# Configure Vite Projects Faster

Vite projects often need precise configuration across dev, build, SSR, and plugins. This skill gives Claude, Codex, and Claude Code focused Vite reference guidance.

## Install

```bash
npx skillstore add antfu/vite

## Capabilities

- Explains Vite config files, defineConfig, modes, aliases, and environment loading.
- Guides common CLI workflows for dev servers, production builds, and preview commands.
- Covers plugin usage, plugin ordering, virtual modules, and hook behavior.
- Supports build topics including SSR, library mode, assets, CSS, and multi-page apps.
- Provides performance guidance for dependency pre-bundling, caching, and build optimization.

## Use Cases

- Set Up A New Vite App: Choose config patterns, scripts, aliases, and env modes for a clean project start.
- Prepare Production Builds: Tune assets, targets, minification, chunking, manifests, and preview workflows before release.
- Extend Vite With Plugins: Understand plugin hooks, ordering, virtual modules, and integration points for custom tooling.

## Prompt Templates

### Create Basic Config

```
Help me create a basic Vite configuration for my app. Include scripts, aliases, and safe environment variable guidance.
```

### Fix Dev Server Setup

```
Review my Vite dev server needs and recommend settings for host, port, CORS, HMR, and dependency optimization.
```

### Plan Production Build

```
Design a Vite production build plan for assets, CSS splitting, sourcemaps, targets, manifests, and preview validation.
```

### Design Advanced Integration

```
Help me design a Vite SSR or plugin integration. Explain hooks, server behavior, build outputs, and security considerations.
```

## Limitations

- It is a reference skill, not a live Vite project analyzer.
- It does not install packages or run builds by itself.
- It is based on Vite 6.x documentation generated on 2026-01-28.
- Framework-specific behavior still depends on each project and plugin version.

## Best Practices

- Keep secrets out of VITE-prefixed variables because they can reach client bundles.
- Use official plugin patterns before adding custom build or transform logic.
- Validate production output with vite preview before deploying build artifacts.

## Anti Patterns

- Do not expose all environment variables through an empty env prefix.
- Do not add custom plugins when a maintained Vite plugin already solves the task.
- Do not treat development server options as production server hardening.

## Security Audit

- - Safe to publish: true
- - Audited at: 2026-06-28T09:48:49.111\+00:00
- - Summary: Static analysis reported many command, network, filesystem, and environment alerts, but reviewed locations are markdown documentation examples for Vite. No prompt injection, malicious intent, credential exfiltration, or executable skill code was found; residual risk is low because the references discuss environment files and development server settings.
