Artifacts Builder
To build powerful frontend claude.ai artifacts, follow these steps:
Initialize the frontend repo using scripts/init-artifact.sh
Develop your artifact by editing the generated code
Bundle all code into a single HTML file using scripts/bundle-artifact.sh
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.
