📰 Dev.to · Manas Joshi
Learn to safely handle dynamic API responses using TypeScript Discriminated Unions, ensuring robust and maintainable code
Action Steps
- Define a discriminated union type using the 'discriminate' property
- Create a type guard function to narrow the type of the response data
- Use the type guard function to safely access properties of the response data
- Implement a default case to handle unknown or unexpected response types
- Test the implementation with sample API response data
Who Needs to Know This
Backend developers and API designers can benefit from this technique to improve code reliability and reduce errors when handling API responses
