findDOMNode usage: https://github.com/researchgate/react-intersection-observer/blob/83e69e271d9a21577d1749bc938d776677be144e/src/IntersectionObserver.js#L105

This is now deprecated: https://reactjs.org/docs/strict-mode.html#warning-about-deprecated-finddomnode-usage.

This means users of this library will not be able to use concurrent mode, as it does not support findDOMNode: https://reac

If I'm not mistaken the blur and black and white effects are related to the placeholderSrc, and opacity creates a blank space then transition to the loaded image.

It would be nice if I define placeholder prop, then the opacity effect could use it

Ex:
<LazyLoadImage src="some-big-image.jpg" placeholder={<div>Loading...</div>} effect="opacity" />

I got weird typing errors after adding react-lazy-images to my project and didn't understand them until I read #13. Using the workaround described there works for me. I think, however, it would make this project easier to use for anyone using TypeScript if this requirement were clearly documented in the project's README. Otherwise you have to have the insight to look into the closed GitHub issues

Hi,

first, let me thank you for this modern alternative to react-reveal! Was mostly a plug- & play-replacement process.

However, one feature I'd like to see is missing: the when prop.

Example use case:

• login form shakes on error: <Shake when={!!error}>{children}</Shake>
