What are the main advantages and disadvantages of using GraphQL compared to REST API?

Advantages of GraphQL compared to REST API:

• Clients can request exactly the data they need, without over-fetching.
• One endpoint instead of many, simplifying management.
• Ability to fetch related data in a single request.
• Well-suited for complex and dynamic interfaces.

Disadvantages of GraphQL:

• More complex server setup and caching.
• Potentially higher server load due to complex queries.
• Fewer tools and standards compared to REST.
• Requires team training and architectural changes.

While REST is simpler and widely used, GraphQL offers flexibility in queries and data transfer optimization, especially useful in mobile apps with limited bandwidth.
