Create React App 2x

Bootstrap React App with create-react-app 2x and Salesforce Lightning Design System (SLDS) without ejecting the webpack config

Resources:

Sample Repo

Follow this repo at https://github.com/synle/create-react-app-salesforce-lightning to view a fully functional create-react-app 2x with Salesforce Lightning Design System

Requirements

Make sure you have node js version >=8. You can have it installed using nvm, n or just binary from your OS of choice

How to run this demo app

npm install
npm start

Step-by-step instruction

Bootstrap the app

npx create-react-app my-app
cd my-app
npm start

Override create-react-app webpack config

By default, create-react-app hides the webpack config from us, we need to use a package called rewire to modify the webpack config to properly install salesforce lightning

More on that here: https://github.com/timarney/react-app-rewired

npm install react-app-rewired --save-dev

Then changes the package.json scripts to use react-app-rewired

/* package.json */

"scripts": {
  "start": "react-app-rewired start",
  "build": "react-app-rewired build",
  "test": "react-app-rewired test --env=jsdom",
}

Customize the config-overrides.js for webpack

Create a new file called config-overrides.js with the following content

const path = require('path');

module.exports = function override(config, env) {
  config.module.rules = [
    // salesforce dependencies
    // this will compile salesforce lightning as src, not as package
    {
        test: /\.jsx?$/,
        include: [
          'node_modules/@salesforce/design-system-react',
        ].map(
          someDir => path.resolve(
            process.cwd(),
            someDir
          )
        ),
        loader: require.resolve('babel-loader'),
        options: {
          presets: [
            "react-app"
          ],
        },
    },
  ].concat(config.module.rules);

  return config;
}

Add salesforce lightning

npm install --save @salesforce-ux/design-system @salesforce/design-system-react

Copy over Salesforce Lightning static asset

Follow the instruction from Salesforce lightning website at https://github.com/salesforce/design-system-react/blob/master/docs/create-react-app.md

Overall, you need to copy the following items: CSS, Fonts, and icon SVGs

Salesforce Lightning CSS

cp node_modules/@salesforce-ux/design-system/assets/styles/salesforce-lightning-design-system.min.css public/

Salesforce Lightning Fonts

cp -r node_modules/@salesforce-ux/design-system/assets/fonts public/

Salesforce Lightning Icon SVGs

Note that here I copy the icons into public/assets instead of public as in the original guide from Salesforce Repo. The reason for this is that most code samples from the SLDS page reference the icon path from assets/icons.

mkdir -p public/assets
cp -r node_modules/@salesforce-ux/design-system/assets/icons public/assets

Salesforce Lightning Images / Illustrations

This is optional. But if you are using Salesforce Illustrations, make sure you copy over the illustrations files from Salesforce module

mkdir -p public/assets
cp -r node_modules/\@salesforce/design-system-react/assets/images public/assets/

Modify index.html to include Salesforce css

Add the following to your head tag

<link rel="stylesheet" type="text/css" href="/salesforce-lightning-design-system.min.css">

Change Salesforce IconSettings

In your index.js (root / entry point file) to set the path to Salesforce Icon. Just wrap it where you would normally mount your app.

import IconSettings from '@salesforce/design-system-react/components/icon-settings';


<IconSettings iconPath="/icons">
...
</IconSettings>
