React: props is not defined

Question

I have the following code in a product, js, I'm trying to return a single item on API call using the id param. When I run I get props not defined. I don't know how to solve this

import React, {useEffect }from 'react';

import { detailsProduct } from '../actions/productActions';
  
function Productscreen(props) {

const productDetails = useSelector(state => state.productDetails);

const {product , loading, error } = productDetails;

const dispatch = useDispatch();
useEffect(() => {

  dispatch(detailsProduct(props.match.params.id));

  return () => {
    //
  }
}, [])

The way you pass the component to your route matters. To have access to match, you would have needed the render prop to destructure the match.

<Route path='/whatever/:id' render={({match}) => <Productscreen match={match} />} />

You can also use the new react router hooks useParams, I prefer them, mostly because of Typescript.

import React, {useEffect } from 'react';
import { detailsProduct } from '../actions/productActions';
import { useParams } from "react-router-dom";

function Productscreen() {
    const productDetails = useSelector(state => state.productDetails);
    const {product , loading, error } = productDetails;

    let { id } = useParams()

    const dispatch = useDispatch();

    useEffect(() => {
         dispatch(detailsProduct(id));`

          return () => {
                //
          }
    }, [])
}

in that case, your route should be:

<Route path="/whateverpath/:id">
  <Productscreen/>
</Route>
