GraphQL Nodes And Edges Explained

Getting a rudimentary understanding of graph theory can go a long way in solidifying your understanding of nodes and edges in GraphQL.

What is a graph?

In simple terms, a graph is an interconnected web of data. Each data point (e.g. books or authors) represents a node and each of these nodes is connected by what are called edges.

It's important to note that edges are just as important as nodes as they contain metadata about the relationship of two nodes.
