Executing Simple GraphQL Queries
Practice constructing and executing basic queries to retrieve data using tools like GraphiQL or GraphQL Playground.
What are GraphQL Queries?
Welcome to executing GraphQL queries! In this lesson, we'll learn how to fetch data from a GraphQL server.
A GraphQL Query is how a client application asks the server for data. Unlike traditional REST APIs where you often get fixed data structures, GraphQL lets you specify exactly what data you need.
Interactive Query Tools
To execute queries, we often use interactive tools. Two popular ones are GraphiQL and GraphQL Playground.
- These are browser-based IDEs (Integrated Development Environments).
- They provide features like schema exploration, auto-completion for queries, and documentation.
- They connect to your GraphQL server's endpoint to send queries and display results.
