Intellisense stopped working for Typescript

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Errors and suggestions are not displayed, and “Go to definition” doesn’t work. I tried disabling all the extensions (except for “Vue - Official”, which I also tried downgrading the version of), and the problem did not go away. I tried it across multiple Nuxt projects and it’s all the same. At the same time, the IntelliSense works perfectly fine in the same projects on VSCode on the same machine.

Steps to Reproduce

Open any Nuxt project. Otherwise, I really don’t know how it happened. It just stopped working.

Operating System

Windows 10/11

Version Information

I tried uninstalling and installing multiple versions, including some snapshot of 2.6 I had initially when the issue appeared, then the latest 3.0 and the latest 2.5.
VSCode version: 1.105.1

Does this stop you from using Cursor

No - Cursor works, but with this issue

Solved by removing "typescript.experimental.useTsgo": true in settings.json.

Hey, thanks for the report. This looks like an issue with the TypeScript language server, so there are a couple things to check.

  1. Open View > Output, pick TypeScript in the dropdown. Open any .ts file and paste the log here. This is the main thing for debugging. It should show whether tsserver starts at all or crashes.

  2. Open the Command Palette with Ctrl+Shift+P and run TypeScript: Restart TS Server. Did that help?

  3. In the Extensions panel, make sure the built-in TypeScript Language Features extension is enabled. Also check if you have TypeScript Native Preview installed. If you do, disable it since it’s known to cause issues like this.

  4. Since reinstalling didn’t help, your local state probably didn’t get cleared. Try deleting the %APPDATA%\Cursor folder полностью, and save settings.json first just in case. Then restart Cursor.

The TypeScript Output log should show what’s actually going wrong, so please share it and we’ll take it from there.

When enabling "typescript.experimental.useTsgo": true, the typescript server seems to not be started, you don’t get any output for typescript and you cannot restart the server as it never started

@Justkant Hey, thanks for the detailed report and the video. Confirmed: "typescript.experimental.useTsgo": true currently breaks the TypeScript server in Cursor, it just won’t start.

For now, the only workaround is to remove this setting from settings.json, like the OP did.

I’ve passed this info to the team. We’ll update the thread if there’s any news.
