Compose React components with render props

React-composed makes code where you need to get the result of multiple components with render props easier and more readable.

How does it work:

// you might have these two components
const Test1 = ({ children }) => children("Test1");
const Test2 = ({ children }) => children("Test2");

// if you would need both results you would compose them like this:

<Test1>
  {test1 =>
    <Test2>
      {test2 =>
        <p>test1: {test1}, test2: {test2}</p>
      }
    </Test2>
  }
</Test1>

// with react-composed this would look like the following:
import Composed from 'react-composed'

<Composed test1={<Test1/>} test2={<Test2/>}>
  {({test1, test2}) => <p>test1: {test1}, test2: {test2}</p>}
</Composed>

With react-composed you need less nesting. With more API choosing for render-props, instead of HOCs, you'll have more and more components passing information down using render props. For instance react apollo:

<Composed 
  query1={<Query query={query1}} 
  query2={<Query query={query2}} 
  mutation={<Mutation mutation={mutation}}
>
  {({query1, query2, mutation}) => <Component {...} />}
</Composed>

Requirements

react-composed only works with components that adopt the children prop as the primary render prop. Most React components use this convention now (even the official context API uses this)

Installation

Just yarn add react-composed
