GraphQL variables in simple terms

GraphQL, a query language for APIs, is gaining popularity among companies for its ability to enhance developer experience by allowing dynamic and flexible data queries through the use of variables. This flexibility is demonstrated using GitHub's public API to show how queries and mutations can be written with variables, enabling the reuse of queries with different parameters without reconstructing them each time. The text explains how to define and use variables in GraphQL queries and mutations, including assigning default values, which offers the benefit of reusability and dynamic querying capabilities. The article also highlights the ease of verifying query outcomes by checking real-time updates on platforms like GitHub and underscores the importance of tools like LogRocket in monitoring GraphQL requests in production environments, ensuring reliability and efficient debugging.
