Any way to increase memory for VS code extension?

[AndreasHald]

My extension crashes with the following

Initialize language server at  file:///Users/xxx/Documents/eddystone

I know this is most likely related to excessive use of types and should probably be debugged why it's attempting to use so much memory, but in the meantime - is there anyway I can simply give the extension 8 or 16gb of memory?

[jasonlyu123]

You could probably use the svelte.language-server.runtime-args config to increase the memory limit. But this is most likely a misconfiguration with your include and exclude config in the tsconfig.json. You need to exclude or not include the build outputs.

Normally, there should be a size check to prevent crashes; maybe you disabled it while debugging the size limit warning?

[AndreasHald]

I don't think so? where would I have disabled it?

[AndreasHald]

"svelte.language-server.runtime-args": ["--max-old-space-size=8192"]

This does not appear to work

<--- JS stacktrace --->

Still seems like it's crashing around 4gb

[jasonlyu123]

I still think it is more likely to be a problem with your tsonfig.json. You need to check if the "include" config matches any build output. 4000 source files in a single project doesn't sound right.

[AndreasHald]

After having investigated this further, I don't think this is a tsconfig issue, I can't find any build output as part of the tsconfig, it is quite a large project however.

I think the issue is downstream from this one https://x.com/arktypeio/status/1905293040064790541 ie a typescript issue when inferring types from in our case zod objects. We do this quite a lot.

While waiting for a resolution for this do you have any other suggestions for increasing the memory other than
"svelte.language-server.runtime-args": ["--max-old-space-size=8192"]

[jasonlyu123]

If that is the case, it sounds like a typescript issue. Then you either have to report to TypeScript or ArkType. You might have to check when this started to happen, and maybe you can narrow down the files that might be the problem.

[AndreasHald]

I agree, it's a typescript issue and it sounds like it's being worked on on the typescript side, so it'll most likely go away eventually, and you are right, I could fix it on my side by reducing our usage of type inference to reduce the typescript overhead. all that being said, it would be nice to be able to temporarily change the memory for the plugin, so it can still work while either waiting for a typescript fix or reducing our reliance on what's causing the issue.

[Axeldeblen]

@AndreasHald.
We also have a very large svelte project with ~8000 svelte files. I'm guessing there might be a memory leak in the last update to the extension because after looking at this a bit yesterday in our project it seems downgrading to the previous Svelte for VS code extension release 109.5.2 has resolved the issue for us.
