Webflow Code Component:local Dev Setup Agent Skill

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

• Check if project exists:
• Is there an existing package.json?
• Is there an existing webflow.json?
• What's the current project structure?

• Determine setup type:
• New project from scratch
• Add to existing React project
• Add to existing Next.js/Vite project

Phase 2: Project Initialization

• Create project structure (if new):
• Initialize npm project
• Set up TypeScript
• Create folder structure

• Install dependencies:
• Core: React, TypeScript
• Webflow: CLI, data-types, react utils
• Optional: Styling libraries

Phase 3: Configuration

• Create webflow.json:
• Set library name
• Configure component glob pattern
• Set up globals if needed

• Configure TypeScript:
• Set up tsconfig.json
• Enable JSX support

Phase 4: Create Starter Files

• Create example component:
• Simple Button component
• Definition file
• Basic styling

• Create globals file (optional):
• For shared styles
• For decorators

Phase 5: Verify Setup

• 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

• How to create more components
• How to deploy
• Development workflow

Examples

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

Available examples:

• New Project from Scratch - Complete setup with React, TypeScript, and CSS Modules
• Add to Existing React Project - Integrate code components into an existing codebase
• 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:

| Check | How to Verify |

|-------|---------------|

| webflow.json exists in project root | cat webflow.json |

| Dependencies installed | npm list @webflow/webflow-cli |

| Bundle compiles without errors | npx webflow library bundle --public-path http://localhost:4000/ |

| At least one component found | Check bundle output for "Found N component(s)" |

Guidelines

Minimum Requirements

Every code components project needs:

• package.json with dependencies
• webflow.json with library config
• tsconfig.json (for TypeScript)
• At least one .webflow.tsx file

Development Workflow

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