Lightning: Console JavaScript API
The Lightning Console JavaScript API gives you programmatic access to Lightning console apps, so you can fully integrate Lightning console apps with the Lightning framework and extend them to meet your business needs. In Spring ’18, we added the ability to use many of the Classic Salesforce Console Integration Toolkit APIs in Lightning Console. You can now use your existing Visualforce pages and third party Web Tabs containing JavaScript APIs in Lightning Console, without rewriting any of your code. Additionally, you can now use the openTab and openSubtab APIs to open Web Tabs in Lightning console apps.
