Call the Create API

Now that we know how to connect to API Gateway securely, let’s make the API call to create our note.

Let’s include our awsLib by adding the following to the header of src/containers/NewNote.js.

import { invokeApig } from "../libs/awsLib";

And replace our handleSubmit function with the following.

handleSubmit = async event => {
  event.preventDefault();

  if (this.file && this.file.size > config.MAX_ATTACHMENT_SIZE) {
    alert("Please pick a file smaller than 5MB");
    return;
  }

  this.setState({ isLoading: true });

  try {
    await this.createNote({
      content: this.state.content
    });
    this.props.history.push("/");
  } catch (e) {
    alert(e);
    this.setState({ isLoading: false });
  }
}

createNote(note) {
  return invokeApig({
    path: "/notes",
    method: "POST",
    body: note
  });
}

This does a couple of simple things.

1. We make our create call in createNote by making a POST request to /notes and passing in our note object.

2. For now the note object is simply the content of the note. We are creating these notes without an attachment for now.

3. Finally, after the note is created we redirect to our homepage.

And that’s it; if you switch over to your browser and try submitting your form, it should successfully navigate over to our homepage.

Next let’s upload our file to S3 and add an attachment to our note.
