How to add current time in React js?

Hi Friends 👋,

Welcome To aHoisting!

To add current time in react js, you can set new Date().toLocaleTimeString(). It will add current time in react js.

Today, I am going to show you, how to add current time in react js.

Table of contents

• Install and create a new React app.
• Import react component.
• Create a Component.

Let’s start with the first step.

Step 1: Install and create a new React app.

First you have to install the React project. You should use create-react-app command to create a new React project.

npx create-react-app my-app
cd my-app
npm start

Step 2: Import react component.

After installing, you have to import your React component. To do this, add the following line to the top of your component file.

import React from 'react';

Step 3: Create a Component.

You can set {this.state.currentTime} to add current time in react js.

<div>
  <h3>Welcome to aHoisting</h3>
    <p>Current Time: {this.state.currentTime}</p>
</div>

Define the add current time example.

The below code is an example of a React. You have to import react and set new Date().toLocaleTimeString() to add current time in react js.

App.js

import React from 'react';

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      currentTime: new Date().toLocaleTimeString()
    };
  }

  componentDidMount() {
    this.timerID = setInterval(
      () => this.tick(),
      1000
    );
  }

  componentWillUnmount() {
    clearInterval(this.timerID);
  }

  tick() {
    this.setState({
      currentTime: new Date().toLocaleTimeString()
    });
  }

  render() {
    return (
      <div>
        <h3>Welcome to aHoisting</h3>
        <p>Current Time: {this.state.currentTime}</p>
      </div>
    );
  }
}

export default App;

In the above code example, I have used the Date object and add current time in react js.

Check the output of the above code example.

All the best 👍
