Patternfly Data Virtualization Training Workshop

Quick-start

git clone https://github.com/rh-uxd/data-virtualization-training-workshop.git # clone the project
cd data-virtualization-training-workshop # navigate into the project directory
npm install # install patternfly-react-seed dependencies
npm run build # build
npm run start:dev # start the development server

Development Scripts

Install development/build dependencies npm install

Start the development server npm run start:dev

Run a production build (outputs to "dist" dir) npm run build

Run the test suite npm run test

Run the linter npm run lint

Run the code formatter npm run format

Launch a tool to inspect the bundle size npm run bundle-profile:analyze

Start the express server (run a production build first) npm run start

Start storybook component explorer npm run storybook

Build storybook component explorer as standalone app (outputs to "storybook-static" dir) npm run build:storybook

Configurations

• TypeScript Config
• Webpack Config
• Jest Config
• Editor Config

Raster Image Support

To use an image asset that's shipped with patternfly core, you'll prefix the paths with "@assets". @assets is an alias for the patternfly assets directory in node_modules.

For example:

import imgSrc from '@assets/images/g_sizing.png';
<img src={imgSrc} alt="Some image" />

You can use a similar technique to import assets from your local app, just prefix the paths with "@app". @app is an alias for the main src/app directory.

import loader from '@app/assets/images/loader.gif';
<img src={loader} alt="Content loading />

Vector Image Support

Inlining SVG in the app's markup is also possible.

import logo from '@app/assets/images/logo.svg';
<span dangerouslySetInnerHTML={{__html: logo}} />

You can also use SVG when applying background images with CSS. To do this, your SVG's must live under a bgimages directory (this directory name is configurable in webpack.common.js). This is necessary because you may need to use SVG's in several other context (inline images, fonts, icons, etc.) and so we need to be able to differentiate between these usages so the appropriate loader is invoked.

body {
  background: url(./assets/bgimages/img_avatar.svg);
}

Code Quality Tools

• For accessibility compliance, we use react-axe
• To keep our bundle size in check, we use webpack-bundle-analyzer
• To keep our code formatting in check, we use prettier
• To keep our code logic and test coverage in check, we use jest
• To ensure code styles remain consistent, we use eslint
• To provide a place to showcase custom components, we integrate with storybook

Multi environment configuration

This project uses dotenv-webpack for exposing environment variables to your code. Either export them at the system level like export MY_ENV_VAR=http://dev.myendpoint.com && npm run start:dev or simply drop a .env file in the root that contains your key-value pairs like below:

ENV_1=http://1.myendpoint.com
ENV_2=http://2.myendpoint.com

With that in place, you can use the values in your code like console.log(process.env.ENV_1);
