Node doesn't seem having fs.promises.ftruncate (No doc entry for it, and also not available in runtime) https://nodejs.org/api/fs.html
Let's not expose it

You make a great point! I've noticed that fstat is also exposed but can't seem to find it in the doc, and fs.promises.fstat also doesn't seem to be available in the runtime. Is that an issue, and if so, is it something we would like to handle within this PR?

Good point. Yes, that seems an issue to me.

Fixing it in this PR is welcome, but that's not absolutely necessary in my opinon. I created an issue for fs.promises.fstat for now #27423

Awesome, I might take a deeper look into that one as well, see if we might have more to clean up :)
Also, the implementation for promises.ftruncate has been cleaned up 🧹

Probably we need to import ftruncatePromise directly from "ext:deno_node/_fs/_fs_ftruncate.ts"

Thanks for the PR! The test cases look good. I left some comments. |
