This project attempts to analyze npm package contents for issues with their TypeScript types, particularly ESM-related module resolution issues. Packages can be explored via the website or CLI. The following kinds of problems can be detected in the node10, node16, and bundler module resolution modes:
- 💀 Resolution failed
- ❌ No types
- 🎭 Masquerading as CJS
- 👺 Masquerading as ESM
⚠️ ESM (dynamic import only)- 🐛 Used fallback condition
- 🤨 CJS default export
- ❗️ Incorrect default export
- ❓ Missing
export = - 🚭 Unexpected module syntax
- 🥴 Internal resolution error
You can check packages on disk with @arethetypeswrong/cli. See its README for usage.
