Getting Started

What is GraphQL 

 GraphQL is an API query language. 

 It lets the client ask exactly for the data it needs. No more. No less. 

 Main ideas: 

 One endpoint. Client chooses fields. Strong types. Clear schema. 

 GraphQL replaces many REST endpoints with one structured API. 

 

 What We Use in Finmars 

 In Finmars, GraphQL is built with: 

 Django Strawberry GraphQL https://github.com/strawberry-graphql/strawberry 

 Strawberry is a Python GraphQL library. It works well with Django models. It uses Python type hints to define the schema. 

 Key points: 

 Schema is written in Python. Types are strict. Queries are validated before execution. Errors are clear.
