Make your purchase decisions only on the basis of generally available products and features.

Creating Apps

Components are the building blocks of an app. This section shows you a typical workflow to put the pieces together to create a new app.

First, you should decide whether you’re creating a component for a standalone app or for Salesforce apps, such as Lightning Experience or Salesforce for Android, iOS, and mobile web. Both components can access your Salesforce data, but only a component created for Lightning Experience or Salesforce for Android, iOS, and mobile web can automatically handle Salesforce events that take advantage of record create and edit pages, among other benefits.

The Quick Start walks you through creating components for a standalone app and components for Salesforce for Android, iOS, and mobile web to help you determine which one you need.
