jsr: deps not in node_modules

[lishaduck]

Version: Deno 2.x.x (all)

When using jsr: deps via a deno.json file and using "nodeModulesDir": "manual" or (I forget, I think so ?) "nodeModulesDir": "auto" they aren't included in the node_modules dir, which causes issues with Vitest (#23882 (comment)).
When using a package.json with a JSR-enabled .npmrc, deno install works as expected.

I assume you'll want a repro; I need to go hit the hay, so, if so, please ping me so it's at the top of my notifications list tomorrow :)

This is by design. jsr: specifiers in Deno resolve to remote https urls (ex. jsr:@std/[email protected] resolves to https://jsr.io/@std/path/1.0.8/mod.ts) and so they aren't included in the node_modules directory (they can be included locally in a project by turning on "vendor": true in a deno.json, at which point they'll be in the local vendor folder).

That said, it is possible to use JSR packages with a node_modules directory by installing them through npm by adding the following to an .npmrc file:

@jsr:registry=https://npm.jsr.io

Then importing them via an npm:@jsr/... specifier or adding them as a dependency in a package.json file (https://jsr.io/docs/using-packages#adding-a-package)
