Data Fetching with GraphQL 🚀

GraphQL is an open-source query language developed by Facebook that allows for flexible and efficient data fetching. It integrates seamlessly with various environments like Express with Node.js, and provides a declarative way to fetch data. This means that it only requests what the client actually needs, ensuring minimal data transmission and faster performance.

Key Benefits of GraphQL:
- 🚀 Single Endpoint: Unlike REST which has multiple endpoints, GraphQL uses a single endpoint for all queries.
- 🚀 Efficiency: Only the requested data is sent over the network, eliminating unnecessary data transmission.
- 🚀 Client-Side Acceleration: Fewer round trips between client and server as GraphQL can batch requests into a single query.

Syntax - Schema Definition Language (SDL):
GraphQL uses Schema Definition Language (SDL) to define the shape and structure of the data. This allows developers to clearly specify the types and queries needed for interaction with a database (e.g., MongoDB Atlas).

Example:
After setting up your server, you can spin it up with:

`node server.js`

Once running, the GraphQL console can be accessed via a link in your terminal. Here, you can execute queries against the schema and directly interact with your data.

GraphQL is particularly powerful when handling complex queries or working with multiple sources of data, making it a great choice for modern web applications.
