GraphQL: What, How and When
summary
GraphQL, the query language created by Facebook, is presented as an alternative to REST to improve scalability and performance by allowing multiple queries in a single request, explicit field selection, and parameterization to reduce latency and data traffic. The talk covers GraphQL features like built‑in documentation and introspection (removing the need for separate tools like Swagger), practical examples, advantages and disadvantages, implementation challenges and lessons learned, and notes growing adoption by companies such as GitHub, Shopify and Brazil’s Cartões Elo.
