Uma boa forma de utilizar formulário no Remix, é utilizando o pacote remix-hook-form. Que utiliza bases do pacote react-hook-form considerada a melhor para tratamento de formulário.
Link para a documentação do pacote remix-hook-form:
https://github.com/Code-Forge-Net/remix-hook-form
Como o formulário precisar ser tratado tanto no lado do servidor quanto no lado do cliente, o autor Alem Tuzlak criou esta biblioteca.
Eu testei ela e achei muito boa. Antes de testar eu estava planejando criar meu próprio pacote para tratamento de formulário utilizando qualquer tipo de validador.
No momento em que estava procurando mais informações, lembrei do pacote react-hook-form e acabei me deparando com o pacote remix-hook-form . Minha experiência, foi a melhor.
Antes de tudo, você precisa instalar os seguintes pacotes:
pnpm add remix-hook-form react-hook-form @hookform/resolvers zod
Abaixo esta uma página que trata múltiplos formulários e faz validação tanto no lado do cliente, como no lado do servidor.
Utilizei intent para diferenciar os formulários em uma única rota. Utilizei o componente Form e também utilizar fetcher .
