This review focuses on ensuring robust and type-safe usage of the Axios library in TypeScript codebases. Key recommendations: 1. Leverage Axios' built-in type-checking utilities rather than relying on error-prone `instanceof` checks. Use `axios.isCancel()` to detect canceled requests instead of manual type checking. 2. Properly handle Content-Type headers when sending data. Document how Axios automatically manages Content-Type for different data types (e.g. JSON, form data, URL-encoded). Provide clear examples of correct data transformation before sending, such as using `URLSearchParams` for URL-encoded form data. 3. Standardize serialization patterns for complex data types like `FormData` and nested objects to ensure consistent data handling across the codebase. Following these practices will help ensure your Axios-based APIs remain robust and maintainable when used in applications with varying dependency versions, environments (browser/Node.js), and data formats.
