GraphQL is a language for querying data,we can use it to query data from any number of different sources.
In GraphQL , there are ?queries?and?mutations.Queries that?fetch data?are synonymous to?GET?calls in REST, while mutations signal that we’d like to invoke a?change?the in system, similar to REST’s?POST?or?DELETE?methods.
GraphQL is typically served over HTTP
On the server, we create a GraphQL schema based on the data we need to build our app UIs
We can write our query, specifying precisely what you’d like to fetch.
