How to pass in a react component into another react component to transclude the first component's content?

how to pass value from one component to another component in reactjs
react pass component as prop typescript
react pass component class as prop
react pass object to component
react pass component type as prop
react pass component as prop and add props
react pass state as props to child components
react pass component as argument

Is there a way to pass one component into another react component? I want to create a model react component and pass in another react component in order to transclude that content.

Edit: Here is a reactJS codepen illustrating what I'm trying to do. http://codepen.io/aallbrig/pen/bEhjo

HTML

<div id="my-component">
    <p>Hi!</p>
</div>

ReactJS

/**@jsx React.DOM*/

var BasicTransclusion = React.createClass({
  render: function() {
    // Below 'Added title' should be the child content of <p>Hi!</p>
    return (
      <div>
        <p> Added title </p>
        {this.props.children}
      </div>
    )
  }
});

React.renderComponent(BasicTransclusion(), document.getElementById('my-component'));

You can use this.props.children to render whatever children the component contains:

const Wrap = ({ children }) => <div>{children}</div>

export default () => <Wrap><h1>Hello word</h1></Wrap>

Pass react component as props, Using this.props.children is the idiomatic way to pass instantiated components to a react component const Label = props => <span>{props.children}</span>� When you pass a component as a parameter directly, you pass it uninstantiated and instantiate it by retrieving it from the props. This is an idiomatic way of passing down component classes which will then be instantiated by the components down the tree (e.g. if a component uses custom styles on a tag, but it wants to let the consumer choose


Note I provided a more in-depth answer here

Runtime wrapper:

It's the most idiomatic way.

const Wrapper = ({children}) => (
  <div>
    <div>header</div>
    <div>{children}</div>
    <div>footer</div>
  </div>
);

const App = () => <div>Hello</div>;

const WrappedApp = () => (
  <Wrapper>
    <App/>
  </Wrapper>
);

Note that children is a "special prop" in React, and the example above is syntactic sugar and is (almost) equivalent to <Wrapper children={<App/>}/>


Initialization wrapper / HOC

You can use an Higher Order Component (HOC). They have been added to the official doc recently.

// Signature may look fancy but it's just 
// a function that takes a component and returns a new component
const wrapHOC = (WrappedComponent) => (props) => (
  <div>
    <div>header</div>
    <div><WrappedComponent {...props}/></div>
    <div>footer</div>
  </div>
)

const App = () => <div>Hello</div>;

const WrappedApp = wrapHOC(App);

This can lead to (little) better performances because the wrapper component can short-circuit the rendering one step ahead with shouldComponentUpdate, while in the case of a runtime wrapper, the children prop is likely to always be a different ReactElement and cause re-renders even if your components extend PureComponent.

Notice that connect of Redux used to be a runtime wrapper but was changed to an HOC because it permits to avoid useless re-renders if you use the pure option (which is true by default)

You should never call an HOC during the render phase because creating React components can be expensive. You should rather call these wrappers at initialization.


Note that when using functional components like above, the HOC version do not provide any useful optimisation because stateless functional components do not implement shouldComponentUpdate

Facebook recommends stateless component usage Source: https://facebook.github.io/react/docs/reusable-components.html

In an ideal world, most of your components would be stateless functions because in the future we’ll also be able to make performance optimizations specific to these components by avoiding unnecessary checks and memory allocations. This is the recommended pattern, when possible.

function Label(props){
    return <span>{props.label}</span>;
}

function Hello(props){
    return <div>{props.label}{props.name}</div>;
}

var hello = Hello({name:"Joe", label:Label({label:"I am "})});

ReactDOM.render(hello,mountNode);

Render Props – React, A component with a render prop takes a function that returns a React element and Now the question is: How can we reuse this behavior in another component? As a first pass, you might try rendering the <Cat> inside <Mouse> ' s render� With React, typically you only need to bind the methods you pass to other components. For example, <button onClick={this.handleClick}> passes this.handleClick so you want to bind it. However, it is unnecessary to bind the render method or the lifecycle methods: we don’t pass them to other components.


Components and Props – React, Components let you split the UI into independent, reusable pieces, and think This function is a valid React component because it accepts a single “props” Extracting components might seem like grunt work at first, but having a palette of JSX, and Build Steps � Passing Functions to Components � Component State� React per se doesn't provide a way to share data between components unless they're in the same component hierarchy. Only ancestor-to-descendent passing is provided by React directly, by passing data from parent components to child components via "props".
