Now that we have our basic homepage set up, let’s make the API call to render our list of notes.

Make the Request

Add the following right below the state variable declarations in src/containers/Home.js.

useEffect(() => {
  async function onLoad() {
    if (!props.isAuthenticated) {

    try {
      const notes = await loadNotes();
    } catch (e) {


}, [props.isAuthenticated]);

function loadNotes() {
  return API.get("notes", "/notes");

We are using the useEffect React Hook. We covered how this works back in the Load the State from the Session chapter.

Let’s quickly go over how we are using it here. We want to make a request to our /notes API to get the list of notes when our component first loads. But only if the user is authenticated. Since our hook relies on props.isAuthenticated, we need to pass it in as the second argument in the useEffect call as an element in the array. This is basically telling React that we only want to run our Hook again when the props.isAuthenticated value changes.

And include our Amplify API module in the header.

import { API } from "aws-amplify";

Now let’s render the results.

Render the List

Replace our renderNotesList placeholder method with the following.

function renderNotesList(notes) {
  return [{}].concat(notes).map((note, i) =>
    i !== 0 ? (
      <LinkContainer key={note.noteId} to={`/notes/${note.noteId}`}>
        <ListGroupItem header={note.content.trim().split("\n")[0]}>
          {"Created: " + new Date(note.createdAt).toLocaleString()}
    ) : (
      <LinkContainer key="new" to="/notes/new">
            <b>{"\uFF0B"}</b> Create a new note

And include the ListGroupItem in the header so that our react-bootstrap import looks like so.

import { PageHeader, ListGroup, ListGroupItem } from "react-bootstrap";

Also include the LinkContainer from react-router-bootstrap.

import { LinkContainer } from "react-router-bootstrap";

The code above does a few things.

  1. It always renders a Create a new note button as the first item in the list (even if the list is empty). We do this by concatenating an array with an empty object with our notes array.

  2. We render the first line of each note as the ListGroupItem header by doing note.content.trim().split('\n')[0].

  3. And the LinkContainer component directs our app to each of the items.

Let’s also add a couple of styles to our src/containers/Home.css.

.Home .notes h4 {
  font-family: "Open Sans", sans-serif;
  font-weight: 600;
  overflow: hidden;
  line-height: 1.5;
  white-space: nowrap;
  text-overflow: ellipsis;
.Home .notes p {
  color: #666;

Now head over to your browser and you should see your list displayed.

If you click on each entry, the links should generate URLs with appropriate noteIds. For now, these URLs will take you to our 404 page. We’ll fix that in the next section.

Next up we are going to allow users to view and edit their notes.
