Web Artifacts Builder

To build powerful frontend claude.ai artifacts, follow these steps:

Initialize the frontend repo
Develop your artifact by editing the generated code
Bundle all code into a single HTML file
Display artifact to user
(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

Create a new React 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

Step 2: Develop Your Artifact

Build the artifact by editing the generated files.

Step 3: Bundle to Single HTML File

Bundle the React app into a single HTML artifact. This creates bundle.html - a self-contained artifact with all JavaScript, CSS, and dependencies inlined.

Requirements: Your project must have an index.html in the root directory.

What bundling does:

Installs bundling dependencies (parcel, @parcel/config-default, parcel-resolver-tspaths, html-inline)
Creates .parcelrc config with path alias support
Builds with Parcel (no source maps)
Inlines all assets into single HTML using html-inline

Step 4: Share Artifact with User

Share the bundled HTML file in conversation with the user so they can view it as an artifact.

Step 5: Testing/Visualizing the Artifact (Optional)

Use available tools (including other Skills or built-in tools like Playwright or Puppeteer) to test/visualize the artifact. Avoid testing the artifact upfront as it adds latency between the request and when the finished artifact can be seen.
