Manage with React api query useState Hook

Question

After creating useState Hook For gender, age useState('30'); useState('female'); If you set

http://api.minsu.com/product/${id}?gender=feamle&age=30

I am using react-query(useQuery) for api state management library. It's no different, I'm creating a dynamic page right now and then showing the page based on the id value.

This is an example.

https://api.minsu.com/product/${id}

And on the detailed page, http://api.minsu.com/product/${id}?gender=feamle&age=30 In this way, random data is entered for gender and age, and only specific data of a 30-year-old woman is shown.

select box (option) After choosing female and age as Set the api to https://api.minsu.com/product/${id}?gender=${gender}&age=${age} I want to show the detail page after receiving gender and age through api get according to the selected select by modifying it in this way.

It seems that I am not directly using input and select box, and I do not know how to write query using useState Hook.

But I don't know what to do.

This is my code now.

I thought about it for about an hour. I have created age and gender with setState('').

    const [gender, setGenders] = useState('female');
    const [age, setAges] = useState('30');


   const fetchDetail = async () => {
        const res = await 
        fetch(`https://api.minsu.com/product/${id}?gender=${female}&age=${age}`, {
            headers: {
                Authorization: `Bearer ${token}`,
            },
            withCredentials: true 
        });
        return res.json();
    }

    const { data: ProductDetail, status, error, isFetching } = useQuery('productDetail', fetchDetail, {
        notifyOnChangeProps: ['data'], 
        staleTime: 100000000,
    })
    console.log(ProductDetail);

return (
 

 <input type="number" placeholder={Enter your age} .... />
 <button onClick={onClick} />
 

 <option>Select gender</option>
    <option value="male">Male</option>
    <option value="female">Female</option>
)

That is, to summarize

const [inputs, setInputs] = useState({
        age: '30',
        gender: 'female',
    })
    const {age, gender} = inputs; 

    const onChange = (e) =>{ 
        setInputs({ ...inputs, [e.target.age]:e.target.value }) 
    }

  return (
 <input name="age" onChange={onChange} placeholder = "age"/> 
            <input name="gender" onChange={onChange} placeholder = "gender"/>

)

I want to change the query by executing onChange after creating the input, but the rendering is not working.

Answer 1

Assuming you're updating the local state (age and gender) correctly and just need to trigger the query again.

Query Basics

To subscribe to a query in your components or custom hooks, call the useQuery hook with at least:

• A unique key for the query
• A function that returns a promise that:
  • Resolves the data, or
  • Throws an error

The unique key you provide is used internally for refetching, caching, and sharing your queries throughout your application.

If your query function depends on a variable, include it in the query key.

Given the request URL:

`https://api.minsu.com/product/${id}?gender=${gender}&age=${age}`

Then id, age, and gender should all probably be included as part of the query key.

const {
  data: ProductDetail,
  status,
  error,
  isFetching,
} = useQuery(
  ['productDetail', id, age, gender],
  fetchDetail,
  {
    notifyOnChangeProps: ['data'], 
    staleTime: 100000000,
  },
);

Answer 2

you can use this (check my comments inside snippet):

import { useQueryClient } from "@tanstack/react-query";

const [id, setId] = useState("someId") // you don't say what should we do with id?!
const [age, setAge] = useState("30")
const [gender, setGender] = useState("female")

const onAgeChange = (e) => {
  setAge(e.target.value) // you used: e.target."""age"""!
}
const onGenderChange = (e) => {
  setGender(e.target.value) // you used: e.target."""age"""!
}

const {
  data: ProductDetail,
  status,
  error,
  isFetching,
} = useQuery(
  ['productDetail', id, age, gender],
  fetchDetail,
  {
    notifyOnChangeProps: ['data'],
    staleTime: 100000000,
  },
);

const queryClient = useQueryClient();
useEffect(() => {
  queryClient.invalidateQueries(['productDetail', id, age, gender]); // this will update your data automatically if id, age and/or gender change
}, [id, age, gender])

return (
  <>
    <input name="age" onChange={onAgeChange} value={inputs.age} placeholder="age" /> {/*  you missed the """value={}""" */}
    <input name="gender" onChange={onGenderChange} value={inputs.gender} placeholder="gender" /> {/*  you missed the """value={}""" */}
  </>
)
