Today, in our modern developer world, it is absolutely impossible to imagine life without such technologies as React, Node JS, GraphQL, and so on. They have solid ranks and are holding leading positions in data delivery. 70% of the cases I come across are projects that are integrated with GraphQL or are about to migrate to it. More and more companies prefer to use the GraphQL data query syntax, and today it is a piece of must-have knowledge.
GraphQL is a query-typed language for API which is widely used for requesting data from the server side to the client side in optimized mater. Clients request exactly what they need using typed schema. It allows you to send only what was requested instead of a fixed dataset.
