In angular, I could apply two directives on one element.

<div dir-one dir-two></div>

What would be the equivalent in react?

You can do it like this

var FirstComponent = React.createClass({
    render: function() {
        return <div>FirstComponent</div>;
    }
});

var SecondComponent = React.createClass({
    render: function() {
        return <div>SecondComponent</div>;
    }
});

var MainComponent = React.createClass({
    render: function() {
        return <div>
            <FirstComponent />
            <SecondComponent />
        </div>;
    }
});

How do I merge two components in react, that don't have a parent-child relationship, you can set up your own global event system. Subscribe to events in componentDidMount(), unsubscribe in componentWillUnmount(), and call setState() when you receive an event. In React, an owner is the component that sets the props of other components. More formally, if a component X is created in component Y 's render() method, it is said that X is owned by Y . As discussed earlier, a component cannot mutate its props — they are always consistent with what its owner sets them to.

maybe you can use fragemts, https://reactjs.org/docs/fragments.html

`render() {
  return (
    <React.Fragment>
      <ChildA />
      <ChildB />
      <ChildC />
    </React.Fragment>
  );
}`

You can try the component to be rendered by another component something like this:

render() {
    return (
        <div>
           <h1>I am your father</h1>
           <Child />
        </div>
    );
}

Is it OK to use React.render() multiple times in the DOM?, But as your React JS app becomes more and more complex, there is a need to create components as different JavaScript files which helps our  React is all about re-using code, and it can be smart to insert some of your components in separate files. To do that, create a new file with a.js file extension and put the code inside it: Note that the file must start by importing React (as before), and it has to end with the statement export default Car;.

Fragments – React, example-component.jsx. import React from 'react'. import joinChildren from 'react-​join-children'. import { Item, Separator } from 'justanexample'. export default  Components can refer to other components in their output. This lets us use the same component abstraction for any level of detail. A button, a form, a dialog, a screen: in React apps, all those are commonly expressed as components. For example, we can create an App component that renders Welcome many times:

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.

Ever wanted to join react children like you join an array? · GitHub, how can you embed two or more components into one in react react multiple root components how to return multiple components in react react compose  setState() enqueues changes to the component state and tells React that this component and its children need to be re-rendered with the updated state. This is the primary method you use to update the user interface in response to event handlers and server responses.

  • There's no direct equivalent. It depends on what you're trying to do.
  • You should also take a look at stateless funcional components for this kind of things :)
