react-component-jumbotron-01

Demonstrates the Jumbotron feature used on my site (www.millder.com.au).

Purpose

This is a React component built with scalability in mind.

The Jumbotron in this repository is created as a container with components which make up this specific layout.

The explanation and details provided below are based on the references provided in this repository and hopefully can be used for referencing and education purposes.

npm Packages Used

• styled-components

In a Nutshell

The App.js references the container/component JumbotronContainer.js located in the src/container folder.

The container loops through the information listed in the object of jumbotronData.json file located in the src/data folder, which then will be displayed in the Jumbotron.

Let’s Dive In

Compound Component

The first thing to note is the use of the compound component to create the components that make up this specific layout.

In the src/components folder, a component folder named Jumbotron is created. In this folder, the following are added:

• an index.js file, and
• a styles folder, which itself include the JumbotronStyles.js file.

JumbotronStyles.js

This file lists all the styled components, with the use of the styled-components package.

import styled from 'styled-components/macro'

This simplifies the CSS process for the components used in this container.

NOTE: The macro included in the import, simplifies the class naming convention when the HTML is inspected.

index.js

This file references all the styled components in the JumbotronStyles.js and provides all the functions needed to construct the jumbotron.

The default function is used as the container or component wrapper:

export default function Jumbotron({ children, direction, ...restProps }) {
 return <Section direction={direction}>{children}</Section>
}

The props children and the …restProps (the rest of props) should always be included in this function. In our case we have also included the direction prop.

To build a compound component, use the following format:

Jumbotron.Container = function JumbotronContainer({ children }) {
 return <Container>{children}</Container>
}

NOTE: the use of the children prop.

The constrcution of the Jumbotron layout is done in the JumbotronContainer.js with the use of compound component method as follows:

<Jumbotron direction={direction}>
  <Jumbotron.Container>
    <Jumbotron.Title>{title}</Jumbotron.Title>
    <Jumbotron.Description>{description}</Jumbotron.Description>
    <Jumbotron.SubSection>
      <Jumbotron.SubContainer>
        <Jumbotron.SubImage src={sub1Image} alt={sub1Alt} />
        <Jumbotron.SubTitle>{sub1Title}</Jumbotron.SubTitle>
        <Jumbotron.SubDescription>
          {sub1Description}
        </Jumbotron.SubDescription>
      </Jumbotron.SubContainer>
      <Jumbotron.SubContainer>
        <Jumbotron.SubImage src={sub2Image} alt={sub2Alt} />
        <Jumbotron.SubTitle>{sub2Title}</Jumbotron.SubTitle>
        <Jumbotron.SubDescription>
          {sub2Description}
        </Jumbotron.SubDescription>
      </Jumbotron.SubContainer>
    </Jumbotron.SubSection>
  </Jumbotron.Container>
  <Jumbotron.Image src={image} alt={alt} />
</Jumbotron>

NOTE FOR NEWBIES: The images referenced in the jumbotronData.json actually refer to the those images located in the public/images folder (since the index.html located in the public folder is the one being rendered...).
