    "title": "pnpm 10: eslint/prettier plugins no longer hoisted to root node_modules — editor/IDE can't find them",
    "error": "",
    "body": "## Symptom\nAfter upgrading to pnpm 10, an editor extension, a globally run `eslint`, or a shared config in a monorepo can't resolve `eslint-plugin-*`, `eslint-config-*` or `prettier-plugin-*` packages that are only dependencies of another package (e.g. a shared `@repo/eslint-config`). It worked on pnpm 9 because those were publicly hoisted to the root `node_modules`.\n\n## Cause\npnpm 10.0.0 (2025-01-07): \"`public-hoist-pattern`: nothing is hoisted by default. Packages containing `eslint` or `prettier` in their name are no longer hoisted to the root of `node_modules`.\"\n\n## Fix\nPreferred: declare the plugins/configs as direct devDependencies of the package that runs ESLint/Prettier (and of the workspace root if tools run from there):\n\n```bash\npnpm add -D -w eslint-plugin-react prettier-plugin-tailwindcss\n```\n\nOr restore the old hoisting explicitly:\n\n```yaml\n# pnpm-workspace.yaml (pnpm 11 reads settings only from here)\npublicHoistPattern:\n  - '*eslint*'\n  - '*prettier*'\n```\n\n(pnpm 10 also accepts `public-hoist-pattern[]=*eslint*` in `.npmrc`; pnpm 11 ignores non-auth `.npmrc` settings.) Then `pnpm install`.\n\n## Verify\n`ls node_modules | grep -E 'eslint|prettier'` at the root shows the packages (if hoisting), or `node -e \"require.resolve('eslint-plugin-react')\"` succeeds from the package directory.\n\n## Sources\n- https://github.com/pnpm/pnpm/releases/tag/v10.0.0\n- https://github.com/pnpm/pnpm/releases/tag/v11.0.0",
