States, props and React Native Gerindo o fluxo de informação
na sua aplicação de forma inteligente
Quem? Caio Lucas Alcântara - @clucasalcantara Mobile Software Engineer
ONE WAY DATA FLOW
React Native Component LifeCycle
State and Props Variáveis utilizadas para controlar as informações que
fluem na interface.
State Estado, literalmente. Representa tudo o que está "instanciado" na
sua aplicação. Sua atualização dispara o render.
Props Informações recebidas na construção do componente, herdadas pelo pai,
imutáveis.
Evite modelar o state baseando-se na API:
None
Nunca guarde dados derivados do seu estado A idéia é
aproveitar os side effects condicionados
Seu state deve ser um cidadão de primeira classe Imperativo
versus Declarativo versus Reativo
Vai dar merda, sempre dá :)
Abordagens com JS para facilitar a manipulação do fluxo Router
Flux React Navigation Flux ...
ES6/7 Destructuring Arrow functions Async Await ...
None
Gerenciadores de States Frameworks criados para auxiliar na manipulação de
estados durante a sua aplicação
None
Abstração é bom! Mas não pra aprendizado!! Cuidado ao "caixa
pretar" as coisas.
Obrigado, gente!!
