Understanding GraphQL Concepts

GraphQL is a query language and runtime for APIs that enables clients to request only the data they need. It differs from traditional REST APIs in several key ways.

Important Concepts:

1. Schema

• Types: Defines the structure of data.
• Queries: Retrieves data from the server.
• Mutations: Alters data on the server.
• Subscriptions: Listens for real-time data changes.

2. Resolvers

• Functions that resolve data for different parts of the GraphQL schema.
• Resolver is Provide the Data, and that Data is Co-related the The Schema or Type that we're created.

3. Queries and Mutations

• Query: Fetches data from the server.
• Mutation: Modifies data on the server.

4. GraphQL Playground

• An interactive tool for testing and debugging GraphQL APIs.

5. Packages are used so Far

• I used the @apollo/server, graphql
• where apollo/server basically used to run the server
