react-modern-loading-spinner

As its name suggests, RMLS is a modern looking loading spinner react component.

P.S. I originally planned to use react-loading-spinner as its name, but as you guessed it, that name was occupied on npm ages ago.

Getting Started

Simply install it

npm install react-modern-loading-spinner

Then use it

import LoadingSpinner from 'react-modern-loading-spinner';

...
render(){
    return (
        ...
        <LoadingSpinner />
    )
}
...

Sensible defaults are picked if nothing is specified, you can get a glimpse of it at the demo, which roughly looks like this (highly recommend you checkout the demo page though):
