Create LightningTypeBundle metadata to define data structures by using JSON Schema. Build flexible, object-based types for use in Experience Builder, Prompt Builder, and other supported Salesforce applications. Define schemas directly in the metadata to simplify development and deployment.
Where: This change applies to Lightning Experience in Enterprise, Performance, Unlimited, and Developer editions.
When: This feature is available on a rolling basis starting the week of February 9, 2026.
How: When you create a LightningTypeBundle component, use the
schema.json file to specify the properties. Ensure this file doesn’t
reference an Apex class via the lightning:type keyword when you define the
structure manually.
