"The 'deno lsp' subcommand provides a way for code editors and IDEs to
interact with Deno using the Language Server Protocol. Usually humans do not
use this subcommand directly. For example, 'deno lsp' can provide IDEs with
go-to-definition support and automatic code formatting.
How to connect various editors and IDEs to 'deno lsp':
