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

3. **Create project structure** (if new):

• Initialize npm project
• Set up TypeScript
• Create folder structure

4. **Install dependencies**:

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

Phase 3: Configuration

5. **Create webflow.json**:

• Set library name
• Configure component glob pattern
• Set up globals if needed

6. **Configure TypeScript**:

• Set up tsconfig.json
• Enable JSX support

Phase 4: Create Starter Files

7. **Create example component**:

• Simple Button component
• Definition file
• Basic styling

8. **Create globals file** (optional):

• For shared styles
• For decorators

Phase 5: Verify Setup

9. **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`

10. **Provide next steps**:

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

Examples

For detailed step-by-step examples, see [references/EXAMPLES.md](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](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:

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