Visão Geral
O curso GraphQL API on a Front-End React App foi desenvolvido para capacitar desenvolvedores na construção de aplicações modernas utilizando React integrado a APIs GraphQL.
Durante o treinamento, o aluno aprenderá como consumir queries, mutations e subscriptions diretamente no front-end, utilizando Apollo Client, gerenciar estado com cache inteligente e otimizar a experiência de ponta a ponta entre UI e API.
Ao concluir o curso, o participante será capaz de criar aplicações React altamente performáticas, escaláveis e organizadas, integradas com APIs GraphQL reais.
