### Where does the bug appear (feature/product)?

Cursor IDE

### Describe the Bug

The typescript version of the cursor IDE is downgraded the moment I import extensions from VS Code. I had to manually set my workspace config to overcome this. And because of this downgrade the RAM usage was so huge that my laptop used to crash.

### Steps to Reproduce

Open cursor in the Ubuntu machine. And then import extensions from VS Code. Now check the TS version.

Hey, I can see from the screenshot that “Use VS Code’s Version 5.3.0-dev.20230808” clearly points to an old global TypeScript install that your VS Code user-level `typescript.tsdk` was set to use.

When you import settings from VS Code, Cursor brings over most of your `settings.json`, including `typescript.tsdk` and `typescript.tsserver.*`. These keys don’t get filtered, so Cursor starts using the same old TS as VS Code. That’s why you’re seeing the downgrade, and it likely explains the high RAM usage too, old `tsserver` plus maybe an inherited `typescript.tsserver.maxTsServerMemory`.

What to do:

- Open user settings: `Cmd+Shift+P` or `Ctrl+Shift+P` then `Preferences: Open User Settings (JSON)`
- Remove or fix these keys:
  - `typescript.tsdk`
  - `typescript.tsserver.maxTsServerMemory`
  - any `typescript.tsserver.*` that you didn’t set yourself

- Restart the TS server: `Cmd+Shift+P` or `Ctrl+Shift+P` then `TypeScript: Restart TS Server`
- Check via `TypeScript: Select TypeScript Version`, “Use VS Code’s Version” should show the current bundled version in Cursor, not 5.3.0-dev.

The workspace override you already did is also a valid fix, but then you’d need to add `node_modules/typescript` manually in every new project.

Let me know if RAM usage improves after cleaning up the user settings.

This is my user settings JSON. I have already removed all those you mentioned and have nothing. But it always selects the old version.

Thanks for the `settings.json`. In user scope it really is clean. But `5.3.0-dev.20230808` is a TypeScript nightly build from August 2023. That usually comes from the TypeScript Nightly extension `ms-vscode.vscode-typescript-next`. It looks like it got installed during the VS Code import and is overriding the bundled TypeScript.

Please check two places:

- Extensions panel: find TypeScript Nightly publisher Microsoft id `ms-vscode.vscode-typescript-next`, then Disable or Uninstall it, then run `Developer: Reload Window`.
- Workspace settings in the project where you see the old version: open `.vscode/settings.json` and make sure there is no `typescript.tsdk` pointing to some global `node_modules/typescript`. You mentioned you did a workspace override as a workaround, so it might still be there.

After that, run `Cmd+Shift+P` or `Ctrl+Shift+P` then `TypeScript: Select TypeScript Version` and choose Use VS Code’s Version. You should see a current bundled 5.x there. Then run `TypeScript: Restart TS Server`.

If after removing Nightly it still shows 5.3.0-dev, please share the output of `TypeScript: Select TypeScript Version`. A screenshot of all options in the dropdown is enough, it will show where the path is coming from.

Thanks, it works. But can I know why there is a mismatch in the extension version? VS Code has version 6 for the same extension, but the Cursor has v5.3 for the same extensions.

Glad it’s working.

About the version difference: Cursor uses the Open VSX Registry at [openvsx.org](http://openvsx.org) as its extension source, while VS Code uses the proprietary Microsoft Marketplace. Microsoft doesn’t publish its extensions to OpenVSX, so anything starting with `ms-vscode.*` or `ms-python.*` including TypeScript Nightly `ms-vscode.vscode-typescript-next` gets mirrored there by third party maintainers and is usually behind in version. This isn’t a Cursor bug, it’s a marketplace limitation.

If you need the newest version of a Microsoft extension, you can download the `.vsix` from their GitHub Releases and install it via `Extensions: Install from VSIX...`, but for TypeScript Nightly in your case you don’t need that since the bundled TypeScript in Cursor is already up to date.
