List All the Notes

Now that we are able to create a new note, let’s create a page where we can see a list of all the notes a user has created. It makes sense that this would be the homepage (even though we use the / route for the landing page). So we just need to conditionally render the landing page or the homepage depending on the user session.

Currently, our Home container is very simple. Let’s add the conditional rendering in there.

Replace our src/containers/Home.js with the following.

import React, { useState, useEffect } from "react";
import ListGroup from "react-bootstrap/ListGroup";
import { useAppContext } from "../lib/contextLib";
import { onError } from "../lib/errorLib";
import "./Home.css";

export default function Home() {
  const [notes, setNotes] = useState([]);
  const { isAuthenticated } = useAppContext();
  const [isLoading, setIsLoading] = useState(true);

  function renderNotesList(notes) {
    return null;
  }

  function renderLander() {
    return (
      <div className="lander">
        <h1>Scratch</h1>
        <p className="text-muted">A simple note taking app</p>
      </div>
    );
  }

  function renderNotes() {
    return (
      <div className="notes">
        <h2 className="pb-3 mt-4 mb-3 border-bottom">Your Notes</h2>
        <ListGroup>{!isLoading && renderNotesList(notes)}</ListGroup>
      </div>
    );
  }

  return (
    <div className="Home">
      {isAuthenticated ? renderNotes() : renderLander()}
    </div>
  );
}

We are doing a few things of note here:

1. Rendering the lander or the list of notes based on isAuthenticated flag in our app context.

   {isAuthenticated ? renderNotes() : renderLander()}
   

2. Store our notes in the state. Currently, it’s empty but we’ll be calling our API for it.

3. Once we fetch our list we’ll use the renderNotesList method to render the items in the list.

4. We’re using the Bootstrap utility classes pb-3 (padding bottom), mt-4 (margin top), mb-3 (margin bottom), and border-bottom to style the Your Notes header.

And that’s our basic setup! Head over to the browser and the homepage of our app should render out an empty list.

Next we are going to fill it up with our API.
