npm install fails with ERESOLVE peer dependency conflict on react-dom/streamdown

name: Bug report about: Create a report to help us improve title: 'npm install fails with ERESOLVE peer dependency conflict on react-dom/streamdown' labels: bug assignees: ''

Describe the bug Running npx next-forge@latest init fails during the Installing dependencies step when using npm due to an ERESOLVE peer dependency conflict in packages/ai.

In packages/ai/package.json, streamdown requires peer react-dom@"^18.0.0 || ^19.0.0". Because react-dom is missing from packages/ai's dependencies (only react: "19.2.4" is declared), npm resolves the latest matching react-dom (e.g. 19.2.8), which requires peer react@"^19.2.8". This conflicts with the pinned react@"19.2.4" across the workspace.

next-forge version I am using version 6.0.2 (latest).

To Reproduce Steps to reproduce the behavior:

1. Run npx next-forge@latest init
2. Enter project name (e.g. my-project)
3. Select npm as the package manager (or let npm be auto-detected)
4. See error:

npm error code ERESOLVE

npm error   node_modules/streamdown
npm error     streamdown@"^2.4.0" from @repo/[[email protected]](mailto:[email protected])

Expected behavior npm install should complete successfully without dependency resolution errors during project initialization.

Suggested Fix Add "react-dom": "19.2.4" to dependencies in packages/ai/package.json to keep react and react-dom aligned:

{
  "dependencies": {
    "react": "19.2.4",
    "react-dom": "19.2.4",
    "streamdown": "^2.4.0"
  }
}
