React.js Blueprint Date Input Date Formatting

Blueprint is a React-based UI toolkit for the web. This library is very optimized and popular for building interfaces that are complex and data-dense for desktop applications.

In this article, we’ll discuss React.js Blueprint Date Input Date formatting. The Date Input component is a type of InputGroup that allows the users to pick the date as per choice and also the time zones. It shows a DatePicker inside a Popover when focused. In the blueprint, we can also format the date using two props: formatDate() and parseDate().

Syntax:

<DateInput
    value={...}
      formatDate={...}
      parseDate={...}
/>

Creating React Application And Installing Module:

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

npm create-react-app appname

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

cd appname

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

npm install @blueprintjs/core

Step 4: Installing @blueprintjs datetime component.

npm install @blueprintjs/datetime

Project Structure:

Steps to run the application: Run the project as follows:

npm start

Example 1: The below example demonstrates the usage of the formatDate prop of the DateInput component. The formatDate prop receives the current date and returns a locale string representation of it. It cannot have the user input the Date in the form of text input.

Javascript

import React, { useCallback, useState } from "react";
import "@blueprintjs/core/lib/css/blueprint.css";
import "@blueprintjs/datetime/lib/css/blueprint-datetime.css";
import { DateInput } from "@blueprintjs/datetime";

function App() {
    const [dateVal, setDateVal] = useState(null);
    const handleChange = useCallback(setDateVal, []);
    const formatDate = useCallback((Date) =>
        Date.toLocaleString(), []);

    return (
        <center>
            <div style={{ textAlign: "center", color: "green" }}>
                <h1>GeeksforGeeks</h1>
                <h2>ReactJs Blueprint DateInput Date Formatting</h2>
            </div>
            <div style={{ width: 500 }}>
                <DateInput
                    formatDate={formatDate}
                    onChange={handleChange}
                    placeholder="mm/dd/yyyy"
                    value={dateVal}
                />
            </div>
        </center>
    );
}

export default App;

Output:

Example 2: The below example demonstrates the usage of the parseDate prop of the DateInput component. The parseDate prop receives text inputted by the user which is then converted to a Date object and becomes the next value of the DateInput component.

Javascript

import React, { useCallback, useState } from "react";
import "@blueprintjs/core/lib/css/blueprint.css";
import "@blueprintjs/datetime/lib/css/blueprint-datetime.css";
import { DateInput } from "@blueprintjs/datetime";

function App() {
    const [dateVal, setDateVal] = useState(null);
    const handleChange = useCallback(setDateVal, []);
    const formatDate = useCallback((Date) =>
        Date.toLocaleString(), []);
    const parseDate = useCallback((string) =>
        new Date(string), []);

    return (
        <center>
            <div style={{ textAlign: "center", color: "green" }}>
                <h1>GeeksforGeeks</h1>
                <h2>ReactJs Blueprint DateInput Date Formatting</h2>
            </div>
            <div style={{ width: 500 }}>
                <DateInput
                    formatDate={formatDate}
                    parseDate={parseDate}
                    onChange={handleChange}
                    placeholder="mm/dd/yyyy"
                    value={dateVal}
                />
            </div>
        </center>
    );
}

export default App;
