GraphQL Open-Sourced by Facebook

Facebook officially open-sourced GraphQL, a data query language and runtime for APIs, initially developed internally to power its mobile applications. This move made the technology available to the wider developer community.

Significance

This event laid the conceptual groundwork for AppSync. GraphQL's paradigm-shifting approach to API design, allowing clients to request exactly the data they need, directly inspired AWS to build a managed service around it to address common developer pain points.
