VS Code extension causing JS/TS language service crashes last couple of days

[ahkelly]

Describe the bug

type intellisense is perpetually in "loading state" and the VS code typescript plugin is repeatedly crashing returning ultimately the following notice.

"The JS/TS language service crashed 5 times in the last 5 Minutes. This may be caused by a plugin contributed by one of these extensions: svelte.svelte-vscode Please try disabling these extensions before filing an issue against VS Code."

Reproduction

Install vs code in wsl ubuntu and a normal svelte install with default options (svelte 4) using javascript with JSDoc checking.

jsconfig.json

{
	"extends": "./.svelte-kit/tsconfig.json",
	"compilerOptions": {
		"allowJs": true,
		"checkJs": true,
		"esModuleInterop": true,
		"forceConsistentCasingInFileNames": true,
		"resolveJsonModule": true,
		"skipLibCheck": true,
		"sourceMap": true,
		"strict": true,
		"moduleResolution": "bundler"
	}
	// Path aliases are handled by https://kit.svelte.dev/docs/configuration#alias
	// except $lib which is handled by https://kit.svelte.dev/docs/configuration#files
	//
	// If you want to overwrite includes/excludes, make sure to copy over the relevant includes/excludes
	// from the referenced tsconfig.json - TypeScript does not merge them in
}

Expected behaviour

Normal behaviour is the language server not crashing in vs code.

I can't reproduce this can you follow this instruction to get the log of TSServer and see if there is any error in it? https://github.com/microsoft/TypeScript/wiki/Getting-logs-from-TS-Server-in-VS-Code

Hallelujah! I believe I have found the culprit. I took a look at any major changes I may have made in last few days that could have also contributed to it and I remembered I started integrating google cloud apis into our application which I disabled because at build time I was getting the ugly circular reference node error as mentioned and unresolved here

googleapis/google-auth-library-nodejs#1539

I reverted my code but left the packages installed so I could get back to this once finding a resolution. These packages (all from google) were

• @google-analytics/data
• googleapis
• @googleapis/searchconsole

I removed them today completely and restarted vs code and presto problem solved so they were clashing with this extension (not sure which one or all of them)

I still can't reproduce the problem with all three libraries installed. But seems like you have solved your issue so I'll close this in a few days if there is no further info we can investigate.

OK, So the issue does still pop-up from time to time but not always like it was before I uninstalled the aforementioned packages.
The only somewhat consistent thing I can see that "may" be the cause is that whenever I have some invalid JavaScript code (invalid expression or function for example) this seems to trigger the freak out if I leave the code uncorrected for an extended period of time.

Sounds like it may be something unique to my installation so probably not worth looking any further until I can reliably find more reproduction steps and I am not going to spam you with the tons of log data that has been generated as most of it is INFO lines and I don't see much in there that stands out.
