The root contains functional directories organized by domain:\n\n### Core Directories\n\n- `pnpm/`: The CLI entry point and main package.\n- `pkg-manager/`: Core package management logic (installation, linking, etc.).\n- `resolving/`: Dependency resolution logic (resolvers for npm, tarballs, git, etc.).\n- `fetching/`: Package fetching logic.\n- `store/`: Store management logic (content-addressable storage).\n- `lockfile/`: Lockfile handling, parsing, and utilities.\n\n### CLI & Configuration\n\n- `cli/`: CLI command implementations and infrastructure.\n- `config/`: Configuration management and parsing.\n- `hooks/`: pnpm hooks (readPackage, etc.).\n- `completion/`: Shell completion support.\n\n### Other Functional Directories\n\n- `network/`: Network-related utilities (proxy, fetch, auth).\n- `workspace/`: Workspace-related utilities.\n- `exec/`: Execution-related commands (run, exec, dlx).\n- `env/`: Node.js environment management.\n- `cache/`: Cache-related commands and utilities.\n- `patching/`: Package patching functionality.\n- `reviewing/`: License and dependency review tools.\n- `releasing/`: Release and publishing utilities.\n\n### Shared Utilities\n\n- `packages/`: Shared utility packages (constants, error handling, logger, types, etc.).\n- `fs/`: Filesystem utilities.\n- `crypto/`: Cryptographic utilities.\n- `text/`: Text processing utilities.\n\n## Setup & Build\n\nTo set up the environment and build the project:\n\n```bash\npnpm install\npnpm run compile\n```\n\n## Testing\n\nNever run all tests in the repository as it takes a lot of time.\n\nRun tests for a specific project instead:\n\n```bash\n# From the project directory\npnpm test\n\n# From the root, filtering by package name\npnpm --filter test\n```\n\nOr better yet, run tests for a specific file:\n\n```bash\npnpm --filter test \n```\n\nOr a specific test case in a specific file:\n\n```bash\npnpm --filter test -t \n```\n\n## Linting\n\nTo run all linting checks:\n\n```bash\npnpm run lint\n```\n\n## Contribution Workflow\n\n### Changesets\n\nIf your changes affect published packages, you MUST create a changeset file in the `.changeset` directory. The changeset file should describe the change and specify the packages that are affected with the pending version bump types: patch, minor, or major.\n\n**IMPORTANT: Always explicitly include `\"pnpm\"` in the changeset** with the appropriate version bump (patch, minor, or major). The pnpm CLI will only receive automatic patch bumps from its dependencies, so if your change warrants a minor or major version bump for the CLI, you must specify it explicitly. The changeset description will appear on the release notes page.\n\nExample:\n\n```\n---\n\"@pnpm/core\": minor\n\"pnpm\": minor\n---\n\nAdded a new setting `blockExoticSubdeps` that prevents the resolution of exotic protocols in transitive dependencies [#10352](https://github.com/pnpm/pnpm/issues/10352).\n```\n\n**Versioning Guidelines for pnpm CLI:**\n- **patch**: Bug fixes, internal refactors, and changes that don't require documentation updates\n- **minor**: New features, settings, or commands that should be documented (anything users should know about)\n- **major**: Breaking changes\n\n### Commit Messages\n\nFollow the [Conventional Commits](https://www.conventionalcommits.org/) specification.\n - `feat`: a new feature\n - `fix`: a bug fix\n - `docs`: documentation only changes\n - `style`: formatting, missing semi-colons, etc.\n - `refactor`: code change that neither fixes a bug nor adds a feature\n - `perf`: a code change that improves performance\n - `test`: adding missing tests\n - `chore`: changes to build process or auxiliary tools\n\n## Code Style\n\nThis repository uses [Standard Style](https://github.com/standard/standard) with a few modifications:\n- **Trailing commas** are used.\n- **Functions are preferred** over classes.\n- **Functions are declared after they are used** (hoisting is relied upon).\n- **Import Order**:\n 1. Standard libraries (e.g., `fs`, `path`).\n 2. External dependencies (sorted alphabetically).\n 3. Relative imports.\n\nTo ensure your code adheres to the style guide, run:\n\n```bash\npnpm run lint\n```\n\n## Common Gotchas\n\n### Error Type Checking in Jest\n\nWhen checking if a caught error is an `Error` object, **do not use `instanceof Error`**. Jest runs tests in a VM context where `instanceof` checks can fail across realms.\n\nInstead, use `util.types.isNativeError()`:\n\n```typescript\nimport util from 'util'\n\ntry {\n // ... some operation\n} catch (err: unknown) {\n // ❌ Wrong - may fail in Jest\n if (err instanceof Error && 'code' in err && err.code === 'ENOENT') {\n return null\n }\n \n // ✅ Correct - works across realms\n if (util.types.isNativeError(err) && 'code' in err && err.code === 'ENOENT') {\n return null\n }\n throw err\n}\n```\n\n## Key Configuration Files\n\n- `pnpm-workspace.yaml`: Defines the workspace structure.\n- `package.json` (root): Root scripts and devDependencies.\n- `CONTRIBUTING.md`: Detailed contribution guidelines.\nimport defaultFS from 'node:fs'\nimport { pathTemp } from 'path-temp'\n\nexport async function canWriteToDir (dir, customFS) {\n const fs = customFS || defaultFS\n const tempFile = pathTemp(dir)\n try {\n await fs.promises.writeFile(tempFile, '', 'utf8')\n fs.promises.unlink(tempFile).catch(() => {})\n return true\n } catch (err) {\n if (err.code === 'EACCES' || err.code === 'EPERM' || err.code === 'EROFS') {\n return false\n }\n throw err\n }\n}\n\nexport function canWriteToDirSync (dir, customFS) {\n const fs = customFS || defaultFS\n const tempFile = pathTemp(dir)\n try {\n fs.writeFileSync(tempFile, '', 'utf8')\n fs.unlinkSync(tempFile)\n return true\n } catch (err) {\n if (err.code === 'EACCES' || err.code === 'EPERM' || err.code === 'EROFS') {\n return false\n }\n throw err\n }\n}\nexport function canWriteToDir (dir: string): Promise\nexport function canWriteToDirSync (dir: string): boolean\nimport { promises as fs } from 'fs'\nimport path from 'path'\nimport util from 'util'\nimport { PnpmError } from '@pnpm/error'\nimport { sync as canWriteToDir } from 'can-write-to-dir'\nimport PATH from 'path-name'\n\nexport async function checkGlobalBinDir (\n globalBinDir: string,\n { env, shouldAllowWrite }: { env: Record, shouldAllowWrite?: boolean }\n): Promise {\n if (!env[PATH]) {\n throw new PnpmError('NO_PATH_ENV',\n `Couldn't find a global directory for executables because the \"${PATH}\" environment variable is not set.`)\n }\n if (!await globalBinDirIsInPath(globalBinDir, env)) {\n throw new PnpmError('GLOBAL_BIN_DIR_NOT_IN_PATH', `The configured global bin directory \"${globalBinDir}\" is not in PATH`)\n }\n if (shouldAllowWrite && !canWriteToDirAndExists(globalBinDir)) {\n throw new PnpmError('PNPM_DIR_NOT_WRITABLE', `The CLI has no write access to the pnpm home directory at ${globalBinDir}`)\n }\n}\n\nasync function globalBinDirIsInPath (globalBinDir: string, env: Record): Promise {\n const dirs = env[PATH]?.split(path.delimiter) ??
