Vite+

Vite+ is the unified toolchain for web development by VoidZero. It consolidates the dev server (Vite), bundler (Rolldown), test runner (Vitest), linter (Oxlint), formatter (Oxfmt), task runner (Vite Task), and library packager (tsdown) into a single CLI called vp. It also manages Node.js versions and package managers globally, replacing the need for nvm, fnm, or Corepack.

When to use this skill

Trigger this skill when the user:

• Wants to scaffold a new project or monorepo with vp create
• Needs to migrate an existing Vite/Vitest project to Vite+
• Asks about vp dev, vp build, vp test, vp lint, vp fmt, or vp check
• Configures vite.config.ts with lint, fmt, test, run, pack, or staged blocks
• Runs monorepo tasks with vp run -r or workspace filtering
• Packages a library with vp pack (tsdown integration)
• Manages Node.js versions with vp env
• References the vp or vpx CLI commands

Do NOT trigger this skill for:

• Plain Vite (without Vite+) configuration - use standard Vite docs instead
• Vitest standalone usage without Vite+ wrapping

Configuration

All tool configuration lives in a single vite.config.ts:

typescript
1import { defineConfig } from 'vite-plus';
2
3export default defineConfig({
4  // Standard Vite options
5  server: {},
6  build: {},
7  preview: {},
8
9  // Vite+ extensions
10  test: {},     // Vitest
11  lint: {},     // Oxlint
12  fmt: {},      // Oxfmt
13  run: {},      // Vite Task
14  pack: {},     // tsdown
15  staged: {},   // Pre-commit checks
16});

Core concepts

Vite+ ships as two pieces: vp (global CLI) and vite-plus (local project package). The global CLI handles runtime management and project scaffolding. The local package provides the defineConfig function and all tool integrations.

Unified config model - instead of separate config files for each tool (vitest.config.ts, .oxlintrc.json, .prettierrc), everything consolidates into vite.config.ts. Do not create separate config files for Oxlint, Oxfmt, Vitest, or tsdown when using Vite+.

Command surface - vp wraps each integrated tool behind a consistent CLI. vp dev and vp build run standard Vite. vp test runs Vitest (single-run by default, unlike standalone Vitest which defaults to watch). vp check runs fmt + lint + typecheck in one pass using Oxfmt, Oxlint, and tsgolint.

Environment management - Vite+ manages Node.js installations in ~/.vite-plus. In managed mode (default), shims always use the Vite+-managed Node.js. Use vp env off to switch to system-first mode. Pin project versions with vp env pin which writes a .node-version file.

Common tasks

Scaffold a new project

bash
1# Interactive
2vp create
3
4# Built-in templates: vite:application, vite:library, vite:monorepo, vite:generator
5vp create vite:library --directory my-lib
6
7# Third-party templates
8vp create next-app
9vp create @tanstack/start
10
11# Pass template-specific options after --
12vp create vite -- --template react-ts

Run dev server and build

bash
1vp dev          # Start Vite dev server with HMR
2vp build        # Production build via Rolldown
3vp preview      # Serve production build locally
4vp build --watch --sourcemap  # Watch mode with source maps

vp build always runs the built-in Vite build. If your package.json has a custom build script, use vp run build instead.

Lint, format, and type-check

bash
1vp check        # Format + lint + type-check in one pass
2vp check --fix  # Auto-fix formatting and lint issues
3
4vp lint         # Lint only (Oxlint)
5vp lint --fix   # Lint with auto-fix
6vp fmt          # Format only (Oxfmt)
7vp fmt --check  # Check formatting without writing

Enable type-aware linting in config:

typescript
1export default defineConfig({
2  lint: {
3    ignorePatterns: ['dist/**'],
4    options: {
5      typeAware: true,
6      typeCheck: true,
7    },
8  },
9  fmt: {
10    singleQuote: true,
11  },
12});

Run tests

bash
1vp test              # Single test run (NOT watch mode by default)
2vp test watch        # Enter watch mode
3vp test run --coverage  # With coverage report

typescript
1export default defineConfig({
2  test: {
3    include: ['src/**/*.test.ts'],
4    coverage: {
5      reporter: ['text', 'html'],
6    },
7  },
8});

Unlike standalone Vitest, vp test defaults to single-run mode.

Package a library

bash
1vp pack                        # Build library
2vp pack src/index.ts --dts     # Specific entry with TypeScript declarations
3vp pack --watch                # Watch mode

typescript
1export default defineConfig({
2  pack: {
3    dts: true,
4    format: ['esm', 'cjs'],
5    sourcemap: true,
6  },
7});

The exe option builds standalone executables for CLI tools.

Execute monorepo tasks

bash
1vp run build             # Run build script in current package
2vp run build -r          # Run across all workspace packages (dependency order)
3vp run build -t          # Run in package + all its dependencies
4vp run build --filter "my-app"  # Filter by package name
5vp run build -v          # Verbose with cache stats

typescript
1export default defineConfig({
2  run: {
3    tasks: {
4      ci: {
5        command: 'vp check && vp test && vp build',
6        dependsOn: [],
7        cache: true,
8        env: ['CI', 'NODE_ENV'],
9      },
10    },
11  },
12});

Tasks in vite.config.ts are cached by default. Package.json scripts are not - use --cache to enable.

Manage Node.js versions

bash
1vp env pin 22            # Pin project to Node 22 (.node-version)
2vp env default 22        # Set global default
3vp env install 22        # Install a Node.js version
4vp env current           # Show resolved environment
5vp env on / vp env off   # Toggle managed vs system-first mode
6vp env doctor            # Run diagnostics

Error handling

Gotchas

1. vp build and vp run build are different commands - vp build always invokes the built-in Vite build regardless of package.json scripts. vp run build executes the build script in package.json. If your project has a custom build script that wraps Vite with additional steps, use vp run build. Using vp build will skip those steps silently.

2. Separate config files for Vitest/Oxlint/Oxfmt will conflict with Vite+ config - Vite+ reads all tool configuration exclusively from vite.config.ts. If a vitest.config.ts, .oxlintrc.json, or .prettierrc exists alongside it, the behavior is undefined and tools may use conflicting settings. Remove separate configs entirely when migrating to Vite+.

3. vp test is single-run by default, unlike standalone Vitest - Developers migrating from standalone Vitest expect watch mode. Running vp test in CI is correct; running it locally for development requires vp test watch. This is the opposite of Vitest's default behavior.

4. vp migrate does not update import paths for tool-specific APIs - The migration command handles config consolidation but does not rewrite imports like import { defineConfig } from 'vitest/config' to import { defineConfig } from 'vite-plus'. Remaining broken imports will surface as type errors after migration; run vp check to find them.

5. Node.js managed mode intercepts all node calls, including CI scripts - In managed mode (default), the Vite+ shim is at the front of PATH. CI environments with pre-installed Node.js may behave unexpectedly. Run vp env doctor to verify the resolved environment and use vp env off to switch to system-first mode in CI if needed.

For detailed configuration options and advanced usage, read these files:

• references/config.md - full configuration reference for all vite.config.ts blocks (lint, fmt, test, run, pack, staged)
• references/env-management.md - Node.js version management and runtime modes
• references/task-runner.md - monorepo task execution, caching, and dependency ordering

Only load a references file if the current task requires it - they consume context.
