react-kurtsore

This library is a collection of mixins for managing component state with kurtsore cursors.

Installation

$ npm install react-kurtsore

Usage

CursorPropsMixin

The CursorPropsMixin mixin implements an efficient shouldComponentUpdate for react components that receive cursors in their props. It is similar to react.addons.PureRenderMixin in that it assumes that the same non-cursor props and state shouldn't trigger a re-render.

Apart from state and non-cursor prop checks, it will return true iff the snapshots of the cursor props are different. You just need to add it as a mixin in your components that receive cursors as props:

var k = require("kurtsore"),
    React = require("react"),
    rk = require("react-kurtsore");

var Hello = React.createClass({
    propTypes: {
        user: React.PropTypes.instanceOf(k.Cursor)
    },

    mixins: [ rk.CursorPropsMixin ],

    render: {
        var user = this.props.user.deref();
        return <h1>Hello, {user}</h1>
    }
});
