# migrate-to-rsbuild

A skill that migrates webpack, Vite, Create React App, and Vue CLI projects to Rsbuild. It rewrites build configs and validates dev servers before cleaning up old packages.

## What it does

This skill guides agents through migrating existing build setups to Rsbuild. It detects the source tooling automatically. By inspecting `package.json` scripts and files such as `webpack.config.*`, `vite.config.*`, or `vue.config.*`, the skill identifies whether the project uses webpack, Vite, CRA, or Vue CLI. It then pulls official Rsbuild migration guides to map legacy options to new configurations.

The workflow prioritizes non-destructive updates. The skill never modifies application runtime code unless explicitly told to do so. It establishes a baseline build first, then addresses custom behaviors. Legacy configuration files and dependencies stay untouched until both dev server and production build pass verification.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add rstackjs/agent-skills --skill migrate-to-rsbuild -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/migrate-to-rsbuild/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/migrate-to-rsbuild/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add rstackjs/agent-skills --skill migrate-to-rsbuild -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/migrate-to-rsbuild/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add rstackjs/agent-skills --skill migrate-to-rsbuild -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/migrate-to-rsbuild/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install rstackjs/agent-skills migrate-to-rsbuild
```

2. **Manually: put the files in place**
- File: `.github/skills/migrate-to-rsbuild/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add rstackjs/agent-skills --skill migrate-to-rsbuild -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/rstackjs/agent-skills --path skills/migrate-to-rsbuild
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/migrate-to-rsbuild/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add rstackjs/agent-skills --skill migrate-to-rsbuild -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/rstackjs/agent-skills/tree/HEAD/skills/migrate-to-rsbuild/SKILL.md

## When to use it
- migrate Create React App or CRACO setups to Rsbuild
- switch webpack or Vite builds to Rsbuild without manual config mapping
- port Vue CLI applications to Rsbuild
- test dev servers and production builds before removing legacy dependencies

## Example prompts
- Migrate this project from webpack to Rsbuild and test the build
- Switch our Create React App setup to Rsbuild without modifying application code
- Help me move from Vite to Rsbuild and delete legacy configs once dev server runs cleanly

# Migrate to Rsbuild

## Goal

Migrate webpack, Vite, create-react-app (CRA/CRACO), or Vue CLI projects to Rsbuild with minimal behavior changes and clear verification.

## Supported source frameworks

- webpack
- Vite
- CRA / CRACO
- Vue CLI

## Migration principles (must follow)

1. **Official guide first**: treat Rsbuild migration docs as source of truth.
2. **Smallest-change-first**: complete baseline migration first, then migrate custom behavior.
3. **Do not change business logic**: avoid touching app runtime code unless user explicitly asks.
4. **Validate before cleanup**: keep old tool dependencies/config temporarily if needed; remove only after Rsbuild is green.

## Workflow

1. **Detect source framework**
   - Check `package.json` dependencies/scripts and config files:
     - webpack: `webpack.config.*`
     - Vite: `vite.config.*`
     - CRA/CRACO: `react-scripts`, `@craco/craco`, `craco.config.*`
     - Vue CLI: `@vue/cli-service`, `vue.config.*`

2. **Apply framework-specific deltas**
   - webpack: `references/webpack.md`
   - Vite: `references/vite.md`
   - CRA/CRACO: `references/cra.md`
   - Vue CLI: `references/vue-cli.md`

3. **Validate behavior**
   - Run dev server to verify the project starts without errors.
   - Run build command to verify the project builds successfully.
   - If issues remain, compare the old project configuration with the migration guide and complete any missing mappings.

4. **Cleanup and summarize**
   - Remove obsolete dependencies/config only after validation passes.
   - Summarize changed files and any remaining manual follow-ups.
