+# Node.js Version Update - dev-tf Branch
+
+## Changes Made
+
+### 1. Node.js Version Upgrade
+- **Installed Node.js 20.19.6** (via nvm)
+- **Previous version:** Node.js 18.19.1
+- **Reason:** `react-router-dom@7.x` (pulled in by `@ethora/ai-chat-widget` and `@ethora/chat-component`) requires Node >=20.0.0
+
+### 2. Configuration Files Added
+- **`.nvmrc`** - Specifies Node.js 20 for automatic version switching with nvm
+- **`package.json`** - Added `engines` field to enforce Node >=20.0.0 and npm >=10.0.0
+
+### 3. Results
+- ✅ **EBADENGINE warnings resolved** - All Node version mismatch warnings are gone
+- ✅ **Dependencies installed successfully** - 992 packages installed
+- ⚠️ **15 moderate vulnerabilities remain** - These are in transitive dependencies and require breaking changes to fix:
+  - `esbuild` (via `vite`) - Would require upgrading to vite 7.2.7 (breaking change)
+  - `prismjs` (via `react-syntax-highlighter`) - Would require upgrading to react-syntax-highlighter 16.1.0 (breaking change)
+  - `undici` (via `firebase`) - Would require upgrading to firebase 12.6.0 (breaking change)
+
+### 4. Deprecated Packages (Non-Critical)
+These are transitive dependencies and don't affect functionality:
+- `inflight@1.0.6` - Used by older dependencies
+- `glob@7.2.3` - Used by older dependencies
+- `node-domexception@1.0.0` - Used by older dependencies
+- `@mui/base@5.0.0-beta.42` - Replaced by `@base-ui-components/react` (but still works)
+
+## Usage
+
+### Automatic Node Version Switching
+If you have nvm installed, simply run:
+```bash
+cd ethora-app-reactjs
+nvm use  # Automatically uses Node 20 from .nvmrc
+```
+
+### Manual Setup
+If nvm is not installed or you want to use a different Node version manager:
+```bash
+# Install nvm (if not already installed)
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+
+# Load nvm
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
+
+# Install and use Node 20
+nvm install 20
+nvm use 20
+nvm alias default 20
+```
+
+## Remaining Issues
+
+### Vulnerabilities
+The remaining 15 moderate vulnerabilities are in transitive dependencies. To fix them would require:
+1. **Upgrading vite** to 7.x (breaking change - may require code updates)
+2. **Upgrading react-syntax-highlighter** to 16.x (breaking change - may require code updates)
+3. **Upgrading firebase** to 12.x (breaking change - may require code updates)
+
+These can be addressed in future updates when ready to handle breaking changes.
+
+### Deprecated Packages
+The deprecated packages are transitive dependencies and don't pose immediate risks. They will be updated automatically when their parent packages are updated.
+
+## Testing
+
+After switching to Node 20:
+1. Verify Node version: `node --version` (should show v20.x.x)
+2. Reinstall dependencies: `npm install` (should have no EBADENGINE warnings)
+3. Test the app: `npm run dev` (should start without issues)
+
