Migrate to Cloudflare Workers from AWS Lambda, Vercel, Express, and Node.js. Use when porting existing applications to the edge, adapting serverless functions, or resolving Node.js API compatibility issues.
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.

# Workers Migration Guide
Migrate existing applications to Cloudflare Workers from various platforms.
## Migration Decision Tree
```
What are you migrating from?
├── AWS Lambda
│ └── Node.js handler? → Lambda adapter pattern
│ └── Python? → Consider Python Workers
│ └── Container/custom runtime? → May need rewrite
├── Vercel/Next.js
│ └── API routes? → Minimal changes with adapter
│ └── Full Next.js app? → Use OpenNext adapter
│ └── Middleware? → Direct Workers equivalent
├── Express/Node.js
│ └── Simple API? → Hono (similar API)
│ └── Complex middleware? → Gradual migration
│ └── Heavy node: usage? → Compatibility layer
└── Other Edge (Deno Deploy, Fastly)
└── Standard Web APIs? → Minimal changes
└── Platform-specific? → Targeted rewrites
```

How to install
mdr add secondsky/claude-skills/cloudflare-workers-migration@sha256:c7d841f4f7e32429The line at the top of this page pins the label v1.0.0, 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.
