react-advanced-loader v2.0.1

React Advanced Loader

React higher-order component that prevents a wrapped component from rendering until specified conditions are met, i.e., an API response is received or some prop is updated. Displays selected animated spinner from better-react-spinkit collection while loading.

Can be used as a higher-order component or as an ES7 class decorator (see examples)

Getting Started

Installing

npm install react-advanced-loader--save-dev

Examples

// Using ES7 Decorators
import React, { PropTypes } from 'react'
import AdvancedLoader from 'react-advanced-loader'

@AdvancedLoader({
  prepare: (props) => props.loadAPIData(),
  isReady: (props) => props.isLoaded
})
export default class MyComponent extends React.Component {
  static propTypes = {
    loadAPIData: PropTypes.func.isRequired,
    isLoaded: PropTypes.bool.isRequired
  }

  render() (
    <div>Component loaded!</div>
  )
}

// ES2015
import React, { PropTypes } from 'react'
import AdvancedLoader from 'react-advanced-loader'

class MyComponent extends React.Component {
  static propTypes = {
    loadAPIData: PropTypes.func.isRequired,
    isLoaded: PropTypes.bool.isRequired
  }

  render() (
    <div>Component loaded!</div>
  )
}

export default AdvancedLoader({
  prepare: (props) => props.loadAPIData(),
  isReady: (props) => props.isLoaded
})(MyComponent) // Enhanced component
