Component Library
The Lightning Component Library is your hub for Lightning UI developer information,
including the Component Reference, the Lightning Web Components developer guide, Lightning
Locker tools, and a code playground for Lightning web components.
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 this site without logging in to Salesforce. The Component Reference includes documentation and reference information for the base components.
- Component Library for your org
- View this site by logging in to your Salesforce org and navigating to https://<myDomain>/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 Lightning components that are unique to your org.
- View Lightning components that are installed in a managed package. You can filter to view components owned by your org or installed in packages.
- Use the global search feature to find documentation across the Component Reference and Lightning Web Components Developer Guide.
See Lightning Component Library in the Lightning Web Components Developer Guide for more information and known issues in the Component Reference.
