Salesforce Lightning Design System

Welcome to the source code repository for Salesforce Lightning Design System, brought to you by Salesforce UX.

SLDS is...

• 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.

Getting Started

This project utilizes Storybook for component development. If you would like to know more about Storybook or how it works, check out their website.

Project Installation & Setup:

1. Clone the repository down locally.

2. cd

   into the project and run

   npm install

   to install all project dependencies.

Running the Development Environment:

The Storybook development environment can be started by running

npm start

Whenever you add, remove, or alter a component's css annotation metadata, you'll need to restart Storybook to see those changes.

Configuring Node and NVM

Node v12 is recommended for use with the Design System repository, and NVM is the recommended choice for managing multiple versions of Node on your computer.

A .nvmrc file is included in this project to aid in local development. To utilize it for setting your project's node version, run

nvm use
