React Typescript - 类型参数不可分配给“SetStateAction”类型的参数<user | record<string, never> >'</user>

Question

I have a simple React web app with data (List of object) of Users, Todos And Posts, where I show, update and delete the data.

I have a Component named UserView where I get the user data from the props, and then I save the data in the state with useEffect

interface UserViewProps {
  userData: User;
}

export default function UserView({
  userData,
...
}: UserViewProps) {
  const [user, setUser] = useState<User | Record<string, never>>({});
  useEffect(() => {
...
    setUser({ ...userData });
  }, [todosData]);

The problem is when I want to change the user state from input to pass to a callback function with destructuring:

<input
        onChange={(e) =>
          setUser({
            ...user,
            name: e.target.value,
          })
        }

I receive the following TypeScript error:

Argument of type '{ name: string; id: number; username: string; email: string; address: Address; phone: string; website: string; company: Company; } | { name: string; }' is not assignable to parameter of type 'SetStateAction<User | Record<string, never>>'.
Type '{ name: string; }' is not assignable to type 'SetStateAction<User | Record<string, never>>'.
Type '{ name: string; }' is not assignable to type 'Record<string, never>'.
Property 'name' is incompatible with index signature.
Type 'string' is not assignable to type 'never'.ts(2345)

When I change

 const [user, setUser] = useState<User | Record<string, never>>({});

to

  const [user, setUser] = useState<User | any>({});

Everything works How can I fix this TypeScript error?

Full code below:

import React, { useEffect, useState } from 'react';
import { Post, Todo, User } from '../../../helpers/utils';
import { StyledUserView } from './style';

interface UserViewProps {
  userData: User;
  todosData: Todo[];
  postsData: Post[];
  handleUserDelete: (userId: number) => void;
  handleUserUpdate: (updatedUser: User) => void;
}

export default function UserView({
  userData,
  todosData,
  postsData,
  handleUserDelete,
  handleUserUpdate,
}: UserViewProps) {
  const [isUncompletedTodo, setIsUncompletedTodo] = useState(false);
  const [isShowOtherData, setIsShowOtherData] = useState(false);
  const [user, setUser] = useState<User | any>({});
  useEffect(() => {
    if (todosData.find((todo) => todo.completed === false)) {
      setIsUncompletedTodo(true);
    } else {
      setIsUncompletedTodo(false);
    }
    setUser({ ...userData });
  }, [todosData]);
  return (
    <StyledUserView isUncompletedTodo={isUncompletedTodo}>

Answer 1

You can try to change

const [user, setUser] = useState<User | Record<string, never>>({});

// to 
const [user, setUser] = useState<User | Record<string, any>>({});

//or 
const [user, setUser] = useState<User | Record<string, string>>({});

Answer 2

Add inital user name as empty string

  const [user, setUser] = useState<{ name: string }>({
    name: ""
  });

code sanbox

Answer 3

if the name is a variable then you need to do [name] else it is static then "name"

 <input
 onChange={(e) =>
  setUser(prv=>{
   ...prv,
    [name]: e.target.value,
   })
}
