notes.map is not a function

[Jawad-Ali2]

The code works fine till video#71. But changes in noteState.js headers: { 'Content-Type': 'application/json', "auth-token": localStorage.getItem('token') } caused this issue. If I remove the localStorage line and write the previous line (the auth token we used on the endpoint) the app works fine. Kindly, someone help me with this issue, I've been facing for 1 week now. Thanks.

One way I found is: Array.from(notes).map((note) => {}

But after this I am unable to fetch notes on my main page.

hey you guys can use this code - {Notes ? Notes.map((i) => ( <>

{i.title}

</>)) :"No notes available"}

{notes.length>0? notes.map((note)=>{ return ; }):

No Notes to Display

} You can use this it just checks whether the notes array length is 0 or greater if its zero is prints no notes to display else it renders all the notes.

check your auth.js file and fetchuser.js file in backend. you might have written auth-token. simple write auth-token instead of token in localStorage.getItem('auth-token') in NoteState.js,login.js,signup.js.,Notes.js and Navbar.js. Also replace the json.authtoken with authToken in Login.js and Signup.js. hope this will help you

Here is solution

import React, { useContext, useEffect } from 'react'; import noteContext from '../context/notes/noteContext'; import Noteitem from './Noteitem'; import AddNote from './AddNote'; import { useNavigate } from 'react-router-dom';

const Notes = () => { const navigator = useNavigate(); const context = useContext(noteContext); const { notes, getNote } = context;

console.log("notes"); console.log(typeof(notes));

useEffect(() => { getNote(); // eslint-disable-next-line react-hooks/exhaustive-deps }, []); // Make sure to pass an empty dependency array to run this effect only once

return ( <>

  <div className="row my-3">
    {!localStorage.getItem("token") ? navigator('/login')
     :  Array.isArray(notes) && notes?.map((note) => {
      // return <div key={note.id}>{note.title}</div>;
      return <Noteitem key={note._id} note={note} />
    })
    }
  </div>
</>

); };

export default Notes;
