How to create calendar in ReactJS with bootstrap

Getting Started

Creating a calendar in ReactJS with Bootstrap is like building a Lego house: you start with smaller blocks(components) and join them together to create a larger structure(the calendar). In this blog, we will walk you through this process step by step, so you can easily create an interactive calendar component in ReactJS using Bootstrap for styling.

Setting Up Your Environment

Before we start building our Lego house, we need to ensure we have all the necessary blocks at our disposal. In our case, these blocks are the ReactJS and Bootstrap libraries. Here's how you can set up your environment:

npx create-react-app calendar-app
cd calendar-app
npm install react-bootstrap bootstrap

The first command creates a new ReactJS application, and the second command navigates into the app's directory. The last command installs Bootstrap in your app.

Creating the Calendar Component

Now, let's start building our calendar. First, we need a place(calendar component) to store all the days of the month. Let's create a new file Calendar.js in the src directory and add the following code:

import React from 'react';
import { Container } from 'react-bootstrap';

const Calendar = () => {
  return (
    <Container>
      {/* Calendar will go here */}
    </Container>
  );
};

export default Calendar;

Here, we've created a functional component using an arrow function (a shorter way to write functions). We're using the Container component from Bootstrap to center our calendar on the page.

Adding Days to the Calendar

A calendar is like a chocolate box; it's divided into smaller sections, each representing a day. We'll use the Row and Col components from Bootstrap to create these sections.

Let's create a new file Day.js in the src directory to represent a day:

import React from 'react';
import { Col } from 'react-bootstrap';

const Day = () => {
  return (
    <Col>
      {/* Day will go here */}
    </Col>
  );
};

export default Day;

Next, let's import the Day component in our Calendar component and display a week:

import React from 'react';
import { Container, Row } from 'react-bootstrap';
import Day from './Day';

const Calendar = () => {
  const week = [1, 2, 3, 4, 5, 6, 7];

  return (
    <Container>
      <Row>
        {week.map(day => <Day key={day} />)}
      </Row>
    </Container>
  );
};

export default Calendar;

Here, we're mapping over the week array and for each day, we're rendering a Day component. The key prop is a unique identifier that React uses for performance reasons.

Displaying the Date

Now, our chocolate box(calendar) needs chocolates(days with dates). Let's add the date to our Day component:

import React from 'react';
import { Col } from 'react-bootstrap';

const Day = ({ date }) => {
  return (
    <Col>
      {date}
    </Col>
  );
};

export default Day;

And pass the day as a date prop to the Day component in our Calendar component:

import React from 'react';
import { Container, Row } from 'react-bootstrap';
import Day from './Day';

const Calendar = () => {
  const week = [1, 2, 3, 4, 5, 6, 7];

  return (
    <Container>
      <Row>
        {week.map(day => <Day key={day} date={day} />)}
      </Row>
    </Container>
  );
};

export default Calendar;

Just like that, we've filled our chocolate box(calendar) with chocolates(days with dates).

Adding Navigation

Now, our Lego house (calendar) needs doors (navigation). To create navigation, we'll use the Button component from Bootstrap. Let's import it in our Calendar component:

import { Container, Row, Button } from 'react-bootstrap';

And add two buttons for previous and next month navigation:

<Container>
  <Row>
    <Button>Previous</Button>
    <Button>Next</Button>
  </Row>
  {/* Rest of the code */}
</Container>

With this, our Lego house (calendar) is now complete with doors (navigation buttons).

Conclusion

Just like building a Lego house, creating a calendar in ReactJS with Bootstrap can be broken down into smaller, manageable tasks. By focusing on one part at a time - setting up the environment, creating the calendar component, adding days, displaying the date, and adding navigation - we can gradually construct our calendar, piece by piece. Remember, every complex component is just a collection of simpler ones. So, keep practicing, keep building, and soon, you'll be able to construct not just a Lego house, but an entire Lego city! Happy coding!
