Lightning Out, Components on Any Platform
Lightning Out Requirements
▪Lightning Components should be GLOBAL▪Lightning “Dependency” App
– Only top level components you intend to use▪Container Page supports <SCRIPT> import
– Import lightning.out.js library into the page▪Authentication is handled by the “container” or you!
– Session ID is available (e.g Visualforce page,)– Or implements oAuth
Lightning Out: Components on Any Platform
What about Google App Add-ons?
DemoIntegrating Lightning Components
in Google Documents via Google App Add-ons
Address Finder in Google Documents
Separation of Concerns means that the Address Finder component knows nothing of how the AddressInfo event will be handled. In this case by some Google App Script!AddressFinder.cmp
AddressInfo Event
What just happened?

Exposing your Components Lightning Out
Note: Inclusion of SLDS css file in Lightning “Dependency” App. Must be absolute path.
Using the Lightning Out JavaScript API
Note: Notice the class=”slds” being applied to the containing <div> element. Currently styles defined by the container are not imported by Lightning Out. Hence must be explicitly imported via the Lightning “Dependency” App.
Using the Lightning Out JavaScript API
Disclosure: $A.eventService is not presently documented. Follow source code link for an update on this code following this presentation.. Callback approach?
Google App Script and Lightning Out
▪oAuth is supported, but the user experience is not great
– See https://github.com/googlesamples/apps-script-oauth2
Google App Script Document API’s
▪Rich API’s for working with document content
▪Rich UI’s in HTML pose a challenge to traditional accessibility tools
▪Accessible Rich Internet Applications (Aria)– Research it and find out more at
https://www.w3.org/WAI/intro/aria.php ▪Lightning Design System
Examples adopting Aria!
