I am new to React and trying to pass object through attributes but getting following error.

Uncaught Invariant Violation: Objects are not valid as a React child (found: object with keys {title}). If you meant to render a collection of children, use an array instead or wrap the object using createFragment(object) from the React add-ons. Check the render method of MeetingComponent.

Here is my code:

Main.jsx

import React from 'react';
import MeetingComponent from '../components/Meeting.jsx';

let meeting = {
  title: 'Some title'
};

class AppComponent extends React.Component {
    render() {
        return (
            <div className="index">
                <MeetingComponent dataMeeting={meeting} />
            </div>
    );
  }
}

AppComponent.defaultProps = {};

export default AppComponent;

Meeting.jsx

import React from 'react';

class MeetingComponent extends React.Component {
    render() {
        return (
            <div>{this.props.dataMeeting}</div>
        );
    }
}

MeetingComponent.defaultProps = {};

export default MeetingComponent;

How can I solve this? What is the best practice?

The problem is here

 <div>{this.props.dataMeeting}</div>

You cannot render an object in React, maybe you were trying to do

 <div>{this.props.dataMeeting.title}</div>

React - passing object through props, In this guide, we'll go through the React props in detail. We'll also look at how we can pass a props object from a child component to a parent  React Props vs. State. Passing only props from component to component doesn't make the component interactive, because nothing is there to change the props. Props are read-only. That's the time when React State comes into play which can be changed. The state is co-located to a React component.

i've used this method to pass object through component

   let meeting = {
  title: 'Some title'
};

class AppComponent extends React.Component {
    render() {
const jsonData =JSON.stringify(meeting);
        return (
            <div className="index">
                <MeetingComponent dataMeeting={jsonData } />
            </div>
    );
  }
}


class MeetingComponent extends React.Component {
    render() {
const data = JSON.parse(this.props.dataMeeting);
        return (
            <div>{data}</div>
            <div>{data.title}</div>
        );
    }
}

How to Pass Props Object from Child Component to Parent , The vehicle we use to pass state between components is a Javascript object named props . We already said that functional components are just  React is pretty flexible but it has a single strict rule: All React components must act like pure functions with respect to their props. Of course, application UIs are dynamic and change over time. In the next section, we will introduce a new concept of “state”. State allows React components to change their output over time in response to user actions, network responses, and anything else, without violating this rule.

  static propTypes = {
    pieChartSortSettings: PropTypes.shape({
      type: PropTypes.string.isRequired,
      order: PropTypes.string.isRequired,
    }),
  };

Here is a example how to pass object in props. You can also checkout methods like: PropTypes.arrayOfand PropTypes.objectOf(more: https://reactjs.org/docs/typechecking-with-proptypes.html)

Passing state through the props object in React - DEV, As you learn how to develop web applications using React, you will will just be passed into a component as regular props object properties,  While it may sound confusing, props are nothing but objects which are used to pass data from one component to another. In this guide, we'll go through the React props in detail. We'll also look at how we can pass a props object from a child component to a parent component.

If you want to pass properties of an object , it can be done as follows:

<MeetingComponent {...meeting} />

To access title of the meeting object inside the Meeting component, you can do it by calling it directly this.props.title

You can render it as <div>{this.props.title}</div>

The beginner's guide to mastering React props, But props can be anything from integers over objects to arrays. Basically, that's how props are passed to React components. As you may have Historically the best approach to it was using JavaScript's logical OR operator. The React.Children.toArray() function does exactly what you’d imagine it does. You pass it a children prop, and it’ll return an array. If children only contains one child, it’ll wrap that child in an array, which you can then slice() and concat() like a ninja.

Best practice is make your props as plain as possible, in your case it may be

<MeetingComponent title={ meeting.title } />

class MeetingComponent extends React.Component {
propTypes = {
   title: React.PropTypes.string.isRequired
}
render() {
    return (
        <div>title: { this.props.title }</div>
    );
  }
}

And always use propTypes for better warning messages

Props!, React.createElement(Component, Object.assign({}, this.props, { more: 'values' }));​. The rest of Most of the time you should explicitly pass the properties down. Pass event handlers and other functions as props to child components: < button onClick = { this . handleClick } > If you need to have access to the parent component in the handler, you also need to bind the function to the component instance (see below).

Transferring Props, Then wrap your component with a div that uses this key as a prop. // var details = this.props.cDetails; return ( {this.props.cDetails.map(function(detail,  Pass params to a route by putting them in an object as a second parameter to the navigation.navigate function: navigation.navigate('RouteName', { /* params go here */ }) Read the params in your screen component: route.params. We recommend that the params you pass are JSON-serializable.
