import { createSlice, PayloadAction } from '@reduxjs/toolkit';
import { AppInfo } from '../models';

const initialState: AppInfo | null = null;

const appSlice = createSlice({
  name: 'app',
  initialState,
  reducers: {
    selectApp(state, action: PayloadAction<AppInfo>) {
      return action.payload;
    },
  },
});

export const { selectApp } = appSlice.actions;
export default appSlice.reducer;

export type AppInfo = {
  appName: string;
  createDate: string;
  develop: string;
  op: string;
};

(method) selectApp(state: null, action: PayloadAction<AppInfo>): AppInfo …
