Patternfly setup in React Application

To order to integrate Patternfly framework into a ReactJS application, create a new project or use an existing one

npx create-react-app patternfly-setup-react

Install patternfly dependencies react-core, react-table and patternfly

npm i --save @patternfly/patternfly \
  @patternfly/react-core @patternfly/react-table

Note: Import base.css and patternfly.css in your project, or some components may diverge in appearance

//This imports are must to render css
import "@patternfly/react-core/dist/styles/base.css";
import "@patternfly/patternfly/patternfly.css";

To make sure everything is working correctly, update App.js with a demo layout from documentation

import React from "react";
import {
  Avatar,
  Brand,
  Button,
  ButtonVariant
  ...
  ...
} from "@patternfly/react-core";
import accessibleStyles from "@patternfly/react-styles/css/utilities/Accessibility/accessibility";
import spacingStyles from "@patternfly/react-styles/css/utilities/Spacing/spacing";
import { css } from "@patternfly/react-styles";
import { BellIcon, CogIcon } from "@patternfly/react-icons";

//This imports are must to render css
import "@patternfly/react-core/dist/styles/base.css";
import "@patternfly/patternfly/patternfly.css";

class App extends React.Component {
...
...
    return (
      <React.Fragment>
        <Page
          header={Header}
          sidebar={Sidebar}
          isManagedSidebar
          skipToContent={PageSkipToContent}
        >
        <PageSection variant={PageSectionVariants.light}>
            <TextContent>
              <Text component="h1">Main Title</Text>
              <Text component="p">
                Body text should be Overpass Regular at 16px. It should have leading of 24px because <br />
                of it’s relative line height of 1.5.
              </Text>
            </TextContent>
          </PageSection>
          <PageSection>
            <Gallery gutter="md">
              {Array.apply(0, Array(10)).map((x, i) => (
                <GalleryItem key={i}>
                  <Card>
                    <CardBody>This is a card</CardBody>
                  </Card>
                </GalleryItem>
              ))}
            </Gallery>
            </PageSection>
        </Page>
      </React.Fragment>
    );
  }
}
export default App;
