- 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.

Tasks
Install gulp globally:
npm install --global gulp
gulp
Generate and run the Lightning Design System.
gulp serve

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.
gulp lint
gulp lint:sass
gulp lint:js
gulp lint:js:test
gulp lint:spaces
gulp lint:html
gulp lint:vnu (optional: --component "{trees_base_with*,trees_base_deep*}")
Compilation

Delete temporary build and local files.
Stats

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.
If Node.js is already installed, make sure you’re running v6 or up.
Ruby dependencies
Ruby comes pre-installed on macOS. 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 v3.10. You can update your npm with: npm install npm -g
(sudo
may be required). - Re-install dependencies:
rm -Rf node_modules && npm install
npm start
If this did not work, try running npm cache clean
and repeat the above steps.
