BlueprintJS is a React-based UI toolkit for the web. This library is very optimized and popular for building interfaces that are complex data-dense for desktop applications. TimezonePicker Component provides a way for users to select from a list of timezones. We can use the following approach in ReactJS to use the ReactJS Blueprint TimezonePicker Component.

TimezonePicker Props:

• buttonProps: It is used to denote the props to spread to the target Button.
• className: It is used to denote a space-delimited list of class names to pass along to a child element.
• date: It is used to denote the date to use when formatting timezone offsets.
• disabled: It is used to indicate whether this component is non-interactive.
• inputProps: It is used to denote the props to spread to the filter InputGroup.
• onChange: It is a callback function that is triggered when the user selects a timezone.
• placeholder: It is used to denote the text to show when no timezone has been selected.
• popoverProps: It is used to denote the props to spread to Popover.
• showLocalTimezone: It is used to indicate whether to show the local timezone at the top of the list of initial timezone suggestions.
• value: It is used to denote the currently selected timezone UTC identifier.
• valueDisplayFormat: It is used for the formatting display date and use it when displaying the selected (or default) timezone within the target element.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command:

npx create-react-app foldername

Step 2: After creating your project folder i.e. foldername, move to it using the following command:

cd foldername

Step 3: After creating the ReactJS application, Install the required module using the following command:

npm install @blueprintjs/core
npm install @blueprintjs/popover2

Project Structure: It will look like the following.

Project Structure

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

import React from 'react'
import '@blueprintjs/core/lib/css/blueprint.css';
import { TimezonePicker } from "@blueprintjs/timezone";

function App() {
    return (
        <div style={{
            display: 'block', width: 700, padding: 30
        }}>
            <h4>ReactJS Blueprint TimezonePicker Component</h4>
            <TimezonePicker />
        </div>
    );
}

export default App;

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
