Starting with GraphQL

The Power of GraphQL

• Consumer defines the data structure it wants to receive in a query
• JSON-like query structure (with intell-sense)

What is GraphQL?

• An open-source specification (created by Facebook) to access data in APIs
• GraphQL consumer (quereis) -> GraphQL API runtime (processes the query)
• GraphQL API vs. REST API
• GraphQL specification is not tied to HTTP
