+# Automatic Package Installation (package-auto-install)
+
+Automatically detects and runs npm/yarn/pnpm install in non-interactive mode after container creation.
+
+## Features
+
+- **Automatic detection**: Detects package manager based on lockfile (pnpm-lock.yaml, yarn.lock, package-lock.json)
+- **Corepack support**: Automatically installs and enables corepack if `packageManager` field is found in package.json (required for Node 24+)
+- **Non-interactive mode**: Sets `CI=true` to avoid prompts (e.g., pnpm won't ask to delete node_modules)
+- **Smart command selection**: Uses `npm ci`, `pnpm install --frozen-lockfile`, or `yarn install --immutable` when lockfiles exist
+- **Flexible configuration**: Override package manager, command, and working directory
+- **Skip if exists**: Optionally skip installation if node_modules already exists
+
+## Usage
+
+### Basic Usage
+
+Add this feature to your `devcontainer.json`:
+
+```json
+{
+    "features": {
+        "ghcr.io/helpers4/devcontainer/package-auto-install:1": {}
+    }
+}
+```
+
+This will:
+1. Detect the package manager from lockfile
+2. Run the appropriate install command automatically
+3. Set `CI=true` to prevent interactive prompts
+
+### Remove Manual postCreateCommand
+
+If you have this in your devcontainer.json, you can now remove it:
+
+```json
+{
+    "postCreateCommand": "CI=true pnpm install"  // ❌ Not needed anymore
+}
+```
+
+## Options
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `command` | string | `auto` | Installation command: `install`, `ci`, or `auto` to detect |
+| `packageManager` | string | `auto` | Package manager: `npm`, `yarn`, `pnpm`, or `auto` to detect |
+| `workingDirectory` | string | `/workspaces/${localWorkspaceFolderBasename}` | Directory where to run install |
+| `skipIfNodeModulesExists` | boolean | `false` | Skip if node_modules exists |
+| `additionalArgs` | string | `""` | Additional arguments for install command |
+
+## Examples
+
+### Force specific package manager
+
+```json
+{
+    "features": {
+        "ghcr.io/helpers4/devcontainer/package-auto-install:1": {
+            "packageManager": "pnpm"
+        }
+    }
+}
+```
+
+### Use npm ci explicitly
+
+```json
+{
+    "features": {
+        "ghcr.io/helpers4/devcontainer/package-auto-install:1": {
+            "packageManager": "npm",
+            "command": "ci"
+        }
+    }
+}
+```
+
+### Skip if node_modules exists (useful for rebuilds)
+
+```json
+{
+    "features": {
+        "ghcr.io/helpers4/devcontainer/package-auto-install:1": {
+            "skipIfNodeModulesExists": true
+        }
+    }
+}
+```
+
+### Pass additional arguments
+
+```json
+{
+    "features": {
+        "ghcr.io/helpers4/devcontainer/package-auto-install:1": {
+            "additionalArgs": "--ignore-scripts"
+        }
+    }
+}
+```
+
+### Custom working directory
+
+```json
+{
+    "features": {
+        "ghcr.io/helpers4/devcontainer/package-auto-install:1": {
+            "workingDirectory": "/workspace/frontend"
+        }
+    }
+}
+```
+
+## How It Works
+Corepack Support (Node 24+)
+
+If your `package.json` contains a `packageManager` field (e.g., `"packageManager": "pnpm@9.0.0"`):
+
+1. The feature checks if corepack is available
+2. If not, it installs corepack globally with `npm install -g corepack`
+3. Enables corepack with `corepack enable`
+4. Corepack then automatically installs and uses the exact package manager version specified
+
+This is particularly important for Node 24+ where corepack is no longer included by default.
+
+### 
+### Package Manager Detection
+
+The feature detects the package manager in this order:
+
+1. **From `packageManager` field in package.json** (highest priority)
+   - Example: `"packageManager": "pnpm@9.0.0"` → uses **pnpm**
+   - This is the most reliable and modern approach
+2. **From lockfiles**:
+   - `pnpm-lock.yaml` → uses **pnpm**
+   - `yarn.lock` → uses **yarn**
+   - `package-lock.json` → uses **npm**
+3. **Default**: Falls back to **npm** if nothing is detected
+
+### Command Selection (when `command: "auto"`)
+
+For each package manager:
+
+- **npm**: Uses `npm ci` if package-lock.json exists, otherwise `npm install`
+- **pnpm**: Uses `pnpm install --frozen-lockfile` if pnpm-lock.yaml exists, otherwise `pnpm install`
+- **yarn**: 
+  - Yarn 2+: Uses `yarn install --immutable` if yarn.lock exists
+  - Yarn 1.x: Uses `yarn install --frozen-lockfile` if yarn.lock exists
+
+### CI Mode
+
+The feature sets `CI=true` environment variable, which:
+
+- **pnpm**: Automatically removes old node_modules without prompting
+- **npm**: Enables strict mode in `npm ci`
+- **yarn**: Enables immutable installs
+
+## Execution Order
+
+The feature uses `installsAfter` to ensure it runs after:
+- `ghcr.io/devcontainers/features/common-utils`
+- `ghcr.io/devcontainers/features/node`
+
+The actual package installation runs in `postCreateCommand`, which is the last lifecycle hook after all features are installed.
+
+## Troubleshooting
+
+### Installation not running
+
+Check that:
+- `package.json` exists in the working directory
+- The package manager is installed (use node feature or appropriate base image)
+
+### Wrong package manager detected
+
+Force the package manager explicitly:
+
+```json
+{
+    "features": {
+        "ghcr.io/helpers4/devcontainer/package-auto-install:1": {
+            "packageManager": "pnpm"
+        }
+    }
+}
+```
+
+### Installation fails
+
+Check the container logs during creation. The feature will show the exact command being run and any errors.
+
+### Need to debug
+
+You can manually run the installation script:
+
+```bash
+/usr/local/bin/devcontainer-package-install
+```
+
+## Future Enhancements
+
+Planned features:
+- Support for monorepos (multiple package.json locations)
+- Custom post-install scripts
+- Conditional installation based on file changes
+- Cache optimization

+# Vite+ Development Environment (vite-plus)
+
+Complete Vite+ toolchain setup with VS Code extensions, Oxc formatter/linter, Vitest, and optimized configuration for the unified web development workflow.
+
+## Features
+
+- **VS Code Extensions**: Oxc and Vitest extensions pre-configured
+- **Vite CLI**: Optional global Vite installation for quick project scaffolding
+- **Vitest CLI**: Optional global Vitest installation for running tests
+- **Oxc Integration**: Blazing fast linting and formatting (100x faster than ESLint)
+- **Vitest Support**: Test explorer and optimal configuration
+- **Smart Defaults**: Editor configured for Vite+ best practices
+- **Project Helper**: Includes `vite-plus-init` command for setup guidance
+
+## What is Vite+?
+
+Vite+ is the unified toolchain for web development, combining:
+
+- **Vite** - Lightning-fast dev server and build tool
+- **Vitest** - Fast unit test framework
+- **Oxc** - Ultra-fast linter and formatter (Rust-based)
+- **Rolldown** - Faster bundler
+- All-in-one CLI for dev, test, lint, format, and more
+
+Built by the creators of Vite, Vitest, and Oxc for enterprise-scale productivity.
+
+## Usage
+
+### Basic Setup
+
+Add this feature to your `devcontainer.json`:
+
+```json
+{
+    "features": {
+        "ghcr.io/helpers4/devcontainer/vite-plus:1": {}
+    }
+}
+```
+
+This will:
+1. Install Vite, Vitest, and Oxc CLIs globally
+2. Install Oxc and Vitest VS Code extensions
+3. Configure Oxc as the default formatter
+4. Enable format-on-save and auto-fix
+5. Set up Vitest test explorer
+
+### With Global CLIs (default)
+
+```json
+{
+    "features": {
+        "ghcr.io/helpers4/devcontainer/viteplus:1": {
+            "installVite": true,
+            "installVitest": true,
+            "installOxc": true
+        }
+    }
+}
+```
+
+This allows you to run `vite`, `vitest`, and `oxc` commands globally without npx.
+
+### With Vite+ Unified CLI (Early Access)
+
+```json
+{
+    "features": {
+        "ghcr.io/helpers4/devcontainer/vite-plus:1": {
+            "installVite": true,
+            "installVitest": true,
+            "installVitePlus": true,
+            "installOxc": true
+        }
+    }
+}
+```
+
+**Note**: Vite+ is currently in early access. Register at [viteplus.dev](https://viteplus.dev/). When available, this will install the unified `vite+` CLI.
+
+## Options
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `installVite` | boolean | `true` | Install Vite CLI globally |
+| `installVitest` | boolean | `true` | Install Vitest CLI globally |
+| `installVitePlus` | boolean | `false` | Install Vite+ unified CLI globally (early access) |
+| `installOxc` | boolean | `true` | Install Oxc CLI globally |
+| `enableExperimentalFormatter` | boolean | `true` | Enable experimental Oxc formatter features |
+
+## VS Code Extensions Included
+
+### Oxc (oxc.oxc-vscode)
+- Ultra-fast linting (up to 100x faster than ESLint)
+- Prettier-compatible formatting
+- ESLint rule compatibility (600+ rules)
+- Type-aware linting support
+
+### Vitest Explorer (vitest.explorer)
+- Test discovery and navigation
+- Run/debug tests from UI
+- Watch mode integration
+- Coverage visualization
+
+## VS Code Configuration Applied
+
+```json
+{
+  "oxc.enable": true,
+  "oxc.lint.enable": true,
+  "oxc.fmt.enable": true,
+  "oxc.fmt.experimental": true,
+  "editor.defaultFormatter": "oxc.oxc-vscode",
+  "editor.formatOnSave": true,
+  "editor.codeActionsOnSave": {
+    "source.fixAll.oxc": "explicit"
+  },
+  "vitest.enable": true,
+  "vitest.commandLine": "npx vitest"  // Uses local project version if available
+}
+```
+
+**Note**: Even though Vitest is installed globally, `npx vitest` ensures the test runner uses the project's local version specified in `package.json`, maintaining consistency across the team.
+
+## Project Setup Helper
+
+After the container is created, run:
+
+```bash
+vite-plus-init
+```
+
+This displays:
+- Recommended dependencies for your project type
+- Example configuration files
+- Setup instructions for React, Vue, or other frameworks
+
+## Typical Project Setup
+
+### 1. Install Dependencies
+
+```bash
+# Core Vite+ toolchain
+npm install -D vite vitest
+
+# Oxc tools (if not using unified Vite+ CLI)
+npm install -D oxc-linter oxc-formatter
+
+# For React
+npm install -D @vitejs/plugin-react
+
+# For Vue
+npm install -D @vitejs/plugin-vue
+```
+
+### 2. Create vite.config.ts
+
+```typescript
+import { defineConfig } from 'vite'
+import react from '@vitejs/plugin-react'
+
+export default defineConfig({
+  plugins: [react()],
+  test: {
+    globals: true,
+    environment: 'happy-dom',
+  },
+})
+```
+
+### 3. Create oxc.config.json
+
+```json
+{
+  "lint": {
+    "rules": {
+      "no-unused-vars": "error",
+      "no-console": "warn"
+    }
+  },
+  "format": {
+    "indentWidth": 2,
+    "lineWidth": 100
+  }
+}
+```
+
+### 4. Update package.json scripts
+
+```json
+{
+  "scripts": {
+    "dev": "vite",
+    "build": "vite build",
+    "preview": "vite preview",
+    "test": "vitest",
+    "test:ui": "vitest --ui",
+    "lint": "oxc lint .",
+    "format": "oxc fmt ."
+  }
+}
+```
+
+## Works Great With
+
+Combine with other features for a complete development environment:
+
+```json
+{
+  "features": {
+    "ghcr.io/helpers4/devcontainer/vite-plus:1": {},
+    "ghcr.io/helpers4/devcontainer/package-auto-install:1": {},
+    "ghcr.io/helpers4/devcontainer/local-mounts:1": {},
+    "ghcr.io/helpers4/devcontainer/shell-history-per-project:1": {},
+    "ghcr.io/helpers4/devcontainer/git-absorb:1": {}
+  }
+}
+```
+
+## Supported Frameworks
+
+Vite+ works with all Vite-compatible frameworks:
+
+- ⚛️ **React** - Via `@vitejs/plugin-react`
+- 🟢 **Vue** - Via `@vitejs/plugin-vue`
+- 🔶 **Svelte** - Via `@sveltejs/vite-plugin-svelte`
+- 🔷 **Solid** - Via `vite-plugin-solid`
+- 🅰️ **Angular** - Via Angular's Vite integration
+- And 20+ more frameworks
+
+## Performance Benefits
+
+- **40x faster builds** than webpack
+- **100x faster linting** than ESLint
+- **Instant HMR** for all file types
+- **Native speed formatting** with Oxc
+- **Fast unit tests** with Vitest
+
+## Troubleshooting
+
+### Oxc not formatting
+
+Check that `oxc.oxc-vscode` extension is enabled:
+```bash
+code --list-extensions | grep oxc
+```
+
+### Vitest not discovering tests
+
+Ensure your `vite.config.ts` includes test configuration:
+```typescript
+export default defineConfig({
+  test: {
+    include: ['**/*.{test,spec}.{js,mjs,cjs,ts,mts,cts,jsx,tsx}']
+  }
+})
+```
+
+### Global CLI not available
+
+If `oxc` or `vite` commands aren't found, ensure the feature installed with:
+```json
+{
+  "features": {
+    "ghcr.io/helpers4/devcontainer/viteplus:1": {
+      "installOxc": true
+    }
+  }
+}
+```
+vite`, `vitest`, or `oxc` commands aren't found, ensure the feature installed with:
+```json
+{
+  "features": {
+    "ghcr.io/helpers4/devcontainer/vite-plus:1": {
+      "installVite": true,
+      "installVitest": true,/r/nGWebL
