Integrated-Benchmark Report (Linux)Commit: Regular scenarios report direct and pnpr installs. The peer-heavy resolver scenario compares current Rust, main Rust, and TypeScript pnpm; the linked-workspace scenario compares current Rust against main Rust. Bencher consumes pacquet@HEAD and pnpr@HEAD. The tables below show mean ± σ; Bencher thresholds on the minimum latency, which is far less perturbed by shared-runner contention (noise only adds time). Scenario: Isolated linker: fresh restore, cold cache + cold store

Use dynamic import for configured .js pnpmfiles. Node now applies the nearest package scope while CommonJS exports keep working. Refs pnpm#15141
The crate's tests cover the loader, but nothing pinned the install the issue reports, where the `pnpmfile` setting names a `.js` file. Add a CLI test that runs an install against both a module-scoped and a CommonJS-scoped `pnpmfile.js`, each written in syntax only its own format accepts, so the marker the hook writes names the format Node loaded. Reverting the finder's `.js` case makes it fail with ERR_PNPM_PNPMFILE_NOT_FOUND, the error the issue reports. Name each case of the `update_config` matrix, since three of its five entries share a file name, and take the warnings lock once instead of twice.

Every configured `.js` pnpmfile failed the install, CommonJS ones included, so a note about ES module loading covered only part of the fix. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>

The existence check behind the `pnpmfile` setting recognized only `.cjs` and `.mjs`, so a configured `.js` pnpmfile failed the install with ERR_PNPM_PNPMFILE_NOT_FOUND, and both hook execution paths read the module format off the extension. Recognize `.js` in the finder and load every pnpmfile through one shared CommonJS helper: `require` first, so a CommonJS pnpmfile keeps its complete `module.exports`, then dynamic `import()` when Node reports an ES module or an async one. Node then follows the nearest package scope. An ES module namespace is normalized back to its default export unless it exports `hooks`, `finders`, `resolvers`, or `fetchers` itself; a namespace without a default export is kept as is, so an empty ES module pnpmfile stays a no-op. Closes pnpm#15141. --------- Co-authored-by: Zoltan Kochan <[email protected]>

Summary
Closes #15141.
A configured
.jspnpmfile never reached Node. The existence check behind thepnpmfilesetting recognized only.cjsand.mjs, sopnpmfile: pnpmfile.jsfailed the install withERR_PNPM_PNPMFILE_NOT_FOUNDfor a file that was on disk. Both hook execution paths also read the module format off the extension and treated everything but.mjsas CommonJS.The finder now recognizes
.js, and both paths load the pnpmfile through one shared CommonJS helper. It starts withrequire, which keeps the completemodule.exportsof a CommonJS pnpmfile, and falls back to dynamicimport()when Node reports the file as an ES module or as an async one. Node therefore decides the format from the nearestpackage.json. An ES module namespace is normalized back to itsdefaultexport unless it exportshooks,finders,resolvers, orfetchersitself, soexport default { hooks }is honored while an empty namespace stays a harmless no-op.pnpm 11 loads a configured pnpmfile with
require, which already follows the nearestpackage.json, so the reporter's project works there and no pnpm v11 change is needed.Validation:
pnpmfilesetting namespnpmfile.js, once under"type": "module"and once under"type": "commonjs", and asserts which format the hook ran as. Reverting the finder's.jscase makes it fail with theERR_PNPM_PNPMFILE_NOT_FOUNDthe issue reports.pnpm test:rust -p pnpm-hooks -p pnpm-cli -E 'test(/^hooks::/) or package(pnpm-hooks)': 85 passed.
