The History of GraphQL

GraphQL, much like React, was originally developed by Facebook. The initial development started in 2012, but it wasn't until 2015 that GraphQL was publicly released. When Facebook decided to make GraphQL open source, the project was eventually transferred to the GraphQL Foundation, which is hosted by the Linux Foundation, in 2018.

GraphQL was created out of Facebook's need to improve the scalability of their mobile app. Initially, Facebook's mobile strategy was to adapt their website for mobile use by leveraging HTML5. However, this approach led to challenges such as high network usage and a suboptimal user experience. To address these issues, Facebook's development team decided to rebuild their iOS app using native technologies.
