Web Artifacts Builder

To build powerful frontend Codex artifacts, follow these steps:

1. Initialize the frontend repo using scripts/init-artifact.sh
2. Develop your artifact by editing the generated code
3. Bundle all code into a single HTML file using scripts/bundle-artifact.sh
4. Display artifact to user
5. (Optional) Test the artifact

Stack: React 18 + TypeScript + Vite + Parcel (bundling) + Tailwind CSS + shadcn/ui

Design & Style Guidelines

VERY IMPORTANT: To avoid what is often referred to as "AI slop", avoid using excessive centered layouts, purple gradients, uniform rounded corners, and Inter font.

Quick Start

Step 1: Initialize Project

Run the initialization script to create a new React project:

bash scripts/init-artifact.sh <project-name>
cd <project-name>

This creates a fully configured project with:

• ✅ React + TypeScript (via Vite)
• ✅ Tailwind CSS 3.4.1 with shadcn/ui theming system
• ✅ Path aliases (@/) configured
• ✅ 40+ shadcn/ui components pre-installed
• ✅ All Radix UI dependencies included
• ✅ Parcel configured for bundling (via .parcelrc)
• ✅ Node 18+ compatibility (auto-detects and pins Vite version)

Step 2: Develop Your Artifact

To build the artifact, edit the generated files. See Common Development Tasks below for guidance.

Step 3: Bundle to Single HTML File

ReactコンポーネントをCodexで共有できる単一HTMLにまとめるには、プロジェクト直下で次を実行します（例: ./scripts/bundle-artifact.sh）:

bash scripts/bundle-artifact.sh

これで bundle.html が生成され、JS/CSS/アセットがすべてインライン化された1ファイルになります。bundle.html を Codex チャットに添付すれば、そのまま実行可能なアーティファクトとして共有できます。

Requirements: プロジェクト直下に index.html があること。

What the script does:

• bundling依存 (parcel, @parcel/config-default, parcel-resolver-tspaths, html-inline) を導入
• .parcelrc を生成してパスエイリアス対応
• Parcelでビルド（source mapなし）
• html-inline で dist/index.html を1ファイル化 (bundle.html 出力)

Step 4: Share Artifact with User

生成された bundle.html を Codex で提示・添付すれば、追加のビルドや依存インストールなしでそのまま開けます。

Step 5: Testing/Visualizing the Artifact (Optional)

Note: This is a completely optional step. Only perform if necessary or requested.

To test/visualize the artifact, use available tools (including other Skills or built-in tools like Playwright or Puppeteer). In general, avoid testing the artifact upfront as it adds latency between the request and when the finished artifact can be seen. Test later, after presenting the artifact, if requested or if issues arise.
