§ Context contains data like:
• Scoped OAuth Token
• User Info (Name, email, ID, etc..)
• Company Info (Company name, ID, etc…)

§ The Warehouse App is a walkthrough provided by salesforce which
explains the customizability of the salesforce.com app
• The app takes you through the declarative and integration capabilities of
salesforce.com
• The full workbook can be found at
http://www.salesforce.com/us/developer/docs/workbook/forcecom_workbook.pdf
§ The Force.com Canvas App will represent a fulfillment center that your
warehouse app will use
• Picture salesforce.com as your sales center, and the Web App your fulfillment/
shipping center…Force.com Canvas allows you to interact with both apps

20. Heroku: A Multi-language Cloud App Platform

21. Canvas Demo

22. Combining the Fulfillment App with the Warehouse App
§ Fulfilment data now exposed inside of the Chatter tab

23. Exposing a Canvas App in a Visualforce Page
§ Spring ‘13 introduces the ability to drop a Canvas App in a Visualforce Page
• Use the new <apex:canvasApp /> tag
• The required information is:
– applicationName –The full name of the app
– namespacePrefix – The namespace of the Canvas App
– developerName – The developer name of the app (found on the app detail page)
• Optional information includes:
– height – The height of your canvas
– width – The width of your canvas
– border – The width of the border around your canvas
– scrolling – Indicates if the canvas should have scroll bars
– parameters – JSON string to pass in the Context sent to the app

24. Using apex:canvasApp
<apex:page showheader="false">
<apex:canvasApp applicationName="Fulfillment App”
height="1000px" width="800px” parameters="{'myValue' : 'value1'}” />
</apex:page>

25. Exposing a Canvas App in a Visualforce Tab
§ Extending the ability to add a Canvas App in a Visualforce Page, you can
also create a Visualforce Tab

26. Adding a Canvas App into a Record Detail Page
§ By adding a Canvas App to a Visualforce Page, you can also embed
the app in a Record Detail page
§ This will allow you to visually deliver content directly on your records

27. Passing Parameters to your Canvas App
§ Using the “parameters” element of apex:canvasApp alows you to pass
custom information to your Canvas App
§ This will allow you to dynamically render you app information
§ Ex – You can pass a Salesforce Record ID and display the
appropriate related record from the 3rd Party App
<apex:page sidebar="false" showheader="false" standardController="Invoice_Statement__c">
<apex:canvasApp developerName="denv_warehouse"
parameters="{'orderId':'{!Invoice_Statement__c.id}','name':
'{!HTMLENCODE(Invoice_Statement__c.name)}'}" width="800px" height="380px"
scrolling="false"/>
</apex:page>

28. Dynamically Rendering Content
§ By extracting the parameters from the signed request or context, you
can render specific data
§ Ex - Show record specific information inline

§ Walked through the new features of Force.com Canvas in Spring ‘13
