# Cloudflare Gen

Cloudflare Workers are powerful but wrangler.toml syntax is its own thing. This tool generates Worker code and configuration from plain English. Edge functions, KV storage, R2 buckets. All set up correctly.

**One command. Zero config. Just works.**

## Quick Start

```bash
npx ai-cloudflare "API proxy with rate limiting"
```

## What It Does

- Generates wrangler.toml configuration
- Creates Worker TypeScript/JavaScript code
- Sets up KV namespaces and R2 bindings
- Includes proper routing and middleware
- Handles environment variables and secrets

## Usage Examples

```bash
# Simple Worker
npx ai-cloudflare "redirect based on country"

# API with storage
npx ai-cloudflare "REST API with KV storage for user preferences"

# Edge caching
npx ai-cloudflare "cache API responses at the edge for 1 hour"

# Auth middleware
npx ai-cloudflare "JWT validation middleware for API routes"
```

## Best Practices

- **Keep Workers small** - Edge has size limits
- **Use KV for reads** - KV is fast for reads, slow for writes
- **Handle errors** - Edge errors are hard to debug, be explicit
- **Test locally** - wrangler dev before deploying

## When to Use This

- Building serverless functions on Cloudflare
- Need edge computing for latency-sensitive features
- Setting up Cloudflare Pages with Workers
- Learning Workers and want working examples

## Part of the LXGIC Dev Toolkit

This is one of 110+ free developer tools built by LXGIC Studios. No paywalls, no sign-ups, no API keys on free tiers. Just tools that work.

## Requirements

No install needed. Just run with npx. Node.js 18+ recommended. Requires OPENAI_API_KEY environment variable.

```bash
export OPENAI_API_KEY=sk-...
npx ai-cloudflare --help
```

## How It Works

Takes your description and generates both the Worker code and wrangler.toml configuration. Sets up proper bindings for KV, R2, or Durable Objects if needed. The code follows Cloudflare's patterns and handles common edge cases.

Overview

This skill generates Cloudflare Workers code and wrangler.toml configuration from plain-English prompts. It scaffolds routing, bindings (KV, R2, Durable Objects), environment handling, and common middleware so you get a working edge deployment quickly. Use it when you want one-command generation with minimal setup.

How this skill works

You provide a short description of the Worker you need and the tool outputs Worker JavaScript/TypeScript and a ready-to-use wrangler.toml. It inspects the requested features (KV, R2, Durable Objects, routes, middleware, env vars) and produces appropriate bindings and example code that follow Cloudflare patterns. The output is designed to run locally with wrangler dev and to deploy with minimal edits.

When to use it

Creating latency-sensitive APIs or middleware to run at the edge
Scaffolding Workers with KV or R2 bindings quickly from a description
Learning Cloudflare Workers with practical, runnable examples
Bootstrapping auth, caching, or routing logic for Cloudflare Pages
Generating production-ready wrangler.toml and secret/environment wiring

Best practices

Keep Workers small and focused to stay within edge limits
Use KV for read-heavy data and R2 for larger object storage
Test locally with wrangler dev before deploying to production
Explicitly handle errors and timeouts to make debugging easier
Manage secrets via wrangler or the Cloudflare dashboard, not in code

Example use cases

An API proxy that applies rate limiting and JWT validation at the edge
A geo-based redirect Worker that directs visitors by country
A REST endpoint that stores user preferences in KV
Edge caching for API responses with configurable TTLs
Scaffold Durable Objects for coordination or leader election patterns

FAQ

Do I need to install anything locally?

No install is required to generate code; the tool runs via npx. For local testing and deployment you should have Node.js 18+ and Wrangler configured.

How are secrets and environment variables handled?

The generated project includes placeholders and instructions for wiring secrets via wrangler or the Cloudflare dashboard; do not commit secrets to source control.
