Dependent Types vs Contracts
Developers should learn dependent types when working on safety-critical systems, formal verification, or high-assurance software where correctness is paramount, such as in aerospace, finance, or medical devices meets developers should learn and use contracts to build more robust and maintainable software, especially in large-scale or distributed systems where components interact. Here's our take.

Dependent Types
Nice PickDevelopers should learn dependent types when working on safety-critical systems, formal verification, or high-assurance software where correctness is paramount, such as in aerospace, finance, or medical devices
Pros
- +They are valuable for eliminating runtime errors by encoding logical constraints directly into the type system, reducing debugging time and increasing confidence in code
- +Related to: type-theory, functional-programming
Cons
- -Specific tradeoffs depend on your use case
Contracts
Developers should learn and use contracts to build more robust and maintainable software, especially in large-scale or distributed systems where components interact
Pros
- +They are crucial for preventing bugs, enabling automated testing, and documenting APIs clearly, making them valuable in scenarios like microservices, library development, or safety-critical applications
- +Related to: design-by-contract, assertions
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Dependent Types if: You want they are valuable for eliminating runtime errors by encoding logical constraints directly into the type system, reducing debugging time and increasing confidence in code and can live with specific tradeoffs depend on your use case.
Use Contracts if: You prioritize they are crucial for preventing bugs, enabling automated testing, and documenting apis clearly, making them valuable in scenarios like microservices, library development, or safety-critical applications over what Dependent Types offers.
