React monorepo preset base configuration contains conflicting peer dependency

[Revinz]

Current Behavior

Creating a workspace with react-monorepo preset leads to "npm i" and future npm package installations to give a conflicting peer dependency error.

Expected Behavior

Ability to install new packages and generate node modules using npm install

GitHub Repo

No response

Steps to Reproduce

1. npx create-nx-workspace@latest test --preset=react-monorepo
2. Application name irrelevant
3. Bundler=Rspack
4. Testrunner=None
5. Stylesheet format=styled-components
6. CI=GitHub Actions
7. Navigate to workspace root
8. run npm install
9. Error: While resolving: eslint-plugin-import@2.30.0

Edit: Also occurs with Vite and Webpack as bundler. Both results in the same error, meaning this is a major issue as the preset do not work at all.

Additional Information

Related issue from eslint-plugin-import regarding eslint v9 support can be found here. Includes potential workaround that I have not tested: import-js/eslint-plugin-import#2948

The issue that have introduced this problem is most likely this one: #27451

[ziacik]

Also, @nx/esbuild@19.8.2 uses esbuild@~0.19.2 as peer dep
while @nx/vite@19.8.2 installs vite@5.4.8 which uses esbuild@^0.21.3 as dep,
bringing two sets of binaries to node_modules.

This is hell. :(

[jeff-edmondson-pci]

Seeing this as well. Is there any resolution?

[lundinmathias]

I ran into this as well while following the tutorial https://nx.dev/getting-started/tutorials/react-monorepo-tutorial. Used --legacy-peer-deps to be able to move on.

[Bullfrog1234]

So doing a bit of research I have found the following

Packages with support for ESLint v9

• eslint-plugin-import@2.31.0: added support for ESLint v9
• eslint-plugin-jsx-a11y@6.10.0: added support for ESLint V9
• eslint-plugin-react@7.35.0: added support for ESlint v9, however the library is now on v7.37.1

Packages without support for ESLint v9

eslint-plugin-react-hooks

The issue is eslint-plugin-react-hooks it has no support for v9 of ESLint. There is anan open issue (react#28313) which talks about the flat file nature of v9 and a PR react#30774 that add support for a flat configuration. This however does not include an updated peer dependencies for v9 in the package.

Temporary Solution

Add an override for eslint-plugin-react-hooks in package.json:

{
 "name": "@demo/source",
  "version": "0.0.0",
  "devDependencies":{
    "eslint": "^9.8.0",
    "eslint-config-prettier": "^9.0.0",
    "eslint-plugin-import": "2.31.0",
    "eslint-plugin-jsx-a11y": "6.10.0",
    "eslint-plugin-react": "7.37.1",
    "eslint-plugin-react-hooks": "4.6.0",
  },
  "overrides": {
    "eslint-plugin-react-hooks": {
      "eslint": "^9.8.0"
    }
  }
}

Experiencing this issue as well even without using a preset, but by just adding the react-app via nx g @nx/react:app app --bundler=vite

Would it be safe to downgrade eslint instead?

[isaacplmann]

Should be resolved by #28267

[Bullfrog1234]

Should be resolved by #28267

@isaacplmann This does not fix all the peer dependency issues that are caused by the upgrade. Additionally, some of the plugins do not support v9 see above

Can confirm the issue is happening in Nx 20. We're a little slow this week since the whole team is at Monorepo World.

@Bullfrog1234 's workaround should work for v20 as well.

[sacru2red]

eslint-plugin-react-hooks start to support eslint v9
https://github.com/facebook/react/releases/tag/eslint-plugin-react-hooks%405.0.0

I got errors with Nx Monorepo tutorial

resolve with npm install eslint-plugin-jsx-a11y@latest eslint-plugin-react-hooks@latest

[laszlo-ratesic]

@Bullfrog1234's workaround didn't fully solve it for me as I'm using the nextjs starter, but I had the same peer conflicting deps error. I was able to install packages with --legacy-peer-deps but ran into issues when trying to use shadcn/ui CLI so I needed something that would work without the flag.

I ended up changing my package.json's devDependencies and overrides to this

"devDependencies": {
    // other dependencies...
    "@typescript-eslint/eslint-plugin": "^7.2.0",
    "@typescript-eslint/parser": "^7.2.0",
    "eslint": "8.56.0",
    "eslint-config-next": "14.2.3",
  },
  "overrides": {
    "eslint": "8.56.0",
    "@typescript-eslint/eslint-plugin": {
      "eslint": "8.56.0"
    },
    "@typescript-eslint/parser": {
      "eslint": "8.56.0"
    }
  }

Then I ran npm clean cache --force and then npm install and it worked like a charm for me.

You can manually update eslint-plugin-react-hooks and eslint-plugin-jsx-a11y to 5.0.0 and 6.10.1 respectively which will resolve the peer dep conflict.

We'll make the the versions are updated in Nx 20.1.
