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

Setup & authentication

Installation

# macOS / Linux
curl -fsSL https://vite.plus | bash

# Windows (PowerShell)
irm https://vite.plus/ps1 | iex

Basic project setup

# Interactive project creation
vp create

# Create from a specific template
vp create vite -- --template react-ts

# Monorepo
vp create vite:monorepo

# Migrate existing Vite project
vp migrate

Configuration

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

import { defineConfig } from 'vite-plus';

export default defineConfig({
  // Standard Vite options
  server: {},
  build: {},
  preview: {},

  // Vite+ extensions
  test: {},     // Vitest
  lint: {},     // Oxlint
  fmt: {},      // Oxfmt
  run: {},      // Vite Task
  pack: {},     // tsdown
  staged: {},   // Pre-commit checks
});

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

# Interactive
vp create

# Built-in templates: vite:application, vite:library, vite:monorepo, vite:generator
vp create vite:library --directory my-lib

# Third-party templates
vp create next-app
vp create @tanstack/start

# Pass template-specific options after --
vp create vite -- --template react-ts

Run dev server and build

vp dev          # Start Vite dev server with HMR
vp build        # Production build via Rolldown
vp preview      # Serve production build locally
vp 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

vp check        # Format + lint + type-check in one pass
vp check --fix  # Auto-fix formatting and lint issues

vp lint         # Lint only (Oxlint)
vp lint --fix   # Lint with auto-fix
vp fmt          # Format only (Oxfmt)
vp fmt --check  # Check formatting without writing

Enable type-aware linting in config:

export default defineConfig({
  lint: {
    ignorePatterns: ['dist/**'],
    options: {
      typeAware: true,
      typeCheck: true,
    },
  },
  fmt: {
    singleQuote: true,
  },
});

Run tests

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

export default defineConfig({
  test: {
    include: ['src/**/*.test.ts'],
    coverage: {
      reporter: ['text', 'html'],
    },
  },
});

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

Package a library

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

export default defineConfig({
  pack: {
    dts: true,
    format: ['esm', 'cjs'],
    sourcemap: true,
  },
});

The exe option builds standalone executables for CLI tools.

Execute monorepo tasks

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

export default defineConfig({
  run: {
    tasks: {
      ci: {
        command: 'vp check && vp test && vp build',
        dependsOn: [],
        cache: true,
        env: ['CI', 'NODE_ENV'],
      },
    },
  },
});

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

Manage Node.js versions

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

Error handling

Error	Cause	Resolution
`vp: command not found`	Vite+ not installed or shell not reloaded	Run the install script and restart terminal, or run `vp env print` and add the output to shell config
`vp build` runs custom script instead of Vite build	`package.json` has a `build` script	Use `vp build` for Vite build, `vp run build` for the package.json script
Type-aware lint rules not working	`typeAware` / `typeCheck` not enabled	Set `lint.options.typeAware: true` and `lint.options.typeCheck: true` in config
`vp test` stays in watch mode	Standalone Vitest habit	`vp test` is single-run by default; use `vp test watch` for watch mode
Migration leaves broken imports	Incomplete `vp migrate`	Run `vp install`, then `vp check` to catch remaining import issues
