Why GraphQL API?

GraphQL is a modern API query language designed to address several challenges developers face when building applications. It provides a standardized approach for building rich, complex experiences across multiple platforms and devices, simplifying the process for developers. All GraphQL servers follow a specification that offers essential patterns beneficial to application development:

​
Field Selection

This pattern requires the client to explicitly specify which fields it wants in the response, reducing payload size by ensuring only requested data is returned. This leads to faster, more efficient data exchanges.

​
Resource Aggregation

Through resource aggregation, clients can traverse and access multiple related fields in a single request, reducing the need for multiple server calls and creating a smoother user experience by bundling related resources within a single response.

​
Schema Introspection

Introspection allows clients to query the GraphQL server to discover details about the schema, such as types, fields, and relationships. This feature enables developers to better understand and work with the schema, creating more robust and adaptable applications.

​
Additional Features of GraphQL API

  • GraphQL provides representations of data objects in line with user permissions, ensuring that users only see data they have permission to access. Different users may see different schemas based on their access rights.
  • It supports the Relay Connection Specification for working with paginated resources.
