) Then looking at index.tsx - using Class as component (debatable but really not idiomatic anymore) - weird empty lines and spaces - weird `this.container` pattern, not to mention the type of it is unsafe - `aspectRatio` has to be in `x:y` format (including the colon), no way to know that unless you read the code in depth (also weird choice) - using the anti-pattern of setting derived state (aspectRatio) in this.state, rendering again with a different aspect ratio won't work - componentWillUnmount does not remove the listener, as calling `.bind` there will create a function that doesn't match the one in componentDidMount - using `.bind` inline insted of using fat arrows directly when creating class methods - the weird syntax for `playerProps =` - hard coding some of the `PlayerVars` props instead of just makin props `PlayerVars & { ... }` to allow passing any props supported by react-youtube Anyway that's just at a glance, I'm sure cloning the project and trying to use it would reveal a lot more.
