描述

It should be cool if tsserver could provide a new command guesstypes to give the capability to guess parameter types when completion is applied

In other word, I would like to support the same feature that I have done with tern

For instance if you open completion for document and select addEventListener :

Tern completion

When you apply completion, I would like call a tsserver command 'guesstypes' to retrieve variables, functions for each function parameters. Here a screenshot which shows a list of variable with string type for the addEventListener type argument :

Tern completion

研究方向
Examine TypeScript's completion service in src/services/ and tsserver command handling. Reference the tern guess types project for a similar implementation. Investigate how to add a new command (e.g., 'guesstypes') that retrieves type suggestions based on contextual type after a completion item is selected. Consider how to integrate with the existing completion pipeline and expose type information to the editor.
