react-loader 

react-loader provides your React.js
component a simple mechanism for rendering a loading spinner (via
spin.js) while data is loading, such as an
asynchronous request to load data for a view.

> Important Note: The 2.x tagged release is compatible with React 1.4 and higher. If
> you're working with an older version of React, please use the 1.x release.

Installation

react-loader is available through both Bower and
npm via:

npm install react-loader

or:

bower install react-loader

Be sure to include the --save option to add this as a dependency in your
application's package.json or bower.json file.

Usage

Wrap the Loader component around your loading content within your React
component's render function.

``jsx
/* @jsx React.DOM /
var Loader = require('react-loader');

var MyComponent = React.createClass({
getInitialState: function () {
return { loaded: false, profile: null };
},

componentDidMount: function () {
new Profile({ id: this.props.id }).fetch({
success: this.onSuccess,
error: this.onError
})
},

onSuccess: function (profile) {
this.setState({ profile: profile, loaded: true });
},

onError: function (err) {
// error handling goes here
},

render: function () {
return (



My Profile






);
}
});
`

Options can be passed to the Loader component as properties. The Loader accepts
a loaded boolean that specified whether the spinner or content should be
displayed, defaulting to false. It also accepts a component property to
specify the DOM node, defaulting to "div". Additionally, all options
available to spin.js are available to this component in two ways.

1. First, you can pass each option onto the loader as individual properties:

`jsx
corners={1} rotate={0} direction={1} color="#000" speed={1}
trail={60} shadow={false} hwaccel={false} className="spinner"
zIndex={2e9} top="50%" left="50%" scale={1.00}
loadedClassName="loadedContent" />
`

2. Alternatively, you can use supply an object using the options key:

`jsx
var options = {
lines: 13,
length: 20,
width: 10,
radius: 30,
scale: 1.00,
corners: 1,
color: '#000',
opacity: 0.25,
rotate: 0,
direction: 1,
speed: 1,
trail: 60,
fps: 20,
zIndex: 2e9,
top: '50%',
left: '50%',
shadow: false,
hwaccel: false,
position: 'absolute'
};


`

The loader is rendered inside a DIV element (unless otherwise specified via the
component property mentioned earlier) with class "loader". A simple solution
for rendering the spinner on the center of your screen would be to use some CSS
like the following:

`css
.loader {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: white;
z-index: 9999;
}
`

Once the content is loaded and the spinner is removed, the DOM node is given a
class of "loadedContent" (which is customizable by specifying the
loadedClassName property).
