In this introduction to GraphQL, I'll cover specifically the client side usage of GraphQL queries, mutations, and subscriptions. Even with a focus on the client side queries, I will provide a tutorial during this workshop of setting up our sample server side GraphQL API using Hasura. From this an example will be provided of basic data modeling, database schema and design creation in relation to our GraphQL entities, and how all fo this connects. From there I'll add some data, discussing the pros and cons of various structures in relation to GraphQL, and then get into the semantic details of queries, mutations, and subscriptions in GraphQL, with our Hasura API.
