Lightning Components: More and Better Components to Accelerate Your Development

The Lightning Component framework powers Lightning Experience, Salesforce for Android, Salesforce for iOS, and Salesforce mobile web. Use the framework to build apps and pages for mobile devices, Lightning Experience, Salesforce Classic, and Communities.
Available in: Salesforce Classic and Lightning Experience
Available for use in: Contact Manager, Group, Professional, Enterprise, Performance, Unlimited, and Developer Editions

Create Lightning components using the UI in Enterprise, Performance, Unlimited, Developer Editions or a sandbox.

Use out-of-the-box components or build your own components with JavaScript, HTML, CSS, Apex, or any web-enabled code. Use AppExchange to get components created by Salesforce partners or publish your own.
