The primary purpose of GraphQL is to provide clients with an efficient and flexible way to retrieve and manipulate data. As a query language, it allows clients to precisely specify the data structure they need, avoiding issues of over-fetching or under-fetching that are common in traditional REST APIs.
Specifically, the main advantages of GraphQL include:
Precise data retrieval: Clients can request exactly the data fields they need, reducing unnecessary data transfer and improving application performance.
Multiple resources in a single request: Clients can obtain data from multiple resources in a single request, rather than sending multiple requests as required in REST APIs.
Flexible data queries: Clients can use nested queries to fetch complex data structures.
Easy integration and scalability: GraphQL servers can easily add or deprecate fields and types without affecting existing queries.
You can quickly understand GraphQL query settings and perform a test using the following example:
Sample Application: GraphQL-query
