Choosing Between REST and RPC: A Guided Decision
When designing a distributed API, you may find yourself pondering whether to choose REST (Representational State Transfer) or RPC (Remote Procedure Call). Both have their unique attributes and best-use cases. Let's break down how to make this decision based on your specific needs.
1. When Your API is Mostly Actions
Prefer RPC
- How it works: RPC focuses on invoking remote procedures or actions, often representing functions or methods.
- Why choose this: If your API is primarily about performing specific actions or tasks, RPC is designed to accommodate that behavior.
2. When Your API is Mostly Manipulating Structured Data
Prefer REST
- How it works: REST revolves around manipulating resources, using standard HTTP methods like GET, POST, PUT, and DELETE.
- Why choose this: If your API deals mainly with structured data and adheres to the stateless and uniform interface principles, REST is the natural fit.
3. When Your API is a Mix of Both
It's OK to Use Both Styles
- How it works: You don't have to lock yourself into one paradigm. Combining REST and RPC can provide the flexibility to handle both actions and data manipulation.
- Why choose this: If your API requires the strengths of both REST and RPC, mixing the styles can offer a more nuanced and responsive design.
The choice between REST and RPC doesn't have to be a binary one. By understanding the nature of your API and what you want to achieve, you can make an informed decision that best aligns with your goals. Remember, being pragmatic and open to using both styles can sometimes lead to a more effective and adaptable API design.
