GraphQL vs REST: Choosing the Right API Style

The debate between GraphQL and REST is often heated. Both have their place in modern web development.

REST (Representational State Transfer)

REST is the traditional approach, relying on standard HTTP methods and resources.

• Pros: Simple, cacheable, widely understood.
• Cons: Over-fetching and under-fetching of data.

GraphQL

GraphQL allows clients to request exactly the data they need.

• Pros: Efficient data loading, strongly typed schema.
• Cons: Complexity in caching, potential for n+1 query problems.

When to Use Which?

• Use REST for public APIs with simple data requirements and heavy caching needs.
• Use GraphQL for complex applications with interrelated data and diverse client needs (mobile, web, etc.).
