Why transition to GraphQL?
Before we get started, let’s dive into GraphQL, looking at how it compares to REST and why we should use it instead of REST.
GraphQL is a query language for APIs. While GraphQL has a single endpoint, typically /graphql, where all queries and mutations are sent, REST relies on multiple endpoints.
With REST, we often encounter the problem of over-fetching or under-fetching data. Over-fetching occurs when the server returns more data than we need, leading to wasted resources and decreased performance. Under-fetching, on the other hand, happens when we need to make multiple requests to retrieve all the data we require, resulting in increased latency.
One of the key advantages of GraphQL is that it solves these issues by allowing the client to define the shape and structure of the response. We can specify the exact fields we want and even retrieve data from multiple resources in a single request. This flexibility empowers clients to optimize their...
