Local Dev Setup

Set up a new Webflow Code Components project from scratch.

When to Use This Skill

Use when:

• Starting a brand new code components project
• User asks to set up, initialize, or create a new project
• Adding code components to an existing React project
• Setting up the development environment for the first time

Do NOT use when:

• Project already exists and is configured (just answer questions directly)
• Creating individual components (use component-scaffold instead)
• Deploying components (use deploy-guide instead)

Instructions

Phase 1: Assess Current State

1. Check if project exists:
   • Is there an existing package.json?
   • Is there an existing webflow.json?
   • What’s the current project structure?
2. Determine setup type:
   • New project from scratch
   • Add to existing React project
   • Add to existing Next.js/Vite project

Phase 2: Project Initialization

1. Create project structure (if new):
   • Initialize npm project
   • Set up TypeScript
   • Create folder structure
2. Install dependencies:
   • Core: React, TypeScript
   • Webflow: CLI, data-types, react utils
   • Optional: Styling libraries

Phase 3: Configuration

1. Create webflow.json:
   • Set library name
   • Configure component glob pattern
   • Set up globals if needed
2. Configure TypeScript:
   • Set up tsconfig.json
   • Enable JSX support

Phase 4: Create Starter Files

1. Create example component:
   • Simple Button component
   • Definition file
   • Basic styling
2. Create globals file (optional):
   • For shared styles
   • For decorators

Phase 5: Verify Setup

1. Verify bundle compiles:
   • Run npx webflow library bundle --public-path http://localhost:4000/ to catch build errors locally
   • This verifies your components, imports, and configuration are correct
   • Full testing in the Webflow Designer requires deploying with npx webflow library share
2. Provide next steps:
   • How to create more components
   • How to deploy
   • Development workflow

Examples

For detailed step-by-step examples, see references/EXAMPLES.md.

Available examples:

1. New Project from Scratch - Complete setup with React, TypeScript, and CSS Modules
2. Add to Existing React Project - Integrate code components into an existing codebase
3. With Tailwind CSS - Setup with Tailwind CSS support

Quick Start (New Project):

# 1. Create project
mkdir my-webflow-components && cd my-webflow-components
npm init -y

# 2. Install dependencies
npm install react react-dom
npm install -D typescript @types/react @types/react-dom
npm install -D @webflow/webflow-cli @webflow/data-types @webflow/react

# 3. Create webflow.json
echo '{"library":{"name":"My Library","components":["./src/**/*.webflow.tsx"]}}' > webflow.json

# 4. Create component directory
mkdir -p src/components/Button

Then create your component files (.tsx, .webflow.tsx, .module.css). See Example 1 in references/EXAMPLES.md for complete file contents including component, definition, and CSS files.

Deploy with:

npx webflow library share

Validation

After setup, verify the project is correctly configured:

Guidelines

Minimum Requirements

Every code components project needs:

1. package.json with dependencies
2. webflow.json with library config
3. tsconfig.json (for TypeScript)
4. At least one .webflow.tsx file

Development Workflow

1. Create component: Use component-scaffold skill
2. Develop locally: Run React project to iterate (e.g., npm run dev)
3. Validate: Use pre-deploy-check skill
4. Deploy: Use deploy-guide skill or run npx webflow library share
5. Test in Webflow: Add component to page in Designer
