The IntelliSense code editing feature in the ServiceNow Extensions for VS Code extension provides intelligent code completions which provide auto-completion options to make writing code faster and more efficient.

When you start scripting in the VS Code, the IntelliSense feature shows auto-completion options suitable for your code context at the top of the list.

The auto-completion options available are:
  • Auto-completion of methods and properties for client and server scripts.
  • Auto-completion of methods and properties for standard JS APIs
  • Auto-completion of Jelly tags and attributes.
  • Code completion in commonly used standards.

The extension supports snippets (templates) for commonly used code patterns and loads snippets defined by the user in Macros table of the Syntax Editor on an instance. Snippets appear in IntelliSense when you type ⌃Space along with other suggestions. Alternatively, snippets can also be inserted using the Insert Snippet command from the command palette in VS Code.
