How to Pass Data From One Component to Other Component in React?

Props are used for passing data between the components. We usually use it to pass data from the parent component to the child component.

But what if you need to pass data from Child to Parent component? What if you need to pass data between siblings ??

There can be multiple ways of passing data from one component to another :

1. Using Props

You can use props to pass data from parent to child component. Example 1 illustrates the sample code for this.

|--- App.js
  |---- ParentComponent

2. Using React ContextAPI or State management library like Redux

Redux or React ContextAPI gives you the functionality of central state management to manage your application. It means all the application state will be stored in a single place known as Store.

Like a traditional database represents the point of record for an application, your Store can be thought of as a client-side ‘single source of truth’, or database.

Example #1 — Using Props to pass data from Parent Component to Child Component


import React from 'react'
import ChildComponent from './ChildComponent';

class ParentComponent extends React.Component {
        <ChildComponent message="Data from first component"/>

export default ParentComponent;


import React from 'react';
const ChildComponent = (props) => {
          <h2> {props.message} </h2>
export default ChildComponent;

The above code snippets show how you can pass data from the Parent to Child component.

But, What if we need to pass data from Child to Parent Component ??? Let’s see this in the next!

3. Using Props as Callback Function

If you are not using any state management library like Redux or React ContextAPI and you need to pass data from Child to Parent Component, then callbacks come into the picture.

 |---- Table.js
    |---- ListItem.js

UseCase - When clicking on any rows on the table, Implement functionality to get that row data from the table and display on Table Main page.

Solution - Use Props as callback functions. Let’s see how in the example below!

import React from 'react'
import ListItem from './ListItem';

export class Table extends React.Component {

// Dummy data for the table
state = {
   data: tableData

getData = (rowData) => {
// This is the row data from ChildComponent

              {this.state.data.map(item => (
                   <ListItem rowData={item} handleClick={this.getData}/>

import React from 'react';
const ListItem = (props) => {
    // Using Props handleClick as callback function
          <div onClick={()=> props.handleClick(props.rowData)}>
                <p> {props.rowData.company} </p>
                <p> {props.rowData.contact} </p>
                <p> {props.rowData.country} </p>
export default ListItem;

I hope you now understood how data passing between React Component works. If you find any mistakes, please feel free to correct it by commenting below. I am still learning and documenting what I learn.

I would love to know your thoughts and review on this post.

Editor guide

Precise write up, but for beginners i would recommend a learning curve though, start with passing props, then when you are comfortable with that you can move to using the Context Component, and when you feel boss in that too migrate to the big boys of Redux


Thanks Williams ! I really appreciate it !

You are right as a beginner it's good to first learn the basics then migrate to advanced concepts like Redux or ContextAPI that's why I have not covered these topics in detail.

However, it always better to know what are the possible way to do this.


Hey nice Post

Just a small feedback I think your post would much benefit on syntax highlighting on your code snippets


Hi Alexander,

I didn't know about this feature.

Thank a lot for suggestion. I have done the required changes.


The business logics behind the data passing always confuses me no matter what technology I use
You made some great points! Nice job. Thanks


Thanks David ! I really appreciate it !


I have one question, please advise me on that!

Suppose, ParentComponent.js has some content and ChildComponent.js has some content. And, when i am passing data from parent to child, i don't want to show the ChildComponent.js content inside the ParentComponent.js


Let's understand the hierarchy if I understood your question.

Now, you are saying that I don't want to show content of child in parent. If the strucuture of Child -parent will be this, then the child content will be visible inside parent.


Thanks Anil ! I am glad you liked it!
