webflow-code-component:local-dev-setup

A setup guide for starting a Webflow Code Components project, which lets developers build reusable React components for Webflow. It creates the project structure, installs dependencies, and configures the development environment.

In plain words
What is it for?
Use it when creating a new Code Components project or preparing an existing React-based project for Webflow component development.
Why use it?
It removes the repetitive first-time work of preparing React, TypeScript, Webflow tools, and project configuration. It can also add Code Components to an existing React, Next.js, or Vite project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

webflow-code-component:local-dev-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
