I'm a little confused how a 0.005% registry share implies that 2019 is the year of GraphQL. If we extrapolate from some other numbers in the study (React has 0.05% registry share and 60% market share among frameworks) we can gather that about 6% of developers using a framework are also using GraphQL (assuming everyone using GraphQL is using some framework). It seems like this study is seriously overhyping the prominence of GraphQL, and I'm not convinced it'll hit mainstream this year or next.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
