Learn how to use the 'mapProps' higher-order component to modify an existing component’s API (its props). 'mapProps' takes incoming props and changes them however you’d like; for example, filtering the props by a field. For example, we have a UserLis…

Learn how to use the ‘withProps’ higher order component to pre-fill a prop, unable to be overridden. const { Component } = React; const { withProps } = Recompose; // with function as arguement const HomeLink = withProps(({ query }) => ({ href: '#/?qu…

Functions created with mapPropsStream canned be composed together to build up powerful streams. Bring in the compose helper from Recompose then simply list your functions in the order you want the props to push through. In the example, we compose thr…

You can decouple the parent stream Component from the mapped React Component by using props.children instead. This process involves mapping the stream to React’s cloneElement with the children then passing the props in manually. We have the code belo…

Rather than using Components to push streams into other Components, mapPropsStream allows you to create functions that can wrap components to create shareable behaviors across components. Using componentFromStream: import React from "react" impo…

Learn how to use the 'withPropsOnChange' higher order component to help ensure that expensive prop computations are only executed when necessary. Simply specify which props are “expensive” and provide a factory function for those props. withPropsOnCh…

mapProps介绍 mapProps函数接收一个函数参数,这个函数参数会返回一个对象用作为接下来的组件的props.组件接收到的props只能是通过mapProps函数参数返回的对象,其他的props将会被忽略 mapProps 实例 const Item = ['a', 'b', 'c', 'd']; const ListMap = mapProps(({ list }) => { return { list: list.map((e) => e + '_extends') }; })(L…

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…

If you hard-code a stream of props to target a specific prop, it becomes impossible to reuse that stream with any other components. Configuring your props stream with lenses will allow you to reuse your stream with any React component. Checkout: lens…
