I can't get the props.match.params.id. It's said props is undefined

I've tried to get the id from the URL (with props.match.params.id) and pass it into a variable to reuse it. But props is undefined. I don't know why.

Anyone can see if I've done something wrong?

import React, { useState, useEffect } from "react";
import axios from "axios";

export default function Recipes() {
  const [recipes, setRecipes] = useState([]);
  useEffect(() => {
    const id = props.match.params.id;
    const getRecipes = async () => {
      const url = `http://localhost:8000/user/recipes/${id}`;
      const result = await axios.get(url);

      setRecipes(result.data);
      console.log("test", recipes);
    };
    getRecipes();
  }, []);

  return (
    <div>
      {recipes.map(recipe => (
        <p>{recipe.title}</p>
      ))}
    </div>
  );
}

You need to make use of the useParams hook from react-router-dom for this instead.

Try this:

...
import { useParams } from 'react-router-dom'

export default function Recipes() {
  ...
  const { id } = useParams()
  
  useEffect(() => {
    ...
  }, [id])
  ...
}

I think you forgot to add props in your functional component :

You can solve the error "It's said props is undefined"

By Change this :

export default function Recipes() {

TO

export default function Recipes(props) {

Ah! I think you forget it add props as a param to you component. This is something I do very often.

Your component should be like this 


export default function Recipes(props) {

//Your content

}
