What is aura definition bundle in Salesforce Lightning?

Hello Madhulika,

A bundle contains a Lightning definition and all its related resources. The definition can be a component, application, event, interface, or a tokens collection.

Unlike other metadata components, an AuraDefinitionBundle component isn’t represented by a single component file but instead by a collection of component definition files. Each definition file represents a resource in a bundle, such as markup, applications, code files (including controllers and helpers), events, documentation, and interfaces.This object is available in API version 32.0 and later.

Hi

An AuraDefinitionBundle component is a collection of component definition files, each representing a different resource such as markup code, event documentations, applications and interfaces.

Aura definition bundle contains following items:

Component: UI for lightning component

controller.js: Contains client-side controller methods to handle events in the component.

helper.js: JavaScript functions that can be called from any JavaScript code in a component’s bundle

style: Contains styles for the component.

design: File required for components used in Lightning App Builder, Lightning pages, or Community Builder.

renderer: Client-side renderer to override default rendering for a component.

documentation: A description, sample code, and one or multiple references to example components

SVG: Custom icon resource for components used in the Lightning App Builder or Community Builder.

Thanks
