react-context-component/src/Context.jsx

This is a React component that lets you add things in the context. Put simply, the [context feature](https://facebook.github.io/react/docs/context.html) basically lets you to pass some data through all nodes in the components tree.

import React, { Component } from 'react'

class ContextProvider extends Component {
  getChildContext () {
    const { children, ...rest } = this.props
    return rest
  }

  render () {
    return this.props.children
  }
}

class Context extends Component {
  constructor (props) {
    super(props)
    const { children, ...rest } = props
    const contextTypes = Object.keys(rest).reduce(
      (acc, current) => {
        acc[current] = () => {}
        return acc
      },
      {}
    )
    ContextProvider.childContextTypes = contextTypes
  }

  render () {
    return <ContextProvider {...this.props} />
  }
}

export default Context
