Quick Start

This simple quick start shows you how to get started with Canvas by using the Heroku Quick Start. The Heroku Quick Start creates a “hello world” app on Heroku in either Java or Ruby, depending on the template you select. At the same time, it creates a corresponding canvas app in Salesforce.

The Heroku app is a “hello world” Web page that calls the Canvas SDK to display information about the current user and lets you post to the current user’s Chatter feed.

You can also specify where to display the Canvas app in Salesforce using the Canvas plugin for the external client app.
