golang interfaces best practices
Where should Golang interfaces be defined?
Golang Wiki says: "Go interfaces generally belong in the package that uses values of the interface type, not the package that implements those values."
Should I use interfaces in Golang?
There are all sorts of reasons that you might end up using a interface in Go, but in my experience the three most common are:
To help reduce duplication or boilerplate code.To make it easier to use mocks instead of real objects in unit tests.One-method interfaces are named by the method name plus an -er suffix or similar modification to construct a noun.
Eg.
Reader , Writer , etc. use MixedCaps or mixedCaps rather than underscores to write multiword names.
What are the best practices for interfaces in Go?
Best practices for designing interfaces in Go include: using small and focused interfaces with a single responsibility, following the Single Responsibility Principle, naming interfaces based on their behavior, making interface methods clear and concise, and designing interfaces that are easy to understand and implement 27 jui. 2023
