Lightning types are JSON-based data types used to structure, validate, and display
data. While Salesforce provides a set of standard Lightning types, you can create custom
Lightning types to customize the UI experience based on your business requirements.

- Custom Lightning Types Overview
Learn about custom Lightning types, the benefits they provide, and how field mapping works.
- Create a Custom Lightning Type
Define data structures and user interface configurations for supported platform features. You can base your type on an Apex class to ensure data consistency, or define a custom structure manually by using a JSON schema.
- Apex-Based Custom Lightning Types
An Apex-based custom Lightning type uses an Apex class to define its schema. Instead of manually creating fields, you map the type directly to your Apex class structure. This method is ideal when you have a complex data structure already defined in your Apex class code.
- Object-Based Custom Lightning Types
With an object-based custom Lightning type, you can define a schema manually by specifying fields. This method is ideal when you want to structure data without referencing an Apex class.
