Quick starts

Demo https://quickstarts.netlify.app/

Install

yarn add @patternfly/quickstarts

Peer dependencies

If your project doesn't already have these installed, you'll need:

yarn add @patternfly/react-core showdown

Stylesheets

In your web-apps entry point, add these stylesheets (these should be imported before modules from @patternfly/quickstarts are imported):

// base styles/variables for PatternFly-react
import '@patternfly/react-core/dist/styles/base.css';
// quick starts styles
import '@patternfly/quickstarts/dist/quickstarts.min.css';

Stylesheets if you use an older version of PatternFly

If you use an older version of @patternfly/react-core (older than "4.115.2"), and you can't upgrade yet, you can pull in the necessary PatternFly styles that @patternfly/quickstarts depends upon.

Ideally @patternfly/quickstarts will use the consumer provided PatternFly styles, only use these stylesheets if really needed.

quickstarts-standalone.min.css nests the css classes within a .pfext-quick-start__base parent, so that they have higher specificity. patternfly-global.css includes component styles that we cannot nest with more specificiy (for example Drawer since it can include consumer components that depend on an older PF version).

Note: Only use these stylesheets if necessary!

// import base from PatternFly to get the font
import '@patternfly/react-core/dist/styles/base.css';
// some global styles and variables that quickstarts uses (Drawer, Popover, Modal, Backdrop, Bullseye)
import '@patternfly/quickstarts/dist/patternfly-global.css';
// PF and quickstarts styles nested within .pfext-quick-start__base
import '@patternfly/quickstarts/dist/quickstarts-standalone.min.css';

Usage example

Note: You can also view this example on codesandbox!

// base styles/variables for PatternFly-react
import "@patternfly/react-core/dist/styles/base.css";
// quick starts styles

Design update, option to opt-out of new drawer header coloring

See above usage of useLegacyHeaderColors boolean to opt-out of update. Should only be used if new color scheme clashes with the usage context.

Quick starts format

Quick starts are parsed as markdown. To write your own quick start, if you use Typescript you can check out the type definition here.

Here's a yaml template to get you started on writing your own quick starts.

Writing quick starts

Quick starts are typically written in yaml, but we've also seen projects use asciidoc and json. As long as you can pass in an array of quick starts it doesn't really matter in what format your content is sourced.

• We have a yaml starter template here
• The easiest way to preview the content as you're writing it, is to use Visual Studio code with our quickstarts-preview extension.
  • Alternatively, you can use github.dev which is basically VS Code on the web, and install the extension there, then edit your yaml content!
• For guidelines on writing a quick start, the fine folks at OpenShift have created this guide

Highlighting elements

You can highlight an element on the page from within a quick start. The element that should be highlightable needs a data-quickstart-id attribute. Example:

<button data-quickstart-id="special-btn">Click me</button>

In the quick start task description, you can add this type of markdown to target this element:

Highlight [special button]{{highlight special-btn}}

Copyable text

You can have inline or block copyable text.

Inline copyable text example

`echo "Donec id est ante"`{{copy}}

Multiline copyable text example

    ```
      First line of text.
      Second line of text.
    ```{{copy}}

Markdown extensions

If your source material content is defined in markdown (yaml + markdown / json + markdown), then you can add your own markdown extensions, example:

const drawerProps: QuickStartContainerProps = {
  markdown: {
    extensions: [
      // variable substitution example
      // this replaces the strings [APPLICATION] and [PRODUCT]
      {
        type: 'output',
        filter: function(html: string) {
          html = html.replace(/\[APPLICATION\]/g, 'Mercury');
          html = html.replace(/\[PRODUCT\]/g, 'Lightning');

          return html;
        },
      },
    ],
  },
};

return <QuickStartContainer {...drawerProps}>My page content</QuickStartContainer>

Localization

We use English as the default language. You can override the default by providing your own key/value pairs to the QuickStartContainer or QuickStartContextProvider resourceBundle prop.

Example:

// load my own resource Czech translations resource bundle using i18next
const resourceBundle = i18n.getResourceBundle('cs', 'quickstart');
const resources = {
  ...resourceBundle,
  Start: "Let's go!",
  Continue: 'Resume',
  Restart: 'Start over',
};
return (
  <QuickStartContainer resourceBundle={resources}>
  </QuickStartContainer>
)

Use this file as a base for your translations. Each language is different, especially when it comes to plurals. Try this utility sourced from i18next to determine the suffixes for the right plural format.

For localizing the content of quick starts files, we provide the option to include language and countryCode key to your translated file. Based on these keys you can filter out quick starts. We have a demo of this behaviour in our demo app. You can have a look at the code here.

In-App / In Context Help Panel

The quickstarts package is being extended to support a side panel that displays smaller chunks (defined as the HelpTopic type) of documentation.

Help Topic type definition

type HelpTopicLink = {
  href: string;
  text?: string;
  // open link in new tab
  newTab?: boolean;
  // add PF icon indicating link is external
  isExternal?: boolean;
};

type HelpTopic = {
  name: string;
  title: string;
  tags: string[];
  content: string;
  links: HelpTopicLink[];
};

Example Help Topic in yaml with markdown support for content and links

- name: auto-deploy
  tags:
    - page-1
  title: Automatic Deployment
  content: |-
    **An Automatic Deployment** is...

      isExternal: true
    - text: 'Redhat Console (opens in new tab)'
      href: 'https://console.redhat.com'
      newTab: true

Usage Example

See the HelpTopicDemo

• Similar to standard Quickstarts usage
• Load yaml defined HelpTopic array
• Pass HelpTopicContainerProps, including loaded HelpTopics to the <HelpTopicContainer/>

import './App.css';
import { Page } from '@patternfly/react-core';
import { LoadingBox, HelpTopicContainerProps, HelpTopicContainer } from '@patternfly/quickstarts';
import { helpTopics } from './quickstarts-data/quick-start-test-data';
import React from 'react';
import i18n from './i18n/i18n';
import { AppHeader, AppSidebar } from './common/Page';

type AppProps = {
  children?: React.ReactNode;
  showCardFooters?: boolean;
};

const AppHelpTopicDemo: React.FC<AppProps> = ({ children }) => {
  const language = localStorage.getItem('bridge/language') || 'en';
  const resourceBundle = i18n.getResourceBundle(language, 'quickstart');

  const [loading, setLoading] = React.useState(true);
  React.useEffect(() => {
    const load = async () => {
      setLoading(false);
    };
    setTimeout(() => {
      load();
    }, 500);
  }, []);

  const inContextHelpProps: HelpTopicContainerProps = {
    helpTopics,
    resourceBundle,
    language,
    loading,
  };

  return (
    <React.Suspense fallback={<LoadingBox />}>
      <HelpTopicContainer {...inContextHelpProps}>
        <Page header={AppHeader} sidebar={AppSidebar} isManagedSidebar>
          {children}
        </Page>
      </HelpTopicContainer>
    </React.Suspense>
  );
};

In the example above <HelpTopicContainer /> wraps the <Page/> element as well as a mock "console" showing how to trigger the side panel and allow navigation to all HelpTopics available on each console page:
