Component Library
The Lightning Component Library is your hub for Lightning UI developer information,
including the Component Reference with live examples, the Lightning Web Components developer
guide, and tools for Lightning Web Security and Lightning Locker.
You can find the Component Library in two places: a public site and an authenticated one
that’s linked to your Salesforce org. In the authenticated site, the Component Reference
section of the Component Library has some additional features.
- Public Component Library
- View the public site https://developer.salesforce.com/docs/component-librarywithout logging in to Salesforce. The Component Reference includes documentation and reference information for the base Lightning components.
- Component Library for your org
- View this site by logging in to your Salesforce org and navigating to https://MyDomainName.my.salesforce.com/docs/component-library. Alternatively, click Link to your org at the top right on the public site.
- The authenticated site has additional features for the Component Reference.
- View Aura Lightning components that are unique to your org.
- View Aura Lightning components that are installed in a managed package. You can filter to view components owned by your org or installed in packages. Find the filtering options at https://MyDomainName.my.salesforce.com/docs/component-library/overview/components and expand the Filters list to find the Owners filters.
See Lightning Component Library in the Lightning Web Components Developer Guide for more information and known issues in the Component Reference.
