Salesforce Lightning Design System

Welcome to the Salesforce Lightning Design System brought to you by Salesforce UX.

Tailored for building Salesforce apps: Using the Lightning Design System markup and CSS framework results in UIs that reflect the Salesforce Lightning look and feel.
Continuously updated: As long as you’re using the latest version of the Lightning Design System, your pages are always up to date with Salesforce UI changes.

Quick start

gem install bundler
npm install
npm start

Having trouble getting these steps to work on your machine? Follow the troubleshooting guide below.

Tasks

Install gulp globally:

npm install --global gulp

`gulp`

Generate and run the Lightning Design System.

`gulp serve`

Run the lightning design system.

Faster than gulp, as it won't re-generate the whole site before starting the server. Useful when mainly working on styles.

`gulp lint`

Lint the code base for syntax and stylistic errors.

# Lint indentation, Sass, JavaScript files
gulp lint

# Lint languages independently
gulp lint:sass
gulp lint:js
gulp lint:js:test
gulp lint:spaces
gulp lint:html

Compilation

gulp pages: generate the site’s pages.

gulp styles: compile Sass to CSS.

`gulp clean`

Delete temporary build and local files.

Stats

npm run stats: Useful stats about the project's deliverables.

Tests

npm test: run all tests

Troubleshooting

npm and Node.js

The Salesforce Lightning Design System uses npm to manage dependencies. Please install Node.js, and try running npm install again.

Ruby dependencies

Ruby comes pre-installed on Mac OS X. For other systems, check https://www.ruby-lang.org.

If gem install bundler fails, run sudo gem install bundler and try running npm install again.

JavaScript and compilation issues

JavaScript dependencies sometimes get out of sync and inexplicable bugs start to happen. Follow these steps to give a fresh start to your development environment:

The installed npm version must be at least 2.1.x. You can update your npm with: sudo npm install npm -g.
Re-install dependencies: rm -Rf node_modules && npm install
npm run gulp

If this did not work, try running npm cache clean and repeat the above steps.
