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. TimePicker Component allows the user to specify a time. We can use the following approach in ReactJS to use the ReactJS Blueprint TimePicker Component.

maxTime: It is used to denote the latest time the user can select.
minTime: It is used to denote the earliest time the user can select.
onBlur: It is a callback function that is triggered on blur event emitted by specific time unit input
onChange: It is a callback function that is triggered when the user changes the time.
onFocus: It is a callback function that is triggered on a focus event emitted by a specific time unit input.
onKeyDown: It is a callback function that is triggered on keydown event emitted by specific time unit input.
onKeyUp: It is a callback function that is triggered on keyup event emitted by specific time unit input.
precision: It is used to denote the precision of time the user can set.
selectAllOnFocus: It is used to indicate whether all the text in each input should be selected on focus.

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.

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

App.js

import React from 'react'
import { TimePicker } from '@blueprintjs/datetime'

function App() {

    return (
        <div style={{
            display: 'block', width: 400, padding: 30
        }}>
            <h4>ReactJS Blueprint TimePicker Component</h4>
            <TimePicker />
        </div >
    );
}

export default App;
