using turborepo / monorepo and npm

[mdroidian]

Does patch-package support turborepo / monorepo using npm?

My repo has a similar structure to: https://github.com/vercel/turborepo/blob/main/examples/basic/README.md

Namely, each app / package (workspace) has a package.json but no package-lock.json, which gives me an error when trying to patch.

Steps to Repo

• navigate to workspace
  cd apps/myApp
• install patch-package
npm i patch-package --save-dev
• fix a bug in one of your dependencies
  vim node_modules/some-package/brokenFile.js
• run patch-package to create a .patch file
  npx patch-package some-package

Creating temporary folder
Error: Can't find yarn.lock file

It is throwing this error because it cannot find the package-lock.json in the workspace directory, so it assumes yarn.

patch-package/src/detectPackageManager.ts

Lines 44 to 45 in bd2e9a4

	const packageLockExists = fs.existsSync(
	join(appRootPath, "package-lock.json"),

Patch Package in root

The package/file I want to patch is located in the node_modules of the app / package (workspace).

apps/myApp/nod_modules/some-package

Is it possible to target that via npx patch-package some-package when running in the root directory?
