lot of information has been written about GraphQL since it was unleashed to the world by Facebook in 2015. As the curious nerds we are, we tend to embrace the self-taught approach first, which implies research, reading documents and tutorials, and more documents and tutorials, and trying/error in a continuous loop, until we feel confident with the topic.

lot of information has been written about GraphQL since it was unleashed to the world by Facebook in 2015. As the curious nerds we are, we tend to embrace the self-taught approach first, which implies research, reading documents and tutorials, and more documents and tutorials, and trying/error in a continuous loop, until we feel confident with the topic.
The intention of this road map is to share with you our own learning experience (one of many paths you can take to grok the language) and to draw you to the highest quality information (which we won't be ever able to write in a better way) in the attempt to prevent you from coming across misleading (when not completely wrong) documents outside in the wild; and keeping you on the implementation agnostic spirit of the language, providing abstract examples as well as practical exercises in different languages so you can understand the correlations and differences without losing focus on the main topic: GraphQL.

We'll walk through this starting from the language and the API definition on the backend, gradually increasing the complexity as the walk develop; it might contain new examples on the future, or more "days" including client-side, testing or architecture specific topic, or we might create another walk for them, we don't really know.

Hopefully your walk will be much easier than ours! Mostrar menos

The intention of this road map is to share with you one of many paths you can take to grok the language and specially to draw you to the highest quality information (which I won’t be ever able to write in a better way) in the attempt to prevent you from coming across misleading (when not completely wrong) documents outside in the wild.
