Paths with trailing slashes should be treated as directories

[NotWearingPants]

Using memfs:

const { fs } = require('memfs');
fs.writeFileSync('/foo', 'hello');
console.log(fs.readFileSync('/foo/', 'utf8')); // logs 'hello'

Using the builtin fs (on Linux):

const fs = require('node:fs');
fs.writeFileSync('/foo', 'hello');
console.log(fs.readFileSync('/foo/', 'utf8')); // throws ENOTDIR

Using the builtin fs (on Windows):

const fs = require('node:fs');
fs.writeFileSync('C:/foo', 'hello');
console.log(fs.readFileSync('C:/foo/', 'utf8')); // logs 'hello'

I think a trailing slash means the path is intended to point at a folder, so trying to read from it should throw.

Not sure why Windows is weird, maybe the behavior should differ based on isWin.

Tested with memfs v4.11.1 and Node.js v20.12.2

Have you tried your Windows test with \\ instead of /?

[NotWearingPants]

Yes, it still reads the file successfully

hmm interesting - that might be a bug in Node
