No state da função do arquivo REDUCE.TS, eu estou tentando adicionar total: 0 como no código abaixo. Mas ele me mostra o seguinte erro no arquivo STORE.TS. Acho que pode ser do TypeScript, porem não consigo achar o que seria o erro: const initialStatePost: ItemCarrinho = { carrinho: 0, total: 0 } Segue aqui o erro completo: No overload matches this call. Overload 1 of 2, '(reducer: Reducer<ItemCarrinho, any>, enhancer?: StoreEnhancer<unknown, unknown> | undefined): Store<ItemCarrinho, any>', gave the following error.

Type 'ItemCarrinho | { carrinho: number; }' is not assignable to type 'ItemCarrinho'. Property 'totalc' is missing in type '{ carrinho: number; }' but required in type 'ItemCarrinho'. Overload 2 of 2, '(reducer: Reducer<ItemCarrinho, any>, preloadedState?: { carrinho: number; - Segue um exemplo mínimo do código : REDUCE.TS import {ItemCarrinho, TypesCarrinho} from './types' const initialStatePost: ItemCarrinho = { carrinho: 0 } function reducerCarrinho(state = initialStatePost, action: any) { switch(action.type) { case TypesCarrinho.ADD_CARRINHO: return { carrinho: state.carrinho + 1 } case TypesCarrinho.DECREASE_CARRINHO: return{ carrinho: state.carrinho - 1 } default: return state } } export default reducerCarrinho STORE.TS import { createStore } from 'redux' import { composeWithDevTools } from 'redux-devtools-extension' import reducerCarrinho from './ducks/carrinho/reduce' const store = createStore(reducerCarrinho, composeWithDevTools()) export { store } TYPES.TS export enum TypesCarrinho { ADD_CARRINHO = 'ADD_CARRINHO', DECREASE_CARRINHO = 'DECREASE_CARRINHO', } export interface ItemCarrinho{ carrinho: number } ACTION.TS import { action } from 'typesafe-actions' import { TypesCarrinho } from '../../ducks/carrinho/types' export const soma = () => action(TypesCarrinho.ADD_CARRINHO) export const subtracao = () => action(TypesCarrinho.DECREASE_CARRINHO) Continue reading...
