Let's make a contract: the art of designing a Java API by Mario Fusco
Designing a Java API that is easy to use, maintainable, and adaptable to changing requirements. Learn best practices for API design, from understanding future needs to using fluent APIs, and creating readable and concise code.
- API design is an iterative process that involves understanding the future needs of your module or product.
- Avoid overloading methods with multiple signatures and use meaningful names instead.
- API documentation should be clear, concise, and written with the end user in mind.
- Use static factory methods instead of constructors to provide more flexibility.
- Avoid using null as a return value and instead use optional values.
- Consistency in naming conventions and coding style is important for readability and maintainability.
- API design should prioritize the principle of least astonishment to prevent unexpected behavior.
- Modular reasoning is essential for designing APIs that are easy to use and maintain.
- Limit the number of entry points in your API to prevent informational overload.
- Use fluent APIs to create more readable and concise code.
- Avoid using technical jargon and instead use plain language to describe your API.
- API design should be flexible and able to accommodate changing requirements.
- Documentation should be written in a way that is easy for others to understand.
- Use type annotations to clearly indicate the expected type of a variable.
- Avoid using too many method signatures and instead provide a single clear way to accomplish a task.
- Use meaningful variable names to make code more readable.
- Avoid premature optimization and instead focus on writing clean, maintainable code.
- API design should prioritize ease of use and readability over optimization.
