Typescript autocompletion is laggy in VSCode

[kratico]

This is probably related to an update in the last 2 weeks

I'm also experiencing this problem.

There are two related open issues:

• Very slow intellisense (tab completion / ctrl+space menu) denoland/vscode_deno#824
• Intellisense/autocompletion is broken denoland/vscode_deno#825

I'd also imagine that this has something to do with LSP erroring out with the following mish mash on repeat:

Unable to send result to client.
successfully cancelled request with ID: 155
client asked to cancel request 153, but no such pending request exists, ignoring

These logs appear in denoland/deno#18494, which ultimately doesn't address editor responsiveness issues.

Things attempted

• disabling shiki
• emptying the Deno cache
• setting a new loc for the Deno cache
• loading old versions of Capi

EDIT:

Got a fun new log:

Hit the language server document preload limit of 1000 file system entries. You may want to use the "deno.enablePaths" configuration setting to only have Deno partially enable a workspace.

Explicitly setting all enablePaths––except for examples––in .vscode/settings.json solves it. This ofc is a bad solution for us, as we frequently develop against / debug via examples.
