Learn how to use the ‘branch’ and ‘renderNothing’ higher-ordercomponents to render nothing when a certain prop condition ismet. Sometimes you only want to render a component when validprops exist or are in a certain condition; ‘renderNothing’ isan ea…

This lesson takes the concept of render props and migrates it over to streaming props by keeping the same example and simple refactoring the Togglecomponent which handles the render prop. const ToggleStream = componentFromStream(props$ => { const { h…

Learn how to user the ‘componentFromProp’ helper and ‘defaultProps’ higher order component to swap the underlying html tag of your component. Sometimes we want a component to behave the same overall but to use a different element in the HTML output.…

Learn how to use the 'lifecycle' higher-order component to conveniently use hooks without using a class component. import React from 'react'; import { withReducer, withHandlers, compose, lifecycle } from 'recompose'; // Mock Configuration function fe…

We often want to render a Route conditionally within our application. In React Router v4, the Route components match the current route inclusively so a “stack” of Routes will all be processed. To render a single Route exclusively we can wrap them in…

Learn how to use the 'withState' and 'withHandlers' higher order components to easily add local state to—and create a reusable local state pattern for—your functional stateless components. No need for classes! withState: const Statue = withState('sho…

There are many cases where we will need a catch-all route in our web applications. This can include 404-style routes when nothing is match or other use cases where where we receive an invalid route in React Router v4. We can use 'Switch' from 'react-…

Events are the beginning of most every stream. Recompose provides a createEventHandler function to help your create handler and stream pairs. Once the handler/stream pairs are created, it’s simply a matter of passing the handlers down the stream as p…

Recompose provides helper functions to stream props using an Observable library of your choice into React. This lesson shows you how to configure Recompose to use RxJS then create a Streaming Component with Recompose’s componentFromStream helper func…

前言 最近在学习React的封装,虽然日常的开发中也有用到HOC或者Render Props,但从继承到组合,静态构建到动态渲染,都是似懂非懂,索性花时间系统性的整理,如有错误,请轻喷~~ 例子 以下是React官方的一个例子,我会采用不同的封装方法来尝试代码复用,例子地址. 组件在 React 是主要的代码复用单元,但如何共享状态或一个组件的行为封装到其他需要相同状态的组件中并不是很明了. 例如,下面的组件在 web 应用追踪鼠标位置: class MouseTracker extends R…
