+description: TypeScript patterns for Azure Functions
+---
+
+## Guidance for Code Generation
+- Generate modern TypeScript code for Node.js
+- Use `async/await` for asynchronous code
+- Whenever possible, use Node.js v20 built-in modules instead of external packages
+- Always use Node.js async functions, like `node:fs/promises` instead of `fs` to avoid blocking the event loop
+- Ask before adding any extra dependencies to the project
+- The API is built using Azure Functions using `@azure/functions@4` package.
+- Each endpoint should have its own function file, and use the following naming convention: `src/functions/<resource-name>-<http-verb>.ts`
+- When making changes to the API, make sure to update the OpenAPI schema (if it exists) and `README.md` file accordingly.
