Each has advantages and disadvantages, or strengths and weaknesses, in terms of API architecture, when it comes to REST and GraphQL.
Below is the strength and weakness for both REST and GraphQL.
REST
- Works well when you need straightforward, consistent interfaces between different services or applications. - Uses standard HTTP methods like GET, POST, PUT, and DELETE for CRUD operations.
- Implementing caching strategies is simple.
- The drawback is that gathering relevant data from various endpoints might necessitate making several round trips.
GraphQL
- Gives clients access to a single endpoint where they can query for the exact data they require.
- In nested queries, clients define the precise fields they need, and the server returns optimised payloads with only those fields.
- Allows subscriptions for in-the-moment notifications and mutations for changing data. Excellent at combining data from several sources and adapting quickly to changing front-end needs.
- But if not adequately protected, it transfers complexity to the client side and opens the door to abusive inquiries. Compared to REST, caching strategies can be more intricate.
Conclusion -
The particular needs of the application and development team will determine which of REST and GraphQL is the better option. REST is more appropriate for applications where clear and unambiguous contracts are desired, whereas GraphQL is a better fit for complicated or dynamic frontend requirements.
