Cloudflare Workers local development with Wrangler, Miniflare, hot reload, debugging. Use for project setup, wrangler.jsonc configuration, or encountering local dev, HMR, binding simulation errors.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cloudflare Workers Developer Experience
Local development setup with Wrangler, Miniflare, and modern tooling.
## Quick Start
```bash
# Create new project
bunx create-cloudflare@latest my-worker
# Or from scratch
mkdir my-worker && cd my-worker
bun init -y
bun add -d wrangler @cloudflare/workers-types
# Start local development
bunx wrangler dev
```
## Secure Installation
Scaffolding tools like `bunx create-cloudflare` download and execute remote code. Before running, follow supply chain security best practices:
- **Block post-install scripts** — `npm config set ignore-scripts true` (or Bun: disabled by default)
- **Cooldown period** — Wait 7 days for new package versions to be vetted by the community
- **Audit before installing** — Run `socket package score npm <pkg>` or use `socket npm install <pkg>` to check packages
Load the `dependency-upgrade` skill for full security configuration including Socket CLI integration, cooldown setup, lockfile validation, and CI enforcement.
## Essential wrangler.jsonc
```jsonc
{
"$schema": "node_modules/wrangler/config-schema.json",
"name": "my-worker",
"main": "src/index.ts",
"compatibility_date": "2024-12-01",

How to install
mdr add secondsky/claude-skills/cloudflare-workers-dev-experience@sha256:4999b810bc627e0dThe line at the top of this page pins the label git:20260514.120edd6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
