GraphQL is a query language and ecosystem that was launched by Facebook in 2015, providing an expressive way to control retrieved data with a single request, has type-safe API definitions and wide tooling support from big companies like Facebook, Github, Shopify, and more. For backend languages like Python, .Net or Ruby, there hasn't been much adoption of GraphQL API consumption, but Contentful is investing in creating an ecosystem for developers to use GraphQL, introducing GQLi, a GraphQL consumer domain-specific language that allows writing GraphQL queries in native Ruby, providing flexibility and customization. GQLi provides better validation error messages, mutation and subscription capabilities soon, and is actively being worked on with contributions welcome.
