ReadableStream.from not supported if a fresh app is a subfolder about fresh

Based on the issue title and the description I tried to guess how you're using ReadableStream.from, but I feel like the description is missing that part. Can you share more about that? How do we reproduce the issue?

Sorry about vague description. By “I can not use” I meant that vscode doesn’t like the “from” word of ReadableStream.from([1, 2, 3]) expression and gives the following info in the tooltip:

Property 'from' does not exist on type '{ new (underlyingSource: UnderlyingByteSource, strategy?: { highWaterMark?: number | undefined; } | undefined): ReadableStream; new <R = any>(underlyingSource: UnderlyingDefaultSource<...>, strategy?: QueuingStrategy<...> | undefined): ReadableStream<...>; new <R = any>(underlyingSource?: UnderlyingSourc...'.deno-ts(2339)

The script runs and deno check gives no issues about it. So I guess this issue is related to vscode. Please let me know what else is missing

If it helps, I shared my deno.jsonc in this issue, it’s still the same.

Thanks for providing more context. This sounds like it's a type issue. Does removing the tripple slash comments in main.ts and dev.ts help?

[sergeysolovev]

Oh I see. I don’t have tripple slash comments in dev.ts. Removing the from main.ts doesn’t help with the issue.

I think the issue here is that Preact always loads dom types, and Deno LSP does not support different global types in different folders of a project. cc @nayeemrmn
